IMPLANTS FROM WATER


Innovative production procedure by means of fine or micro waterjets


LUKAS TONETTO


Micro waterjet cutting is already being used successfully in the production of implants. By


means of a new injection procedure used by Swiss Microwaterjet AG, surface structures can now also be processed using pure water.


Medical technology is under a great deal of pressure to innovate, as are other medical areas, in particular with regard to implants. This pertains to medicine itself on the one hand, but also to the manufacture of the materials being used on the other hand, as well as the actual production of the implants. In addition to new procedures such as stereo-lithography for the manufacture of biocompatible implants made of bio-ceramics, boring and cutting, implants are also being produced in well-known procedures such as vulcanisation (silicone). In the field mentioned just above, a new branch is meanwhile making its presence felt, which just a few years ago was unheard of in medical technology: waterjet cutting and micro and precision waterjet cutting, a development of Swiss Waterjet Group with its Microwaterjet product and the procedure known as AWJMM (abrasive water jet micro machining).
