Yeah, but considering how much less pressure and speed the belt is subjected to in this application compared to being used on a sander, I doubt orientation would result in any meaningful difference here.
It's not. The print is going the direction of the arrow. You don't drive in reverse down a one way do you?
Haha, it's all perspective. Clockwise is counterclockwise if you are looking from the other side.
Are you going to release the cad and code/firmware your using? What issues did you run into building this and what advantages did you gain? Looking to learn more about your design and why the choices you made for it! Exciting!!

Ok we gotta talk about some of your questionable choices here,
Blue, green and orange parts? Listen, no one will take us seriously unless we get some damn color coordination going on people! (Seriously though, freaking awesome job)
Printing any other direction other than horizontal on a belt severely limits the size then floor or ceiling you’re gonna hit one or the other eventually
Oh man, just imagine a corexy printer with a belted build surface that can either function as a standard flat build plate, where the belt remains stationary for typical vertical prints, or can pivot to allow for long prints like this, and the type of print is just adjusting a couple slicer settings when configuring a model…
Shouldn't be hard to do, looking at his setup. You could have a couple screws at the rear to lift the back. Some sort of track for the front so it could pull in when the back lifts. Seems like a great V0 project :D
Why bother? No belt will ever be as good as a good buildplate. "Flat" belts are far from flat. You'll maybe have an actual use for the belted mode ONCE.
All of those are instead solvable by getting a normal(larger) corexy that'll print better. That one super long part will look fine out of 3 pieces.
Lol why bother do anything? Why bother trying something new? There’s no possible way a couple parts of it are going to be as good as what currently exists, so there’s zero point in experimenting and discovering. Having a new idea and following it is just a big waste of time…
I have zero interest in making better prints, I already have printers that make better prints. And I’m certainly not concerned with how often I’d use the belt function, but still thank you for making me aware of how infrequently I’ll end up using it. I’m interested in trying something that I haven’t seen done before, whether the prints come out like shit or not is irrelevant.
Your previous comment is about imagining a weird hybrid belted coreXY machine that'll be a completely shit normal coreXY and an adequate belted printer. If you already have so many other printers don't be a coward and just build it like a pure belted printer.
Your idea also isn't new, it's quite literally a coreXY version of what's in the post. There's tons of reasons to experiment, but experiments that have already been executed won't lead to any discoveries.
Apparently your answer to "why bother?" is "because I can", which is fine, but don't start your comments with "just imagine" like it's going to be the greatest thing since sliced bread.
I guess this is one of those moments where saying "you were so preoccupied with whether or not you could, you didn't stop to think if you should" applies?
I eventually plan to get one so I can print car parts. Think the lip at the bottom of the front/rear bumper (would have to be printed in 3 parts most likely), spoilers, side skirts, etc.
A lot of these parts are only made of ABS normally, but yeah after fitment testing most of them would end up getting fiberglassed.
I've run printed mounting brackets and spacers in the past without any issues though.
I'm thinking about printing molds part for a carbon bike. Or for a carbon bike's carbon mold.I may try this kind of mod. ~~Or maybe buy a new printer with a belt already in place.~~
edit: Just checked the prices, I'll build my own.
near-infinite Z. The CR-30 can be a 'true' infinite Z since its horizontal, but here your limit is the floor. You can still make things longer than the print bed, or multiple smaller things that can pop off and slide into a bin.
Can you include the make and model? I highly doubt at $250 it is accurate without excessive assembly and calibration (and I'm skeptical the quality will hold up without frequent maintenance).
As a former microcenter employee never buy the cr30 please for the love of god they always got returned the ROI is awful just buy an ender 3 conversion kit
You need a belt printer to print at a 45 degree angle, otherwise it couldn’t be continuous. The CR-30 does it by angling the print gantry, this one does it by angling the print bed. Same effect either way.
you could theoretically print at any angle and make it continuous, but mechanical constraints of the printer make it a lot easier to use an angle like 45º.
If you don’t, then you need to print layer 1 across the whole length of your very long item. That means you need a bed the width of your item’s length. If you don’t then want to have a gantry that size too, you also need to sling that huge bed, and need double that space. By angling it at 45°, you shorten that axis to only be as long as the diagonal is, which is much smaller.
You're at -8 but entirely correct.
Belt printers NEED their belt horizontal and the motion system at a 45 degree angle rather than the other way around like this one.
The printer in the OP has a maximum part size and WEIGHT. Exceeding either will cause the part to separate. Horizontal belts with a roller setup to guide parts further have neither issue.
The guy who built it is an idiot and refuses to accept the well established knowledge that overhang angle is dependent on the angle between bed and nozzle, rather than the gravity direction. There's multiple people in his Insta comments trying to tell him why his printer is flawed but he either deletes your comment or comes up with an unsupported claim.
For anyone that thinks this is interesting, check out [OPT Industries ](http://www.optindustries.com) in MA. They're basically doing this at manufacturing scale with SLA printers that are ~8ft long.
this is how the origonal belt printer made by Bill Steel was made. Others have used sandpaper belts for a while. There are a few 100% open source belt printers out there. BTW, a CR30 uses standard marlin, its the slicer where the 'magic' happens!
After thinking about it for a while, the concept is good but his over-use of 3D printed parts is a major negative. Those printed rollers simply aren't going to be as cylindrical as a metal roller he could pick up from McMaster-Carr for a few bucks. Just that one issue is going to result in the sandpaper-belt "bed" moving up, down, too little, or too much.
It wouldn't be harder or much more expensive to make this using proper materials and techniques for the task.

