Stereolithography (SLA) Prototype

SLA is a rapid prototyping process that is perfect for quick, highly accurate and detailed parts for presentation models, investment castings, and master patterns.

If high precision and smooth finish is your top priority we recommend having your parts printed on one of our SLA printers. SLA is a good choice for creating parts that are at an early stage of development and may require modifications before moving on to a higher cost stage of the production process.

SLA prototypes have many benefits, including high-temperature resistance, a high level of feature complexity, excellent surface finish, and the capacity to simulate a range of materials.

Applications

  • Pre-production applications
  • Concept models
  • Investment castings
  • Master patterns
  • Visual prototypes for photo shoots or checking 3D drawings
  • Prototypes for limited functional testing
  • Masters for copying techniques for vacuum casting
  • Representative parts of visual testing

Materials

  • The range of materials that can be used allows for a range of tolerances and property resilience. Material simulations include:
  • Polypropylene
  • PC
  • High temperature, high durability plastic
  • ABS

Properties

  • High-temperature resistance
  • Moisture resistant
  • Clear, white, translucent or colour finishing
  • High level of feature complexity
  • Excellent surface finish
  • Range of model sizes
  • Lathing and drilling options

Process

  • Stereolithography (SLA) prototyping is a rapid, 3D printing process
  • Parts are built layer-by-layer using a UV laser to solidify liquid photopolymer resins

Advantages

  • Rapid prototyping process; SLA models can be turned around overnight
  • Specific requirements: parts can be produced with high level detail and a smooth surface quality
