Metal slurries for additive manufacturing of technical metals
3Dresyns® metal binder slurries are ready-to-use feedstocks designed for additive manufacturing routes based on highly filled micron and submicron metal powders (very high solid loading), including stainless steel, titanium, W–Mo alloys and Co–Cr alloys.
These systems are designed for Metal Indirect Production (MIP) via injection in 3D printed durable or sacrificial molds, and for alternative direct manufacturing routes such as high-temperature jetting.
Available metal slurry families
- Metal Slurry MS Stainless Steel 316L
- Metal Slurry MS Titanium
- Metal Slurry MS Wolfram (Tungsten) – Molybdenum (W–Mo) alloys
- Metal Slurry MS Cobalt Chrome (Co–Cr) alloys
Compatible production routes
1) Injection in 3D printed molds (MIP)
- Injection in durable molds for repeatable tooling workflows.
- Injection in sacrificial 3D printed molds for complex geometries, undercuts and difficult demolding.
2) Alternative direct manufacturing routes
- Direct printing systems such as high-temperature jetting (application- and system-dependent).
Key features & benefits
- Excellent dispersion and injection flow of micron and submicron metals with additions up to 65% volume concentration.
- Very high resolution by direct printing (jetting) or by high-temperature injection in durable or sacrificial molds.
- High quality final parts (process-dependent).
- Controlled and reproducible shrinkage during debinding and sintering (workflow-dependent).
- Minimum expansion coefficient and a wide debinding temperature interval designed to reduce the risk of micro-fractures (material/process dependent).
- Very high final resolution down to ~20 microns (geometry and process dependent).
