Description

15:00 Successful 3D Printing (FFF) with Semi-Crystalline Engineering Polymers Gains from a Scientific Approach
Ernst Poppe, DuPont, New business Development Manager, Grand Saconnex, Schweiz
Application development using additive manufacturing methods in engineering segments is not that different from classical injection moulding or extrusion. It comes down to guaranteeing the functionality of a given component in its environment, thus resisting mechanical loads, dynamic vibrations, hot and cold temperature shocks and chemical contact. It is thus not enough to produce a shape, but also to consider the "internal values" of a material, often dependent on the manufacturing process. Semi-crystalline polymers are considered ideal materials for such functional components, however, they tend to warp and are not always easy to adhere to a "frozen" surface, which is illustrated through PVT (pressure ? volume ? temperature) and DSC (differential scanning calorimeter) diagrams in comparison to amorphous materials. Ernst Poppe will look at how these challenges can be solved and furthermore, how to ensure an efficient applications development process.
