STEREOLITHOGRAPHY (SLA)

This process offers quick prototyping capabilities with exceptional quality, good accuracy and nice surface finish, using UV laser as a source for curing liquid photopolymer. Widely used in jewelry, dentistry, casting and other applications.

Application
  • Master copies for vacuum casting and other low volume prototyping techniques
  • Patterns for investment casting
  • Functional testing prototypes
  • Low volume/ limited edition products especially for complex geometries
  • Dental/ jewelry/ art and other sectors which require high detailing and finish
Materials
  • Acura 25
  • Acura 60
  • Visijet tough
  • Visije clear
  • Visijet white
Design Guidelines
  • Min wall thickness: 0.8 mm
    (<0.7mm thickness areas may have some issues)
  • Min clearance: 0.3 mm
    (for Interlocking parts to aid fitment)
  • Min Details : 2.5 mm (text/ hole dia..)
  • Max size: 650 x 650 x 450 mm (Larger parts done in parts and fitted/ glued)
Output Details
  • Smooth, with tiny visible layers
  • Accuracy: ± 0.2% (with lower limit on ± 0.2 mm)
  • Layer thickness: 0.1mm
Post Processing
  • Support Removal
  • Curing
  • Smoothing
  • Primer
  • Coating/ Painting
Other Details
  • Lead Time: Depends on part (Min 2-4 days for dispatch. More for larger parts)
