The SLA process’ high accuracy, large variety of material selections, smooth surface finish, and wide variety of post processing options make it the perfect choice for a wide range of rapid manufacturing applications.
Stereolithography (SLA) utilizes a vat of liquid photopolymer resin cured by an Ultra Violet (UV) laser to solidify the pattern layer by layer to create a solid 3D model from customer supplied 3D data. The SLA process addresses the widest range of rapid manufacturing applications.
Highest accuracy and smoothest surface finish of all 3D printed parts
Large material selection – rigid, durable, clear and high-temp
Wide variety of post processing options
Prototypes for form and fit testing
Presentation models for displays and tradeshow models
Short lead times
High resolution settings
Large build platforms available
Tolerances for standard resolution:
X/Y planes: +/- .005” for the first inch, plus +/- .002” for every inch thereafter
Z plane: +/- .010” for the first inch, plus +/- .002” for every inch thereafter
Minimum linear feature size: under .030” are at risk and under .020” will not build
Minimum radial feature size: .035″
Tolerances for high resolution:
X/Y planes: +/- .005” for the first inch, plus +/- .002” for every inch thereafter
Z plane: +/- .010” for the first inch, plus +/- .002” for every inch thereafter
Minimum linear feature size: under .020” are at risk and under .010” will not build
Minimum radial feature size: .030″
3D Systems’ SLA printers are able to print highly detailed parts ranging from just a few millimeters in size, all the way up to 1.5 meters (5 ft), with exceptional resolution and accuracy and virtually no part shrinkage or warping
