Experiencing Additive Manufacutring

Our Research

Our institute has access to more than 2000 mof Additive Manufacturing (AM) research laboratory space. Over 25 scientific associates research in more than 25 facilities for metal and 15 facilities for polymerbased AM. Our equipment covers the entire AM process chain.

Electron Beam Melting (EBM)

Electron Beam Melting (EBM) is a powder bed based Additive Manufacturing (AM) process, which does not require any support structures. EBM builds components layer by layer from bottom to top using metal powder. Different from any other AM process, EBM has a unique preheating routine. Not only does preheating occur from the top, but every single layer is preheated before being selectively melted by an electron beam under vacuum. As a consequence of this layer wise preheating, the powder layers are sintered.

Laser Powder Bed Fusion (LPBF)

During the LPBF process, also known as metallic 3D printing, a LPBF system builds up a component layer by layer: Laser radiation melts powder selectively according to the geometry information of the respective component layers. After each layer, the substrate plate is lowered by one layer thickness. In a next step, a new powder layer is applied and another layer is melted.

Laser Material Deposition

Laser Material Deposition is a laser based cladding process. A laser beam locally melts the surface of a component, metallic material is guided into the melt pool the the material is completely melted reuslting in a metallurigical bonded layers. Repeating this procedure, multiple layers can be applied and complex geometries can be manufactured in a near-net-shape manner.

Extreme High-Speed Laser Material Deposition (EHLA)

EHLA is a laser based cladding process. Unlike conventional Laser Material Deposition, the laser melts metal powder particles while they are above the melt pool. Hence, liquid material drops into the melt pool instead of solid powder particles. The process achieves a high process speed (up to 500 m/min), a layer thickness from 20 to 350 μm, dense and metallurgical bonded layers and a high material efficiency (up to 95%). Utilizing EHLA, almost any alloy can be used for coatings (e.g. iron-, nickel-, aluminum-based alloys, Metal Matrix Composites (MMC)).
