I'd expect E3d, Prusa, Slice, and other big names to have similar info. But it's awesome to see it published on the internet. Collecting and publishing good data like this is a TON of work.

@@martylawson1638 Not neccessarily. Printing speeds of around 60mm/s has been around for a long time and focus typically would be on part cost and manufacturability. And research is non linear. Any progress and open data made here will be a big boon for the companies to produce the type of filaments and print heads suitable for fast printing. The creation of a datum like this would help all the companies and the industry. Ultimately us as consumers. Also reminds me that 3D printing has a lot of potential areas to grow forwards.

Good point. I am not familiar with the process. Will look into it.

me too

Thanks man! glad you enjoyed!

Thank you very much!

Thank you for your comment! yes indeed, a lot of work. At some point I feel I only see the glitches and the mistakes. I am glad to hear that it still makes some sense 🙂

Thank you 😊

Thank you!

Enjoy

Not impossible, just tedious. I fee the data is worth the effort. Also basic data can be done by then, but it can also be crowd sourced (ie Have a list of parameters to try / components +nozzles etc to be tried and have people submit data if they do so, maybe even make it a competition a al “#SpeedBoatRace” / “Speed Benchies” etc. Also the semi-automated nature of 3D Printers, and potentially jigs/automated scanning+photogrammetry etc could make the data collection easier, even for a single person. (Edit: Readability Improvement)

Agreed. What I think we need to do is to define a standard for test definition. Then having a common understanding of how layer height, width, speed and other variables can affect the results obtained when the standard. A Thus would at least get us going. Then we can complete by filling the blanks with real data when available.

Thank you!

Thanks man! still a lot to be done ahead, but I am quite thrilled with where we are right now.

Thank you! 🙂

From my experience semi-transparent and natural go faster than colored. I run up to 23mm3\s@0.6 nozzle with mil camo but black only 20 until skips occur. on 0.4 nozzle I had 14mm3\s on gray and black while natural and semi-transparent goes well at 15-18

It really annoys me they don’t publish which pigments/plasticizers etc are added. I wish there was a list like the one on food labels by the nutrition chart.

@@ericlotze7724 I guess this changes a little. base material of different manufacturers is different, dyes are different, colors are mixed from multiple dyes so even you know all the chemicals inside. I googled one common dye name please enjoy:D disodium;2-[[4-[ethyl-[(3-sulfonatophenyl)methyl]amino]phenyl]-[4-[ethyl-[(3-sulfonatophenyl)methyl]azaniumylidene]cyclohexa-2,5-dien-1-ylidene]methyl]benzenesulfonate Can you guess what is it? Can you guess how harmful is it? Can you guess how it affects plastics viscosity or temperature of PLA? Neither do I. That's why your best bet is to find quality material, do many tests if you make something on a scale, and stick with it :DDD That's why I use more or less average settings for different PLA colors so they a bit overheated so tougher ones get enough to be fast printing while it doesn't really harm those that are faster because of less dyes. Also I heard that some kinds of matte\pastel etc colors can even be more brittle but never checked myself

@@ricokaboom_ I get it may not mean much to the average person, but i think the data should still be there, same reason the stuff is put on the food labels even though people will often get scared by basic ingredients with big names, rather than look them up! Also Safety Data Sheets even for things like Cleaning Solutions may contain more information than most need, but are useful for research/planning. I’m rambling on a bit, but i feel like it would require minimal effort on their part, would aid in further refinement of Filament science (what specific additives make “good filament” etc), and FDM printing in general, as well as make planning for research (such as this) or health/safety easier.

@@ricokaboom_ but for all practical purposes, you are right!

Do they make sensors that thin? That would be really neat though, like a “downhole sensor” lol. Perhaps use a larger nozzle like 1mm?

A flexible surface mount thermocouple glued around the tip of the nozzle maybe a good compromise.

