Endless 3D printing - DIY conveyor belt delta bed

[@TeachingTech]

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?

[@98f5]

can u make it move back and forth on the belt axis to print bigger things?

[@marcusmarcusk830]

Now you just need to combine it with the FlSun V400.

[@techdiyer5290]

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. :)

[@logan317b]

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

[@Peter_Schluss-Mit-Lustig]

This might be the perfect use case for nonplanar slicing to make these machines capable of infinite prints as well

[@EGGSHL]

Ohhhh god i wish that was already possible

[@H3xx99]

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.

And now I finally have a use for my old delta. This is incredible dude. Love the work. Thank you so much.

[@MAGA_Patriot2024]

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! 👍🙂

[@skrimp9919]

@@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.

[@stevesareyka8636]

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.

[@markferrick10]

Very very kool. I like that you used a delta printer. I don't need this, but I WANT it. Thanks.

[@JonS]

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.

[@Mueller3D]

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.

[@JHenley01]

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!

[@andymuzzo8568]

That’s awesome mate. You should call it the “Endless 3”

[@L337f33t]

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!

[@tannernewton8543]

I was googling to find inspiration for this exact idea!! Happy to see all the work is already done for me haha

[@JoeSnow-yb8kx]

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.

[@1stWorldProblemsSolved]

Using the printhead is the best method imo. Less shit to break...I've had this for 8 years now...lol.

[@techscout5710]

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.

[@mgrabo1024]

I was just thinking about adding this same comment

[@Coltography]

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.

[@feliwein_cc]

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.

[@roysigurdkarlsbakk3842]

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.

[@muddhaptab6347]

This is really tempting to build and addressed the main reasons I have resisted the urge to get a belt printer.

[@zora_tech]

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 😁

[@shenqiangshou]

[@milanpeeters6305]

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!

[@paulg3336]

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.

[@bakercat1461]

[@AnIdiotwithaSubaru]

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.

[@JN2023]

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).

[@nicholasneuwirth]

[@maagbrasil]

[@ototheo2740]

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

[@0LoneTech]

It would be partially tighter, but the curved plate sides mean only across the centerline. It would likely make it self track.

[@SeanTaffert]

Better to put a lifting mechanism under the build area and lift the plate up slightly while printing.

[@bradleyswanson329]

one cool mod idea would be to put a blower fan inside of each part eject ramp to help the separation with thin parts. Also it would not be hard to set up a homing macro to detect the tape, this could be done with some magnetic tape or a little bump pushing a limit switch.

[@neilbradley5968]

I was thinking something similar. It would be easy to calculate or even measure the length of the belt and just change the eject distance to this value. But then you'd always be printing on the belt in the same place. 🤷‍♂

[@boojiecentoobie4272]

@@neilbradley5968 you could change the macro to randomly place it on the belt ( with the requirements of a certain distance from the tape).

[@martylawson1638]

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.

[@javeronh.3996]

likely way too much programming pain but maybe for the purge an option would be you could have it run a certain distance, the width of your build volume, then start printing again. it looks like this would put the printed part in a good area to cool down while the new part prints. making it so you may not need active cooling. another option that may be neat is since you are using steppers for the belt you could adjust the purge such that it completes a half lap (find the distance by trying to have it do multiple laps, count the steps it said it did, then divide out to get a good number. I think). by doing a half lap, and getting a large number and dividing, you should be able to pretty much guarantee that you will never land on the seam. the second option may make it easier since it keeps from printing on the seam, whereas the first idea there is a good chance of printing on the seam

[@WhyIsItSoHardToMakeA]

Honestly I like how you can, in theory, make 2020 and other sizes of aluminum extrusions to whatever length you need. Obviously not the best print orientation but should be adequate for a desk frame depending on your filament and slice settings

[@jellopoolparty7112]

Pretty cool.

[@TheNextDecade]

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!

[@sonosus]

Onshape now has a Frame feature that does exactly what that plugin does but built in.

[@confusedtx5]

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

[@RagingShrimp67]

Cool design, but What I really like about the 45 degree and custom slicing design is that you can get basically infinite Z height, which is not possible in this case. So this works for many small parts, but not for few long parts. Also on the 45 degrees you can print 1 part at a time so it's not necessarily causing failures in all prints if one fails.

[@MAGA_Patriot2024]

Not that I'm disagreeing with you, but if you orient the model properly in the slicer, can't you just swap the infinite z for infinite y?

[@RagingShrimp67]

@@MAGA_Patriot2024 In theory yes, but it takes more than reorienting the model, you need to customize the slicer quite a bit, and I would also be worried with depositing plastic vertically rather than horizontally, I don't know enough to say whether it will work, and somehow affect layer fusion/failure rate.

[@MAGA_Patriot2024]

@@RagingShrimp67 I certainly see your point. 🙂 There is definitely the possibility of needing huge amounts of support material near the "top" of the model where none would be necessary previously. My purposes require large z models, so it looks like I have no choice but to go the 45° route. I appreciate your input though...thank you! 🙂👍

[@MarcelRobitaille]

Couldn't you make the eject macro make a full rotation of the belt to avoid the tape issue?

[@JohnMGibby]

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.

[@MarcelRobitaille]

@@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?

[@paulg3336]

If you want to increase the rate of those springs , shorten them by cutting ,and add a spacer to make up the length. A shorter spring (less coils) is stiffer
