Here's something that should make plastic life a lot easier. Fuse parts, smooth, shine and texture prints, even cast ABS at room temperature.
The blog post above does a much better job of explaining and demonstrating than is possible in these descriptions. Check it out!
!! Use in a well ventilated area and avoid skin contact !!
Mix 1/3 filament clippings to 2/3 Acetone in a cleaned out nail enamel/polish container.
Swirl about and wait to set.
Brush on surfaces to be joined and press together, hold or support long enough to set. Such as Plastic T-Slot http://www.thingiverse.com/thing:10261
Shine, Smooth, Texture:
Experiment with different concentrations of filament to Acetone and brushes to paint a layer over your prints, smoothing them or lay a textured surface against surface transferring desired texture.
Print PLA molds. Apply multiple applications of ABS Glue as the Acetone evaporates. A light concentration to straight Acetone at the top can help smooth the top surface. The ProtoParadigm Logo in the images is an example of this process. Dried glue can be peeled or scraped off where applied accidentally.
These are only a few of the uses we've explored. Make some, try it out and see what you come up with.
