    PEEK Filament for FDM Printers

    INDMATEC, a German materials innovation company, says the introduction of all metal hot-end extruders capable of attaining temperatures up to 400 degrees centrigrade have made it possible for them to create a PEEK filament for FDM printing applications. PEEK material is tough, strong, and rigid. The material features strong resistance to hydrolysis, can withstand boiling water and superheated steam and has a density at least 5 time less than most technical metals. It can be used for parts which must withstand heavy mechanical loads and it's approved by the FDA for food contact applications. You can read the whole story here: http://3dprint.com/52713/indmatec-pe...nting-filament

    Below are some examples of objects 3D printed with PEEK on an FDM printer:

    It would help business to have a website in english.

    It will only be proffessional business if they maintain the ~600€/kg price...

    not to mention the hotend you need.
    But that is a ridiculous price.

    The price is, but isn't ridiculous in a way.
    As a specialist plastic that needs about 350*C+ to extrude, it appears to primarily based at business users, rather than hobbyists, such as those in the NDT sector of pipe inspection.

    And like most business', the first to do such a thing can pretty much charge what they want as they're the only ones who provide it; give it some time and as competitiors arise the price should drop.

    Also, assuming density is 1.32g/cm3 then it gives you about 6.2-6.3m of filament.

    I don't think it's terribly hard to get to those temperatures, you only have to think a tiny bit outside the current hobbyist 3D printer box. I've updated two different 3D printers to easily run at 400˚C with readily available sensors and hot ends.

    I doubt they have any intention of targeting hobbyist users for the short term though, but it's at least more available if you find a use that can justify the cost.

    My math places 200g of PEEK filament at 151.5cm^3. 0.024 cm^3 per cm, 6300cm of filament which makes it 63 meters, not 6.3 meters, with 1.75mm filament anyway.

    Was your new hotends calibrated for that high temperature?
    Are you using thermistance or thermocouple?

    I didn't do any calibration, though I did check it against a separate thermocouple meter.

    Specifically, I used a thermocouple on an E3D, and B3's 500˚C thermistor on a Pico.

    I posted this elsewhere, but...

    We printed this spiral vase in PEEK today on our Hyrel 3D System 30M with the MK1-350 print head, which prints at up to 400C and also prints with polycarbonate.





    That's the MK1-350 above the vase.

    Nice done. What did you do to make the PEEK stick to the buildplate?
