Hi Igor, how far from the humble beginnings 3D Printing already moved away! Not only a huge menu of colors, but now we also have shiny, matte, rainbow, multicolor… and now “FAST” filament ❤

Great work as always Igor. I like the idea of non-petroleum based spools so not keen on plastic. Printed rings have worked well for me The manufacturer's could consider spools with plastic rims, or their own design of ring that clupsxsecurely in the filament retaining holes in the spool Or look for user designs that use those holes to make the ring as secure as possible. I tried "Hydra" style universal rings but they just didn't rotate back when the AMS rewound the spool so I went back to printed rings, of which I have a selection for different manufacturers.

Great video professor Igor, I think it would be great to re-do these tests with a bambu lab printer. Not so much the same filaments but to test how the speed affects the strenght of the part.

Regarding eSUN cardboard spools. You can tear the sides of the spool off and put the filament with the cardboard core on the original bambulab spool. Takes one minute to do, works perfectly fine. The inner core in eSUN spool even has the same cutout ;)

Use painters tape and wrap the spool then tear of one edge at a time and place it on a reusable bambu spool. There is a gap that will fit the notch on bambu spool. It works out perfectly or you can 3d print edges for the cardboard spools.

Great video Igor! Just put a layer of electric tape or scotch tape at the edge of the cardboard spool and it works with the bambu ams, usually it's not a big issue in my case.

Yet another great video, Igor! Love your detailed analysis as always. Not related to this video but just a humble idea/request for an upcoming video: Could you do a test on best allround nozzles currently available? I have a Prusa XL (2 tool heads) and I've been considering which nozzle to upgrade to. Something that I could install and forget about no matter what filament I want to use. Something that can withstand all kind of filaments while also having great thermal conductivity. The best options seem to be full body tungsten carbide nozzles and then there is those very promising diamondback nozzles that even require you to lower to print temperature because they are so heat conductive. I would love to see a round up test done by you because you have pretty much the best in-depth comparisons on YT.

Recently ordered some white esun pla from amazon. Was very disappointed when the spool arrived half empty and not in a sealed bag. Amazon refunded me the full amount and let me keep the half roll. I dried what was left and the print came out really good. Just wish my first experience with esun wasn't what it was

great video thanks - I use esun pla plus for my surfboard fins - work really well unless you leave them in the car for a few weeks over summer, then they tend to break in the surf. On cardboard spools .. I read that they absorb moisture a lot easier , and perhaps transfer that h20 to the filament, . will try the pla plus at 240 (on ender 3 v3) , good idea, thanks.

Hello, It is very interesting video. I am curios what will be with 230 and 240 deg without change any thing else...

hello, ive been watching some of your filament reviews and love the testing. ive recently bought some Eryone standard PLA and the white and silver that ive tried so far will not print well at all on my X1C. the first layer seems to be the most difficult to get down without adhesion, warping, blobbing, and small bits of extruded filament hanging out of the nozzle even after the cleaning cycle. theyve offered to replace them but ive bought 10 reels of different colours and dont really want another 10 reels of misery. have you tested there other filaments? are any ones better like PLA+ or Matte?

Interesting videos and love the different test methods. How fast is the Kingroon able to print? I don't think that the 100 mm/s is anything compared to the new breed of core x/y printers from Creality and Bambu that can print at speed from 300-500 mm/s. Not being critical of your video at all but just don't think the new speed filaments are made for this printer but rather the much higher speeds.

Great work!

thank you

Too much cooling coud produce delaminations , (too much is my setup, i got two 5015 fans runing) , i use 30-40% fan power, but for the Creality i print some parts at 100% fans, no problems, for me

Did esun also change the grey color of pla hs?

Maybe Esun should sell its fast filament ready to go onto the spare bambu spool!

Wow , i got the same silicon surface yuo put in the oven, funny😊

hello Igor...which would be the best filament for making a knifeblade and get it as sharp as possible? polycarbonate maybe?

I was printing with Creality white Petg , very good , and then i change to this ones petg esun white hs and was not good at all , sooo i think is just propaganda Remeber , they want to sell, for me normal creality petg (white) was very good, printing big pices at 150mms@10.000 mm/s2 using klipper/bmg/volcano setup in a modified ender3, good luck😊

Odd video. You're not testing the filaments correctly at the start because your printer isn't set up right. I would've started the whole project/testing again from that point.
