The Fused Deposition Modeling (FDM) process finds use at utg for the flexible, additive manufacturing of foundry models, demonstration objects, and the adaptation of test set-ups. Depending on the area of application, printed filaments are made-up of PLA, ABS, and PETG. The high flexibility in the design, the modification of geometries, and the rapid availability of the models, usually printed overnight, make the 3D printing process a valuable addition to research in industry-related subject areas.
The test stand was set up as part of the DFG-funded utg-MiMed joint project “Incremental Casting: Support Material and Close-Loop Control of Layer Height for Direct Metal Printing with Aluminium”. The modular design allows the use of different print heads. Currently, print heads for the processing of aluminium, copper and salts are used. The printing chamber can be flooded with nitrogen to ensure a low oxygen environment (<50 ppm O2).
