3D Printing with PEEK (PEKK) Filament at 360C! 

buying a filament 40 times the price of normal filament, and then printing at 700 degrees in a wooden (WOODEN!) 3d printer in the middle of your living room in order to make escher pancakes? FUCK YEA!

You used 200 euro filament to make pancake artwork *Subs*

My ender 3 is about to catch fire just watching this

This was great! SUBBED.

Awesome, great to see average people like us working with high end filaments for the sole purpose of education, knowledge and entertainment. Two thumbs up. Thank you.

Alexa is becoming more human than most humans I know. That filament is impressive, I thought you were crazy for wanting to print at those temps but now I see the potential. You could potentially 3D print working engines and rocket nozzles among other things. I'm also impressed with your cooling solution.

Among the things I never thought I might see on RU-vid: tesselated pancakes... Brilliant! Subscibed. Clyde

Thanks for sharing this crazy test!

Oh buddy, what a great video. The pacing of information about what you are planning to do was excellent. I was sitting on the edge of my seat watching more because I was like wtf is this guy doing with a heat resistant lizard frame. then you just kept making cakes and it was like, any reasonable person would have stopped after the third one considering how hard demolding is. then a big reveal at the end. really a great video!

THIS IS SO GOOD! I've linked it from my channel. You do great work. I hope your channel takes off!

I love this video so much

What a super fun project .. well done sir!! I had some Escher posters in my dorm room.

I LOVE HOW YOU ROLL.

I liked this video and subscribed because of your "Appropriate PPE" 🤣🤣🤣

Man I love this.. your are gonna be the one to watch for 2019 best 3d printing related video I’ve watched this year

Epic lizard pancake art with epic music. Subbed and Belled.

Subscribed purely for the humor factor. Good presenter.

loved your presentation haha

I need this level of dry humor in my life 😂

Best vids on youtube 👍

first video..instantly subbed lol

Nowadays the average user has problems printing PLA... and here's my dude printing one of the most expensive filament, PEKK, in a wooden printer, in the living room, to make a form for pancakes... Sounds like Mega Chad potential to me ngl

You're funny!! Definitely subscribing for more of this

Great video!

You could print lead with that Nozzle… Great Video

For the cooking, you'll probably need to use a foundry mold trick. First sand all the inner edges to make them smooth to help the pieces not grab the sides. Then, add a slight bevel so they pop out a bit easier :)

hilarious :D good job!

Edible Escher, tasty tessellations, subscribed.

quite rare to see people printing peek and other high temp plastics on yt. other than the vision miner channel that builds comerciel printers. really good video

Lol best intro

Your voice and sense of humor remind me of This Old Tony...

Entertaining :D

The hell did I just watch?? SUBSCRIBED!

Hi 0Calvin, I have gathered some experience printing PPSU, which is similar to PEEK and PEKK but extrudes at 400°C. Let me give you some advice, what I found was that a hot air fan set at 220° and directed at the print as a print cooling fan gives very good results. You basically need to have the "ambient" above the heat deflection, but under the glass transition temperature. It works so well, that you do not even need a brim. Secondly, you need to dry the filament. This is extremely important. My PPSU comes on a metal spool and needs to dry at 150°C. I went so far as to have it in the oven directly next to the printer and use the freshly dried filament, it results in excellent and very translucent prints. From your print it looks like you have a lot of moisture in the filament. If you are interested, i have a thread on reprap.org. Cheers Max

i've never annealed PEEK but i found to prevent pla from changing shape when annealing i fill/surround it with some fine sand, makes it take a lot longer though and you have to kind of guess when its ready

You forgot the gloves, elbow, and shin pads on the safety gear. That was a nice touch

You are right, totally worth it xddd

You print much better than you cook :)

Cool video man. Next time put your pancake mix in a ziploc and cut a small hole at the tip. Then u can just pipe your mix in there. Might be easier for ya.

I totally enjoy your videos. Hillarious! Are these special heater cartridges from e3d like in the standard v6 or the hight temp versions from them? Btw. awesome t-shirt! Also a moist spongy painters roll helps me to achieve a very even and lovely thin layer of pva glue on the print bed without bubbles. Cheers!

What heater cartridge and hot end did you use in here?

Thanks for share, nice video.... I'm hungry now!! with your printer are you able to print almost anithing? Which book did you mention?

