SPD

Basics

• An Abbreviation for Selective Powder Deposition
• A form of metal 3D Printing
• Uses a crucible that is filled with either filler powder or metal powder
• This is then put in a kiln with filler metal above which seeps into the metal powder, but not the filler
• Thus it casts a precise part (No shrinkage like sintering methods)
• May not be better than other methods (Mig 3D Printing, lost pla casting, 3d printed part to greensand casting etc, but it is worth looking into
• Also may aid as a development tool for working with powders in a cnc enviroment
• May be useful for other powdered materials

Existing Development

This group seems to be the main, if sole developer:

• Their Main Website
• An introductory Video
• we can contact them to see if they will open source their designs
