Small details are part of what makes resin 3D prints look great, but they can also be easy to break. In this MakerBuildIt video, a Halloween witch miniature has lost part of its wand. Rather than starting with a new print, we repair the broken piece using a little liquid resin and a UV light.
We had already tried super glue on this particular break, and it did not work very well. The resin repair shown here gives us another way to reattach that small detail.
Watch the repair
What you need
- The resin print and its broken piece.
- A small amount of UV-curable printing resin.
- A UV curing light compatible with your resin. In the video, we use a handheld UV wand.
When handling uncured resin, wear protective gloves and eye protection and work in a well-ventilated area. Follow your resin and UV light manufacturer's handling instructions. See ELEGOO's resin handling guidance.
How we fix the broken wand
- Apply a little resin to the break. We put a small amount of resin on the broken area where the wand will reconnect.
- Align the pieces. Bring the broken piece back into position and keep the joint steady.
- Cure the joint with UV light. Aim the curing light at the resin around the join while keeping the pieces aligned. The added resin hardens and attaches the two pieces.
- Continue curing before checking the repair. In the demonstration, the piece attaches quickly, but we keep the light on it for roughly another 20–30 seconds. That is the timing described for this repair; follow the curing guidance for your own resin and light.
The result
At the end of the video, the broken wand is attached to the miniature again. It is a quick demonstration of using UV-curable resin to repair a small resin print.
This video shows one repair rather than a comparison of every adhesive or a long-term strength test. If you have a similar broken detail, watch the close-up demonstration above to see how we position the piece and cure the joint.
