rubber materal?

Recommended Posts

so i'm making a prototype for a product that will be exposed to weather. and i was wandering if there is a materal that is ruber-like to make gaskets?

i am aware i will have to treat the product itself and that normal objects 3d printed are NOT waterproof but this is just a concept model. is there such a material that anyone is aware of?

Take a look at the flexible materials thread, a lot of those can be used for gaskets. Why would normal 3D printing not be waterproof? A print with good fill and 3-4 lines of thickness should be able to contain or block water pretty good, even less when everything is tuned right.

there is FilaFlex, flexible PLA, Ninja Flex and Form Futura Flex Pla and Probably others

they are difficult to print with. some near on impossible to get a really nice print every time on an UM2.

maybe. but nothing i would trust outdoors for years on end.

 

Most plastics are rubbish for years on end outside without some special form of UV protection or other coatings, so I guess you are right there. If you want high quality and control over the end product, I would suggest you look at casting some (often polyurethane) gaskets. You can get a lot of different types and grades of that with probably more uniform and tweakable results when it comes to the material.

If it is just a concept model then it might not be too relevant yet to have an actual durability of multiple years. Something like the flexible filaments will do in that case - it would be interesting to see how long it actually takes them to fail.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