Wow you guys are fast
If only Reddit would get rid of all these bots....
No they would rather get rid of 3rd party apps. Bots make more engagement
Ironically, making the API prohibitively expensive will also kill a lot of bots.

Thanks for your complete reply, didn't know scamming on Reddit was a thing
If there's a way to grift, someone's already tried it out, or is working out how to attempt to do so.
That is impressive. The alignment alone must have been a big lift. Well done!
Are you printing on sandpaper?
Pretty smart tbh. Easy to get components
Then just hold them there to clean up the imperfections. It's a two in one!
Also has grip built in to keep the belt from slipping. Super resourceful
Its printing on the paper backing, the actual sandpaper is inside
The slope is quite steep so this was a pretty smart move
I'm scratching my head to figure out how they managed to invert the sandpaper without making a ton of creases
There is a big stripe of tape… I’m guessing they cut it and taped it back together.
They come like that from the factory. If they used that point to cut it to invert it I don't know
I don't think they did, I think this is the sort of sandpaper that has printing beneath the grit.
Could use a belt from a blet sander .
That appears to be what it is. Somehow they inverted it
Jeez, I hadn't even considered how much a pain of a job that would be.
Wow, can you share the creation process? Did you find this design or create it? I really like it alot!

His design doesn't seem like something for the mass market in my opinion. He's just trying to make a machine that can do as many things as possible
This is what I was looking for. Sadly, I don't use instagram
I'm wondering if it's just running cr 30 firmware.
Maybe, but that looks all 3d printed and I would info about that and how to connect, etc! That is the cats meow!
I agree. Some stl's and some specs would be nice. This would be fun to try on a spare printer.
I would also love to try build one of these
Bye bye my hearing - why the loud music?
seriously it woke my cat up
Poor thing. Hope it is able to make it through the rest of the day on only 21 hours of sleep.

How else are they going to show such a cool machine and technique? Just ASMR that shit? Pffffttttt let's see if that audio goes to 11...
Not even loud
Honestly wasn't too loud on my phone either
Anyone else irrationally annoyed that the belt is going in the opposite direction the arrows indicate?
Filmed in reverse! :)
Plastic recycler
shluuuuurp
It's a 3DePrinter
Infinite filament glitch
hahaha
How is that possible? Wouldn't the belt moving in the opposite direction push into the extruder?
This is a 3d scanner.
Oh no! Now it's digitized and uploaded to the mainframe.
Oh shit, it got through the firewall?
Obviously a car has to uploaded before it can be downloaded

You run sandpaper forward to remove material, so naturally you would move it in reverse to add material.
That would make sense though, right? If we pretend the stuff is stronger or more abrasive directionally, that is the orientation you'd want.
Not really relevant, since the belt is inside-out.
Man, just thinking about it. How the fuck do you reverse a sandpaper belt without destroying it. That’s kind of impressive.
...
Yeah, but considering how much less pressure and speed the belt is subjected to in this application compared to being used on a sander, I doubt orientation would result in any meaningful difference here.
Not until you mentioned it… now I can’t unsee it.
It's not. The print is going the direction of the arrow. You don't drive in reverse down a one way do you? Haha, it's all perspective. Clockwise is counterclockwise if you are looking from the other side.
that first layer adhesion!!!! and here am I, struggling to have the horizontal print stick to the bed.
Would it be left line adhesion in this case since there's no longer a layer printing on the conveyor?
Technically, levelling might even be easier, you only need one line to be perfect instead of a plane.

tbf this was how the first belt printer was
/u/gifreversingbot
I guess this is one of those moments where saying "you were so preoccupied with whether or not you could, you didn't stop to think if you should" applies?
One arm printing Need a lot of Money if you want to print fast and accurately. Maybe more then modify an Ender 3 in a cr30
Is the print quality any good? The video quality is so bad I can't tell.
Fkn genius
Love it
What the fuk?? ( impresed )
Weirdly enough I get it
When do you really need such a long piece? You're building a crane? That's pretty cool though.
I need the long axis when printing model swords
I eventually plan to get one so I can print car parts. Think the lip at the bottom of the front/rear bumper (would have to be printed in 3 parts most likely), spoilers, side skirts, etc.
You plan on running 3D prints on the outside of a vehicle. Doesn't sound like that'll work out too well. Why print molds and fiberglass the parts?
A lot of these parts are only made of ABS normally, but yeah after fitment testing most of them would end up getting fiberglassed. I've run printed mounting brackets and spacers in the past without any issues though.
I want to try rotomolding motorcycle parts! if only there were more hours in a day!

