BASF Ultrafuse 316L (indirect metal printing)
BASF Ultrafuse 316L is a novel metal-polymer composite in filament form for easy and fast material extrusion of green compacts. These green compacts can then be debinded and sintered by standard processes at an external service provider. This gives low-cost full metal components.
Main applications: spare parts, maintenance, prototype construction
Advantages: High temperature resistant, strength
HAGE3D has been involved in the production of metallic components in indirect metal printing for many years. The starting point was the EU project Repromag, which aims to develop and validate an innovative, resource-efficient production method for rare earth magnets, the efficient production of magnetic parts with complex structures and geometries.
The new, applied manufacturing method is referred to as the SDS process (shaping, debinding, sintering, debinding, sintering). The binder-based sintering solution has been known and used for many years as MIM (Metal Injection Molding). The whole process looks like this:
Shaping in indirect metal printing is done by a 3D printer and replaces injection molding in this process. Meanwhile, a variety of metals are available for the SDS process:
- Stainless steels: 316L – 1.4404 | 17-4PH – 1.4542
- Maraging steel – 1.2709
- Super alloys: IN 718 – 2.4668 | IN 625 – 2.4856
- Light metals Ti6Al4V – 3.7165
- Hard metals WCo
The optimization and coordination of the individual sub-processes is currently the focus of further development in the SDS process.
As part of CerAMfacturing, HAGE3D is part of the EU Horizon 2020 project entitled:
“Development of ceramic and multi-material components by additive manufacturing methods for personalized medical products”.
Together with Europe-wide partners, indirect ceramic printing is being developed here.
The focus is on alumina and zirconia.
