ABS boiling ? Fail with acetone bath

Post by Boris »

Whew... What is this ? Why this happened ?

I did many acetone baths before but never got same results.
The model didn't have any contact with acetone. Just acetone fog(steam) at ~100c degrees.

Do you have any ideas how to solve it ?

P.S. Honestly - it's new for me ABS plastic "Wanhao".

Yes, it's new one for me.

oh, that sad.
Next time I'll try "warm acetone bath".
I mean not 100c for 5-10 minutes, but lets say 50c for an hour.

Sorry I don't have more details (may have been YouTube video) but I saw someone using a rice cooker. About 2 tablespoons of acetone in, then metal grate with spikes and 3D print went on the spikes. In about 2 minutes the acetone evaporated and the print was ready.

I see there are many demos in youtube with search criteria "rice cooker acetone 3d print". Possibly print a handful of small 3D objects to test out acetone process variants, since rice cooker temps may vary.

Good luck Boris.

I've been using a room-temperature paint can method. You stick some paper towels to the inside of a paint can with magnets, wet the paper towels down with acetone. Put the part on the inside of the lid, put the can over it, and wait for a couple hours. Slower, but safer. There was a YouTube video with instructions.

Hi Boris, have a look at my post (GGY) in this "General" section from Wed 21 May 2014 titled: acetone vapor polishing ABS.
There I describe how I perfectly polish ABS parts in an attached PDFs document.
Let me know if it works as good for you as it does for me.
cheers George :)
