Basics
- Steel parts almost directly from 3D prints
- Based on 3D Printing Investment Casting
Steps:
- 3D print a form
- Make a cast form with Plaster of Paris (Or use a "greensand" mold/cast? )
- MIG weld into it
Low Temperature
- For aluminum, ZA, brass - plaster of paris will work
- For steel, higher temperature investment casting slurry needs to be used. This appears to be more advanced, and slurries may not be available transparently. (Refractory Cement? I have seen this being used for small scale forges, it can be found at hardware stores.
Working Document
Comparison to metal wire fed FDM
Comparison to Powder (Sintering or Melting Methods)
- Simpler lacking lasers or electron beams
- More sealed ie not porous
