Makerspace
A Makerspace has been set up at pmd where students can learn how to use rapid manufacturing processes in a practical way. Consisting of various additive manufacturing systems, a laser cutter as well as workbenches, tools for post-processing and assembly, the Makerspace offers students the opportunity to realize their results in the form of the developed products as part of the courses “Tutorial Design for Additive Manufacturing” and “Smart Products, Engineering and Services” and thus makes the development and manufacturing processes tangible. Students working on their thesis or an ADP at pmd can also produce prototypes, auxiliary tools and test specimens in the Makerspace. The Makerspace is located in room L1|10 112 all year round and will additionally be extended to room L1|10 102 in the summer semester as part of “Smart Products, Engineering and Services”.
Equipment
- Components can be produced on eight Prusa i3 MK3S+ using fused filament fabrication. In this process, a polymer layer (e.g. ABS, PLA or PETG) is applied to the current layer by means of an extrusion head. The build platform moves in the x- and y-plane and the extrusion head in the z-axis, which gives the process its three-dimensional character. One of the Prusa i3 MK3S+ is equipped with a multifilament system, which enables several types of material to be deposited directly into a component.
- On the Formlabs Form 3, polymer components are produced from synthetic resins by means of stereolithography. A building platform that can be moved in the z-axis is immersed in the synthetic resin. A UV laser exposes the resin layer by layer in the x- and y-plane and selectively cures it. The finished component is removed from the build platform and cleaned of liquid resin residues in the washing system belonging to the system. The material is then completely cured in a UV oven.
- The Rayjet 50 laser cutter from Trotec enables the extremely fast production of two-dimensional components. The 30 W CO2 laser can cut and engrave various wood materials, plastics, glass and leather on an area of 457 mm x 305 mm.
