Stereolithography (SLA) is a precise, resin-based 3D printing technology that uses a UV laser to cure liquid photopolymer resin into solid, high-resolution, and intricate parts. SLA printing is an ideal technology for producing detailed models with smooth surface finishes, high strength, and accuracy.
We have two Formlabs Form 4 Resin printers and offer most of Formlabs Standard Resins
- High resolution and detail
- Smooth surface finish
- Wide range of material options (Discovery Lab Stocked Resins)
- Fully solid parts
- Biocompatible options available
- Higher material costs
- Greater processing costs
- Greater environmental impact
- Build Volume: 200 × 125 × 210 mm
- X-Y Resolution: 50 µm with pre-tuned anti-aliasing for subpixel resolution
- Z-Layer Thickness: 25–300 µm (depending on material and resolution settings)
- Smallest Feature: ~50 µm
- Technology: MSLA, 405 nm LFD (Low-Force Display)
- Dimensional Tolerance: 1-30 mm features: ±0.15% (lower limit: ±0.02 mm) 31-80 mm features: ±0.2% (lower limit: ±0.06 mm) 81-150 mm features: ±0.3% (lower limit: ±0.15 mm)
Available Materials: Total of 38 Formlabs materials, including 15 biocompatible, or third-party materials using Open Platform. New materials being developed periodically. See All Materials On-hand Materials: Black v5, White v5, Clear v5, and Flexible 80A
