filament diameter compatibility

Recommended Posts

Hi community

Hope this isn't a stupid question, but I didn't find anything on that matter:

Can the UM handle 1.75mm filament? I keep reading that there are filaments that are too thick because of bad tolerances, but how about too small diameters?

Maybe the stuff gets curled up inside the bowden tube, or maybe it just fits perfectly?

I'm asking because I'm interested in buying some "Aurora" filament from faberdashery, but they only have that in 1.75mm diameter...

Also (probably) a nozzle, teflon tube, peek, brass tube all made for 1.75mm filament.

The simplest/most effective way to switch would probably be to purchase an E3D hotend that's made for 1.75 filament, and have two print heads that you switch between when you want to print in different filament diameter - assembly of the stock UM printhead is a pain in the ass, because the tightness of the thumbscrews affects the nozzle location so much, and the wire routing is challenging.

I suspect in this setup, you could probably keep the 3.0mm bowden tube.

    • "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.
