OK I made a second attempt at sintering a part. I printed another 1"x1"x1/8" part. This time I printed it solid infill. I think I may have heated it up too much during the filament burn off process because the part caught on fire. I ended the experiment here. I think I am done with the experiments at this point because my foundry is not able to heat up enough. Before now I was only hitting temps around 1300degree F for melting aluminum. I have some new element wire on order now which should be able to get me closer to 2000 degree F.I will report back when I do more with this.
