Laser Micromachining Tool 
The Laser Micromachining Tool is a microSTRUCT vario from the company 3D-Micromac AG.
The system is able to produce micro structures in different kinds of materials like metals, ceramics, composite materials, etc.
The machine is located in the basement of building 346 under the cleanroom.
The user manual(s), user APV(s), technical information and contact information can be found in LabManager:
