What is Stereolithography (SLA)?
  • A "rapid-prototyping" process which produces a physical, three dimensional object from a 3D CAD file.
  • Based on the principle of curing (hardening) a liquid photopolymer into a specific shape.

Surface Quality
    • roughness of the untreated surfaces of SLA components >103 better than FDM components.
  • Dimension Change with Humidity
    • permanent changes in the dimensions occur when SLA components stored under humid conditions.
benefits of sla
Crisp, highly-detailed pieces

Speed of delivery (usually 2-3 days)

Tolerances within .005"/inch

Save Money

Save Time

Test Product

Catch Errors

Improve Design

Sell Product

Rapid Manufacturing

Benefits of SLA
applications of sla technology
Applications of SLA Technology
  • Aesthetic & conceptual models
  • Parts requiring detail & accuracy
  • Master patterns for castings and secondary processes
conclusions
Conclusions
  • Stereolithography is fast and effective.
  • Stereolithography can be applied to almost every industry, including oil refining, petrochemical, power, marine, and municipal
  • Stereolithography saves time, money, allows speed delivery, and improve designs
