FRIEDBERG, Germany--(BUSINESS WIRE)--voxeljet's research laboratory has been doing extensive work on phenolic
resin binders for some time. The new binder offers a number of
advantages for many 3D printing applications, as process engineer Dr.
Florian Mögele can attest: "With this binder, we are able to achieve an
incredible level of resolution and precision in 3D printing. At the same
time, we have also made significant improvements in terms of stability
and sand recycling. And: phenolic resin binders are ideally suited for
processing ceramic and other materials."
3D printed, complicated PDB sand molds surpass even the highest
expectations. The Phenolic-Direct-Binding method, with its impressive
accuracy and increased strength, is setting new trends, especially for
complex molds with undercuts, elaborate details and very small radii.
Various base materials useable
The phenolic resin that is used is not toxic and allows for 100%
recycling of non-printed particle material. In contrast to conventional
binders, the PDB process does not require silica sand to be pre-treated,
which means that it can be easily returned to the sand cycle. Another
advantage: Phenolic-Direct-Binding also allows for the unlimited use of
untreated silica sands with different pH values and ceramic materials.
voxeljet expects to offer the new material-set for various printer
platforms by the middle of 2015. Until that time, the company will be
working on implementing and optimizing the process for relevant printer
platforms: "In PDB, temperature management plays a key role in the
quality of the components. In the coming months, we will empirically
calculate the optimum parameters for all voxeljet printers. This ensures
that the printers reach the best possible quality using a very reliable
process," says Dr. Daniel Günther, Head of Research and Development. Of
course, interested parties can also obtain advance information about the
performance of the new binder method on the basis of standardized
benchmark parts.
