We have been making fenders from PET pop bottle for years. Learned it from Chuck Harris a re-purposing genius, RIP. They work great -- shaped to an existing metal fender with a heat gun, they are strong, flexible, light, very durable.
May make a how-to video for our winter cycling fashion show coming up, but for now I found this, tho it is pretty hokey: https://www.instructables.com/id/Bike-fenders-made-from- water-bottles-and-clothes-h/

I'm no expert on 3D printing, but from my minor experiences, this seems like a not entirely wise application of that technology... the objects you want are extremely basic and need some flexibility and structural integrity over a long curve. Rigid/brittle materials are not your friend here, nor is a bit-by-bit manufacturing process. It makes way more sense to extrude or stamp and shape fenders. (Why tho? What's the objective in making them yourselves? If the answer is "because it will be rad," then that's good enough too!)

I have a friend named Ian who will be available to answer questions about the work that he's done crafting bike parts with a 3D printer in "a couple of weeks" he says. I'll let you know :)

Anyone out there in ThinkTank land have experience with 3D printers and/or ever tried 3D print manufacturing of fenders with such technology? At Front Street Community Bike Works in Coos Bay, OR, we are considering ~$3,000 purchase of specialized tooling to make aluminum fenders. That is a very big investment for us. Then we learned about the potential of using 3D printing to make fenders. We have no experience with 3D printing but the idea intrigues me.
Here is a link to a design in "Thingiverse" (love that moniker!). https://www.thingiverse.com/thing:1695322/comments
Seems like the idea has potential and I wonder if it has been done with success anywhere.
