PEKK: PEEK's younger, stronger, faster sibling. Also known as "Antero" from Stratasys
More Info: visionminer.com...
PEKK is much like PEEK in performance -- temperature resistance, chemical resistance, and strength -- but it's about 10x easier to print.
PEKK (PolyEtherKetoneKetone) is one of the highest-performance polymers in world. A leading material in the PAEK family, PEKK has exceptional mechanical, thermal, and chemical resistance properties, while being substantially easier to print than PEEK. Developed in partnership with Arkema - a leading supplier of ultra-performance materials.
ThermaX™ PEKK product attributes include:
-Substantially easier to print than PEEK
-Glass Transition Temp (Tg) of 162°C (20°C higher than PEEK)
-Melt Temp (Tm) of 335°C (allows for lower print temps than PEEK)
-Inherent flame resistance (UL94 V-0)
-Low smoke generation for aerospace applications
-Outstanding mechanical, thermal, and chemical resistance
-Continuous Use Temperature (CUT) of 260°C, higher for short durations
-Excellent resistance to a broad range of chemicals, such as those used in the oil/gas, automotive, aerospace, industrial, and chemical processing industries
Gone are the days when you needed a wildly expensive closed-source printer and license to take advantage of ultra-performance polymers. Our PEKK was created to be printed using the many new open-source printer platforms currently available on the market. Compare to Stratasys® Antero™ PEKK and you will realize this is a great opportunity to take advanced of an aerospace-grade material without being tied to an expensive closed-source system. 3DXTech® and Stratasys® both purchase PEKK resin from the same supplier, so what's the difference? Freedom, cost, and innovation. ThermaX™ PEKK can be printed on a growing array of lower-cost printers whereas the Stratasys Antero™ PEKK requires users to purchase an expensive Fortus® system and a high-priced license.
ThermaX™ PEKK has a wider processing window than PEEK and typically prints with extruder temps between 340 - 360°C, whereas PEEK often requires extruder temps of 400°C or higher. ThermaX™ PEKK has a lower rate and degree of crystallinity than PEEK, which aids in its ease of printing. However, once printed and annealed, PEKK parts exhibit superior performance vs. PEEK. Easier to print + superior performance!

@ChristianDybdahlXTR 3 года назад

Both PEEK and PEKK are semi crystalline in structure when below GTT. Also the more annealing you're doing the smaller the part becomes.

@AshGreen359 6 месяцев назад

If only I was capable of reprogramming the print to accommodate annealing shrinkage

@AshGreen359 6 месяцев назад

Does it come in carbon fiber?

@Dr.Alchemist 4 года назад

Something not clarified in the video: when amorphous, the PEKK will be translucent, while when semi-crystalline it is opaque. And the semi-crystallinity has a melting point (Tm) which is also a factor, not just a Tg. Technically all semi-crystalline polymers can be amorphous if you inhibit the crystallinity from forming. Over time, though, even an amorphous print will eventually develop that crystallization. It should also be noted that defining what is "better" between PEEK and PEKK will absolutely be application-based and not just determined by the material data sheets. Last comment, PEKK may be a little easier to print, but that doesn't automatically make it better than PEEK. PEEK can also be printed amorphous with the right active cooling/ambient temperatures and that will provide some interesting potential benefits over printing it as semi-crystalline (or annealing it). PEKK is a sweet filament and I agree with the video that it's easier to print. It does actually respond really well to being printed with active cooling or an unheated print chamber as compared to PEEK.

@VisionMiner 4 года назад

Spot on, excellent points! We do brush over the different looks of the material in it's different states.... but didn't go too deep. And yep -- it totally, in actuality, depends on the part application :) Excellent comments, thank you!

@Dr.Alchemist 4 года назад

@@VisionMiner Yeah, my original intent to comment was to clarify exactly the difference and not just by the color differences. I suppose there could be an entire materials science lecture thrown in here somewhere to further explain why crystalline materials are opaque while amorphous ones are translucent, haha. Side comment: your nano adhesive + using a glass print bed were absolute game changers for my custom high temp printer. I would highly recommend that anyone looking to print PEEK, PEKK, PPSU, PEI, etc. use the nano adhesive.

