Proto21 Pledges Support to fight Covid-19 pandemic
As the novel coronavirus disease continues to spread, healthcare workers and other industry professionals are facing a big shortage for protective face shields and other medical devices. According to World Health Organization the best way to prevent and slow down the transmission of COVID-19 virus is to take the necessary precautions. The virus gets spread through a droplet from an infected person through coughing or sneezing and try to enter the host through their nose or mouth. That’s where it’s paradise is and that is where the face shields come into action. It is no rocket science, the bottom line is to block the virus droplets from entering your body and experts around the globe has seen a lot of success with 3D printed face shields.
Understanding the current requirement for the 3D printed face shields in UAE, Proto21 has completely turned over our 3D printing facility into a manufacturing site for these 3D Printed Protective Equipments. The 3D printed face shields are manufactured with our HP Multi Jet Fusion technology using medical grade bio compatible PA12 Nylon Powder. This advanced manufacturing technology has helped us to maximize the production capacity by increasing the number of parts printed at a time for a lower cost. Right now we have healthcare worker professionals and others using our face shields.

3D Printed Figurines widely knows us ‘mini-me’ or ‘3D Selfies’ are a 3D printed miniature figurine of a person based on their 2D pictures or a photorealistic scan. The demand for 3D Figurines have rapidly grown over the years as end users have become more and more excited about the technology and the results. In this article, we have put together various processes of 3D printing a figurine, the technologies involved and finally a link to get yourself a 3D Printed Figurine. To begin with here are the two processes involved in the making of the figurines,
First: The Process of creating a 3D File, 3D scanning or 3D modeling from 2D Images
A full body 3D scanning is generally used to capture the photo data of the client. However, 3D scanning may not completely be able to capture the contours and shiny objects resulting in inconsistent results. This is one major reasons why experts like us rely on building the 3D model from scratch. Once a 2D picture is received, the data will be analyzed by the 3D designer. It requires a lot of manual design job to fix the files before it can be 3D printed. Different 3D softwares are used to bring out the organic design and to fill in the missing texture. 3D Figurine making is an Art.
Second: The Process of 3D Printing a Figurine
Color jet printing or multi jet printing is mostly used to 3D print figurines. The models are 3D printed using a gypsum based sandstone powder. Firstly, the main print head will jet the binding agents and the second print head jets the colored ink. Inks with different colors are usually combined to produce different rays of colors. After 3D printing, the model are coated with an infiltrant material to increase the strength and also bring out the vibrancy of the colors. Furthermore a technique called epoxy layering can also be done by a skilled team to improve the color appearance of the 3D printed model.
Why it is important to use the right 3D printers to make 3D figurines,
At Proto21, we have the best multi-color 3D printer the Projet 660 pro from 3D Systems
for a full color industrial 3D printing of photorealistic objects. The Projet 660 pro has many advantages making it one of the best full color 3D printer ideal for 3D printing figurines. There are many reasons why we use the Projet 660 to print our figurines,
firstly, high quality prints, the CJP Projet 660 pro provides a very high resolution full color 3D printing specifically for figurines. Secondly, the Industry reference, It is no doubt that CJP Projet 660 is one of the best choices for many 3D printing companies when it comes to having an in-house all-in-one 3D figurine solution. And lastly, it has one of the largest print volume of (254 × 381 × 203 mm) for a full color 3D printer, big enough to print large 3D figurines or individual portraits.

Supercars have always been inspired by unique concepts, Ferrari has a black prancing horse as their logo, Lamborghini’s bull logo shows their founder’s extreme interest in Spanish bullfighting sport, similarly the two flying wings in Bentley, Jaguar’s roaring face of a Jaguar and dodge ram are all unique concept designed with passion and vision.
Similarly, the ‘Drakuma’ is a Hypercar concept design by the CEO of Ajlani Motors, Bashar Ajlani with a long held vision to become the next Pagani. After 5 years of crafting, the Drakuma hypercar was finally unveiled at the Dubai Motor Show in 2019. According to statements, this model unveiled at the show is only a full-size mock-up but the company will be moving to production in the future with a 1200 horsepower engine and V8 Biturbo engine. Still being in the concept phase, the hypercar is believed to have two seats and carbon fiber body with the doors of the drakuma opening like a dragon’s wing.
