3D Printed Fuel Tank?

So there is this place in my town that offers a full service bike shop, wood shop, audio & video studios, and a computer & robotics lab. Full access for 35 bucks a month membership. They have a few different 3D printers and one of them prints in a resin of some sort. I did a search and didn't come up with anything so I was wondering if people have tried printing gas tanks and what material type should be used for best results. I guess it would have to be flexible so it dents and not crack...

What problem are you trying to solve with metal gas tanks by going custom?

Oh just the problem of having an awesome 3D printer available and needing something cool and maybe original to make with it. Also, I've seen vids on threads on how people make custom fuel tanks with sheet. I was thinking of building a four stroke cruiser style and the possibility of having a 3D printed in frame mounted tank would be pretty neat. Just thinking right now. I guess it would really depend on the material. You could even print the mounting brackets right into it... idunno just a random thought on a random night.

Depending on the design it would need to be made in 2 halves or w/a lid on it. Then you'd need to figure out how to put the 2 pieces together. Plus filler cap.

I think it's a cool idea. If the printer can use a material strong enough to hold up to mounting and fuel proof you could really have something here. The bung and tank could be all 1 piece with the threads on the bung and a cap to match. The area for mounting and the petcock could be beefed up with threads in the bottom of the tank. Probably need to be really beefed up for a lot of threads at the mounts. You would want to thread the petcock for a normal motorized bike petcock for ease of finding replacement parts.

I was thinking that if i wanted it to wrap around the tube you can just make it C shaped as well

Draw something simple and similar size in 3d then get a quote; printed in hdpe at least 2.5mm thick. And let us know what it costs.