Printing C4 next-;)

I came across 5 500g spools of essentium PEEK 2.85mm filament for $20 at an auction. I’ve been slowly selling it on my eBay page for about half of retail

Nice video. No offense, I think next time you should try 3d print pancakes :P

congrats!!! you made a $200 pancake!!!

Hey, Chef your batter is a bit too thick. But, really an interesting vid. Thx. :)

PEEK by general use inject mold manufacturing ?

Quite enjoyed this lovely video, already subscribed to your channel, so could do nothing else but buy a book from you ;-) Done so, but now I have a book to read on my phone (used google books). Is there a way to get a book as an epub for reading on my Kobo eReader (no, not a Kindle)? Keep on doing these nice video's, All the best, Ruud

that is very nice can you also print a hotend or parts of a hotend? Greetings from Germany.😃

What nozzle did you use? I have the microswiss but most it can do is 300 so I'm upgrading that.

what are you using for that thermal camera off you cell phone?

I'm interested in that IR Camera that plugs in to a Cell Phone. Where did you get it & what is the make & model?

Lol. 10:47 - " I see no smoke or flames." Literally 2 seconds before it was smoking. Awesome material though.

have you tried annealing on the glass plate?

Wow, interesting design of the mould Well done. Next time, mayby the mould should have some 15 degrees slope, and some oil, as a release agent ;-)

Nice. I thought it were only expensive high-end 3D Printers able to print PEEK because of the high temperature the nozzle require. But I guess your older Ultimaker could do that (even thou it needed perhaps a bit more precision to be more flat, and not slightly bend).... Cool. BTW: The software you are using to get the nozzle temp to 360 degrees, are that just standard software that came with the Ultimaker?

Hello What Thermistor and Heater you need from so high themperature?

Do you know how peek producing

Which foil was used to insulate the printer?

Very interesting. I don't think I will ever print at such an extreme temperature. If the objective was to make Escher lizard pancakes, you could have print a PLA cookie cutter. Do you have any project for the rest of the spool?

Money well spent!

Is that Kapton tape? What kind?

20:43 lol we thought the same thing

Windows XP!

next time with vanilla and fresh coconut.

Would you happen to offer custom 3d PEEK printing?

Is PEKK foodsafe?

Wait you only wrapped the sides? The top is probably the most important side

"the plastic is handeling it better than my pink fleshy hands" YOUR FLESH BETRAYS YOU BROTHER!

@3:12 You're only half done, you also need to practice screaming and flailing :)

You Monster eating those poor fractal lizards

Smoke above hot end at 287C

Well that was kinda usless Alexa

Is pekk food safe? Otherwise great video. I had not idea that the old ultimakers could be capable of this even with upgrades.

I have heard that printing with PEEK is very dangerous because of the fumes that leave the plastic while printing. I don't know if an open printer without ventilation is the perfect place to print with PEEK.

A safer and cheaper approach would be to print a mold of the pancake mold out of whatever's cheap, and use it to cast the pancake mold out of cookware silicone. Might have to alter the design slightly to compensate for the floppiness of silicone, but food would release easily and you would be using a material that's considered safe for cooking.

Is it food safe?

Pretty expensive mold

you soo could be on mystery science theater 3000

If you have kids... this is cool... If not... This is creepy... Lol.. JK man... I liked your video.

This video was informative but those dissolve cuts hurt my eyes every time. Thanks for the upload!

Relax I print filament in the 300 range all the time it's not a big deal. By the way you don't need a water cooled system for that . Just all metal hotend . The filament you got there is very interesting. I'm going to look into it.

0/10 no 3d benchy. Much disappoint

Engineer humor,.. oh my

FDA? Just askin'.

The hot pan test isn't really a fair test since you didn't anneal the other filament, such as the polycarbonate. I'd love to see a comparison of the 2 filaments, PEKK & PC after both are annealed.

All this for a pancake lmao. Just order pancake stencils from Amazon smh.

Geezus, is that filament laced with cocaine? Why is it so expensive...

Cool experiment, but for your application I think you'd have been printing a gecko cookie cutter, and using PLA or something.

You're off-gassing formaldehyde from your pan by having it sit at 500F with nothing in it.

10:27 smokk

why don't you just make the pancake and then use the mold to cut out the shape after? I guess that defeats the purpose of needing pekk, you could just use pla at that point.

its wierd how he calls us kids

Well.. a 200$ pancake :)

Why not use a pliers? lol save your skin
