Early experiments with metal printing with a Budaschnozzle 1.1 are looking good. Repeat: early experiments (Tin 95.8%, Copper 4%, Silver 0.2%, McMaster 76805a61). If you can wait a few days before trying this out, I'll let you know if it destroys the nozzle. Fun fact: silver solder will stick to painters tape.
The flow cuts out after about 15mm of 3mm feed, we might be able to extrude continuously with a larger thermal mass around the nozzle (metalschnozzle?). Alternately we could print in short bursts through some sort of g-code trickery.
His plans for the future:
- Faster extrusion at higher nozzle temps (going to give an all metal noz a shot)
- Printing through a glass nozzle (I've got some lab grade glass eyedroppers on order that I'll try to hack into a hotend
- Smaller diameter filament (should cut down on the heat soaking up through the filament)