There's a paper (In-situ monitoring of polymer flow temperature and pressure in extrusion based additive manufacturing, by Anderegg et al) that did just this. They also introduced a direct pressure transducer into the nozzle as well and were able to get some really interesting results. Worth a look.

Thanks man!

Yeah... I felt we needed a more true life representation. Sorry for the delay.

Guess its never coming now eh @@MirageC

Thanks for the tips.

Will look into it! Thank you!

Thank you!

Glad you enjoyed it

Thanks man!

Merci! Oui moi aussi j'ai hâte d'enfin pourvoir "décoller" avec ce projet!

@@MirageC Salut l'ami, des nouvelles du test de la hotend Dyze ?

Just some ideas i had throughout the video, what do you all think of them?

At this point the level if effort to create one test set is still huge. Perhaps once I have improved the computing process it will be possible. But one area I feel should be improved before doing that would be to have a better control of the environmental conditions of the test room.

I just received 20kg of the same batch directly from Polymaker's factory. I also have the datasheet with flow index. I will use this for all olympics. Now I need to set room control and thermistor calibration.

Look up the quantum delta. It's perfect for this.

@sprkng had a comment along these lines. They mentioned using a rotating disk (akin to a “Polar Printer”) and just the Z axis to produce vasemode prints with minimal movement/vibration.

@@ericlotze7724 Yes, I see. That would work as well, but it would reduce the type of test prints you could do to different diameter cylinders, which perhaps would be good enough. If mounted on a simple linear actuator, this would improve - off course. You would also need a high VA slip ring coupling, to transfer power to the bed heater and to read thermistor values, which could also be done off course.

@@daliasprints9798 Had not seen that before, but yes, that would be excellent as well.

Thank you Ivan for your support 😀

You are welcome!

Awesome! Thank you to the info! Will ensure they are higher, and perhaps bigger. Note that I made a mistake in the last part. I have translated the pressure reading on the right axis directly. I should have taken the corresponding flow reading from that timestamp. In other words, we have now proof that pressure creeping point is pretty much where we start having bad quality print.

I dont think the minimal difference in measuring the extrusion deviation on the input side vs output side is significant enough at this point. Perhaps in the future when we understand all other parameters and diel them to the perfection, this could be looked at. But with the very constant flow request, the fact we have no stop and go and that this test has a very smooth flow change acceleration, the delta between IN and OUT is very limited if not negligeable. Everything coming IN will come OUT.

@@MirageC Sorry for the late reply due to my own tasks. My assumption was when the speed is high enough over a certain point, the the cold core effect and the higher and higher stress in the melted plastic leaving the nozzle start to lower the print quality until the result is eye noticeable. In a macroscope view the delta of mass between in and out can be ignored, but maybe the dimensions are different?

Thanks!

Both are part of the same equation. Nozzle pressure + system drag = motor pushing force.

Yeah, Hence why I stopped during the winter. I now have more computing power thanks to a partner firm who chipped in.

Thank you for the support! it is really appreciated! I might invest it into a good microbrewry beer though ;)

Yeah.... I need to learn on of these better tool 😉

Just a normal guy... very suborn though! lol

Although this would be super useful, I am not planning to do this as part of this series due to time.

I thought of something similar but the level of effort would be quite high. I wanted to test bowden first to see if it was a viable solution. Given the similarity with the first rig, i think bowden is just fine.

​@@MirageC Wow thanks for replying. I have been wondering if the limiting factor to extrusion speeds is how well the filament gets heated (if you go fast, the head might not have enough contact time to melt it even though the heater is really hot) or is the molten filament just limited by the diameter of the nozzle and physically will not extrude at higher rates. I have been wanting to have a really fast printer for years now, but all sources say it's relatively easy to make it move fast, but hard to get good extrusion.

I have one in the line up. :)

@@MirageC oh fantastic. I've just purchased the hemera heat break with V6 and the chc standard and the volcano. Yay I'm excited.

No I don't have one yet, but yes it would be super interesting.