While drakuma car certainly stole the show, a gorgeous 3D printed sculpture of a dragon enriched the event by attracting visitors. This state of art of the dragon model is 3D printed by Proto21 after being approached by Bashar Ajlani on understanding our capabilities and entrusting us with a huge part of his dream project. A few other parts of the drakuma car like the left and right design parts of the car were also 3D printed by us. It also completes Proto21 goal not to compromising when it comes to quality.
As seen, the 3D printed model shows a dragon emerging from the egg which is the logo and inspiration for the Ajlani Drakuma Supercar. The entire model was 3D printed as various parts using different 3D printing technologies like the most advanced HP MJF technology and SLA technology. The 3D printed parts were carefully put together and later finished with paint job complete the dragon model. The Painting job was done by our highly experienced and skilled team using top quality European imported paint to achieve the final look and mirror finish.
The Drakuma project is a huge example of the capacity of Proto21 as a 3D printing company to become a part of the clients’ requirement and bring together different technologies like 3D Printing, model making, chrome paining and other high quality finishing services to combine all the aesthetic and functional part of the design.
The use of transparent models in 3D printing is increasingly becoming an in-demand option for various industries and a wide range of customised projects using 3D printing in Dubai and across the region. Some of the top sectors that make good use of transparent 3D printing services are bottle manufacturers, jewelers and engineers who use the material to demonstrate their concepts with more details and with internal views.
Transparent 3D models and textures are made by solidifying liquid resin with ultraviolet light. A skillful understanding of the right techniques and process to use is required to ensure the right level of transparency and finish are achieved.
Solid training and experience with the material have equipped Proto21 with the level of mastery needed for 3D printing clear resin. Our team can provide 90 percent clear, transparent 3D prints. The printing layer height of this material can go up to 25 microns (0.025mm), providing high-quality results like any injection molded manufactured model. Minimum details can be 0.5mm with a clearance of 0.3mm.
Important Notes on 3D Printing Transparent Resin
Color Changes Over Time: Due to the nature of the technology, resin 3D prints solidified with UV tend to change color over time depending on the light environment.
Tinge: The tinge of transparent resin models may vary slightly. The greater the thickness of the model, the more noticeable the bluish tinge becomes. The tinge color is usually blue when we bring out a model from the printer. When we apply our technical finish to bring out more clarity, it gets yellowish. But the model gets clearer within 2 to 3 days of storage in an indoor or enclosed environment.
Technical Finish: Post-processing of clear 3D printing material at Proto21 is a long, labor-intensive process. A model can take more than one day for just post-processing. The complete lead time for a standard model with a size of 10cm x 10cm can take up to two working days.
Visibility: The visibility of the layers strongly depends on the shape or the design of the model. For instance, on a curved surface, layers will be much more visible. A special coat of chemical is applied to your model in order to make it transparent. This coat also protects your model from dust and helps minimize the discoloration process.
Every year, as the technology improves and expands, more and more 3D printing materials are introduced to the market. With so many options, it can be overwhelming to know which ones are worth utilizing and which ones are just a fad. Additionally, it can become even more challenging to know in which circumstances or for which products each material is best suited.
To help you make a well-informed decision, we have put together a list of the four most exciting 3D printing materials in 2020. Keep reading to learn more.
For a long time, plastics have been the most commonly used material for 3D printing as they provide a wide variety of options with different specs that can be utilized for different purposes. That being said, PLA and ABS are two of the most popular plastics for many product development applications.
Polylactic acid (PLA)is derived from plant starches – which makes it one of the most affordable options – and is known for its ease of usage, ability to print excellent details, and its strong form. Additionally, PLA comes in an extensive rainbow of colors, which makes it ideal if you want 3D printing that has high visual appeal.
The advantages of acrylonitrile, butadiene, and styrene (ABS) include its ability to create functional prototypes, and its high mechanical strengths and high thermal resistance. Its durability and toughness are among the main reasons industries worldwide opt to use this material for their 3D printing needs.
2. Polyamide (Nylon)
Slightly more expensive than plastic, polyamide is an exciting material for professional 3D printing services due to its superior flexibility and strength.
