Ultimaker 3 using 1.75mm filament

Recommended Posts



I would like to share with you how i make few updated on ultimaker3 to use 1.75mm filament with no more blocking inside hot end.

Before filament keeps blocking my hot (print coore) end event feeder was working fine, event original bowden is big enough.

So i left everything original no cuts no changes on printer itself. Only I add extra 2x3mm teflon tube inside print core to reduce that original hole. I put all way down as much as possible and left short end.


One more changes i did its in cura itself. changed filament settings for each core. go to machine settings>extruder

So if you really really want to print 1.75mm filament in an UM3 it's possible.  I don't recommend it but it's possible to get good results.  3dsolex will sell you a 1.75 version of the core.  I'll sell you this also in my store: thegr5store.com.  I have one customer who got it to work and work quite well.  He got it to work on both sides.  The right core is tricky because that one goes up and down.


Anyway contact me (even if you aren't in USA - I only sell to people in USA) for more details.  The solution is similar to above but the steel part inside the aluminum heat sink has a 2mm hole for the filament instead of 3.2mm hole.  The idea of putting bowden inside the "trumpet" as in the photo above is the same except to get it to work well we ran the inner bowden all the way from the core to the feeder.  The problem with this is that it's now harder to get the core in and out (have to remove the bowden each time).  But it works and it works well.

    • "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.
