I am happy to see that you get good sponsors and totally understand that. The hard and amazing work that you are doing for free to the community is outstanding. And these sponsors make it possible for all of us that you can continue building crazy fast printers!

Great video! I learnt a lot, thank you. Btw, if you really want want kids, don’t leave it too long, I was in my late 30’s when we had our 2 and I’m 49 now. The kids are 12 and 10 - if we left it any later I don’t know how we would have both coped. You need a lot of energy to raise kids and I can say from experience that you really notice the deficit when you approach 50.

[@olafmarzocchi6194]

A similar video focused on faster but useful parts (technical parts) would be useful. For example, some of the settings which don't affect quality should be mentioned first (and kept to values which are still reasonable for quality parts), and so on

[@MandicReally]

My secret, I prefer "Aligned Rectilinear" infill oriented at 0 degrees (so the lines run the length of the boat), for higher speed. It shaves a fair bit of time as the lines are straighter & longer. I learned this trick by analyzing the Bambu Benchy sliced files. And my video production is closer to 2 hours per minute of video time, and my videos are getting longer... 😅 Always excellent videos Albert!

[@247printing]

Thanks a lot Alan - I’ll check this out for sure - never heard of that infill style!

[@MandicReally]

@@247printing It is an infill pattern in OrcaSlicer & PrusaSlicer, no idea about IdeaMaker. It is the same as Rectilinear except instead of alternating infill direction perpendicular to each other on each layer the lines all travel the same way every time.

[@802Garage]

@@MandicReally I was thinking exactly this while watching. Use the longest straightest lines possible. So Aligned Rectilinear also just called Lines in Cura makes sense.

[@Splarkszter]

Ha. Bambu are Cheaters! 🙃

[@AndrewBoraas]

about the slow retracts, if you're printing slower they help not separate the solid filament from the molten filament in the hot end. like since the filament is more molten a fast retract just pulls the filament off of the molten blob and you basically don't get a retract. This can show as popping bubble that follow retracts from trapping air between the more solid filament that was pulled away from the molten plastic. If I have a really oozey maybe wet filament a slower retract can help but I dont go below 30-40 mm/s. Or at least that what my experience seems to say

[@davidconner-shover51]

Yeah, I've run into that with one of my printers, had a nasty habit of clogging up the PTFE tube within the hot end. Running speed on PLA, I hadn't even bothered with retractions or z hop for BLO

[@ModBotArmy]

[@davidconner-shover51]

I used straight infill oriented to hold up the box in the back, I did manage sub 7:00 on my nearly stock Sovol sv07, but it wasn't pretty, still reasonably recognizable also threw the numbers with a .75mm layer height and 1.4mm line width on a .8mm nozzle. I ran that sucker at max feed 90% of the time. the thing wanted to collapse if you touched it before it cooled down post print Thank you for the benchmark numbers. I am considering a calculated under extrusion to deal with the The weird thing was that I could achieve nearly the same time out of my also nearly stock SV04, the flow rate was actually higher than my SV07 if pushed a bit, higher temps, diamondback nozzle... though limited by the 120mm/sec max travel, Orientation got me to 160mm/sec. that was also with a fat nozzle

After a year and a half on a close to stock ender 3 (minus a dual z upgrade and metal extruder parts) I went upgrade crazy this year, more or less doing every upgrade I would ever want. Spider hotend, sprite SE extruder, even small stuff like an LED light bar and bed insulation, but the biggest upgrade was prolly the Nebula pad and camera combo that gave me Klipper. After some tweaks I am printing at close to double the speed with nice quality.

Hey there, loved the video. I would recommend a few things: (personal note, think about kids, if it's too late you will never see your grand children, and that's one of the most important things in any mans life) 3d printing recommendations, mechanical stuff: Replace all of the 3d printed plastic parts, with 3d printed titanium parts from PCB way, you could save a few grams (the parts holding the linear rails) Next try to remove the part cooling fan on the hotend, do you really need that?, you have huge fans cooling it off already, maybe improve the side ducts to be closer and thinner (more accurate). Do you need the thick high flow hotend?, doesn't a normal one work with a CHT nozzle? Have you ever tried printing with a 0.6mm nozzle? Have you done k-value calibration, that can improve corners (speed up prints) a lot. I was able to speed my ender 3 up by 50%. These are all recommendations made with common sense, maybe one of them is good. Thank you for the content. Have a nice easter, take a break with your loved one, best regards from Switzerland.