Its strong bonding quality makes it ideal for parts that require mechanical strength. Because of its rough surface that can be developed in many ways (colored, polished, spray-painted, velvet glazed), polyamide tends to be the first choice for many fields including engineering and architecture, medicine, and in the arts (e.g., sculpture).
As this material works with FDM and SLS technologies, at Proto21, we believe it performs its best when applied to concept models, functional models, medical applications, tooling, and visual arts. Other advantages include the fact that it is chemical resistant, food safe, and has high thermal properties and low moisture absorption.
3. Sandstone (Full Color)
If you require a multicolored object, then you are going to be excited to hear about sandstone, which is the ultimate full-color 3D printing material.
Often used to create figurines, avatars, or to showcase models, sandstone 3D printing is achieved by adding one layer of color at a time. At Proto21, once the model has been printed, we finish it with cyanoacrylate (super glue) sealant to guarantee durability and to sustain the vivid colors.
For many people, having a 3D printed sandstone model on their desk is the most significant benefit of this material; however, there are other advantages as well such as the affordable pricing and fast turnaround time.
That being said, it is crucial to understand that this material is not suited for producing functional parts or daily handling; else, the colors will quickly fade.
One of the best choices for functional and concept models, resin is especially suited for the manufacture of large parts within a shorter period of time, while preserving a tremendous amount of detail.
As a photopolymer, the resin begins as a viscous liquid that is then turned into a solid by exposing it to UV light.
There are a number of different resins available, all of which are used for different applications. At Proto21, we offer six types of resin for 3D printing and rapid prototyping:
Standard Grey Resin: Standard grey resin (SLA) is a high-detail resin that constructs components with a silky surface finish. Due to its fragile nature, this type of resin is best used for non-functional parts.
Dental Resin: Dental resins (SLA) produce highly-accurate, sterilizable, and biocompatible pieces that are used to create dental implants.
Castable Resin: Castable resin (SLA) is a high-detail resin utilized when producing patterns for investment casting as it burns out cleanly with minimal ash or residue.
Tough Resin: The ultimate choice when prototyping strong functional parts that can endure stress, tough resin even comes in a brilliant transparent turquoise color.
Durable Resin: For products or parts that have high wear and tear, the best choice is durable resin as its high elongation and high impact strength with excellent resistance from deformation ensure that it can survive the toughest conditions. Parts printed on durable resin have smooth glossy finishes, too.
Flexible Resin: The pieces created with flexible resin can twist and contract, making this material ideal for wearable models, such as handles, catches, and packaging.

It also creates elegance and adds strength to the 3D printed parts. Chrome or Chromium finish is a metal finish which increases the aesthetic appearance of a 3D model and keeping the parts protected from rust or erosion.
Chrome Painting is a complicated job and requires paint booths with right equipment, correct temperature setting and experienced professionals to handle every step of the process. And here at Proto21, we have the capacity and experience to do as many as number of Chrome paint jobs from small to big size in-house. We are known for our chrome paint jobs in Dubai and our portfolio speaks for itself. We offer chrome painting as an artistic element in different colors as per our client requirement bringing out the uniqueness in each 3D printed parts.
What is the Procedure
To apply chrome finishing, there are different techniques like spray cans, spray guns or air brushes depending on the surfaces but chrome painting is more of detailing than a regular painting job. The initial process is cleaning and priming, followed by several base coats. The painting itself can even be done in various steps, by adding one layer at a time, wait for it to dry and then decide to add another. The parts are then carefully washed with distilled water to remove dust particles and placed in a clean temperature controlled environment that is free of any dust.
Why Chrome finish is important for your business
Chrome finishing is known to add an artistic element to your 3D printed parts but also makes it a marketing tool especially when you are engaged in industries like manufacturing or art. It is also going to attract a huge number of users looking for a unique touch to their parts. Being able to finish and produce parts in chrome painting is very desirable especially for sectors like automotive, aviation and aerospace. Proto21 3D Printing ensures that you have the freedom and options to bring your ideas and concepts into reality within a short period of time but in the most effective way.

