- POP QUIZ: How long did it take to print each nozzle? Stacking parts reduces downtime and increases throughput 💪🏼 #nexa3d #xip #mSLA #printstacking
approximately 1hr:14min per level,
16 nozzles at each level will be completed simultaneously.
That's what I wanted to say...
Exactly!
The math in the video only applies to fdm... And even for an fdm it'll incorrect
Me too
Same
Yes .
Since it prints all of the pieces in a layer at the same time, wouldn’t it be the same time for one as it is for the whole layer?
Exactly that. That’s why filling up the build plate and cramming as many parts into a layer improves throughput!
@@Nexa3D yep but the question literally translates more to delay than througput. You wait an hour and 14 minutes to get the one nozzle (and 15 more). You need that, even if you get 16 at once. Delay vs throughput...
yeah it would be divided by 4 not 64
@@TheRealDarklight valid point for just in time delivery or a single piece flow situation, but then you add on delay for setup/startup time which for that many pieces would be insane. Batching is different. If the target is to complete X # of nozzles in a day then this method actually has less of a delay overall.
Well in terms of business time I would divide by 64 or 16 because I would make them in that quantity to keep my effective time per item down. But function how long for one is a dif question. What if I wanted one custom. Would you still say a 4 min print?
This is how you drive engagement. Say something obviously erroneous and let the engagement roll in. Well played.
Yep Murphy's law
Yes, you do certainly seem to be doing that pretty well.
@@zyeborm I do my best.
@@masontowey how does this relate to that law?
@@masontowey nice try.
It’s a resin printer, only the height matters because it does the whole layer simultaneously.
Yes , and exposure time too , monocrome printer are much faster
They make galvo-based resin printers that print layers like an fdm
@@afurryferret yeah but they cost lots, the resin costs lots and they are slow and crap. I've used both side by side and I'll take a Saturn over a form labs in a heartbeat
You are printing 64 parts stacked at once while I’m here trying to level my PLA printer for three days to get one decent part 💀
ABL is a life saver haha
Highly recommend an auto bed leveling upgrade if possible!
RIGHT meanwhile he is getting a cube of perfect parts
I'm getting rid of my ender 3 because it's been nothing but trouble lol.
Bro that is so true
I even have an auto level and it’s still not level
SMH :/
If you printed a nozzle alone it would take about 1 hr. I thought this would be about print optimizations
If you print 64 at once, you have enough time to go out to eat, take in a movie, walk along the riverfront. If you do only sixteen at once, you have to babysit the machine by being there every hour to remove the parts from the bed. What's optimization when considered from the point of view of your time?
Does one nozzle not take printtime divided by 4 because of the stack of 4?
Indeed
Well it depends, if it’s only 1 stack of nozzles(all same height) it would take the same time to print 1 or a full build plate
yes, but if you factor in setup time, it's more efficient this way, because in that time it's making 16 times as many parts with the same amount of setup and cleanup time
Fundamental misunderstanding of how a resin printer works, but sure, why not, it will take you 4 minutes to print 1 nozzle. Z axis, what Z axis!?
he's right though, if you're trying to make them as time-efficiently as possible, total time divided by number of parts is the right measure to use. if you printed only one Z group (16 total) you would have 4x the setup and cleanup time for the same number of finished parts
Thats insane😮
Each would take something like 1hr 13 mins.
Youre only increasing your output by printing more, not altering print time. You could argue the average time per part is lower but in reality its not because youre using SLA. You could cram 60 parts on a layer and the time for each would be the same, youre just investing that time simultaneously opposed to sequentially.
Flawless logics
I believe that with more tight configuration you can double the production of the existing production
I got a 24-hour job with 384 identical pieces on it. Even though it took a day to print, each piece still took less than 4 minutes. Stacking Prince is awesome!
Yeah, that wrecked my brain. Cause I was thinking in layers.
Great work this episode! No math/material related comments for today, now just waiting for some supercoolant
What are the nozzles for?
This is the best math problem I have ever seen
Interesting rationale
The math might be wrong but the idea was there ❤
@Reulorics cus it's layer printing, not nozzle printing, meaning that each layer is done across the whole plate, meaning there is 16 on each layer, so it basically prints 16 at the same time
if it's the amount of time the nozzle spent hovering over and extruding That Specific Nozzle though, id imagine it still comes out to about 4 minutes
Technically it is more because you are using an resin printer which means that each vertical group would be considered as one singular block that weather you are printing 1 or 20 they would take the same amount of time since the printer exposes the entire bed at once. So if the total amount of time for a stack that is 4x4 by 1 tall takes 1 hour, then a single nozzel will also take 1 hour.
but with resin your printing one whole layer of nozzles it doesn't matter if it's one or 20 its the same speed
Love that my resin printer can print threads!
it would still take about 1/4 the time, because each layer as a whole prints near instantaneously, so the only dimension that adds any noticeable time to the print is the height, it would take nearly the same amount of time to print 1 as it would to print 16
are you messing with me? he asks at the start of the video how long it would take to print just one, that’s why i’m talking about how long it would take to print one, never would have imagined that to be a difficult concept to grasp
My brain at math exam :
I guessed 4.5 minutes doing math in my head so I’m not too upset
Depends if you're printing separately or not but since you're using a resin printer most likely depend on how much you're printing thing and won't affect the time that badly
Do those nozzles actually handle real world stress without shattering?
