I’ve printed two small models with ABS on our office LulzBot Mini, and some residue was left on the printer bed.
I tried removing it with acetone, but even after some thorough soaking & rubbing, some still remains:
When I touch the bed it feels completely smooth, ie. this is probably a super thin layer of residue.
- How can I clean the bed better? Is there a stronger material than acetone, or perhaps something I’m doing wrong?
- Is it safe to print over this tiny layer of residue?
