Thank you for your testing and research, I already use (Esun Pla+) on my printers, not as fast as the new ones but I will try the (eSUN ePLA-HF) to compare the printing quality.
@danieldeslandes2479 Thanks for the comment, yes I have quite a bit of their PLA+ also, I bought myself, and it can be a great balance of value and quality for a PLA. If you look back at my AMS troubleshooting video it was one of the recommended filament brands to avoid filament shredding in the feed. For me the main difference for ePLA-HF form the PLA+ filaments, although I did not do a direct comparison, is the reduced risk of print head jam. Not saying it will never jam, but should not jam on speeds up to 300mm/s. While I noticed no difference in properties of the filaments, if you won't be using it on a high speed printer, I am not sure you will get any advantage. Again, thanks for the comment and watching the video.
A potential with the print speed test is that, depending on extrusion width and height, speed might have gotten capped by the volume flow rate limit. For example, the filament profile shown (with 22 mm^3/s max flow rate) at a layer height of 0.2 mm and width of 0.42 mm will top out at 261 mm/s, so the anything higher than that on the tower will be capped at that speed, and obviously look the same. In this case, that's most of the speed tower.
@Dave_the_Dave Thanks for this, and yes, there are a lot of things where the speed will drop significantly depending on what is being printed, like overhangs.
You can certainly use compressed cardboard spools in your ams without these rings. I believe Bambu is referring to corrugated cardboard spools. I use Polyterra corrugated spools everyday for a business that requires rapid part production 5 days a week. Great video btw.
@grayfaux_ Thanks. Do you have any issues with dust from the cardboard? Honestly I haven't tried it because I wanted to avoid dust caused by the friction. But I would prefer to use cardboard to reduce plastic waste, and I could just hover out the AMS if it caused dust.
@T8Maker No, I haven't had any dust issues. Very little dust if any comes off a "good" spool. I suppose you could use a quick puff of compressed air between spools as an extra precaution.
Nice video I'm yet to try eSun maybe I will give it a try after the creality hyper pla. Only problem I have is you say default 300mm/s but thats very vague, like which parts of the benchy were printing at that speed? normally that would be internal but external walls dip to say half that so the print quality will be the same for all parts It is only time you would be saving over print quality or am I over thinking that?
@xXIamJAEXx Yes you are correct, its necessary to maintain quality. Honestly, unless your getting blockages or issues with flow, I wouldn't say its necessary. Anyway here are my settings which are based on eSun's recomendations. First layer： 50mm/s First Layer infill： 50mm/s Outer wall： 250mm/s Inner wall： 300mm/s Sparse infill： 300mm/s Internal solid infill： 250mm/s Top surface： 200mm/s Slow down for overhangs：ON Overhang speed： default (50mm/s in my tests) Bridge： 50mm/s Gap infill： 250mm/s
Its high flow filament so should give you a higher volumetric flow than normal PLA or PLA+. Should do some tests to see the difference between this HF PLA and PLA+ flow rates.
@TNotoriousAdam thanks for the comment, yes, you are right and I will probably test it at some point, but I don't want to become a filament reviewing channel, so if I do I might put it in a short. My next planned video is servicing my Bambu Lab printer. While I greased the lead screws recently, I used cheap lithium grease. Just got my hands on some Super Lube PTFE grease direct from the US, I want to try out, so I might do a full gut and clean and tighten up. See if that improves the prints. Then maybe do flow calibration tests with a few different filaments. Once that is done, need to do the same with the Prusa. As with everything, all I need now is to find the time to do it. Thanks again for watching the video and for the feedback, I hope it was of some use.
The audio is ok. The picture quality should be awesome but the camera focus and framing is meh, making the video quality above average but not as good as it could be (the bane of all recording) . The almost all natural lighting, colors and definition is what made this vid so much better than everything else I'm used to watch. Don't make my first statements fool you, your the best!
I almost never comment on videos and never comment twice. Especially when i haven't seen half the video but, this quality is what all of us 3d printing enthusiasts want to see for real visual test results. Thank you so much and please, everyone, like and subscribe to set the new standard we are all waiting for.
I got 1.65mm this year from eSUN ABS+ measured with a micrometer. Got massive extrusion problems with my Voron printer because it could not grip the filament reliable anymore in the extruder. Figured out a part was slightly melted inside the extruder assembly but 1.65mm surprised me… I still use eSUN because of the price and availability but I’m looking for alternatives.
