Karlsruhe-Heidelberg Additive Nanomanufacturing Platform

The Karlsruhe-Heidelberg Additive Nanomanufacturing Platform (KHAMP) is an integrative platfrom to accelerate cycled iterations that combine materials and printing method development. It allows researchers in the Cluster to combine their technologies, and to flexibly perform experiments that combine different printing technologies and materials.

It is located between KIT Campus South (LTI), Campus North (IMT, INT) and innovationLab Heidelberg. Please click on the respective instrument to find out more, as well as the contact person and location.
