Question

mj: drop on demand
use the information below to answer the question presented
drop - on - demand material jetting is useful because of its ability to print not only continuous lines of resin, but also precise droplets of resin. this ability makes it useful for jewelry and machine parts that require very high detail.
like regular material jetting, drop on demand uses two build materials: a dissolvable support material and a build material. however, the build material used is a wax - like material rather than a photopolymer resin. after the material is deposited, a milling blade flattens the top surface of the build, removing any bumps or imperfections. the process continues until the piece is finished
what is the milling blade used for in drop on demand printing?
depositing a dissolvable support material
creating a mold using the lost - wax casting process
flattening bumps and imperfections on the top surface of the build

Explanation:

The text states that after the material is deposited in Drop - on - Demand printing, a milling blade flattens the top surface of the build, removing any bumps or imperfections.

Answer:

flattening bumps and imperfections on the top surface of the build
