The Rotoforge project has also been progressing somewhat, in that we have developed a new magnetic non contact thermometer for measuring temperature in the rapidly rotating deposition region cheaply and relatively directly. I talk about it, and some of our other developments in my blog post.
we have also opted to pursue some high temperature FDM direct metal extrusion approaches using EDM drilled glow plugs…and other configurations.
I have not been on these forums in a while. Figured I would post a few updates.
