These are the questions I am most frequently asked. The answers are the solutions that worked for me, but there may be better options out there.
If you have other questions that I should add to this list, please post them in the comments. 🙂
Why do my prints have bubbles or white stuff on them after they’re cured?
This is usually the result of uncured resin being left on the print. Resin likes to rest in the cracks and crevices of your models, so using a very soft toothbrush will help tremendously. Also, if you’re using water washable resin, be sure your print is completely dry before you place it in the curing station.
Why don’t my multi-part prints fit together?
Most likely, your print shifted a bit while printing. In my experience, this is caused by a lack of support in areas where the model might shift ever so slightly while lifting off the screen. Ensure the entire model is as evenly supported as possible – even if it means adding seemingly unnecessary supports to some areas. Better to clean up a few more support dimples than try to force pieces to fit.
Is resin food and/or aquarium safe?
In almost every case, the answer is no. There may be some types of resin that are food/aquarium safe, but I’m unaware of where to find them. A friend printed a bird whistle in resin and blowing it gave him a sore throat.
As far as aquarium safety, I tested in a small tank and found the water parameters were not suitable for fish. Total Dissolved Solids spiked into dangerous levels. I’ve heard some people have used resin prints in aquariums after giving them several coats of aquarium safe coating, but it’s not something I would risk.
What is the best way to repair a broken resin print?
In my experience, the best method is to use some of the uncured resin like glue. Just use a UV flashlight to cure the resin. If bits of the resin ooze out, just file them down to match the model. If done carefully, you won’t even be able to tell it was broken.
I recommend – Escolite UV Flashlight
