  1. I found a method on YouTube that seemed to improve on this method a little. Use a rice cooker and pour the acetone in when it is still switched off. Place the part inside, place the lid on, and then switch the rice cooker on. When the glass lid starts fogging up, start the 30 second count.

  2. I have only tried acetone bath once, and it came out pretty well. Here's the image: http://1drv.ms/1PKyXlAI used a tinfoil loaf pan, and sat it on the heated bed of my printer, with the temp set to 70C. I used a lot less acetone than you did – just a couple teaspoons. I hung the ring on a piece of wire, poured in the acetone, then covered it with foil. I let it sit for roughly a minute (I didn't time it like you did), and then took off the foil and let it sit for an hour or so.One thing that I did different that could make a difference for you is that I refrigerated my part in advance, so that the acetone would have more of a tendency to condense on it. I am very pleased with the results.

  3. Good video but you should probably be lot more careful with containing the acetone. We don't want people playing around with a flammable carcinogen like its harmless water after all. Definitely should be using eye, breath, and hand protection at the very least. If you enjoy printing with PLA, might I suggest trying tetrahydrofuran with appropriate research on the chemical of course.

  4. this is a bit stupid, you have to redesign this. Use an hermetic recipien and a hot surface as a heating bed.
    its dangerous because it can burn and also because you are inhalating acetone steam

  5. Acetone heated vapour can cause severe brain damage, you need to seriously check safety and have very good ventilation. Sorry about the comment. But thank you for the video.

  6. Idea. sand first all the way around with 400 grit, including side that was on the build plate. Then acetone. A quick sand should knock off all the extreme defects, the acetone will give it a polished look. Maybe…

  7. Hi bill, would this work with PLA? And where do you get the acetone? I tried an acetone nail polish remover with a 'cold' version of this and it turned the PLA into mush.

  8. It looks like a great idea until you realise you have a perfect combination to make one hell of an explosion…glass and flames in the face too.  Oxygen, warm fuel and the thermostat inside the wok, that is a million miles from intrinsically safe. When the wok thermostat relay opens the heating elements are slightly inductive so a spark is generated on the contact each and every time. If the fuel source acetone, finds it way inside (and there is nothing to stop it) then you have one hell of a bang potential on your hands.  People are killed routinely after trying to weld containers that have been purged of fuels several times with water. The slightest amount of fuel mixed with air makes a massive bang.  I once did an experiment when I was young and stupid with 2 litre bottle with a small amount of fuel source and a fuse.  We put it inside an abandoned car at a rubbish tip.  The explosion was immense, just 2 litres with a tiny bit of fuel plus air and it blew the boot open.  DO NOT TRY THIS AT HOME.  Recipe for disaster.  If you must, heat the wok, take out the power plug and take the whole affair outside, touch the pan with your fingers to make sure it is not Too hot, then add you fuel.  Remember the element underneath may be very very hot, so don't spill any there or you will get one hell of a BANG.  Just remember the triangle of combustion, heat or electricity, oxygen and fuel.  Play will all three together, sooner or later someone will always get burnt or naturally selected.

  9. Nice challenge conquered. Im here from Painless's page from his mention of your 3d printing. Im building quadcopters and have some 13mm carbon tubes coming. He showed your arm ends for 16mm tubes. Im just south of Richmond. Ide like to set up the makerbot I have access to at work to mod the 16 into a 13 diameter. Is scaling like that possible? Could you perform the mod and post the data? Thanks.

  10. I have seen several ways to do this but the wok is the most unique. Going to give it a try myself. But I think a little longer time will smooth thing out more. Thanks for the idea.
