Endless 3D printing - DIY conveyor belt delta bed
ฝัง
- เผยแพร่เมื่อ 6 พ.ค. 2024
- Since I tested the Creality CR-30 Print Mill, I’ve wanted a 3D printer that could eject finished parts and continue through a print queue autonomously. In this video, I take you through how I converted my FLsun Super Racer delta 3D printer to do just that. Everything is free and open source. A separate video is provided to cover the step by step assembly.
Still some work to do to make it foolproof but as a proof of concept I’m very happy.
Thanks to Adam from Powerbelt3D for offering tips and advice in my design process. Thanks to my patrons for assisting with the list of part ejection capable printers.

Thanks for all of the feedback and great ideas. I still intend to keep it fairly simple for my printer but perhaps someone will remix the design to take it some place else?
can u make it move back and forth on the belt axis to print bigger things?
Now you just need to combine it with the FlSun V400.
The best place to put cooling fans would be under those ejector prisms, and you might as well redesign those just to cool the part through the crack. :)
After seeing what the angled conveyer belts can do, I thought “Why not just have a flat conveyer bed for infinite prints?”
You have done an amazing job at making that vision a reality
This might be the perfect use case for nonplanar slicing to make these machines capable of infinite prints as well
Ohhhh god i wish that was already possible
You can look into the Enraged Rabbit Carrot Feeder (ERCF) multi material modification to solve the lack of filament problem. It's an expandable automatic filament feeding system that can be used to either change colors and materials automatically, or replace empty filament with a full roll.
This is fantastic work Michael, but you could improve it and make it truly endless for 80% of 3D printing use cases, by adding:
1. A camera photographs the part
2. Photo is posted on social media
3. Part is fed in to a chipper
4. Chips are fed in to a filament extruding machine
5. Recycled filament is fed back in to the printer
Of course this wouldn't be useful for the other 20% of uses. Namely: 15% printing parts for printers, and 5% parts to give away to friends and family.
You just need to add a step 2.5: Based on Likes/Dislikes, direct part towards chipper or towards "keep" bin. You could use a servo with a guide bar at the end of the belt to send parts one way or the other.

Comment of the century.
I run a small print farm so a belt printer like this has always been the holy grail for me. I built the PrintShift for the Prusa Mini and the issue I had was the flexibility of the belt allowed the parts to warp too much with PETG. I would guess this design would have the same issue. Hopefully that issue can be solved at some point. Great work though!
Honestly this made me excited to save up for a new printer.
I like this design as the drop down extruder style feels much more versatile.
Really impressive work Michael, you provide so much to this community, thank you.
And now I finally have a use for my old delta.
This is incredible dude. Love the work. Thank you so much.
When you say "old delta", what specifically do you mean? The reason I ask is I have a qq-s pro delta down the basement, and I'm wondering if that would suffice for the build. Thanks! 👍🙂
@@MAGA_Patriot2024 I have a qq-s pro and while I don't think I would do this build personally, I do believe that'll work quite well with majority of the parts in this video.
Amazing work Michael thank you so much for sharing with the community much appreciated
I was googling to find inspiration for this exact idea!! Happy to see all the work is already done for me haha
Awesome project, props for the development efforts, well done. Thank you for sharing and keep up the great work
You could maybe introduce a slight vacuum below the belt (with holes in the aluminium plate) to increase the tension between the belt and the bed. I think fan(s) should have enough power for that purpose.
I was just thinking about adding this same comment
Adding the system from the Bamboo x1 carbon to watch the prints would be amazing! A belt printer with the ability to sense if a prints gone wrong would be amazing. It would take this printer to the next level!
I already wanted a delta, now I want it even more. awesome project man
Thanks for sharing, great design. I'll consider adding this system to my CoreXY as it should work much the same as your delta, just with Z homing required after ejection. Being able to automate multiple part production without the 45 degree issue is a game changer.
Pretty smart! Nice design, thanks for sharing!
Wow 🤩 exactly fit my requirement. I want to try Delta and also prints overnight unattended this is perfect 👍 thanks for sharing such a well design and built. You are awesome Michael 💕
Dude this is amazing, I absolutely love delta printers and the concept (I say that as I've not yet used one) of belt printers but like you I dislike the 45 degree print angle, this is definitely going onto my to build list, thank you so much.
Absolutely incredible work!!! Very well done!!
This is really tempting to build and addressed the main reasons I have resisted the urge to get a belt printer.
I was considering adding a delta to my collection. I like to tinker so I may get one and give this a go. Your design seems well though out, very cool !
Brilliant! As always a regular source of inspiration and ideas. Cheers.
..."-Simply because I can"!
Do I just LOVE that expression?
I must say that I just admire that attitude.
