Topic: 3d print part crack line start to show up after acetone bath a week

Hi,

Hope I got the right forum.

Crack line start to show up after a week on my 3d printed part with acetone bath treatment, have anyone encounter this before? I spend hour of making the parts look smooth and shiny with acetone bath but crack line start appearing at the layer joins after a week. I am thinking because the abs contracts when it dry from the acetone bath. Any idea or fixes?

Thanks

vapor or liquid? ABS absorbs liquids and acetone dont wash out with water etc. or need thicker walls or closer layer settings if vapor done it

Try sticking the parts in the freezer for several hours. That stops parts warping when they've had acetone soaked into them to strengthen the part, so it may well help here too.
