A resin print is not finished when the build plate stops moving. Between the printer and the final part sit two critical steps: washing and support removal. Done wrong, they can scratch, warp, or snap an otherwise perfect print.
Why Washing Matters
Fresh resin prints are coated in a thin layer of uncured resin. If you skip washing, that residue cures into a sticky, glossy mess that ruins surface detail. Washing removes the uncured resin before final curing, and the choice of solvent matters a lot.
IPA vs. Resin Detergent
Isopropyl alcohol (IPA) is the classic choice, but it is flammable, evaporates quickly, and needs frequent replacement. A dedicated cleaner like the ANTINSKY Resin Detergent offers a safer, non-flammable alternative that lasts longer and cleans just as effectively. Either way, agitate the part gently in the solvent rather than soaking it too long, which can soften thin walls.
Support Removal Technique
- Remove supports before final curing, the resin is still soft and easier to work with
- Cut close to the part with flush cutters rather than twisting or pulling
- For fine details, use a hobby knife and work slowly
- Warm water can soften supports slightly, making them easier to remove cleanly
Choosing the Right Resin
The Standard Lite Resin flows easily and releases supports cleanly, making it a good choice for detailed models. The Standard Resin offers a solid balance for everyday prints, while the Standard Tough Resin is better for functional parts that need to survive support removal without cracking.
Wash carefully, remove supports patiently, and your resin prints will come out clean and crisp.
