3D measuring devices in medical technology
Surfaces increasingly have to exhibit special properties. This is particularly true for medical technology: Implants and prostheses are precisely ground to produce specific roughnesses or smoothnesses. Only in this way can the artificial replacement enable natural movement.
Webinar with practical relevance
In his presentation, Christopher Wallmann first classifies the various measurement technologies - white light interferometry, confocal microscopes and profilometry - explains their advantages and properties, and highlights Mahr's range of 3D measuring instruments.
However, one focus of his presentation is on the concrete practical relevance: The 3D measuring instruments are used, among other things, for the standard-compliant roughness measurement of catheters, tubes, tools, stents, biosensors as well as joint implants and dental implants. The best thing is to take a look for yourself:
Confocal thread measurement
Using dental implants as an example, Wallmann demonstrates a measurement of thread geometry using a confocal system. On the thread, the geometry including the distances is recorded in a measuring range between 300 and 400 micrometers. "You can also use it to look at texture direction, for example, or to check load-bearing components to make sure that the specifications of the implants are met," Wallmann explains. The geometry measurement of the implant can be recorded areally, as another measurement example shows. The confocal microscope can also be used to measure the topography of crowns, for example to check their wear. Knee joints also play a major role in medical technology, as the trade fair expert explains: On this largest human joint, it is a matter of highly polished surfaces, where roughness measurements with repeat accuracies of <0.2 nanometers are required.
Other industries in which Mahr's measurement technology is used include the automotive industry, and here in particular the areas of car bodies and engines, as well as in materials science, electronics, the semiconductor industry, and in printing and security systems.
