ABS smoothed?

3

Yes, 20C for 2 hours.

4

What procedure did you use for smoothing it?

5

I put it in a saleable HDPE sandwich box next to a tissue soaked in acetone for 2 hours.

Ive had a pla one on my keyring for about a year now. Broke the 1st one when i sat on it second one when a key levered the key ring the last one I printed with a 45% fill and its rock solid. Ive never had joy from abs but it looks very good smoothed. A finish like this is the only thing that keeps me motivated to keep plugging away at abs.

Do you have a link to the files?

Cool - I found some variations

10

After cold smoothing does it still have the “soft” exterior vapor smoothing does?

11

@Mike_Kelly_Mike_Make Yes, takes about 2 days to return to a hard ABS surface.

so well

13

What do I need to know for acetone-smoothin abs/pla?

14

PLA - no, not with acetone.

ABS - just put the thing in a waterproof sandwidch box with an acetone soaked tissue and watch it. No heat required. Remember it will continue to smooth for a while after being removed.

Very nice, just put a piece of abs next to an acetone soaked tissue and watched it ‘swetting’ :wink:
I’m excited for the result!
