Question

mj: new developments use the information below to answer the question. micro - jetting is an exciting new development in the world of material jetting (mj). an israeli 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 bonus 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. with micro jetting, what is left after the resin evaporates? an empty build plate a fine powder a reinforced polymer a layer of metal

Explanation:

The text clearly states that "After the resin evaporates, a layer of metal is what remains."

Answer:

a layer of metal
