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.
