| Abstract Scope |
Additive manufacturing through shaping-debinding-sintering of metal filled polymer materials is a great alternative to beam-based methods for smaller parts. It involves the shaping of a part through fused filament deposition of a highly filled filament (fillgrade > 55%), which can be done using consumer-grade 3D printers. This is followed by a step where the main binder component is removed by a solvent, creating a green body. The green body, held together by a “backbone” polymer is then treated in a furnace, where the backbone component is thermally removed followed by a sintering step producing the solid part. This process is generally lower cost, uses simple equipment and does not involve the handling of metal powders, making it ideal for distributed manufacturing. In this talk, we will show the application of this technique to the manufacturing of parts from high-value, high performance materials, including titanium, copper and superalloys (A718). |