[@knucklehead83]

I was 43 when I had my youngest child. I was 23 when I had my first. It's rewarding, yet frustrating. Another secret: I bought my first 3D printer 3 years ago. But sold it before using it because of a battle with cancer. I bought my second 3D printer last year, and printed a pokemon when I first got it. I packed it up and didn't touch it again because I was intimidated by the idea of slicers and g-code and all that. Until a week and a half ago. I pulled out my Fokoos Odin 5, set it up, and printed a Benchy. Ten days later and I've got the basics down in FreeCad, I've designed and printed a ton of store shelves for my wife and daughters Mini Brands addiction, printed out some Thug Life glasses, and have become quite familiar with the simplicity of the hobby. It's intimidating, even for a guy that can do anything. Breaking that bubble is the hardest part.

[@247printing]

Thanks a lot for these insights into various aspects. All fingers crossed that you won the fight against cancer for good! Learning new stuff can come along with anxieties (and therefore procrastination) for sure. But mostly, when mastering a topic, the feeling coming along is priceless - you physically printed your own functional designs - how cool is that!. Lately I described the same for learning CAM on the Carvera video lately. Breaking that bubble is absolute key!

[@nunovicente34]

Awesome video as always man! Id definitely like to watch some livestreams! Like doing a walk trough of your 247 V0 build and other printers. But first please release the B0 files I really want those widened feet! 😂

[@Duckferd]

What do you think about the recent Speedbenchy records being set by extremely modified Ender 3s? Do you think you that the Voron 0 can reach those speeds if you went all in with crazy motor setups and gantries that don't even look like beams anymore? As far as a livestream goes, I'd love to see you push things until they break XD It's one of the things I've enjoyed watching on your channel, like on your A1 mini review the fact that you pushed it far enough that you got strange cooling artifacts and we got to see the bed move up and down to compensate for warping.

[@ashers_workshop]

Maybe he should put 4 motors for the XY Gantry like I saw someone do on a 2.4 ab motors in the back and another 2 motors in the front

[@henninghoefer]

OK, answering your questions: * 15:26 What do you want to see on a 247printing livestream? I would like to see how you start and plan a project (like your Voron 0.1). Do you start from parts? Or in CAD? How does a new project come about? What do you do before the actual build? * 16:30 Why do default profiles have so slow retracts (30mm/s)? Even my first 3D printer (a cheap Ender 3 clone) came with a 70mm/s retraction profile… If I had to guess I'd say, they try to reduce stringing by retracting slow and wiping/z-hop at the same time?

[@dylanlasky2389]

I just got a v0.2 kit today this video is just in time

[@ushiocheng]

Not really doing speed boat myself since high VFR hotend loves to string which is an issue for functional parts. I managed 800+ mm/s at 19k acc with just 0.7A 24V on LDO motors which translates to 64mm3/s (at 0.2 layer, 0.4 line) which is not really possible on a V6 style hotend without melt zone extension that impact stringing. currently pushing 30mm3/s ABS on rapido which hard capped my benchy at >10m another annoying thing I found is non-external perimeters also impact the tolerance so all my perimeters are pretty much limited to 200mm/s for quality parts. also PA is slightly dependent on speed so if you more than doubled your print speed you need to re-tune PA+EM.

[@VascoRocha]

I think that usually people don't want to touch and broke when things are going on... So the retract speed instead of 120mm/s is commonly 25/30/40/50 because of upgrading small steps so you don't broke your things... Is there a retractable speed test so anyone can measure their extruder capabilities? Would be glad to do some like that... Even though having a direct drive extruder... Thanks for all your sharing and thoughts! 🙏

I can't reproduce it during any print and every other possible angle is silent, but the macro gets it every time. wondering if it's just a coincidental resonance frequency.

i feel like your livestreams could go a couple of ways. Either it would be just you working on the printer and meanwhile talking with the community ( kinda like nero3d) , there is really not a lot of ways where a 3d printing livestream can go, while being entertaining. I guess you could design a from-scratch printer with chat on livestream where you discuss the disadvantages and advantages of your design choices to chat and answer questions (you could put VOD's of that on your channel) It would be very valuable to people who want to learn about designing 3d printers and propably CAD design in general. Like a made from scratch printer that you design ENTIRELY on stream and then you release the files to, while being able to help and teach other people along the way.

