SLA

Stereolithography is an additive fabrication process that uses a laser to build up a 3D object, layer by layer, in a vat of liquid photopolymer.

A resin that hardens when touched by UV rays rapidly transforms into high-precision components for design validation or presentation models.

Ideal for:

  • Large parts
  • Aesthetic prototypes
  • Formal validation and assembly
  • Small parts with fine details

Specifications

This process allows us to make the largest, most detailed parts imaginable. With the large number of printers and materials we have available, we’re able to quickly deliver many parts at once.

Materials

Three different resins, all of which are easily sanded and painted:

  • Accura 25: This resin simulates polypropylene. It’s flexible and lets you test snap-together assemblies.
  • Accura ClearVue: This rigid, transparent resin is perfect for making parts with high transparency.
  • Accura Xtreme White 200: This resin simulates ABS. It’s tough and durable so you can use it to check the functionality of your designs and assemblies.

Resolution

The resolution for SLA parts is between 0.002” and 0.004” per layer. A part’s geometry, wall thickness, and orientation during construction can all impact tolerancing.
Make sure to tell us which dimensions are the most critical.

SLS

Selective Laser Sintering or SLS is an additive fabrication method that makes 3D objects from powdered materials. A laser is used to heat and fuse the powder layer by layer.

This technology creates functional prototype parts that are well-suited for use in tough environments and demanding applications.

Ideal for:

  • Mechanical validation
  • Functional prototypes and production parts
  • Complex geometries

Specifications

The dimensions of the available vat are 13” x 11” x 17” for basic nylon (PA). As with most additive technologies, larger parts can be built in sections and assembled afterwards.

Materials

Three white polyamide 12 powder-based resins:

  • PA 2200: This resin is durable, rigid and chemical-resistant.
  • PA 3200 GF (glass beads): This resin is defined by excellent rigidity and good elongation at break thanks to the glass beads added to the resin. It also has a good thermal load capacity and resistance to wear.
  • PA 2210 FR (UL 94 V-0): This resin includes a UL 94 V-0 classed flame retardant. It also has good mechanical properties.

Resolution

The resolution for SLS parts is between 0.004” and 0.006” per layer. Part geometry, wall thickness, and orientation during construction can all impact tolerancing. Make sure to tell us which dimensions are the most critical.

MJF

Multi Jet Fusion uses a printhead to selectively apply fusing agents and details on a bed of nylon powder which is then melted by heating elements to the previous layer. The process continues until the piece is complete.

Ideal for:

  • Mechanical validation
  • Functional prototypes and production parts
  • Complex geometries

Specifications

The dimensions of the available vat are 15” x 11.2” x 15” for basic nylon (PA). As with most additive technologies, larger parts can be built in sections and assembled afterwards.

Materials

The nylon 12-based resin available is PA 12.

  • PA 12: This resin offers excellent mechanical properties and is waterproof.

Resolution

The resolution for MJF parts is 0.003” per layer. Part geometry, wall thickness, and orientation during construction can all impact tolerancing. Make sure to tell us which dimensions are the most critical.

FDM

Fused deposition modeling (FDM), also known as fused filament fabrication (FFF) technology extrudes a filament of thermoplastic material along a path defined by the construction file. It often requires support structures which can be broken off once the piece is built.

Ideal for:

  • Large parts
  • Mechanical validation

Benefits:

  • Wide variety of materials

Specifications

The maximum size available for construction is 14'' x 10'' x 10''. As with most additive technologies, larger parts can be built in sections and assembled afterwards.

Materials

Several resins are available:

  • Ultem 1010: This thermoplastic resin offers excellent durability and thermal stability.
  • Ultem 9085: This resin has a high strength-to-weight ratio and good heat resistance.
  • ABS M30: This resin is stronger than standard ABS and is available in a wide variety of colours.
  • PC ABS: This resin is a mix of PC and ABS with high durability and heat resistance.

Resolution

The resolution for FDM parts is between 0.010” and 0.013” per layer. Part geometry, wall thickness, and orientation during construction can all impact tolerancing. Make sure to tell us which dimensions are the most critical.
