Stereolithography (SLA) is the first choice for producing complex geometries with excellent accuracy and great surface finish. InterPRO operates nine SLA high resolution and large frame SLA systems in-house.

InterPRO’s unique SLA Nano technology quickly produces very small or very large prototypes with incredible accuracy, utilizing a variable-diameter laser beam that focuses to 0.004” diameter for high precise features. InterPRO offers many SLA materials to choose from, including glass clear, high impact strength, high HTD and Class VI medical grade.

Benefits


  • Extremely accurate with very high resolution
  • Properties closely mimic thermoplastic
  • Excellent surface finish
  • Easy to add paint, nickel/chrome plating, EMI shielding, inserts, custom textures and graphics
  • Very fast delivery available

Applications


SLA is the best 3D printing technology for producing ultra- clear lenses and bottles. The strength and detail of SLA
models make them the best choice for design verification models, fit check models, appearance models, large housings
and master patterns for RTV molding.

SLA patterns are great for

  • Metal casting patterns
  • Thermoforming molds
  • Fixtures for assembly.
  • Flow testing and visualization
  • Functional testing
  • Wind tunnel models

Process


SLA works by focusing a UV laser onto a vat of photo curable resin. As the laser draws a shape on the surface of the photopolymer, the resin is solidified and forms a single layer of the desired 3D object. The process is repeated for each layer of the design until the 3D object is complete

Standard build layer height is 0.004″
High resolution build layer height of 0.002″ is also available.