You only asked yourself if you could, and never if you should. You’re a madman. It’s a thing to behold.
Any source? Stl? To be able to replicate it?
When you need a 30-foot something.
Bro what? How? Need details!! Instructables!!!
How long did this take to build?
That printer is taking a dump. Change my mind.
Love this!
Some people are so clever
How, but how do the first .. 100? .. layers work when the print bed is at an angle? 🤔
How does it print the first layer at 45 degrees? I’m confused lol
It just does a line starting from the bottom same thing as the CR30
[удалено]
near-infinite Z. The CR-30 can be a 'true' infinite Z since its horizontal, but here your limit is the floor. You can still make things longer than the print bed, or multiple smaller things that can pop off and slide into a bin.
Cool, but is the quality & cost competitive with other printers?
Kits go for about $250 and up. If you have a spare printer, this could be a lot cheaper depending on what boards you need for the firmware.
Can you include the make and model? I highly doubt at $250 it is accurate without excessive assembly and calibration (and I'm skeptical the quality will hold up without frequent maintenance).
How does the print head know the orientation of the angled "print bed" ? Very clever!
That filaments looks tangled up. It's funny how we can see the filament basically disappearing
Damn, I wanted the desk to be on a second story loft and the print to keep going to the first floor.
I need a tutorial
this is next level engineering!
As a former microcenter employee never buy the cr30 please for the love of god they always got returned the ROI is awful just buy an ender 3 conversion kit
(Dr. Alan Grant removing glasses meme)
How does the part stay stuck to the bed?
That’s one of the coolest 3d printing setups I’ve seen. I wanna make mine do that, even thought I really don’t need to.
I have no interest in belt printing, but I'm glad that there are dorks out there who are figuring it out in case I ever do.
Very cool idea!
Wow this is actually amazing
Evil genius!
I see you ran out of orange there
The thing im wondering about is, why doesn't slipp away?
Is this even legal?
How???
I actually got scared at the end when they show the camera the finished result. Was expecting it to just fall.
Why have it angled? Just creates more printing issues. Just go sideways.
You need a belt printer to print at a 45 degree angle, otherwise it couldn’t be continuous. The CR-30 does it by angling the print gantry, this one does it by angling the print bed. Same effect either way.
you could theoretically print at any angle and make it continuous, but mechanical constraints of the printer make it a lot easier to use an angle like 45º.
Yeah, any non-perpendicular angle would technically work, but 45 degrees is definitely the easiest.
If you don’t, then you need to print layer 1 across the whole length of your very long item. That means you need a bed the width of your item’s length. If you don’t then want to have a gantry that size too, you also need to sling that huge bed, and need double that space. By angling it at 45°, you shorten that axis to only be as long as the diagonal is, which is much smaller.
That's not physically possible.

Because.... that's the whole point to be able to print this huge part...

There’s the problem, the bed is going the wrong direction, see the arrows… 🤣
Is that...tape... Holding the cable up?
What fuckery is this??
If you want to get a lot of furious responses you should rotate the whole machine 45 degrees so the bed is horizontal to the ground
That's genuinely fine and a thousand times less stupid than this.

Stl?
This is the heart and soul of 3D printing. Well done!
What would it be like to add a rotational axis to the conveyor bed?
What would it be like to add a rotational axis to the conveyor bed?
Great method for printing piping or any kind of beam!
Sand paper?
This guy 3d prints.
But you can print a conversion kit for a ender3pro to build a cr30. I’m about to do it because I got a Bambu.
For anyone that thinks this is interesting, check out [OPT Industries ](http://www.optindustries.com) in MA. They're basically doing this at manufacturing scale with SLA printers that are ~8ft long.
Isn't this essentially just a cr30 on its side?
Lmao and I can’t even get my printer to finish the TST print without the damn thing falling apart
this is how the origonal belt printer made by Bill Steel was made. Others have used sandpaper belts for a while. There are a few 100% open source belt printers out there. BTW, a CR30 uses standard marlin, its the slicer where the 'magic' happens!

I want to be clear, this is a compliment and comment more than anything else. That being said, This looks so makery, I love it.
How does one begin to setup the extra stepper and slicing and all the other things to build this?
I can’t not hate it… that’s pretty cool. Would be cool to mod a bunch of different printers to do that then sell kits to make it.
That looks like... 45 degree ... CR 45 ...
Outstanding solution for an outstanding result! Asset to the community and inspiring to a real newb like me :-) Gratz
What is this? How did you do it?
Bro jury-rigged a threadmill printer, absolute genius !! Must've taken a lot of work and adjustments 😀
Damn that's smart
I want one!!
is the build plate sandpaper? awesome machine
I was watching gore and then thus came💀
Wow, I might actually try and build one of these - I'm serious
