I think small[er] scale injection molding has a ton of potential for local/recycled/lower volume projects that 3d printing isn't necessarily suited for. Brothersmakes [1] sells recycled plastic combs and more using a similar process, products that really wouldn't work well with any modern 3d printer. I've seen similar projects for disc golf discs as well from TrashPanda. [2] The market for hyper-local small scale products is growing, and I think downscaling injection molding fits in well to this. I could order a custom steel mold (that I've designed) from a machine shop for a few hundred bucks, and with an injection machine and a supply of some plastics, conceivably make a few thousands parts on a relatively short time scale, with minimal manual labor.

- iancmceachern 3y agoThank you for this! I just started exactly this! I bought a couple injection molding machines and started Golden Gate Molders. We injection mold parts right here in the SOMA neighborhood of San Francisco! Not only do we use traditional metal tools, we also provide 3d printed tooling options for lower volume prototype tools. www.goldengatemolders.com
- zonkerdonker 3y agoVery cool, just subscribed to your mailing list. As a mechanical design engineer, I'm a bit jealous! Good luck with your endeavor
