Case study: Simulating metal printing
- [Woman] A 3D printer manufacturer might choose to have its users rely on broadly available software tools to slice the model, and do some level of pre-built simulation. Alternatively, particularly if they have a somewhat unique process, they might elect to have a proprietary software system. In this movie, we'll talk about the proprietary software used by Desktop Metal in two of their systems and the simulation philosophy in each. - [Man] In the Desktop Metal studio system, the raw material is rods composed of a high percentage of metal powder in a plastic carrier. The carrier is melted in a process similar to film and printing. They call this bound metal deposition. The resulting parts are then put through a debinding and sintering process to remove the polymer carrier. The process is most similar to film and printing, with the additional complication that the part will shrink during sintering. More shrinkage will…