[@247printing]

Thx! I could watch and comment speedboat videos for example - what do you think?

[@SirLANsalot]

The reason the settings are very conservative is, not all printers are made equal. So you aim for settings that "should work" on all printers. That is why the speeds and retractions are set so low, as I have started to tweak and push the numbers higher on my Voron 2.4 350. Printer config max speed is 300, but I can't get much better then 200 because of standard PLA even with a Revo High flow. High speed PLA I can get to the max 300 speed because of the Revo HF, its been a matter of tuning the Jerk speeds and accels and watching to make sure no belt skipping happens either. Oddly the new Neptune 4 Max I have is "supposed" to be faster but it hardly will ever reach 500mm print speeds because its a bed slinger. So the Jerk settings are going to be slow because of the bed and its massive size. Great to have a large form printer, as even the 2.4 350 I have is quite big too. Just funny they claim 500mm speed, but it really can't do it even using their Elegoo Cura profile. That is another part of the reason the settings are so low by default. Not all printers have high flow nozzles, and most people will be printing with Normal PLA which has a lower viscosity. High speed PLA melts better and flows better in how its formulated, that is why you can get such crazy flow rates with it. Granted using normal PLA with a HF nozzle WILL help get better speeds when using cheap PLA but to get speed boat level prints, high speed is required. Usually HSPLA is a few bucks more then the normal stuff so its not going to brake the bank if you buy just HSPLA.

[@nutzeeer]

[@jimbob1er]

With high extrusion speed the flow loose accuracy 5%, 10%, 15% and eventually too much. Is it possible to compensate for the loss and prevent under-extrusion. The speed of extrusion is known, the ratio of loss vs speed can be measured with tests, applying correction from a table should be possible? Gcode post-processing? Then the wall lines should create solid part.

[@skaltura]

oh my, and here i did 12:00 (including homing, preheated!) benchy on a mechanically stock SV07Plus and it looked like a benchy :O I probably need to make a #speedboatrace video then i guess

[@sabahoudini]

You can improve the center of balance of your moving mass. If you look at your printer the Y rails are positioned much lower than the moving mass. If you place everything on the same plane as the belts then every motion will be much more efficient. It's like throwing a spear. If the energy is going in the same direction as the spear and passing right through the center point of it you will have a very long throw. So my suggestion is to remake the printer so that all rails are on the same plane in Z and the x beam is on the same plane as the rails (no top mount) and also make sure the toolhead has it's center of mass on the same plane as the rails and the belts are also on the same plane in Z. This will also drop the requirement on evertyhing being super stiff as there will be less torsional effects so you can make things much lighter. I'm looking at your xy joints specifically, those can be aluminium probably and save 150g of weight. You can also go 4WD maybe, although it's a very small printer. Or maybe wider belts.

[@travistucker7317]

Voron zero barely has 150g of printed parts

[@sabahoudini]

@@travistucker7317 The XY joints alone weight 150 gram. Those can be reduced to 50 gram and made stiffer by using CNC aluminium and also titanium fasteners. Also the center of mass matters. If the moving mass weighs maybe 350 gram now then a reduction by only 100 gram will be a huge difference relatively. However the whole printer can be redesigned for better center of gravity, that will make a huge difference in reducing secondary vibrations and leave only the funamental resonance and produce a very clean spike on the resonance graphs.

[@travistucker7317]

@sabahoudini i think you are talking about the entire gantry with extrusion and bearings? Lighter gantries exist, of course. Xy joiners are like 15g per side already. The bearings probably weigh more. And you will save something, but not much with ti screws.

