Question

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

Explanation:

The text clearly states that after the material is deposited, 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
