Stereolithography (SLA)

Stereolithography, or SLA, manufactures high-resolution 3D printed plastic products in relatively large sizes by selectively curing a light-sensitive resin within a tank. It is a great solution for quickly creating inexpensive aesthetic models and casting patterns with a smooth finish.

SLA is compatible with a range of materials which come in clear, translucent and opaque finishes. These materials are able to mimic many of the properties of ABS, polycarbonate and polypropylene.

3D printed plastics are durable, inexpensive and quick to produce. They also eliminate many of the design restrictions of traditional manufacturing. To learn more about our other 3D printed plastic options, check out our HP Multi Jet Fusion 3D printing services or our 5-Minute Buyer’s Guide.
