Additive Manufacturing Laboratory

The Additive Manufacturing Laboratory (AddLab) is the result of a cooperation between the Institute of Materials Science, Joining and Forming (IMAT) and the Institute of Production Engineering (IFT). This centralized research facility is a printing pilot laboratory that brings together Laser Powder Bed Fusion (LPBF) – also referred as Selective Laser Melting (SLM) – additive manufacturing technique, materials characterization and topology optimization. By combining those topics, this new laboratory aims to allow the production of parts with complex designs, maintaining the necessary mechanical properties and reducing the component weight.


Equipment

ORLAS Creator RA, assigned to IMAT

The Metal 3D Printer is a Laser Powder Bed Fusion (LPBF) solution capable of manufacturing metallic parts with complex designs, allowing cost-effective part customization with reduced assembly efforts. This equipment is able to print reactive (Aluminum and Titanium) and non-reactive (Stainless steel, Cobalt-Chrome, Bronze and Nickel) alloys, which coupled with its reduced printing area (Ø100x100mm), makes it a valuable tool for alloy development, powder characterisation and parameter optimisation.

SLM 280 HL assigned to IFT

The SLM 280 HL is a powder bed fusion printer with a 400 W single fiber laser. It is a printer for metal parts with dimensions of 280 x 280 x 350 mm max. and a build rate of 15 cm³/hr.

The Institute of Production Engineering also operates a high temperature unit with a build size of  ø 90 x 100 mm. This allows preheating the build plate up to 550 °C for printing materials which are prone to gain high residual stress during the build process, such as Titanium.

For measurement purposes a Hexagon 7-axis arm which allows tactile probing and 3D laser scanning is used.