At Proto21, we have been successful in accomplishing many prestigious projects in no time especially complex models and functional parts that needs to be 3D printed and delivered in few days in the most cost-effective ways using HP MJG technology along with reverse engineering. As we enter industry 4.0, many business is going through a massive transformation and are looking for innovative solutions to expand their freedom of manufacturing flexibility for batch production and that is where the full potential of MJF technology will be used.
What is Multi Jet Fusion (MJF) technology?
Multi Jet Fusion is a powder based 3D printing technology which offers much more possibilities in digital manufacturing for complex and low cost parts. It uses a fine-grained PA12 powder material that allows for ultra-thin layers of 80 microns.
HP Multi Jet Fusion technology gives the freedom to iterate and test various designs and create faster, cheaper, and more lightweight products like gauges, models, sports performance eyewear, helmets, and trophies.
Below are samples of the fresh test prints with the HP MJF 4200 in Proto21.
The PA12 is a strong thermoplastic material well-suited for high-volume functional prototyping and low-volume production applications. It also leads to an exceptionally smooth surface straight out of the printer, hence functional parts and complex thin structures, only need minimal post-production finishing. That means short lead times, ideal for functional prototypes and small series of end-parts.
Why does manufacturing industries prefer MJF over other 3D Printing technologies?
Produce faster and more affordable high quality parts with HP MJF.
Decrease the assembly time and streamline your production processes
Cost Reduction Produce strong, reliable and functional parts for your exact specification and smoothen your workflow. Optimize production cost with cost-efficient materials that provides optimal output and high reusability at a lower cost per part.
Quality Functional Parts
Thanks to the HP Multi Jet Fusion technology and materials which ensures your printed parts are right for the job – exact, custom, and built to applications
No Supports Required Multi Jet Fusion technology has the ability to create any unsupported shape with overhangs. As the underlying powder supports the parts, it doesn’t need any generated structures for printing
[social_warfare] Architecture is one of the most competitive industries today. Clients now have a vast variety of choices, making architects face tough competition. Architectural firms need to present their designs in the best possible manner to win a project.
They also need to constantly innovate their designs in order to be recognised and highlighted. To motivate and inspire their clients, architects need to present physical models that best communicate the idea by showcasing the depth, dimensions and textures of a potential project.
To meet such requirements, using 3D models and generating 3D information have become a standard among leading architects today. 3D printing in architecture has made it possible to develop an easy workflow that takes 3D information and convert it into physical models.
In the past, models were made by traditional methods using foam, acrylics and cardboard, which is much more labor-intensive for model-makers. The rise of 3D printing helped streamline the process. Once the 3D file is ready, you can get the 3D print of your design concept overnight.
3D Model-Making Services by Proto21:
Benefits of 3D Printing in the Architecture Industry:
Numerous architecture and model-making companies in Dubai have reaped the benefits of 3D printing for their model-making needs. The following are the major advantages of using 3D printing in architecture:
Cost Savings: Traditional model-making is tedious and labor-intensive, resulting in the need for high investments for a single model. On the other hand, 3D printing reduces model-making costs to more than 50% due to the automated process and low wastage of material.
Short Lead Times: Handmade models take weeks and at times months to develop. With 3D printing, model-making becomes simply an overnight job.
Quality of Detail: 3D printing provides cutting-edge precision and accuracy. Standard qualities start from 100 microns and go up to 26 microns of details.
Better Communication: Printed 3D design is a way to present your projects to your clients in an interactive and engaging way. Clients can visualize your designs better and understand your concept design immediately. Seeing is believing!
Design Freedom: The beauty of 3D printing is that complexity is not a limit in additive manufacturing. Any design that is imaginable is physically possible. This gives full freedom to architects and artists to design without considering manufacturing limitations.
Scalability: No project is too small or too big for the technology. You can create models that will fit all your needs, from cityscapes and commercial buildings to home interiors exteriors and landscape.
Easy Iterations: Easily re-edit, reuse and reprint the models.
Easy Multiple Copies: Once the design file is ready, we can make as many copies as required.
Just like how hand drawings evolved to digital prints, handmade models have evolved into 3D printed models and transformed the world of design and architecture for good. To know more ways 3D printing is transforming the world today, discover our 3D printing services.
Anything which can be designed in digital space cannot be necessarily 3D printed. To identify the possibilities, it’s important to understand the rules to 3D printing.