Nope
Can you make a video showing tips for stacking prints ? Pleeeeeeeease 🙏🙏
There is also an argument to be made that it takes just about an hour
@Reulorics if they were being made at a rate of 4.5 minutes, you could wait 4.5 minutes for one to be completed. They are completed in about an hour, but they are completed 16 at a time :D so to complete even one would take an hour
Lol I took way to long to figure that out 🤣
Doing this in my head, about 4 minutes
What is the nozzle use for is it water or air
The question now is how long does it take to separate and cleanup each part
I’ve personally found that putting too much in one print is risky and will potentially cause delays longer than just printing in smaller batches
"Machines making machines making machines..."
What about cleaning, curating and support removal?
If anyone sees this and can answer it would help a lot. I'm going to buy a resin printer soon and am curious about something. If I print one cube that took hypothetically 1 hour to print on my resin printer then went to print it again but this time with a second cube of the same size near by it would still only take 1 hr right? I don't know much about 3d printing so if someone could answer that would hep! Thanks!
You are correct
@@grimxenxd1590 not completely.
If printer is display based then yes, entire table is expossed in parallel.
Also on the market available laser scanning printer, as result the more you put on the table, the longer it takes to expose. But it allows to print with more pigment loaded inks.
"4 nozzles deep" ☠️
Roughly 1 hour and 15ish minutes per layer
That's what I got
Unless it is a laser resin printer which prints like an fdm with a laser tracing the layer then it would be slower for the whole layer with more nozzles
Since this is a resin 3d printer, it takes same amount of time to print every layer so it would actually tale 1 hour and 14 minutes to print one nozzle
Bro that printer is like 10.000 dollars 🤑
Roughly around 4.5 minutes EACH nozzle. You can reduce the number the more nozzles you put on the bottom layer. If you did only 1 then to print that one would take 74 minutes... If you did 75 on one level then you can reduce the time to about a minute per thing
We know from the type of printer bieng used each nozzle in one layer takes the same time.
So if we have 4+(56/60) hours divide that by 4 ( because 4 layers ) and you get 1.23 hours which is roughly 1 hour 14 min
Since he's printing in stacks you can't define how long per nozzle but for simplicity sure, 74 min / 16 ( because 16 nozzles per layer ) is exactly 4.625 min ✅
Never thought I'd say this to a dude but, nice stack.
But it’s a resin printer so the amount of nozzles per layer doesn’t matter?
I have an ender 3 v2 and for good prints and for it to stick i put it at most half speed maybe 25%
I mean about 1:14 per level, and 16 on each level, but since it’s resin and the layers are all made at the same time, it technically takes 1:14 to make one, but it takes the same time to make 16
@Reulorics it’s not 4:38 per nozzle because if you printed one, it would take is one hour and fourteen minutes
It would really be the total time divided by 4 since a resin printer prints the entire layer at once now these calculations would be correct if it were a Traditional 3d printer so really it would take a little over an hour just to print a single nozzle
Just divide it by 4. 1 will take as many as 16 in one layer.
And here I was calculating how much it would be if it's single vs batch
Sweet mustache, bro
That's quite fast for a resin printer, mine (monochrome LCD) would probably take 10-12 hours for that print with my current settings. Any tricks I should be aware of?
Not really possible to achieve the same speed on a consumer level printer. Nexa3D has a proprietary membrane tech that allows faster speeds. The cost of the printers are much higher than consumer level printers though. It would be much better to get multiple printers if you want the same level of output.
What about the heating a cooling times once the print is done. Most printers have a cool down period before you can pull them off so they don’t stick to the build plate
Well one nozzle layer takes 1h 14min ish, it's just a matter of how many nozzles you fit per layer, one layer takes same amount of time no matter how many you have next to each other, it's really just downwards that takes longer
It'd actually take roughly an hour and a quarter. Its a resin printer, so how much per layer doesnt matter. It'd take just as long to print one nozzle as it would 16.
Wow I thought it took longer. Like hours. But I'm guessing that depends on the size of what's being printed plus details.
It depends on the vertical height of the print, so it'd take as long as one layer.
Put in other words: If it takes an hour for a factory line to produce 1 car, how long does it take for 4 factory lines to produce at least 1 car?
