What is Resin 3D Printing?
Resin 3D printing (commonly SLA or DLP) uses UV light to cure liquid photopolymer resin layer-by-layer. Compared with filament printing, resin printing is known for high feature detail, smooth surfaces, and fine geometry, making it ideal for functional prototypes and presentation-quality parts.
Key Benefits
- High resolution & fine features (sharp edges, small text, micro details)
- Smooth surface finish with minimal layer lines
- Complex geometry including thin walls and internal features (design-dependent)
- Material options for different performance needs (tough, high-temp, flexible, clear)
- Great for molds/masters and small-batch production parts
Typical Applications
- Engineering prototypes and enclosures
- Fixtures, jigs, and lab tooling
- Microfluidics and small channels (process-dependent)
- Medical and dental prototypes (non-clinical)
- Casting masters and silicone mold patterns
- Optical holders and alignment components
Material Options (Examples)
- Standard resin: general prototypes
- Tough resin: better impact resistance, snap-fit parts
- High-temperature resin: fixtures near heat sources
- Flexible resin: compliant parts, gaskets, vibration damping
- Clear resin: visualization/light guides (polishing/coating recommended for high clarity)
If you tell us your operating temperature, load, and environment, we can recommend a suitable resin type.
Post-Processing (Options)
- Wash + UV cure (standard)
- Support removal + light finishing
- Sanding / polishing (especially for clear parts)
- Dye/paint/coating (project dependent)
- Threading, inserts, and light assembly (optional