In any type of manufacturing, there are specific rules and limitations that dictate how you must design your product before manufacturing process. The same goes for 3D printing processes. Because of the design restrictions, printers need to follow a number of 3D printing design rules whether it is for prototyping or for manufacturing end-use products.
3D printing can be a bit confusing. There are numerous software, different materials, printers and printing technologies. So, it is clear that there is no one-size-fits-all approach. The limitations in 3D printing are related to the primary mechanics of additive manufacturing process.
3D printing is no different from other additive manufacturing processes. There are characteristics of hardware, software, temperature, and filament and many other factors that should be focused in detail while designing in order to transform your digital model into a 3D printed object.
In this article, we will be discussing critical design considerations for a designer to avoid any mistakes while turning a 3D model into a 3D object. That what are the elements that should be looked after while creating components and parts for 3D printing? Understanding of these elements and the 3D printer design guidelines of each process will help the designer to master the process and able to manufacture certain 3D objects through 3D printing.
Digital vs. Physical
When designing for 3D printing, is it essential to keep in mind the fact that your digital design will end up as a tangible physical object? As far as digital designing is concerned, there's no law of physics to abide by, and the prime example is the gravity.
As what the experts say: “You can design any 3D object in a digital designing environment, but there is no such possibility or guarantee that you can print anything as a physical object especially in 3D printing.”
Every 3D printing technology has their own set of limits for printing procedure. Every 3D printing engineer must keep in mind the following things in prior consideration when printing a digital 3D object into a physical 3D object:
1. Consider ‘overhangs’ before 3D printing
Every 3D printing procedure will deliberately go by end-to-end layering and designing. It is nearly impossible to draw the 3D material on thin air which is the main reason that every 3D layer of the object must use some underline or withstanding material as support before the 3D object will get printed.
Talking about overhangs, they are an area of the 3D model which might occur to support the object layer or may not support the object at all. Most of the 3D printers usually have a limit of an angle which they can adjust when printing the object without needing to help the 3D material until the allowed object anglegets exceed. The mere examples are FDM and SLA because these technologies can hold up the object angle for not more than 45 degrees only.
It is better to keep the angel degree limits in consideration when 3D printing an object to avoid overhangs.
2. Try to keep a balance of 'Wall thickness' during 3D printing
Wall thickness is the second most important thing to keep in mind when designing a 3D object for printing. Most of the 3D printing procedure mainly compose the precise features of the 3D object which might be thin up to a certain level when printing them into a physical object.
For the better results, it is wise always to check the wall thickness of your models. For The successful printing of a 3D model, it is suggested to keep the wall thickness more than 0.8 millimeters.
3. Make sure ‘Warping’ doesn’t happen when 3D printing
Sometimes the thing which mostly overlooked while designing a 3D object is the materials. The fact they are unnoticed can make a lot of physical modification in your 3D model such as:
They may get melt
They may get sintered
They may get scanned by a laser and solidified
The warping of the 3D objects may occur during printing due to the heating and cooling of the materials.
The warping is more likely to happen when printing on a broad or flat surface. To avoid the warping while 3D printing your model, you must use an adequate surface area in grip with the proper usage of machine calibration. It is recommended to use a more circular edge for your 3D models for printing than using large and flat surfaces.
4. Always make sure the 'Level of detail' are up to the mark
Whenever printing a 3D model with a sophisticated level of details, it is essential to keep in the mind what can be the required feature size which 3D printer might be able to print.
The primary link of the mechanism of your 3D printer of the required level of detail for 3D printing is with the competences of the selected height of your object layers.
The material you will use in your 3D printing will decide the impact of your final 3D model. So, always try to make sure you have an adequate level of details set when 3D printing a design into a physical object.
What is an overhang in 3d printing? They are geometric shapes in a 3D model that have no material underneath them making layer-based 3D printing challenging. Overhangs are areas of a model that are partially supported by the layer below or not supported at all. There is a limit on the angle in every printer can produce out of support material. Some personal 3D printers must print support structures below to avoid the overhangs from immediately collapsing during printing. Some overhangs are acceptable still you can often
safely 3D print overhangs with as much as a 45 degrees angle overhang without any issue. If you are increasing the angle from 45 to above, then you are in the state of trouble, which in this case means droopy filament strands.
