No, I never tried. It seems to keep toggling down on the project priority list.

Yeah that video is DavidF - he's a mod over at Alloy Avenue. The vacuum table is one part that is used for the investment process. The acrylic domes you can get from a jewelry supply house like rio grande. The part you're referring to is called a perforated flask. You'll need a vacuum caster to make...

if the pieces are relatively small (fits within a 5-6" flask) look at vacuum casting using investment.

yeah, that demo video showed pretty horrible results. If PLA already works better for this type of thing, why spend four times as much money on moldlay? There doesn't seem to be any advantage. Agreed, it's not that much easier for post processing than PLA, not at that price point. I am interested i...

Their online info is showing that you can use it for both types of casting, and they have a picture of an object being cast from a clam shell negative filled with some kind of resin. The video on their site is painful to watch - the mold leaking was jaw dropping. It sands easier than PLA but not as...

Acetone works on ABS. I don't believe it works on any other materials. I'd recommend that you not use an electric skillet. I've used one in a double boiler arrangement but it works too well. Acetone boils at 130F so it lays down an excessive amount of acetone on the surface. The surface, while smoot...

Any reason not to use Nylon or its variant so print M2 replacement parts? I've got a couple of spools of Taulman Bridge http://taulman3d.com/bridge-features.html. Its a hybrid nylon. Shrinkage is the only concern that I can see that would be problematic.

Very cool Jules, thanks for sharing. I'm adding it to my list of things to try next.

I've looked at XTC3d. It works well. Acetone is a little faster and cheaper. I'm having decent results with my paint can system. I'll post it up when I get pics.

I've got the metal motor mount but was waiting for some printer down time to install it and the dampers. Ask and ye shall receive.

Thanks Jules and sorry for the confusion. I am not doing the acetone vapor smoothing in the printer enclosure. I'm smoothing in a paint can outside the enclosure. When I stop the print to change filament, I would coat the top edge of the bottle with a little acetone to make it sticky. In the pic bel...
