    Woah that looks amazing! It’s funny nophead just wrote about this a couple of days ago.

    You amaze me that there is still a patent on this technology. I used to repair machines (a bit of a grand title for what ammounted to a very large heater with water running coolers) using this technology over 30 years ago. The solvent was Genklene an ICI product (1.1.1 TRICHLOROETHANE). It’s banned now, back then we had absolutely no idea how it was damaging us or the ozone layer. You might try searching for alternates of this product.

    The description is spot on by the way, although it doesn’t tell you that if the operatives don’t clean out the resevoir at the bottom the oils will catch fire and the fire department can’t put it out easily.

    Interesting. Let’s stay in touch if we want to builds something like this πŸ˜‰

    Obviously the chamber for the solvent cannot be printed out of ABS, but perhaps another thermoplastic polymer is still feasible.

    Nowadays there is enough choice among environmentally safe solvents. Or at least, 3M, DuPunt, BaSF, e.a. make it seem like that.

    Oh, well thanks then πŸ™‚ It looks really great and I think it would be wonderful to be able to produce such smooth objects with a reprap. I hope that something like this can be built within the community. Also thanks for taking the time to post this, much appreciated πŸ™‚

    On this site there are additional experiments with solvents to smooth parts:
