Viscotec. In industrial applications, the use of additive manufacturing processes is increasing as they give benefits in comparison to conventional processes. They fit for example the production of geometrically complex component as bionic structures, but also the production of prototypes and standard components through power-based and melting processes. The use of these processes permit a greater amount of design freedom without incurring extra time and costs through additional steps. This whitepaper presents the advantages and disadvantages of additive manufacturing of components from liquid materials through three methods: Pneumatic dosing unit, Drop-On-Demand (Jet-Valve) and Endless piston principle.
