It has been several years since I looked into 3D printing. I bought some Reprap parts and had 2 major electronic failures which turned me off. I also started lost foam casting in foundry set up an old friend gave me. 20 minutes foam cutting on my CNC mill, overnight drying of drywall coating, 30 minutes of heating and pouring and I have a real aluminum part that can weigh as much as 16 lbs!
However I am again interested and looking to find the best quality printing head. Dual heads would be even better. Tons of junk on Ebay, so who makes a reliable print head?
My CNC mill has an 18” work cube, 127mm/sec motion, and an industrial PLC with analog I/O for temperature control for the 12” square heated bed, and is fully enclosed.
Thanks,