Keep up that work, 'cause you're the best source of inspiration avalible , in my humble opinion.
This is AWESOME stuff. Nice work!
Yes, wow, looks very interesting. I'm glad people are doing these mods.
very nice work! and thank you for open sourcing it!
This is rad. I'd never need it, but I love the ingenuity. Great work!
Wow! this is awesome Michael.
Nice jacket, I was in Italy when the crash happened. The whole country was in mourning.
That’s awesome mate. You should call it the “Endless 3”
Very excited to try this project!
Great project, thank you for sharing!
Very very kool. I like that you used a delta printer. I don't need this, but I WANT it. Thanks.
That works really good,I call that a success. good job 👍
Great work as usual.
Amazing work!
Superb work, love it
Thanks for this one. I was thinking about building something like it some time ago, just a wee bit different. In my design, I wanted to print a part at a time and roll the belt over to a cooling area, continuing printing from the queue, but letting the last print stay untouched. This would, in theory, reduce the temperature on the recently printed part to something around room temperature and thus make it release from the belt without problems with stickyness or deformation (at least theoretically). In this design, you'll have a single bed heater, but only under the area to which the part is printed, but not on the lower or "souther" region. This will require a longer belt, but not a whole lot, but it'll let you print even faster, since you won't need much of a temperature drop before continuing on the next part(s).
PS: These are all my own ideas and they are as of now, april 23th 00:00 CEST, released under open source.
I would suggest a BRUSHED surface at the end as well as the exisisting ramps to pick up finer parts without introducing drag to the belt, kind of like the edges of an escalator! Also some big blowers that turn on during ejection would look so cool, kind of like a car wash at the end. LOVE the execution and idea!! Can't wait to see more of this.
This is incredible
AWESOME! Congratulations!
Amazing I really like Delta printers but because the firmware wasn't mature and after Core XY printers came out they are not very popular. Luckily Flsun is still making some new delta printers. Also I have found some videos of people making large deltas but they are hard to find. So seeing this video makes me really happy 😁
Awesome work Michael!
Nice! This printer turned out very nice and impressive! A+++
NICE BUILD!
Using the printhead is the best method imo. Less shit to break...I've had this for 8 years now...lol.
That looks so cool
Great video and good job man
Super cool! Thanks for all the effort :)
Beautiful mate. Top darts
Super racer with this mod is super amazing!!!!!
Awesome build!
You could add 4 small adjustable rollers on top of each corner of the bed to add extra pressure on the belt in order to keep it squeezed against the bed underneath 👍 quite simple and worth a try in my opinion!
Amazing work. Already in my folder of ideas for what printer I get next. Looks like Duet/Rep-Rap could do the ejection just as easily, though I think it doesn't have input-shaper auto-tuning yet.
I think you could use an optical end-stop sensor to sense the tape on the print belt. (or a bit of retro-reflective tape applied to the belt) That way the "Eject" macro could do one full loop of the belt every time and avoid ever printing on the tape.
Excellent Build!!!
Nice mod and thanks for making it open source!
Another excellent video.
Maybe making it so the printhead hovers over the print for a min or two with just the fan going after the print is finished before rotating the belt it would cool it down without you having to implement any new fans or coolers, also after every print maybe spin the print bed entirely so that the adhesión later is never printed on, for the rest I'm extremely impressed didn't even know anything outside of 45° printers were able to do this. Keep it up!
Nice work
Awesome video!
Michael, that was brilliant. A MK3S version would be phenomenal 😉 Cheers, JAYTEE
now this is my type of designing
13:37 An alternative to using belt tension to achieve this , which is a game of diminishing returns, consider using vacuum to suck the belt to the bed.
I have an automated microscope slide cover slipper that I service , the slides are held on the platern by vacuum. the vacuum is generated by a computer fan in a sealed enclosure that generates a small negative pressure and this is connected to the platern by tubing.
Great video!
AMAZING VIDEO!
fuck i've been wrapping my mind around a continuous printer for a couple months for now and reached to the conclusion that this if the better setup for speed and durability, super sharp man.
Wouldn't lowering the ilders and slightly increasing the belt tension help with the slight wobble ? That way the belt should be somewhat pressed onto the bed
It would be partially tighter, but the curved plate sides mean only across the centerline. It would likely make it self track.
Better to put a lifting mechanism under the build area and lift the plate up slightly while printing.
This is super cool! I may have to look into this :)
Looks cool bro!
Awesome stuff 👍👍👍
This is fantastic!
As the belt is stationary while printing, the tape shouldn't be a problem. Just add some white paint on the underside of the belt in 3 spots and ad an opto-reflective sensor outide the print aerea to sense it. After any print just move the belt until the next while spot is sensed. So the belt only has 3 defined positions - and you make sure the tape is never on the print aerea where the tape is.
