Acetone vapour smoothing ABS 3D prints at home, the simple way. Will your parts warp? At CNC3D we put it to the test on an ABS enclosure. 🧪
Plenty of people have talked about acetone smoothing and a lot of you are keen to try it. In this video, we show you a practical application: how it's done, plus a really simple setup you can build at home. 🏠
Our setup:
🔹 A food grade container with a glass base and a clip-on lid.
🔹 A bit of paper towel in the bottom, with just enough acetone to wet it.
🔹 A small stainless steel mesh on top of that.
🔹 Your parts resting on the mesh. Close the lid and let the vapour do the work.
The big worry is parts deforming and changing shape. This case needed to fit together well, so it was a proper test. Take a good look at the fit, then tell us what you think in the comments. 👀
Here's what we can definitely confirm: it's a really solid feeling case. Compared to a standard 3D print it feels more solid. Just tap it and it feels like a harder plastic all round. The idea is letting the layer lines bond together a little more deeply. 💪
Which materials suit it?
🔹 ABS: what we used here. Its higher temperature resistance makes it a great pick for parts that need to handle some heat.
🔹 ASA: this works as well, with better UV resistance for parts that live outdoors.
🔹 PLA and PETG: acetone generally won't smooth these, so check your filament before you start.
⚠️ Safety first: acetone is highly flammable and the fumes aren't good for you. Work somewhere well ventilated, well away from sparks, flames and heat. Keep that container for this job from then on, not for food.
It was a fun little project. We hope it inspires you to try improving the strength of your own parts. 🛠️
