3D Printing – Stereolithography (SLA)
About the project
SLA represents one of oldest and most mature 3D printing techniques nowadays. High surface quality and high accuracy are just the most remarkable key features. Briefly, a UV source (e.g. a laser) is used to selectively “write” a pattern into a photo-active polymer resin. When the pattern is completed, a new layer of resin is added, followed by writing the next pattern. This is continued until the object is printed completely. Large size parts can be printed with its limit in lifetime, mechanical strength, biocompatibility and color availability .
