Like SLS, uses a laser, however, not just sinters the powder grains but melts them together. Parts are recommended to be post-processed or coated as they are highly porous. This technology is most cost-efficient when many parts are nested and printed in one run. Using a laser fuses plastic powder grains layer by layer. Operates several nozzles to drop mix and combine UV resins with each layer instantly cured by the source on the printing head. With a more powerful and precise light source (projector in DLP and a laser in SLA) these technologies are more accurate and smooth. On the bright side, DUP printing is much quicker than common SLA. While similar to stereolithography, LED-based 3D printers are more prone to voxelization, resulting in parts with more visible layers. Uses LED lights and a masking screen to selectively cure UV resins. Produces objects from string plastic or rubber, which is heated and extruded through a nozzle to form an object from the bottom up. Produces metal parts and components, suitable for replacements and rapid metal prototypes. Works best for low batch productions, snap-fit prototypes and mechanical parts. Provides accurate structure, texture and visual appearance. High-definition resin printing with multiple materials and color support. High-precision resin printing for medical applications and jewelry master models. An affordable way to get rough prototypes, educational and hobby projects.īudget friendly printing with resins, great for figurines, minis and scale models.
