Question

material jetting technologies
use the information below to answer the question.
material jetting is similar to an inkjet printer. thousands of tiny droplets of resin are jetted onto a build plate, which is then hardened by a uv source.
printing process
the printing process for material jetting works in a series of steps. the print head moves forward and back on the xy axis, while the build plate goes up and down on the z axis. after a complete layer is finished, the print bed drops. the uv light source then hardens the resin. prints made with material jetting technologies can be made with different colors, different materials, and a dissolvable support structure.
support structure
a dissolvable support structure is used for material jetting which has a minimum impact on the surface quality. currently, fused filament fabrication is the only other 3d printing technology that has this capability. however, the material jetting process will create parts with a higher part resolution.
printing custom parts
material jetting is not a simple, out - of - the - box machine. if you have one of these printers onsite, you must be a qualified, trained operator to run parts. otherwise, you can upload your design files online and have them printed by a third - party provider.
what benefit does a dissolvable support structure have?
it removes the need for curing a print.
it adds density to a print.
it has less impact on the environment.
it has a minimum impact on surface quality.

Explanation:

A dissolvable support structure in 3D - printing (Material Jetting here) is designed to support overhanging parts during printing and then be removed easily without leaving significant marks or affecting the surface quality of the final print. It doesn't remove the need for curing (curing is done by UV light as described), doesn't add density in the way described, and there's no indication in the text about its environmental impact. The key benefit mentioned is its minimal impact on surface quality.

Answer:

It has a minimum impact on surface quality.
