SLA / DLP

detail, dialled in

Stereolithography and Digital Light Processing. UV light cures liquid resin, layer by layer, producing the finest detail and smoothest surface finish of any 3D printing process. Near injection-mould quality, straight off the printer.

01 Why use it the good bits
  • Surface finish like nothing else: near injection-mould quality off the printer.
  • Feature resolution down to 25–50 microns: sharp edges, embossed text, micro features.
  • Optical clarity via polished clear resins: light pipes, lenses, fluidics.
  • Widest resin library in 3D printing: engineering, flexible, high-temp, biocompatible, castable.
  • The go-to for master patterns feeding vacuum casting, investment casting, silicone moulding.
  • Overnight builds on large-format SLAs; parts in your hand within 24 to 48 hours.
02 Ideal volumes how many?
  • 1–100 parts: concept models, design verification, marketing samples, trade-show prints.
  • Best for aesthetic and form-fit prototypes; visual models for design reviews.
  • Master patterns for vacuum casting (10 to 30 copies per master).
  • Production: dental aligners, jewellery masters, hearing aids, microfluidics.
