Material considerations
- [Narrator] Low cost metal printing is available for a growing list of metals. There are two main paths to follow. You can bring an end-to-end system in-house to print, debind, and sinter, or you can print in-house and vend out the debinding and sintering. Depending on the material and your in-house capability, one or the other may make more sense. The requirements for debinding depend on the binder. The manufacturer of your material will provide a procedure for debinding. This may involve exposing the print to an acid or other chemical solvent or it might be done by heating the print using specified times and temperatures. Requirements for sintering depend mostly on the composition of the metal powder. A backbone binder, a component of the binder that survives debinding, usually persists into the sintering stage to hold the print together. - [Co-Narrator] It's important to prevent oxidation during the debinding and…
