Q
Post Processing?
A
De-powder the part and dry it
Infiltration with liquid secondary materials for mechanical integrity

Q
Strengths
A
Simple low cost system Cheap materials Binder soloution typically water based Colour printers available Fast process due to jetting Very little waste material
5
Q
Limitations
A
Limited functional parts Limited strength Poor surface finish Poor resolution Multiple secondary processes
