My UM2 conversion 1,75mm

Recommended Posts

How to improve print quality while avoiding the under-extrusion?

I converted my Ultimaker2 to the filaments from 1,75mm because it is easier to find them and more because they are available in very different materials that it is impossible to obtain with the filaments from 2,85mm, filaments that now almost no printers Production of business uses.

The problem is that I always have so little material in hotend my prints are under-extrusion.

How can I solve this problem?ritrazione.thumb.jpg.23e3b3e7205bec41f975921924fb11f5.jpg

    • "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.
