Resin 3D printing delivers unmatched detail, but the raw print straight off the build plate isn't ready for display. Proper post-processing is where the magic happens.

Step-by-Step Post-Processing:

  • 1. Washing: Submerge your print in isopropyl alcohol (IPA) or a dedicated washing station for 5 to 10 minutes to remove excess uncured resin.

  • 2. Support Removal: It is often easier to clip supports before UV curing while the resin is slightly softer, or dip the model in warm water to make supports snap off cleanly.

  • 3. UV Curing: Place the clean model under a UV curing station or sunlight for 3 to 5 minutes until the surface is completely non-tacky.

  • 4. Sanding & Priming: Smooth out any remaining support marks using fine-grit sandpaper, then apply a layer of primer before painting.

Follow these steps carefully to ensure your resin models are durable, safe to handle, and look professionally crafted.
