Gentle processing of medical instruments and implants

The manufacturing of medical instruments and implants is characterized by smaller and smaller structures as well as the demand for highest precision in terms of surface quality, absence of burr, and materials residues. While established fabrication technologies increasingly face their limits, laser micromachining provides optimum preconditions for the required quality and precision since machining is accomplished in a contactless way.

Therefore 3D-Micromac developed their new laser system microWELD for welding metals, which enables the user to weld airtight for instance NIOB, titan and different steels. It is possible to precisely adjust the geometry of the weld by variation of the lasers parameters and hence to weld smallest components with a very small heat-effected zone. For instance, seam widths of 0,3mm and seam depths smaller than 0,1mm can be achieved independent from the material.

The system is already used for instance to weld implants. In this case, the welding atmosphere is particularly important besides to the welded joint. This is the reason for the application of a glove-box system in the microWELD, which allows the customer to weld in a highly purified environment. An innovative beam guidance, a special feeding for work pieces, an air-conditioning device, a suction at the point of welding as well as 3D-Micromacs machine control software microMMI are completing the microWELD system.
