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

  • Black

  • White

  • Grey

  • Tough for Impact Resistance.

  • Flexible

  • Durable

  • High Temp

 

Other materials are available upon request.

 

Standard Resins Include:

Clear

  Polishes to near optical transparency.

  Ideal for working with light and showcasing internal details.

Grey

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

White

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

Black

  Formulated for models with very small features or intricate details.

 

Specialty Resins Include:

Tough

  Tough 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

 

Flexible

  Flexible 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

  • Wearables prototyping

  • Packaging

  • Stamps

 

Durable

  Durable was designed to simulate polypropylene (PP) 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
