how to patch up your prints.

how to patch up your prints.
Found this, figured I'd share. Here are steps to make your print the best it can be. Fix the cracks and holes in your prints.

Here is how to finish your part:
1. Using your knife, trim off all of the external support. Do it as cleanly as possible. Spending a little time here will save you trouble in the next steps.
2. Use the sandpaper to sand the part as smooth as possible. You won't be able to eliminate every tiny ridge, but you can get it pretty good. You will probably have to do this by hand as an electric sander can heat up the ABS and ruin the part.
3. Prepare an ABS/Acetone slurry:
3a. Put the ABS filament in the jar.
3b. Pour in the acetone.
3c. Tighten the lid and shake until the acetone dissolves the ABS and forms a slurry. It is nice if it ends up the consistency of thin paint.
4. Paint the part with your slurry. This should seal the cracks and smooth out the finish.
5. Let the acetone evaporate and the part dry. It shouldn't take long.
