We use additive mfg for all kinds of stuff in all kinds of material (Ti, all kinds of plastics) for implants, prototypes, fixtures, tooling, fast molds for simple parts, etc. we have several printers at work and also we have a printer at home and use it a lot. Daughter knows what can be printed and often suggests it. Doll needs a new foot the dog chewed off… “can we print a new foot?” “Sure Mila”.
