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)
