SLA (Stereolithography)

Stereolithography is a rapid prototyping process which produces a physical, three-dimensional object from a 3D CAD file.  Stereolithography is commonly referred to as SLA, although SLA is really a Stereo Lithography Apparatus. A stereolithography apparatus uses a computer controlled laser to cure a liquid photo-curable resin, layer by layer, to create a 3D part.


Parts are created with excellent precision, with tolerances to 25 microns.


A variety of materials are available including:


  • Clear

  • Grey

  • White

  • Black

  • Draft

  • Tough/ Durable

  • Flexible / Elastic

  • High Temp


Other materials are available upon request.


Standard Resins Include:


  Polishes to near optical transparency.

  Ideal for working with light, mold making, optics & showcasing internal details.


  Perfect for general purpose prototyping and design, excellent for capturing small details.


  Perfect for smooth surface finish and details. Great for presentation ready pieces.


  Formulated for models with very small features or intricate details.


     Prefect for quick builds, iterative prototyping that does not require high detailed results.  Great for Initial Prototypes, Rapid Iterations & High Throughput.


Specialty Resins Include:

Tough 20 / 15:

  Tough 20 was designed to simulate ABS plastic, with comparable tensile strength and modulus. Perfect for functional prototyping, this sturdy, shatter-resistant material has been developed to withstand high stress and strain.

  • Snap-fit joints

  • Assemblies

  • Rugged prototypes


  Tough 15 is designed to produce stiff and pliable parts that are able to bend and spring back quickly to original shape.  Perfect for functional prototyping, this sturdy, shatter-resistant material has also been developed to withstand high stress & strain.

  • Snap fit & press fit connectors

  • Springy prototypes & assemblies

  • Designed to simulate Polypropylene (PP) in both strength & stiffness

Flexible & Elastic:

  Flexible 80A simulates an 80A durometer rubber. Use this versatile material to produce parts that need to bend and compress. Flexible is excellent for simulating soft-touch materials and adding ergonomic features to multi-material assemblies.

  • Handles, grips and overmolds

  • Cushioning and dampening

  • Seals, Gaskets & Masks

  • Packaging

  • Stamps


    Elastic 50A simulates a 50A durometer rubber. Use this versatile material to produce parts that would normally be produces with silicone.  Elastic is excellent for simulating parts that will bend, stretch, compress and hold up to repeated cycles without tearing & spring back to their original shape quickly.


  • Wearables, such as straps

  • Compressible buttons

  • Stretchable enclosures & casings

  • Soft tissue anatomy


  Durable was designed to simulate polyethylene (PE) plastic, with comparable low modulus and high-impact strength. Use this wear-resistant, ductile material when parts require deformation and a smooth, glossy finish.

  • Prototyping consumer products

  • Impact resistant cases

  • Low-friction and low-wear moving parts

  • Snap fits and ball joints


High Temp

  High Temp has an HDT of 289 °C (552 °F) @ 0.45 MPa—the highest on the 3D printing materials market. This material is great for static applications that will undergo higher temperatures. High Temp can also be used for production processes such as casting and thermoforming.

  • Mold prototyping

  • Heat resistant fixtures

  • Hot air and fluid flow

  • Environmental testing
