mj: drop on demand\nuse the information below to answer the question presented\ndrop 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.\nlike 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.\nin drop on demand material jetting, what happens after a layer of build material is deposited?\na refractory material is placed around the wax to create a mold.\na strong titanium material is added for reinforcement.\na milling blade flattens the top surface of the build
