Material Jetting

Process description

material jetting is an advanced extension of ink jet tech that 2d printers use. a print head deposits a small amount of either liquid or particle is deposited and fused to the rest of the print using whatever method is appropriate for the material type. this process is most often used with a uv curable resin, but process also exist for metal and cerami

Strengths & Weaknesses

The benefits of Material Jetting include:

• the high precision print heads allow for very fine detail
• easy multi material printing

The drawbacks of Material Jetting include:

• supports are required for overhangs
• post processing. parts often require a second cure in order to solidify them
• limited materials: as of now MJ printing is limited to waxes and photopolymers
• slow print times

	Bad	Good
volume X/Y/Z (mm)	200/100/40	1450/1110/1800
resolution (mm)	.03	.02
layer height (um)	50	10

Technologies

NPJ: created by XJet nano particle jetting involves suspending metal or ceramic particles into a suspension material. after printing the part is put through a sintering step leaving a metal or ceramic part.

SPD: supersonic particle deposition also known as cold spraying is a prosses where metal particles are accelerated to a speed where they will bind to each other.

GDP: gel dispensing printing created by Massivit is a process of material jetting that uses a uv resin gel
