What do I do if my ABS part isn’t sticking? Acetone ABS

Make sure that the PET film is facing up on your glass.  Use the Acetone-ABS mixture on your glass. The rule of thumb is to print until your part does not stick; then apply the mixture. Also, increasing the bed temperature slightly should help with the stick.  Below is the recipe for the acetone and ABS mixture.

Recipe for “Goo”:

  • 1/2 cup of acetone
  • 2 -3 inches of natural ABS (3 MM filament) OR a small printed ABS part

Acetone “Goo” is a great solution to problems with part stick. The Airwolf 3d printer comes with a great heated bed, that heats up entirely and evenly to minimize part curl up. We took it a step further- and covered the glass plate with PET film.
However, sometimes you want a part to have a smooth glossy ultra flat finish on its bottom (like the cover on the circuit board for your 3D printer). To achieve this, try using “goo”. Put some acetone in a jar and add a snippet of natural-color ABS (which is included with your 3D printer). Shake it up and let it dissolve for 20 minutes. Heat up the printing bed for 15 minutes. Use a small paint brush and apply a light film of “goo” to the glass plate.
Don’t be shy about it, dip your brush deep into the jar to pick up some of the dissolved milky ABS. The acetone will sizzle and dissolve but leave a light glaze on the glass plate and this will make your parts stick remarkably well. Take caution when removing the part! You may need to run the underside of the glass part under cold water to get the part to release! Remember to label your jar and keep it away from little hands.

Quick tip: Don’t let the goo drip on your beautiful acrylic panels- acrylic and acetone are not friends.
