Renishaw and the Australian dental laboratory Proslab become partners to install what is thought to be the first metal 3D Printing machine for dental applications in Australia. Before working with Renishaw, Proslab introduced a partially digital workflow using 3D scanning and design tools to design dentures. When designed in CAD, the dentures were printed in resin and manufactured in cobalt chrome using traditional lost-wax casting, a traditional method which can reduce part accuracy due to uncontrolled heating and cooling, varied cross-sections and incomplete casting or gas porosity.
‘Achieving a high level of accuracy with lost-wax casting is difficult,’ ‘This means frameworks often need to be reworked after being sent to the dentist and fitted to a patient.’
-Damian Synefias, CEO of Proslab.
Proslab turned to Renishaw to fully digitalise its manufacturing process 3D Printing and purchased Renishaw’s AM 400 metal AM system.
- The machine enables the production of removable partial dentures directly from a CAD file, eliminating the additional casting step.
- Frameworks are built in 40-micron layers of CE marked cobalt chrome powder
- Laser powder bed fusion (PBF), using an ytterbium fibre laser.
Directly printing from a CAD file reduced the number of in-house remakes due to error by 100%.
