Binder Jetting

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

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
