Printing with SLA gives you:
- Excellent surface detail and finish
- Materials designed to simulate real material
- Fast turn around on small parts
- Unique material properties like semi clear, and heat resistance up to 550F
In a stereolithography machine, the part is built upside down from UV curable photopolymer resin by a UV laser. When viewed as a time lapse, the parts seem to grow out of the resin bath. To support the printed part, the printer software generates support material that is removed once the print is finished.
SLA printers are excellent at producing fine detail that other printers cannot match. The wide variety of resins are great for prototyping because the cured resins have been designed to mimic real world materials.
