printing with polyurethane

Recommended Posts

Hard to help you, all i can say is for UM Flexible filaments print at 230°c the trick is to have the most constant speed all the way long, so i print everything at 30mm/s (even the first layer).

Check if the feeder is not jammed with the filament, it happens often that flexible filament goes in every path possible (it helps having IRobertI's feeder from youmagine with the filament guide.

it really depends on the type of polyurethane. There are thermosetting polyurethanes which do not melt but only decompose. I would be really careful heating up unknown material, as these polymers can have dangerous decomposition products

Have you checked that the material enters the nozzle properly and is not stuck on the edge of the white thermocoupler? I had that issue sometimes when printing with FilaFlex.

Also oiling the material a little bit also helps witht the feeding. For me the friction got too big but only after the material being fed almost completely into the nozzle.

    • "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.
