Can I print abrasive filaments on the UM3

Recommended Posts

I am on the verge of purchasing a UM3 but cant figure out if I can print some of the stronger filaments like matter hackers nylon x or any of the filaments with carbon added etc. I see they require a ss nozzle but I cant figure out with the new print heads if you can change just the nozzle to ss or not?

I am completely new so if this doesn't make sense, forgive me.

Anyone know?

You do not require a Stainless nozzle to print abrasive filaments, but if you use the UM3, the print cores do have brass nozzles and they will wear out pretty fast. And since you can not change the nozzle of the print core yourself, it will be pretty expensive to print abrasive filaments with the UM3, changing a few print cores per kilo printed if your material is really abrasive.

The stainless nozzles are actually only about 3 times as wear resistant as brass, and will still wear out pretty fast, i wore out a stainless nozzle in almost 1kg of material when testing, where the brass one lasted about 300g. (test was done with Colorfabb XT-CF20)

If you want to really print abrasives you should look at hardened steel or ruby tipped nozzles. None of these options are available for the UM3 at the moment though, right now the UM2+ is the better option for abrasives.

    • "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.
