stereolithography (SLA)

We acquired a series of FormLabs printers for prototyping in our own development efforts. We currently have the latest From 2 system and can use any of the many resins Formlabs offers for specific needs.  we are upgrading to the new Form 3 printers (the Form 3 and Form 3L) which provide larger print volumes and higher resolution and accuracy than the From 2 system.   The Form 3 should be available by July 2019 and the From 3L by Q4 2019.  These printers offer xy resolution of 25 microns, layer thickness options of 25, 50, 100, 200, or 300 microns.   The result is an exceptional quality of print.

We offer pricing from STL customer supplied STL files as well as complete CAD design services as fits the customer needs.

You can learn more about SLA and the From2 system we use at the FromLabs web site.

Resins available:

Standard Resins

Clear: Transparency, polishes to near optical clarity, great for internal channels and working with light.

Black: Highly pigmented, our most opaque, high detail resin. Matte surfaces, great for printing small, intricate features.

White: Neutral and matte tone, slight translucency when thin. Works well for sanding, and provides a great base color for painting prints.

Grey: Neutral and matte tone, great for showing off surface finish and for printing small, accurate features, photographs easily.

Draft: Draft Resin is suitable for printing large, bulky parts quickly. With a 300 micron layer height, it has acceptable accuracy for prototyping needs while enabling faster design iterations.

Color:  Print parts in color without painting with Formlabs Color Resin. Formlabs supports 16 colors and suggests recipes for other colors combining CMYKW pigments.

Engineering Resins

Grey Pro: offers high precision, moderate elongation, and low creep.  This material is great for concept modeling and functional prototyping, especially for parts that will be handled repeatedly.

Rigid:  Rigid Resin is reinforced with glass to offer very high stiffness and a polished finish. This material is highly resistant to deformation over time and is great for printing thin walls and features.

Flexible: Simulates an 80A durometer rubber. Choose for impact resistance and compression, great for ergonomic soft-touch grips.

Tough: Simulates ABS plastic. Choose for applications that will undergo high stress and strain. Great for functional prototyping of assemblies, machining, snap-fits and living hinges.

Elastic:  50A Shore durometer material is suitable for prototyping parts normally produced with silicone. Choose Elastic Resin for parts that will bend, stretch, compress, and hold up to repeated cycles without tearing.

High Temp: Has an HDT of 289 °C @ 0.45 MPa. Choose for static applications that will experience high temperatures, including moldmaking processes such as thermoforming, vulcanization, and electronics encapsulation.

Durable: Use to prototype models that will eventually be made from polypropylene (PP) or high density polyethylene (HDPE). Consider using where high elongation, deformation, and/or impact resistance are required.


Castable: Developed for clean burn out and high detail. Choose for direct investment casting, resin is blue in color, and slightly softer than standard resins before post-curing.


Ceramic Resin is a silica-filled photopolymer. After firing, the photopolymer network burns out to form a true ceramic part. Fired parts have unique properties that can be leveraged for applications where fired part accuracy is not critical.