@Todestelzer That is really bad, normally their filament is spec'd for +/- .03 so that is way out of spec. Did you reach out to them? The best for accuracy I have used is the Prusa Prusament, which is not bad value in Europe if you buy in bulk. But there are many other quality filaments out there, just price is an issue. There are many cheap ones that are terrible so its a bit of a gamble some times. Maybe some other views here can provide some recommendations, I would be keen to try others out too.
@@T8Maker im buying PC Blend and sometimes PETG from Prusa. I ordered ABS too. The ABS (ABS-T) comes in strange spools how are wider than normal and the Price is somewhat on the high side. And they charge for shipping even when buying over 100€ too. Lately they had PC blend for around 3 month not in the store anymore. Had to call off a customer to wait till i get the filament again. I could not change to a other brand because it was testet with other brands in a very hot environment and was the only good one. I didn't reach out to eSUN because of the filament. I don´t think they will do anything if you are not a big RU-vidr ;-)
@Todestelzer I am moving away from ABS, the fumes are too much, working on ASA now. But it has it plus and minuses. Generally most of the cheaper suppliers are not sold directly by the manufacturer, its a sales/marketing company. So even contacting the supplier will do nothing no matter who you are. But I always think its no harm to try, and who knows they might replace the filament, or at least if they get enough complaints they would feed it back to the factories. There are a few suppliers in Europe I haven't tried yet that might be better.
I tend to use nothing but high-speed filament. That is because we do a lot of prototyping and usually have about 4 or 5 machines running at a time, and the price is really not that much more than regular filament. I really think that all machines and all filaments should be high-speed compatible and get rid of all the old-fashioned printers to move the industry forward.
@qwertyzxaszc6323 I would agree except for one thing, for those starting out who cannot afford to swap machines, plus waste, there is a lot of waste in 3D printing, and junking old machines is more waste. That said there are a lot of great value high speed printers now.
@BackDaws you can print without them, but the friction of the cardboard on the plastic of the AMS can cause cardboard dust to build up, this could cause issues with the AMS over time. But if your having no issues, then less waste plastic.
@sshvulnerabilty Not sure comparing Carbon Fiber PLA against Carbon Fiber Nylon makes sense, since they are aimed at very different use cases, but maybe I can do something. Is this the one your referring to? www.esun3d.com/epla-cf-product/
Those measurements on your cube. Shouldn’t that be done at the tip of the caliper? Either way. I think most folks get the same measurements give or take as you. If I measure you you measured. My cube is 19.95x19.96x20.04 I recall reading that any tolerance less than 0.15 is considered good.
@alecubudulecu risk of measuring with the tip if the calipers is that you would not be flush and get off axis measurement. But after doing some maintenance, changing out the head I got much better numbers. But I agree, unless your doing high precision prints it doesn't matter.
@@T8Maker makes sense.. thank you for explaining. now that I think of it... based on what you just said... it shouldn't matter.... plus if I do it how you showed, I get flush. if I put the item flat where you did... and zero it there... shouldn't matter as THAT becomes the new measuring zero . thanks!
I see you use a Bambu printer. It would have been great for you to say how you feel the eSun compares to Bambu filament. No doubt Bambu filament is intended for high speeds also.
@georgemouer4565 I have not tried the Bambu Lab PLA filament outside of the sample half role that came with the printer. But it printed really nice and no issues with speed prints. Generally their filaments have been high quality, but their price matches others with similar quality. But you get the advantage if you have the AMS to have NFC work to tell the AMS what filament is installed.
@flat_stickproductions209 I have seen people say that too, but not sure how true it is. Thant said, most of the filaments you buy from Chinese companies, and some western companies, are made in the same factories as with many other things. but they may be made with different specifications, materials, and levels of quality, so its hard to tell. I have used both filaments, and the Bambu Lab branded filaments definitely produce better prints on the Bambu Lab printer, but that could also be related to tuning and settings in the software. But I also see Prusa filaments print really well on Bambu Lab printer with generic filament settings. I recently printer my Prusa MK4 upgrade parts on Bambu Lab with Prusa PETG and generic settings and they came out great.
@flat_stickproductions209 Great to hear it works well for you. You should check out eSun's website, they have settings for a lot of their filaments, to ensure your getting the best out of them.
Seems like a marketing ploy really. If you read esun’s documents and profiles for their other filaments the flow is high and the recommended speeds are high too. I don’t have any issues printing their PETG at 200mm/s or PLA+ and default Bambulab profile speeds.
@justinfielding I know where your coming from, I have not had any issues with printing standard PLA at high speeds. But the pitch is that is reduces the potential risks of high speed printing, like clogging. So if that is a problem your having, this might be the solution. But if your not, then no need to get it. But this goes back to the old 3D Printing issue, there are so many variables that affect your print, that there can be no one size fixes all solution.
