We offer a PhD Position at the NeptunLab. The NeptunLab is the highly interdisciplinary research group of Prof. Bastian E. Rapp at the Department of Microsystems Technology (IMTEK) at the University of Freiburg. Research interests include the development of novel materials, technologies and processes for structuring materials and industrial applications. The work of the NeptunLab is published in the most important international journals including Lab-on-a-Chip, Advanced Materials, Angewandte Chemie and Nature and has been featured in national and international radio and print media including the BBC, the New York Times and the Discovery Channel.
Precise shaping of polymer components is essential for many fields in science, industry and everyday life. Especially highly precise microstructuring is of high interest for the generation of novel optical components. Today, classical subtractive methods such as diamond turning, laser ablation, milling and eroding are regularly used for shaping polymeric precision parts. However, for high throughput industrial scale fabrication injection moulding remains the method of choice.
The fabrication processes of the future must ensure flexibility for testing of designs and small-scale fabrication of parts on demand. Nowadays, injection moulding requires the costly and time-consuming fabrication of moulds. To make injection moulding ready for the 21st century, novel methods for faster and less expensive mould productions need to be developed. This project therefore aims at developing new methods for generating moulds by using replicative processes, i.e. moulding of low-temperature melting metals and metal alloys. The concept is based on a metal moulding process invented and patented by the NeptunLab.
Activities and Responsibilities
