The design for the vapor chamber coming along nicely. Still finishing off the lid and have to connect all the electronics. Also a rather primitive machine in comparison to some of the chambers I’ve seen out there. However the point of this system is to read, the amount of vapor, the heat distribution, inside the heating tray and outside. The ambient temp inside the chamber. Time it takes to heat up. recollecting the leftover acetone by extraction system, etc. I think that is about it, oh except for the fact that the one half will be a vapor chamber and the other side an acetone bath for dipping. 😉
One of the worst irritation factors on a daily basis is the small amounts of filament that is left on a spool/reel. Too little to use on a full print but enough to actually waste a substantial amount of ABS material. All the ideas I played around with regarding acetone glue/cement made me think about how two pieces of ABS filament can be attached together to create less wastage.
A quick informal discussion and motivation from Leslie Bekker helped me on my way with visualizing the design. I consulted with the tool room at TTI Sebokeng, which made a very sturdy and effective design to fuse two pieces of filament together.
Although this does not directly relate to the two main techniques I am investigating, the use of such tools does provide a platform for cleaner, greener and safer user environments, when it gets to Additive Manufacturing, Design and Visual Arts alike.
It is very much in the experimental phase but every sample we tested so far extruded successfully. My biggest concern was that some of the acetone stays behind in the plastic and then heat up too quick and become volatile inside the extrusion nozzle, which in turn would clog up the nozzle (leading to no extrusion at all).
I would love to hear if anybody out there have experimented with the same materials and concepts. Please leave a comment
