The Phenol Direct Binding (PDB) process is a future-proof solution for 3D printing of complex and filigree sand cores and molds and can be used as an alternative to furan resin. Casting molds printed with phenol 3D-printing are characterized by particularly high resistance to thermal stress and dimensional stability.
- High tensile strength:
Cores printed with phenolic resin show an elongation at break of 250 - 500 N/cm³.
Unprinted sand can be recycled and reused up to 100%.
- Material variety:
Regardless of the pH value of the material, we also offer 3D printing of special sands such as Cerabeads, Kerphalite and Chromite in addition to quartz sands.
- Quality assurance:
Due to low loss of ignition as well as low gas formation and hot deformation, high-quality casting results can be achieved.
Vehicle technology manufacturer Lütgemeier increases flexibility and productivity using our industrial 3D-printing system VX 1000 in order to supply the high-performance car tuning company BRABUS.
