Ziogianni84 3 Posted November 26, 2017 in Printing PEI - aeronautics-compliant material (edited) 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?

1-prop-head 1 Posted November 30, 2017 in Printing PEI - aeronautics-compliant material 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.
