Post-processing is where resin 3D prints go from "fresh off the plate" to professional results. This guide covers the essential workflow — washing, drying, and curing — with the latest tools and techniques.
Step 1: Washing — Remove Uncured Resin
By Inno Uncle
Options for cleaning your prints:
- IPA Wash — traditional method, 99% isopropyl alcohol, 3-5 minutes
- Resin Detergent — safer alternative, non-flammable, low odor, reusable
- Ultrasonic Cleaners — like the UniFormation W230, 40KHz for thorough cleaning
Step 2: Dry Completely Before Curing
Moisture trapped during curing causes white spots and surface defects. Let prints air-dry or use a heated dryer (45-50°C). The UniFormation Cure 3 Ultra combines both drying and curing in one unit.
Step 3: UV Curing
Standard 405nm UV curing takes 2-5 minutes. For best results:
- Use a turntable for even exposure
- Don't overcure — it can make parts brittle
- Engineering resins may need longer curing times
