Glue Parts and Repair Small Holes

Prints don't always come out perfectly. Parts that print with a few small holes can often be salvaged. Sometimes a part might become damaged or torn during the support removal process. The following tips will help you bring these prints back to life.

You will need:

  • a toothpick
  • Formlabs resin
  • the sun (or a 405 nm laser pointer)
  • 220 - 1500 sand paper

Follow these steps:

  1. Dip the toothpick in the resin and fill the hole completely. The more accurate you are now, the less sanding and finishing you will have to do later.
  2. Leave the part to cure in the sun or use a laser pointer to quickly cure the resin.
  3. When fully cured, sand the bumps until the surface is smooth.


You can also follow these steps to adhere two parts of a model that print separately.