[@sabahoudini]

@@travistucker7317 Trust me dude, I've been chasing grams on my voron and everything adds up. I know this one is lighter than my 2.4 but if you take off the moving mass (everything that moves in Y) you will see it weighs more than you think. However the torsional rigidity and center of mass is more important for print quality. The way the linear rail is fastened to the CF beam is a weakness and the rail can wbble on the CF beam if done improperly. You need a printed insert and a screw that goes all the way through otherwise it will not be stiff. I see many things that could be improved.

[@travistucker7317]

@sabahoudini We started on xy joiners and are now on the entire moving mass. All 4 stock joiner printed parts are 30 grams. Other than bearings and screws, that's it. There's not much to shave there. Seems like you could do much better working on a lightweight tool head. I think using Albert's gantry setup should get you where you want to go unless you just want to build a printer. His entire gantry and toolhead is 175g. What have you done already?

[@Reds3DPrinting]

You might of wanted to put a warning of "dont try this at home" xD lol NGL im excited to see how many people destroy their printers trying to print worlds fastest

[@MrRocksalt]

I just want to stand up and introduce myself. I am a benchyholic. It's been about 4 day's since my last benchy. To me it's not important to make 7.5, but to make 7.5 with quality. I find that for fast speeds the flow seems to be lacking. I can see this in your prints also. What gives... Either the toolpath is not on point, or there is some reduction in flow?

[@333donutboy]

The quality of the benchy is really good considering that it printed in 7:30. Everyone needs to keep in mind that a stock Ender 3 can't do this. Voron's are beastly printers and can take this kind of punishment.

[@skaltura]

How about subambient cooling? ;)

[@arteuspw]

nice video!

[@247printing]

Thanks!

[@97hondacivic]

5:17 that would be true for Cura, Slic3r and its forks use a different model for calculations

[@247printing]

How do they calculate flow rate? Can't imagine another way. Cura has a flow cap value? That's new to me!

[@97hondacivic]

@@247printing cura assumes that the extrusions are rectangle-shaped, but slic3r and its forks assume a pill-shape - a rectangle with semicirles at its ends. so orcaslicer printing at .25 tall and .45 wide with 106mm/s would only be 10.5mm3/s. to get 12mm3/s you'd need to go at 121mm/2 (because the pill shape has a smaller area than a rectangle)

Can you print nylon or pc that fast ?

[@tonytillman3953]

Why didn't you turn the benchy 45 degrees?

[@247printing]

Doesn't help here

[@MarinusMakesStuff]

Future civilizations will make such fun of us. In the ruins of ancient London: "Sadly, they didn't achieve world piece and destroyed the ecosystem so they disappeared shortly after the fourth industrial revolution" - "But it looks like they did achieve a 3-minute benchy!"

[@SebasTian-od7oz]

@247printing I found somebody currently realizing an even faster concept for core XY (due to less gantry mass). Curious if he'll succeed with just 2 carbon rods as basis? Video title: "Celeritas World's Fastest 3D Printer Concept, Introduction, CroXY with Carbon Fiber Tubes." kzbin.info/www/bejne/jYm4eIaLn5ulgNE&lc=UgxrVja4UMZj3UaXs2B4AaABAg.A2hV4gDI9A8A2iInIk648K I'm sorry that this comment is slightly out of context for this video.

[@247printing]

Thx for sharing, I was wondering when someone finally does exactly that - needs to be extremely fast!

[@TheZeemyself]

what about infill combination

[@247printing]

Zero difference. Capped by flowrate as you just double layer height of the infill. I should have mentioned this, thx!

[@802Garage]

@@247printing Sounds like you might be able to extract more speed by uncapping the flow rate only for infill if possible or by uncapping flow rate and actually restricting just outer wall and top layer speeds, allowing some under extrusion.

You mean without the dry run it would sound like onlyfans?

[@247printing]

There is no impact on the content or on 247printing per se and you can just easily skip the ad (see time stamps) as well as not play the game. There is no need for complaining. Thank you for watching - btw.: Crysis 2007 is one of my all-time favorites - kids like that game as well ;-)

@@247printing common, your content is excellent, and your audience has technical mindsets. Proposing a mobile game that aims to suck money by abusing cognitive bias, targeting vulnerable people, seems a poor choice. I'm sure you may contact technical firms as sponsors (related to technical fields: like 3d printing, technology, electronic, etc.), more in adequation with your content and audience.
