Acetone — the solvent used around a 3D printing workshop to clean ABS and ASA residue off tools, and to wipe a build surface clean before a new job.
Acetone dissolves ABS and ASA, so it lifts baked-on residue from tools and plates and leaves a build surface free of the grease that stops a first layer sticking. It also welds ABS parts: soften both faces, press them together, and they fuse into one piece.
Acetone is highly flammable and evaporates fast. Use it with ventilation, keep it away from heat and sparks, and keep the cap closed. Do not use it on coated PEI sheets or on the printer’s own plastic parts — it can damage both permanently — and do not use it on PLA, which it will not dissolve but will haze and distort. Wear gloves and avoid breathing the vapour.
The Acetone costs ฿50 including VAT at Print My Design. It is in stock; stock at each branch is shown on this page.
No. Acetone does not dissolve PLA — it hazes and distorts it. It works on ABS and ASA.
Not recommended: it can permanently damage the coating. Use isopropyl alcohol on PEI instead.
Brush a little on both faces until the surface softens, press them together and hold until dry. The joint fuses into the part.
Cap closed, somewhere cool and ventilated, away from heat and sparks — it is highly flammable.
