Stereo lithography (SLA)

Stereolithography (SLA) 3D printing uses a laser to cure solid isotropic parts from a liquid photopolymer resin. When the process starts, the laser “draws” the first layer of the print into the photosensitive resin. Wherever the laser hits, the liquid solidifies. The laser is directed to the appropriate coordinates by a computer-controlled mirror. At this point, it’s worth mentioning that most desktop SLA printers work upside-down. That is, the laser is pointed up to the build platform, which starts low and is incrementally raised. After the first layer, the platform is raised according to the layer thickness (typically about 0.1 mm) and the additional resin is allowed to flow below the already-printed portion. The laser then solidifies the next cross-section, and the process is repeated until the whole part is complete. The resin that is not touched by the laser remains in the vat and can be reused.

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

Speed

Due to the large number of print heads, the layers take only a few seconds to be printed and fused. The fusing process is integrated in the printing process, so there are no extra steps involved. All in all, Jet Fusion is many times faster than FDM or SLS 3D printing. More than 3 cm per hour can be printed which puts this process among the fastest additive technologies available today.
