SlurryAM is a revolutionary metal 3D printing technology that uses a slurry-based medium instead of traditional powder beds. This patented process uses voltage-driven metal consolidation through a three-step gap jumping, particle sintering, and consolidation process.
Voltage creates a conductive pathway through metal particles suspended in carrier fluid. The electrical arc jumps between the energy source (TIG torch tip, laser, plasma arc) and the metal particles.
Heat generated from the electrical current causes adjacent metal particles to sinter together. Current increases as particles form conductive pathways.
Continued current application ensures complete consolidation and solidification of the metal mass into a solid, homogeneous structure.
| Technology | Medium | SlurryAM Advantage |
|---|---|---|
| Powder Bed Fusion (SLM/DMLS) | Dry powder | Gas-free, no powder recoating delays, safer with reactive materials |
| Electron Beam Melting (EBM) | Dry powder, vacuum | Works in any environment, no vacuum required, material recovery |
| Binder Jetting | Powder + binder | Direct consolidation, no post-processing sintering, better mechanical properties |
| Wire Arc Additive (WAAM) | Wire feedstock | Better resolution, complex geometries, voxel-level control |
| Metal Injection Molding (MIM) | Metal powder + binder injection | Additive (not subtractive), better for complex shapes, no mold required |

This technology represents a novel approach distinct from traditional powder bed fusion, wire arc additive, and metal injection molding processes. The use of suspended metal particles in a carrier fluid with voltage-driven consolidation is a unique combination not found in prior metal additive manufacturing methods.
