This is a modified version of the DtMv3 face shield that has been optimized for injection molding. All of the components(including the elastic band) can be injection molded.. This has passed design review by Protolabs as an injection moldable design. We have not ordered injection molded components and have done our validation only against FDM printed versions out of PLA. We recommend ordering a sample run to validate the design before ordering a large volume run. Before ordering from Protolabs, we recommend contacting them as they will have these designs on file.

 A variant of this design is printable on FDM  and can be more easily stacked than the original DtM design in a print envelope is also included in this submission. It removes some of the locating features need in the IM design and simplifies the build process. We recommend using HP MJF for larger scale 3D printing as it allows for autoclaving the cradles for sterilization.

This design was developed by:

• Jeffrey Lipton (University of Washington)
• Mark Ganter (University of Washington
• Tyler Williams (University of Washington)
• Dmitry Levin (University of Washington)

With feedback from Lee Janko from Protolabs.
