Question

mj: new developments
micro - jetting is an exciting new development in the world of material jetting (mj). a company has developed a process where nano - particles of metal are floating in the resin. after the resin evaporates, a layer of metal is what remains.
with this process, there is a support structure. a liquid with nano - particles of metal is jetted onto the build tray layer by layer. the build volume is at a high temperature to evaporate the resin containing the metal particles. each layer will be solidified before going to the next one. after the project is fully printed, it is then put in a finishing oven to fuse the particles.
a benefit of micro - jetting is that the resin with the metal particles is contained within a container. the operator slips the container into the machine and doesnt have to worry about powder flying in the air.
a process where nano - particles of metal are floating in the resin for material jetting (mj) is known as what?
thermal jetting
major jetting
item jetting
micro jetting

Explanation:

The text describes a new development in Material Jetting (MJ) where nano - particles of metal float in resin, which is the definition of Micro Jetting as per the given information.

Answer:

D. Micro Jetting
