Process description
Binder jetting's process is very similar to that of powder bed fusion. it involves placing down a layer of a powder material onto the whole print bed, but instead of melting the powder together with a heat source a print head deposits a liquid binder the sections of the layer that will be in the final part. after the process is complete the part is normally left in the powder bed to let the binder fully cure, and is then cleaned of excess powder.
strengths
- low energy:
- material flexibility: binder jetting can be printed with any powder material that can be held together with a liquid binder
- scalable:
- no need for supports: very similar to powder bed fusion the excess powder acts as natural supports
weaknesses
- material properties
- post processing
Technologies
There are a number of specific technologies that can vastly change to capabilities of a printer.
- multi color
- metal sintering