@sixdegrees6434 4 года назад

Is there a substantial dimensional change when annealing and if so, is it the same % of shrinkage each time given identical annealing treatment? I am interested in this but i'd like to know if I can reliably print and anneal to at least 0.2mm - 0.4mm accuracy. Love watching you guys geek out on new materials. I feel good knowing i'm not the only one ;)

@VisionMiner 4 года назад

Hah! Cheers. So, yes -- but it depends on the geometry and each part will be a bit different. That being said, with a few tests, you do get consistency -- so to answer your question, yes you can print reliably and consistently and anneal within that accuracy. This stuff is so cool, lol :)

@turbomega 3 года назад

I have now tested a lot of filaments (PEI, PEEK natural and with CF and fibreglass) The video says PEKK is the fix for PEEK. And I printed PEKK-C parts (no fibres) with decent result. But after post heating/annealing (160C and then 200C), the parts warped far beyond the usable shape. Do you have any tips to avoid this? This is not what I expected. The nartural PEEK-parts are a lot better, so how the PEKK could be a fix for PEEK, I can not understand. Is it better to shock heat the parts? So the surface can crystallise while the inner part is still rigid? And when the inner part heats up, the outer part is a bit rigid and holds the shape? Or the totally opposite? Frustrated..

What is the reason for the high price?

@VisionMiner 4 года назад

New polymer, expensive to make, rare and only used in high-budget applications like aerospace :)

@WhenDoesTheVideoActuallyStart 3 года назад

I bet half of the price is because of patents, and if there was more competition some company would have already figured out ways to more reliably scale production. How can someone patent a molecule?

@Tedlasman 4 года назад

How do you price out printing in peek or pekk for clients?

@VisionMiner 4 года назад

We generally charge the same, but sometimes a bit less for PEKK, especially on big parts, since the chance of success is much higher.

@Tedlasman 4 года назад

@@VisionMiner I mean, how do you price exotics and high temp stuff in general, compared to things like pla, abs, and Asa?

@VisionMiner 4 года назад

Simple: we don't print basic materials at all. PLA/ABS etc are too cheap at this point, and already on the market to do well, without a large volume print farm doing hundreds of jobs per day. We focus on more difficult, specialty prints, with one-on-one relationships with the service customers, since generally getting a good part out is more challenging and complex -- often, a print job turns into a design consultation, resulting in a better, stronger, more aesthetic part :)

@VisionMiner 4 года назад

On that note, our prices are not cheap, by any means -- but they're always better than the alternative manufacturing methods :)

@ZhuJo99 3 года назад

It's not about hotend temp, which you can upgrade pretty easily even on cheap chinese printer to print at 450 °C. It's about heated chamber (better at 120 °C upwards, 160 °C - 250 °C ideally). And obviously, high temp bed (140 °C upwards, ideally at 200 °C). And that is something you will never ever get without specialty things like extruder motors out of the chamber, shielded and high temp rails and belts (ideally no belts), heaters in the chamber (powerful one, and good heat distribution for even temps), strong insulation etc. Also, these materials are extremely hygroscopic, so drying for a long time (6 hours at 120 °C) and having heated filament chamber too (to prevent moisture absorbtion during printing) is absolutely neccessary. All in all, you will not do that without proper (and expensive) equipment. Even basic Funmat HT with it's 90 °C chamber will have a hard time to use these materials for bigger objects and lot of tuning.

@tuannguyen2253 2 года назад

which is better, PEI or PEEK? GUYS

@VisionMiner 2 года назад

Depends on the application, but generally PEEK has higher resistances in the thermal/chemical/ strength categories due to it's crystalline structure. Much harder to print though!

@g.4279 2 года назад

How much dimensional accuracy is lost during the annealing process? I know annealed PLA is pretty infamous for shrinkage in one dimension and expansion in the other two, even when packed in salt.

@elijah_9392 2 года назад

Other way around. X and Y shrink, Z grows.

@kambizchizari8556 3 года назад

Well, I think the Continuous Use Temperature (CUT) of the printed PEEK is much higher than PEKK, other than the price advantage, no? And also if you add post-processing, then it is the higher cost of PEKK plus the cost of the post-processing and its complications.
