First project work at TC Hutthurm successfully completed

For 15 weeks, 4 mechanical engineering and mechatronics students from the Deggendorf University of Applied Sciences were active in their project work organized at the Hutthurm Technology Campus (TCH). In an initial exploratory phase, an extensive market research was used to select a suitable FFF compact device from available 3D printers as the basis for the demonstration platform at TCH, which meets the requirements for future manufacturing tests on generic structures. The project included the development of solutions for the acquisition and evaluation of sensor data from temperature sensors, humidity sensors and a thermal camera for tracking and monitoring the printing process using proprietary software. These measured values were then graphically processed and analyzed. To determine the mechanical material properties "as printed", a total of 16 tensile specimens with 4 different deposition strategies were produced and destroyed by means of tensile tests in the test laboratory of the Department of Mechanical Engineering. The discussion of the results also provided new insights into the process influences and, with the work in the laboratory, certainly provided a welcome change from the current predominantly online teaching.

With the "Raise3D Pro 2" and extensive measurement technology, the Technology Campus is now well equipped for future project work. The results and findings obtained here serve as the basis for a thesis already underway to further advance the topic of robust and targeted process control and monitoring in 3D printing.