Actually if not using klipper, you can make the belt movement by a seperate controller. You do not even need a stepper driver and -motor, but you can use a double-h-bridge and every dc-motor strong enough to move the belt. You need just an input which triggers movement to the next marking.
Most printers have an unused IO and you can set Pins even on classic ramps-boards by gcode to give the signal to move the belt (m42 - as 42 is the answer to everything(. In gcode after signaling the belts electronic to move the belt to next position, just add a wait for the time needed to reach the next position (G4 P ).
This way you can add your belt system to any delta ore cubed printer, just using a classic arduino and a h-bridge.
Of course you can do this also with a stepper motor and -driver. As seperate controller I recommend using a ramps.based board flashed to arduino bootloader. As the belt should move slow and only after one print is finished, an allegro driver is ok, so you can use any ramps based board like the old creality non-silent boards collecting dust in one of your boxes at the moment...
Brilliant
Nice jacket for this weekend.
OMG That is awesome. I want it.
I would love to see this on the voron 2.4 with its flying gantry and stationary bed. There's even an extra pin available on the octopus mainboard for another stepper.
Couldn't you make the eject macro make a full rotation of the belt to avoid the tape issue?
Yeah, I though that also, but wondered if, over time, the belt surface might not perform the same due to using the same spot all the time to print to.
@@JohnMGibby Rotate the belt so the tape is in a different spot under the printer to use up another section of belt? Don't always place your part in the center of the build plate?
Hey really cool Video and Idea, i love to play arount with Belt pronters myselfe for a long time now but dint know where i could buy a beld. So that i now know you helped me so much an game me 2 new Ideas witch i will try thank you so much for that cool Idea and Video. ^^
I've wanted to build a corexy printer for a while now. Given it's already a custom size, I think I could add this idea into it from the start without significantly affecting my build volume
Please continue to iterate and update this. Absolutely love this build I need to build my own!
Cooling fan with shroud at the front of the belt might be beneficial for easier part ejection. It would be cool to implement a new modular heatbed from Prusa to reduce warping/failures.
Pretty cool.
Awesome 👍🖖
this might be a nice add-on to a Voron 2.4 also
There are ways to glue the belt removing the seem entirely (Siegling or Habasit method). Would also recommend an overhang where the belt protrudes and with a scraper on the underside of the belt under the overhang. Also easy to make an automatic mechanic belt tensioner (usually called bow tensioner).
I always thought the reason why the 45deg was done was to avoid patent issues with the old makerbot IP. I used to gave one of those Auto build platforms about 10 yrs ago, shame it wasn't open source,
Thats cool, i love this project. Make more cool stuff.
I super need this
What I would give for you to sell an upgrade kit to the super racer! Amazing engineering work!
Thank you Michael, your continuous Vampire family in Europe loves you!
I like that setup a lot Im looking for a printer that I can print boats in one part instead of having to print multiple parts and gluing them together. This looks like it would do that if I made a support at the end to keep the boat level for the whole print.
Nice Ayrton Senna's hood! Cheers from Brazil!
I am a long time watcher. This is great. Will you create a package ready to buy on this?
Genius
Nice!
Awesome!
Awesome job as usual. As watching I knew you'd eventually mention printing on the tape that connects the belt as an issue. If printing smaller single parts like you showed in the video, couldn't you simply add a line in the startup gcode that set the belt axis to a specific point each time a print started that would prevent any printing on the tape? For larger single print parts (such as a sword) you'd still need a special slicer for that correct? And you wouldn't be able to avoid the tape so I wonder if a custom made belt would be the answer there. Hoping to see updates to this great concept in the future.
Wonderful mod! I have a suggestion for the front roller and removal point!
I hear you say you wanted cooling, and something to prevent the skirts form getting sucked under.|
I was thinking of a curved "finger" blade that sits 3-4mm under the initial curve of the roller that sits very close to the bed, but not quite touching it. The part is hollow in areas to allow cooling fans to be placed in, and at the peak of the finger blade are slots where cool air flows through, cooling the part as it starts to pass over. The pressurized air and body of the finger blade work like a squeegee to effectively cool the bottom of the part evenly and clean the part off the bed without fear of any of it getting pulled under the roller.
Let me know if you're interested in this idea, I'd be happy to mock up a simple design to better show my idea if you'd like!
If you're looking for a good cooling blower fan for getting parts off of that belt you should check out the Delta BCB1012GJ-01. You can usually find them for cheap from the usual places and they have both super high static pressure and airflow. They would be great for a large dual nozzle from above and below the bed/belt. Just be sure you get a clean/new one because people usually pull them from old dead NEATO robots and most of them i have received good/new shape but I did get one that was gross and full of dust.
