Description

IMTEK belongs to the world’s biggest and leading academic research centers on microsystems engineering. The chair of application development conducts research on micro-fluidic systems and printing technologies, amongst others the so-called StarJet technology. This technology allows for the direct printing of molten tin and aluminum alloys as free flying micro droplets. Based on this technology, a printing system for 3D prototyping and for microelectronic applications for research was developed and is successfully utilized in the lab: This equipment enables experimental investigation of applications ranging from industrial production to 3D prototyping of metal microstructures. We are looking for a

 

Scientific Researcher / Research associate (m/f/d)

 

In the field of advancement of metal printing, vertical interconnecting, and multi-material additive manufacturing

 

By integrating multiple (3D) printing technologies, including Fused Filament Fabrication (FFF), high-precision inkjet printing, molten metal deposition (StarJet technology), and in-line direct soldering of electronic components, the multi-material additive manufacturing enables customized, high-performance electronic structures with improved efficiency and sustainability. Our research group developed a Multi-Matieral additive manufacturing platform that improves the affordability and accessibility of electronics manufacturing for small and medium-sized companies, for example, for rapid prototyping and small series production. Resource-efficient additive manufacturing eliminates the need for chemicals, solvents, water and wastewater in PCB production. The sustainable solution also opens up geometric design freedom. Complex and customized shapes and designs are attractive for various components, such as glucose test strips, solar cells, electronic prostheses, smart wearables and batteries.…
