Printing PEI - aeronautics-compliant material

Recommended Posts

Hello guys, I was wondering if any of you has ever tried printing PEI aka ULTEM which is a filament compliant with aeronautics standards... As far as I know it's developed by Stratasys and supplied with a diameter of 1.75mm. Is it available as 2.85mm for our UM? Any thoughts about this?

I agree that PEI is an outstanding material but I think there a few limitations to using PEI on at least my Ultimaker 2.

I print exclusively with 1.75 filament and to do that successfully I needed to make a few modifications to my printer. That said I looked into printing with PEI and found that my Ultimaker 2 printer is not within the specifications required for that material.

1. Ultimaker 2 extruder temp max is 260C and PEI would expect at least 330C

2. Ultimaker 2 heated bed max is 100C and PEI wants at least 110

3. Ultimaker 2 does not have heated enclosure but by adding a door you do get some desirable heat retention.

Aside from the expense of PEI limitation 1 is most likely the show stopper in my opinion.

    • "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.
