ThermaX PEKK-C Filament, PEEK Alternative for 3D Printing by 3DXTech

[@michaelwhisman2479]

Haha, a great way to start the day. Reminds me of what one of my first bosses told me. "If you're not sweating you're not working and if you're not bleeding you're not working hard enough." Good times as always.

This stuff gives me an idea for an ablative rocket nozzle insert to prolong nozzle life. It turning to carbon is perfect because the carbon will act as a thermal barrier for the nozzle as its blown away. Save money on super high end metals like inconel and stellite, and just use regular stainless for the nozzle, then make the restriction in PEKK.

excellent insights 👌😎 I have to enter the High Temp Polymers level, the properties are incredible

[@yannismarle7797]

I've been watching this video and it occurs to me (maybe already used or tried) to test if sinking the peek piece into casting plaster to anneal the part but constraining it to it's dimension would be any effective, or is this just those kind of 1st ideas you have to let go away?

[@markthompson5983]

Hey the description shows hotend temps as 285-315

[@Sleepery22]

Yup, mistake. It should be: Extruder: 345-375 C Bed: 120-140 C

[@VisionMiner]

Good catch! We just corrected that in the description

[@cswagg]

@VisionMiner I was Sr. Lab Tech at Arkema for 4+ years and was HEAVILY involved in testing Kepstan (PEKK). Anyway, can I get a trial spool for my Bamboo Lab X1C?

[@pc7082]

Great explanations. Thanks !

[@awildridehome9469]

I could *probably* print this on a Qidi Q1 Pro. 350C nozzle, 120C bed temp, 60C heated chamber. It wouldn't exactly be perfect, but I might actually be able to print this filament on a printer CHEAPER THAN THE FILAMENT ITSELF.

When is PP-CF video coming? 🙏

[@VisionMiner]

Tomorrow ;)

[@volksbugly]

Over time if PEKK is sitting out in the sun could it crystalize and become stronger?

[@VisionMiner]

Highly unlikely, it needs to be at much higher temperatures to crystalize -- in the 200c+ range :)

[@cswagg]

no.. around 380 C for melt flow to occur to where it get's its strength by bonding. that and pressure would get you airplane wings made from plastic stronger than Al.

[@theburnner1187]

Do you think there are applications for high performance materials like this in the hobbyist space? If so, what would you use it for?

[@VisionMiner]

They're generally too expensive for the hobbiest space -- HOWEVER, there are many levels to hobbies :) For example, one of our long-time customers prints RC Jet Engine parts -- intakes, and the like -- works amazing for that in ULTEM 1010!

[@theburnner1187]

@@VisionMiner That's really cool. I think it would be awesome to see more high performance materials in consumer spaces. Thank you for your amazing videos!

[@princefpv1]

killer videos boys they are always great

[@StanEby1]

Very kühl. Learned a lot as always. Keep up the good work.

[@gregorylent]

cool, transcript attached! smart .. and an intro :-)

[@Gilmore304]

And space packing

[@Gilmore304]

That’s some nice space packing but it’s not necessarily appropriate for high tension mechanical properties. If you plan on using for testing then this would be a great way for multiple pieces to save $$. End result, go with PEEK after proto phase

[@gregorylent]

am i bleeding? not yet ! :-)

[@infernaldaedra]

I wouldn't be suprised if that was just PLA for the break tests lol. Obviously it isn't, pla would have melted like wax. But I'd be peeked if we could see direct comparisons between materials. Seriously VisionMiner: Don't 🐝 a 🐈! I don't know how you guys sell anything when you haven't shown real product data. This would help significantly with people finding the right material for their application. breaking small parts with your fingers isn't impressive and it literally only tells us the parts can break. Go big or go home & show real results. Print a knife blade or something and see if you can cut other materials with it, Print a drill powered gearbox and see how much torque you can get out if it with different materials. Print a 🔨 and drive nails. For scientific tests see already established methods below 👇 *Young's modulus* (Stiffness test) *Ultimate Tensile Strength Test* (UTS) *Charpy Impact Test* (V-Notch Test)(Impact resistance) Strain, Plastic Deformation, Stretch, Shear, & Yields. *ASTM D570/D5229* (Industry Standard Test Method for Water Absorption of Plastics) This is extremely important for the stability of the material considering water acts as a plasticizer in polymers and can lead to desorption or leaching of compounds from the polymer. Plastics also swell and shrink with humidity causing changes deforming the crystal structure over time & eventual degredation. *ASTM G99* (PIN-ON-DISC Mechanical Wear Resistance test) *ASTM F732 - 17* (Wear Resistance of polymers for Human Implantation and Prothesis) Electrical and Thermal Conductivity tests. That way you have a clear concise breakdown of differences between polymers and different suppliers.

[@VisionMiner]

This is the best comment, possibly ever. Thank you!! Totally agree -- would be good to have the materials lined up and test them one by one, Cole has wanted to do the gearbox test forever... and we recently printed a hammer in HTN CF25 and were driving nails at the Westec trade show last week :) :) All these tests are fantastic, if you're ever looking for a job, hit us up.... ;) Also, we get a lot of good feedback on these tests, probably because the data sheets have all the numbers -- and watching coupons break is more boring. That in mind, though, we DID build a custom UTM over the summer, and have yet to film testing with it -- but we're definitely aware we need to show both sides more :)

[@infernaldaedra]

@@VisionMiner That sounds awesome 👍 I'm actually totally onboard with that 😅

[@cswagg]

I know a lot about it

[@cswagg]

Moisture content needed to be less than 1% before it was good to go (ASTM D6304-A). What he broke looked to be at low temp heating and you could achieve the same self-adhesion to durability results by getting it into power form and putting it under 18 tons of pressure

[@steveh8724]

So I appreciate the content, but I really wish the presenter would tone down the ShamWow effect. I didn't come here to be entertained by forced theatrics. The kinds of people looking at this content, and considering purchase of these expensive filaments, are not looking for exciting fun content. We're looking for useful objective information. We're getting some, but not really enough given the resources available. In the comments on a prior video in this series the presenter promised they were developing methods to do actual quantitative testing instead of the 'two thumbs test' and the 'bend it in a vise' test. Countless other youtube channels feature reasonable quantitative measures of physical properties of 3D printed parts. Vision Miner needs to either up their game (as they claimed they were going to more than a year ago as I write this on 27-OCT-2022), or they should send samples to some other youtuber who is willing and able to do meaningful quantitative testing.

[@cswagg]

I've tested everything there is ti know about it