What do u use these Nozzles for? Looks realy good, only got a FDM Printer...
I did that in my head and got 5 mins 🤣🤣🤣 didn’t even use a piece of paper and pen either I was close since it was all guess work
I'm doing research now. Do 3D printers have proprietary software in which you determine the stack, or do you do this separately in other visualization software like Rhino, Maya, CAD, etc?
You would do this in the slicer for your printer and align them as needed iirc. At least that's how it would be for an FDM printer. Not 100% sure about an SLA printer.
@@thecodeking91 sure. That wasn't really as I was saying though. Prusa Slicer, Cura, and others are out there for whatever slicing is needed. When I said "for your printer" I more meant that because some are locked in (looking at you Bambu)
What printer are you using and how do you get good ventilation?
Brother can it print action figures/venom spiderman if it can love to see one video on it
Yeesss 😂🎉
If only we could print in 3 dimensions simultaneously
Not true, it prints per layer right?
x and y does not matter with sla what determents the print speed is purely depended on on the z axis and how high you are printing if you layed them out better like 6x4x4 you would have 96 instead of 64 in the same amount of time but you would probably have to top up the resign halfway trough the print
More money than sense. Can't even get his own question right😂
They all do mental gymnastics to justify buying one of those
Technically you should consider it by layer, this division is just an overall view
More like divide by 4, because depth/height is actually your greatest variable
Printing 1 nozzle would take just over an hour tho because you are using sla this makes sense if you are on an extruding machine but resin printers work a whole layer all at the same time
I wish I could have a 3d printer
I GOOGLED IT ITS 278 SECONDS AND THATS CLOSE ENOUGH FOR MEEEEEEE!
One nozzle would take 1 hour and 14 minutes to print. 16 would also take 1 hour and 14 minutes to print. And each nozzle will take 4m38s to print so long as you print a multiple of 16.
Were these printed with regular resin? I recently heard about a high speed resin that allows you to print super fast.
But with 16 being on a single layer, wouldn’t that mean the 16 units roughly finished at the same time? Meaning each nozzle takes the amount of time as a whole layer of them at 74 minutes.
it technically prints in the same time of all of them combined ;p
This is the correct answer. Approximately 1hr 14min per single nozzle print. compared to 4x nozzle print
2 minutes 14 seconds for a single full speed nozzle
dude, it is 1:30am. Math is not mathing for me right now. but cool
what are those for?
What are your exposure/LOD, Retraction settings? I still get like 18hrs on a Mono for something 20cm tall.
How do you stack the parts in the slicer?
What do you use the nozzles for
What printer is this? I’m interested in starting to do some resin printing to complement my fdm printing
I think the bigger question is, why do you have four nozzles cubes, and what are they for?
Ah! The infamous 9 women had 9 babies in 9 months version of math. I get your point though.
what kinda printer do you use because my friend has a resin printer and says one of those nozzles would take 4 hours alone
You were using a reason, 3-D printer, which means you can buy layer not by paste
I guess what u mean is since you cramped 64 nozzles on this print, how much time does it take for each nozzle on this print. That way your calculations is correct.
That's just wrong, a resin printer don't print a nozzle at a time, it goes in layers! Please think before posting a video
Each level takes 74min to print, and each nozzle on a layer will take 5 min to print, but if there is a single nozzle printing it probably takes ~20min
Just guessing, hard to know how long a single one would take considering it’s based on layers more so than width and length.
Same time as the total of one layer took
WHAT ABOUT SEPERATION/CLEANING TIME
So this is the mean average time per printed unit if printed completely right?
Because if 296 is the time to print all of it then one layer should be 1/4 the time.
That's 74 minutes. And if you divide by 12 pieces it's about 6 minutes each mean average.
So the lower print time is only a function of averaging a higher sample.
@@thecodeking91 I stand corrected. Was heavily under the influence of post surgery high power drugs when I did that math
Compared to traditional manufacturing that's still incredibly slow. Additive manufacturing is great for prototypes and one offs but it's a long ways from being used for mass production
Okay but what resin printer is printing that height in 4 hours 👀 mine take about 40 hours to do a 1ft tall print
296/4 = 74. It takes 74 minutes to print 1, or at least 1. This is a simplified form and doesn’t account for base layers and any supports between the base and first pieces.
but for resing you must include the necesarry post processing
Unless im mistaken. Due to this being a resin printer, won't it print each layer of the stack in the same amount of time regardless of if it's 1 nozzle or a say a 3x3.
Saw a video one time explaining why resin printers are good for nesting prints because where the normal filament printer has to do each print individually but the resin does it as a layer so everything prints at once. Is that right? Or better yet did that make any sense? 😂
1h 14min per 1stack - 1 nozzle + any more you want on the print bed to print in the same time
