3D Printing/StereoLithography

Accurate professional 3D printed parts directly from 3D CAD data in a matter of hours without drawings, tooling, or machining.



3D Printed Parts StereoLithography Aparatus


protoCAD 3D prints both Polypropylene like and ABS like materials utilyzing StereoLithography.

Painted 3D Printed StereoLithography

The 3D printed parts are naturally amber in color.  We can paint or dye the parts.  Polished parts are transparent with an amber tint.



Helicoils Installed 3D Printed StereoLithography


protoCAD assembles Helicoils into the 3D printed parts for threaded features.  Threaded inserts can be adhered in place and large threads can be just 3D printed.

Large 3D Printed StereoLithography

protoCAD can 3D print parts up to 20"X20"X24" in a single build. Parts as large as 4'X3'X1' have been printed by breaking the part into multiple pieces then assembling them after they have been printed.

Rapid Delivery



Most parts are delivered in 2-3 business days depending on the size and volume of the part(s).

Large Quantity 3D Printed StereoLithography 

Quantities range from a single part that might be used for a design evaluation to thousands of parts that are used as production parts.



Accurate 3D Printed StereoLithography

The 3D printed parts are very accurate and are generally within +/-.005" with an additional +/-.001 in/in.  We work with our customers to ensure critical tolerances are achieved.

Finiash 3D Printed StereoLithography

protoCAD delivers the 3D parts with a bead blast finish.  The parts can also be provided without a finish, a polished finished.  We work with the customer to provide any specialty finish they may desire.

Armor Coating

Master Patterns

Armor Coated 3D Printed StereoLithography

StereoLithography and Urethane Castings can be strengthened and hardened or electronically shielded using a thin coating of copper and nickel to form armor coating. Armor coating can be applied to entire part or selected part surfaces.

Master 3D Printed StereoLithography Urethane Casting Prototype RTV Rubber Mold

3D printed StereoLithography parts are ideal for Urethane Casting master patterns as they are very accurate and have a beautiful surface finish. 


3D Printed StereoLithography Process Sliced

A CAD file is digitally sliced into horizontal cross-sections. A laser traces a cross-section onto the surface of a bath of photopolymer solidifying the cross-section. The part is lowered into the bath and resin is swept onto the surface. The laser then solidifies the next cross-section. This process is repeated until complete.
