3D CAD Modeler, ABS Material Separation Fix

So here is a neat trick that I found out about that I wanted to share.

The Setup

Needed:
  1. 100% Acetone, ie: nail polish
  2. ABS scrap, ie: raft or small pieces of ABS off the spool
  3. Disposable Gloves, tweezers, and plastic silverware (for application)
  4. Disposable container for making the slurry

Make Slurry and Apply As Need

  1. Add Acetone and ABS together, and tip up your container to create a pool on one side of the dish. There is no formula here, just add some acetone lets say two tablespoons and add a couple of small pieces of ABS to fill up the pool of acetone.
  2. IT REALLY SMELLS, I recommend doing it outside with plenty of ventilation.
  3. After you get a consistency like a paste apply to cracks
  4. I have used blue tape to the back of the part and leveled the part
  5. Add slurry till it slightly overflows
  6. Allow to dry/set - time varies
  7. Use sand paper to smooth - Start with 100 grit and go 200 grit for nice finish
