Good uses for resin
- Small parts with fine features, text, or thin details
- Cosmetic prototypes that need a smooth surface
- Master patterns for moulding and casting
- Miniatures and detailed models
Limits
- Standard resins are brittle; for clips or impact, ask about tough resin or choose nylon.
- Large parts are less economical in resin than filament.
- Standard resins yellow and weaken in sunlight.
Designing for resin
Hollow resin parts need drain holes so uncured resin can escape. Very thin walls may warp or break during cleaning. See the design guide for typical minimums.
Questions
What's the difference between resin and filament 3D printing?+
Resin (SLA/DLP-style) printing cures liquid resin with light and gives finer detail and smoother surfaces. Filament (FDM) printing extrudes melted plastic and offers tougher, more economical materials for larger functional parts.
Are resin prints strong?+
Standard resins are hard but brittle. Tough and engineering resins improve impact resistance. Describe the use and we will recommend a grade.
