There is actually a very simple solution with a counterintuitive trick. When you use the packing tape, set the print bed temp to 0 yes ZERO not 90 or 100. The heat loosens the glue (on the tapes) sticking strength. Tape will stick perfectly during the print and the shrinkage of PP is not as much as you would think if the part being printed does not have sharp corners ,or does not have a large surface contact with the print bed (Any shell shaped components print perfect). I have been printing without any problems for years. I also printed fiber reinforced PP and that prints perfect.

Came back just to say: thanks a lot for the packing tape tip. PP straight up FUSES to it!!! Works like a charm! Thanks!

Magigoo is amazing. When my beds failed to heat this glue came in and saved the day even at near freezing temperatures

Thank you for covering this, I love the properties of polypropylene and want to master printing with it! One thing I found that helped on my Artillery Sidewinder was to drop the bed temp to 70°C, it seemed like at higher temps the adhesive on the tape gets soft and let's the part pull it up off the bed too easily. Best of luck!

Great video! I'm new to 3D printing, so trying to learn everything I can. Your content was well presented and clearly explained. Liked and subscribed.

It was probably the glue on the tape that released when it was heated.

Another great video, very helpful.

Just clicked onto the video, but I’m super excited to watch a video about a different material. I’ve really been enjoying your channel! Keep doing what you’re doing!!!!!!

Interesting material👍 Great video as always Thanks for sharing👍😀

Great Video ! i just ordered a small sample of Polyrplene off of Aliexpress just to check out this material.I have also heard that the best way to print this material would be to able to print on a 3mm thick PP sheet. You could probably try that out and print longer without bed adhesion issues.

Whoaa looks amazing. Just got my printer working with tpu using a bontech direct setup with e3d v6. That alone was such a mountain so im gonna print here for a while but im gonna get some of this stuff. Great video keep going bro!

Great video! Thanks for the information.

Try cutting off an even layer of a PET bottle and using it as a 3D printer table cover. Pet and polypropylene can be printed on top of each other, but with little effort they usually come apart. At 100*C - 180*C, the PET substrate should not melt or deform. When the table cools down, the part can be torn off. Попробуй обрезать ровный слой бутылки из пэт и использовать её в качестве покрытия для стола 3д принтера . Пэт и полипропилен могут печататься друг на друге , но при небольшом усилии обычно рассоединяются . При 100*С - 180*С подложка из пэт не должна расплавиться и деформироваться . При остывании стола деталь можно оторвать . Another option is to try reinforced window film, they are sold separately. I somehow tried to heat it with a hair dryer at 230 * C - she didn’t want to sit down at all !!! Ешё вариант - попробуй армированную плёнку для окон , они продаются отдельно . Я как - то пробовал её греть феном при 230*С - она усаживаться совсем не хотела !!! Есть ещё вариант kzfaq.info/get/bejne/pdeapdyY386-m58.html

Awesome channel man!!

Awesome video! Been printing a bit with polypropylene (fiberlogy black pp). Love the smooth matte surface finish it gives and that soft to touch feeling like car interior parts. You have covered all but in my opinion the glue on the tape you are using isn't strong enough and that's why your part is warping. I've used 80°C for bed with cheap tape and it did fuse to the tape and made it imposible to remove the bits of the tape from the print, now i gave it a go at 55-60°C and the prints do not fuse to the tape. Also i'm printing with 60/30mms 20mm first layer, brim or raft if it's tiny contact area, fan 100% above 6th layer or so. Retractions are the same i use for pla.

Very cool video my man

ive seen folks with dual extruders lay down a .2mm layer of tpu then print PP on top and it eliminates the need for the tape and warps a lot less. BTW have you tried to post process the PP to make it clear ?

Brilliant content must try

I like that brand, they make good filaments !

You should use tree supports and float your models in the slicer to make a very small/sparse bed contact.

yes it warps very well. presumably shrinking quite a bit when solidifying. maybe since it's partially crystalline. One big flat object lifted in the corner from the Anycubic ultrabase/packing tape. I read some packing tape melts so I didn't want to go too hot. Using a raft, it would stick, but does not detach cleanly. With a brim, it forms a smooth shiny surface on the base. One tip I saw in a paper on fluidics was printing with 110% flow for no leaks. They used polypropylene interior part to be in contact with fluid channel and PLA from a second extruder outside to form threaded fittings. Too bad I don't have dual extruder setup. The tip here using small contact area should help a lot with warping. Smaller parts are better.

Print polypropylene easily. Glass or aluminum or steel bed with Zillagrip coating glue allows you to print the most type of plastics and works with a cold bed. Just heat the bed to release. PLA ABS Nylon PETG PP POM PC with one glue coating adhesive.

Polypropylene is the lightest filament as well

Great video I would like to see you print HDPE or hemp filament,and perhaps try using a pellet extruder to print recycled plastic. Thanks for taking the time to share your findings,a true scientist.

Thank you!

Merci pour l’info

Regarding your exploration of materials, do you have some experience with food safe materials? Like the ones one could use for instance inside water well or pump

Have you tried sugar water for bed adhesion for me it does wonders works with abs pla petg pet tpu. Here is how you do it 100ml of water in a bottle or cup mix until dissolved 1 or 2 table spoons of sugar. Use a painting brush to spread on heat bed then heat the bed to 60 - 70 degrees C wait until the water has evaporated and the bed is sticky like wet candy start printing.

This stuff should be very hard to print, nice vídeo.

Nice video. Was the bottle water tight?

Hey Chris!

What retraction settings do you recommend when printing polypropylene with a bowden tube? (Ender-3 v2 neo)

You used the tape method! :D

Hiwnis it for VOCs and toxicity when printi g, in comparison to PLA and PETG?

🔥👍

What cura profile do you use for you Genius printer?

My tape was pulling up on my ender bed when it warped, So I flipped the metal sheet over and stuck the tape on the metal side and it stopped coming up. I find having the super hot bed 90 degrees works better than at 60 degrees

How about the strength between layers?

Did you try using a Raft? It might be good way to avoid part warping

What about using a polypropylene build plate?

Does this filament print well on a ender 3 v2? Or any other printer with a bowden system?

What about the fumes? Any harmful fumes?

Sir, how much is your "Artillery" 3D printer?

I wonder to know if I could 10Litre 2 layer water galon

Доброго. Актуально.Доходчиво.Спасибо за труд.Удачи!

I hope someone sees this or can help me but I've been trying to print pp on my creality cr10 smart and oh my God I'm on the struggle bus bad adhesion I've spaghettied its been all over the place and I'm desperate for help

This guy looks like the corporate boss from Avatar

Maybe you should have printed with a Raft

"It's also resistant to a wide range of chemicals including WATER" yes that is the impressive thing, not its hydrofluoric acid resistance!

not showing any squeezing or throwing :\

I'm thinking a carbon fiber version would be perfect for 3d printed guns.

Geez I waited the whole time for you to say pee pee and make a joke about it but it looks like you tried your best to avoid saying it 😭

stop touching your nose
