Overview
Our SLA/MSLA resin printing delivers layer resolutions as fine as 0.025 mm - 4–8× finer than FDM. This makes it the material of choice for jewellery casting masters, dental models, miniatures, and any part where surface finish and dimensional accuracy are paramount.
After printing, parts are post-cured under UV light to achieve full mechanical properties.

Advantages & Limitations
Advantages
- ✓Extreme detail reproduction - fine threads, text, and organic curves
- ✓Near-injection-moulded surface finish out of the printer
- ✓Isotropic strength (same in all directions)
- ✓Watertight without post-processing
Limitations
- ✗More brittle than FDM materials - not suited to functional snap-fits
- ✗Requires post-curing; uncured resin is a skin irritant
- ✗Higher cost per unit volume than FDM
Applications
Jewellery casting mastersDental modelsFigurines & miniaturesMedical surgical guidesMicro-featuresHigh-fidelity architectural models
Printing Tips
Resin parts are washed in IPA immediately after printing, then fully post-cured under a 405 nm UV lamp for 2–5 minutes per side. Avoid over-curing which causes brittleness. We handle all post-processing - you receive a fully cured, clean part.
Frequently Asked Questions
Can resin parts be painted or sanded?
Yes - fully cured resin accepts primer, acrylic, and enamel paints very well. It can also be sanded with fine grit sandpaper to remove any remaining layer lines (typically already minimal).
