If you’re thinking of trying the acetone-vapor polishing process to smooth your 3D printed objects you simply must check out [Christopher’s] experiments with the process. He found out about the ...

Many of the Fail Of The Week stories we feature here are pretty minor in the grand scheme of things. At worse, gears are ground, bits are broken, or the Magic Blue Smoke is released. This attempt to ...

3D printers build models in layers, which you can see if you look at a model closely. If you want a smoother, shinier surface, you can achieve injection mold-like quality with a little acetone.

Acetone vapor-sensing experiments using the integrated system: (a) smartphone user interface for (i) function menu, (ii) frequency scanning, (iii) resonance tracking, and (iv) user-defined PID ...