Another thing to keep in mind when designing a part to be 3D printed is wall thickness. Wall thickness is the value that gives a 3D model strength and durability. Thin walls for larger surfaces can be crumbling by the printer just because it is unable to print it accurately. The thinner the wall is, the more fragile and disposed to damage and warping the model is. For the avoidance of getting damage figurine, setting up a thicker wall thickness will ensure resistance to the pressure you apply when removing support and processing the model after printing.
Level of Detail
When you are creating a 3D model with intricate details, it is important to keep in mind what is the minimum feature size each 3D printing process can produce. The minimum level of detail is connected to the capabilities and mechanics of each 3D printing process and to the selected layer height. The process and materials used will have an impact on the speed and cost of your print, so determining whether smaller details are critical to your model is an important design decision.
Horizontal Bridge Gap
Bridging is when we print a flat, horizontal part of the model midair. While using a support structure for such a role could be a solution, it often works to bridge the gap without using support. We will have to drag lines of plastic between already printed parts, in a way that the plastic won’t fall down when being printed.
Fused Deposition Modeling happens on a building platform. Since models will be “built in the air”, they should be affixed to the supporting platform to keep them from crumbling. This joining is indicated as the “support” and is required for any model built utilizing this innovation. While keeping the model set up, it additionally empowers the development of components that stand out. After the making of building procedure is finished, the help is physically expelled. If it’s not too much trouble take note of that your model may show noticeable confirmation of the removed support structures.
An escape hole is usually involved when creating an object with a hollowed-out center. A borehole diameter of 2mm is recommended these type of escape holes is required to remove unfused material from the interior, just leaving the printed object behind. A technique that saves on price, since less material is the result.
The minimum pin diameter is known to be 1 millimeter. Even though smaller diameters are possible, 1 mm is the advised diameter to be used as it helps in maintaining the contour shape of the object.
Connecting and Moving Parts
3D printing encloses a wide range of technologies. Some more than others are particularly efficient to create complicated assemblies. However, as the technologies are evolving, we’ve reached a point where almost all of them can create part with moving components like a hinge or a joint. If we’re often looking at SLS 3D printing as the best solution for that, since we only need to remove the uninterred powder to “free” the moving parts, technologies like FDM or Polyjet have also brought solutions to add a “support material” that will be removed
with a solvent after the printing process. In any cases, regardless to the technologies you’re using, it’s now widely accepted that 3D printing technologies allow for integrated assemblies. Some with more facilities than other.
the tolerances and precisions of some 3D printing technologies are sufficient to create assembly that will simply “snap” together or will even be used for high performance goals. As a example, General Electric released a video showing how they successfully used additive manufacturing to create a fully working jet engine. The result is astonishing.With appropriate tolerances, parts with functional hinges, chain-link style textiles, and other types of moving components can be fabricated in a single print without the need for post-print assembly. This is one of the main upside of 3D printing when you want to manufacture a product since it can considerably reduce the number of necessary components to create your end product.
Rule of thumb
There are different 3D printing processes, but the basic rules and guidelines are more or less the same in each process and vary depending on the material and type of 3D printing process being used. DfAM (Design for Additive Manufacturing) is a big umbrella which includes all the rules, considerations and parameters needed in additive manufacturing processes.
3D printing technology is advancing rapidly,and there are demand and need of designing and making more intricate, elaborate and workable objects. There are specific procedures which are necessary when making a physical object and similar guidelines are mentioned in the DfAM ‘Rule of Thumb’. These rules are fundamental when designing and implementing your 3D model.
The 3D models to be designed must firstly fit the 3D printer build volume and either lie flat on the build plate or be supported. Support is one of the most keys, and critical part of the metal printing process and the measurements, placement, and geometry should be correct to prevent waste of materials, printing time and cost. The alignment and positioning must consider during the design stages as upward facing surfaces have sharper edges and a better surface finish.
The process and materials used will affect the speed and cost of your 3D print, so it is better to determine the smaller details which are critical to your design. One should avoid large flat surfaces and round the corners to prevent warping. Determine the minimum level of detail your 3D model require and choose the 3D printing process accordingly.
