Fully automated 3D printing using REAL print beds!

Sure, there are solutions available that promise "automated" 3D printing - but they all fall short when they need to print particularly thin or warp-happy parts. So I set out to build a system that uses real magnetic beds and is able to automatically swap in a fresh one in after every print. And I'm happy to report that it works flawlessly!

[@ArtificalSUN]

TL;DR: Use cams to lift the print surface from the bed, they are powerful and compact Consider the following idea: you have a magnetic printing surface just like one you already have, but a bit larger than the actual heated bed and with a RIGID frame (similar to your design). Then you have two camshafts running along the parallel edges of your bed (preferably the long edges) below the print surface level. Shafts rotate, cams engage the print surface frame from below and lift it from the bed, then you push the old print surface away using a new one coming from some magazine, like you already do. That would be a much more compact system, camshafts will take less space than this whole jack (awesome design but still) and you can use larger print surface and much more Z space.

[@nukularpictures]

Well he could also just use some small pneumatic cylinders like the mgpl12-10z on the sides. Would also easily fit inside the envelope of the printer and still be able to hold the entire bed. Just one on each corner. Would also be faster. I guess there are a lot of options on how to do it. I mean he could also just keep his current design and just increase the extrusion length on his z-axis. That way he would still have the same z-travel.

[@ArtificalSUN]

@@nukularpictures Well, pneumatic cylinders are nice, fast and powerful, but you will need a whole pneumatic system with a compressor, small reciever, solenoids, etc. For cams you just add a motor or two (probably geared or with a belt reducer) and they are powered and controlled just like the other motors on your printer. But I like the idea of pneumatics, might as well use the system for berd-air style part cooling.

[@ArtificalSUN]

@@nukularpictures actually, my next suggestion was to use cams (or pneumatics, why not) to support and lift the actual rails which the "cartridges" are sliding on. Just locate these rails along the bed edges and below the "cartridge" frame.

[@martylawson1638]

The 8mm lead screws with some reduction are plenty powerful. He'd just need 3-4 short lead screws, and a belt reduction or larger gear ratio stepper.

[@ArtificalSUN]

@@martylawson1638 Actually, I just thought that just a couple of small servos with cams would be enough. They are already geared and should be powerful enough, you just have to lift one edge of the spring steel sheet so it detaches the bed (rigid frame will ensure that), then it should slide off the bed easily.

Wow, that is amazing. Nice work! I'm curious as to your thoughts on the complexity of this solution versus a robotic arm that swaps out magnetic bed sheets?

[@soaringbob]

It is surprising how minds sometimes have similar thoughts. When you first described the goal, my thoughts were of a treadmill bed made with a revolving flexible magnetic PEI coated print surface. As a part finishes printing, the bed would advance to the next clean surface. As parts rounded the end of the treadmill the radius would break them loose from the bed and into the collection bin they would go. Cleaning the print surface for the next job may present another problem in need of a solution, but if the goal is to just keep the printer busy overnight, or for longer periods, just make the treadmill long enough so there is enough clean surface to last as long as needed! Then when you introduced your stack of individual print surfaces my thoughts jumped to the need for a magazine to feed them, and that's just what you came up with!

Add that with a metal wiper razor blade or thin heated wire to remove prints on the outside and it could print infinitely. Great job!

The Quinly automation software can save makers time by not having to interact with the process. Maybe next time try something first hand before making off handed comments.

Maybe use permanent magnets to stick the beds. For release use electro magnets that works "against" the permanent magnets. Pros: no power to hold the bed, "failsafe", ... Cons: electro magnets must match the holding force of the permanet magnets, maybe closed loop control and hall sensors needed,..

"this simplified, practicalized version" Ya know... 3dQue is more simple. It has Quinly software to provide the automation of individual g-code files. It has reduced part count to enable automation. It is more practical, because you don't have beds and parts falling together, and you don't have to reload a "bed magazine".... Oh, and you don't sacrifice any build volume. I really think you over engineered this. I'm an engineer. I've been there. I recognize it.

What a brilliant idea! I love how this mechanism has a gravity-fed hopper for the beds and a heated bed that is separate and can move up and down. I think the dead space could easily be removed by having the hopper closer to the bed in use and by changing the design of the belt so that it has hooks instead of blocks that can still push the bed once the first hook has rotated down on the pulley. Also, I'm slightly worried that the 3D printed holders for the bed would warp over time as they are by a heater for quite a while. Well done on having such a great idea and executing it so well! 💜

[@markusstaden]

Very interesting! We had a pretty similar problem definition in university last year, but with a cartesian machine.

This opens so many possibilities! One obvious improvement would be to plan on using this while building the Voron, and modifying it so you can use the full z-height. Would be fairly simple, just move the electronics somewhere else and replace the base with your contraption. Plus it really needs a ramp where the done prints come off, I can see the piling up beds to cause problems, not to mention a fragile print would be likely to break (I know your version is just a proof of concept, so not really necessary)

[@kevfquinn]

Cool build! On the ejection side - a simple slope would allow the ejected beds to slide out neatly. A thought on gripping the bed inside the printer is electromagnets - steel flex bed sheet, electromagnets in the heated bed plate itself - could be a lot slimmer height-wise.

[@antiundead]

Excellent video Tom! Finally a proper tackle of this printing challenge.

I've thought about that - and the Voron (and similar) printers would lend themselves to that very well. The electronics compartment at the bottom feels like it's mostly the size it is for comfort and ease of use, no reason it couldn't be smaller or tucked away somewhere else on the machine.

WOW, i don't know how you do this, but you keep suprising me with so cool Projects that i want to build for Years that i cann't be more happy with the Content that you kepp and keep making! A HUGE thanks for that! Content Creator Nr. 1! 👍

Looking forward to see what you do next with this idea regarding to slimming it down and increasing the build volume.

[@craigrmeyer]

Sir! Your skill and fluency with rolling your own DIY movement stages out of shafts, bushings, screws and whatnot is awesome. I had no idea this was possible. You must be saving a fortune. Where do you shop for the metal bushings/screws/shafts/etc. that you pressed into the 3D printed pieces?

[@BRUXXUS]

This is so wonderfully bonkers! I love it! I just wish there was a little slide on the output so the beds don't crash off the edge each time.

[@mrclown7469]

Amazing project, Tom! The conversation on the podcast a few months ago about continuous printing made me assume you'd just go with a belt. But what you've dreamed up instead is next level! 🤯

[@badijks]

I like your idea and how it turns out. You could also integrate it in to the frame of the printer to save height and maybe place the control bords and powersuply somewhere else

[@TasosKatsaros275]

That's awesome! Kudos to you for supporting printers like Voron

[@JohnOCFII]

Excellently creative way to swap beds automatically! Great proof of concept and great job with the video explaining the process.

[@goeckerd]

Great job. I've been wanting to do something like that for 3 years now. Nice to see how the Voron 2.4 makes it possible.

[@JN2023]

Looks great! When space around the printer isn't an issue, a rotary system is usually the go-to solution within automation. Then again, picture a robot arm in the middle of a circle of 3D printers stacked in layers, serving seven times three 3D printers simultaniously, while putting the printed pieces in different bins, including a red bin for failed prints. Perhaps it also adds some need for DFM (Design for Manufacturing).

[@AlexanderEresov]

Interesting idea! And I must side with others here: truly great way of presenting your sponsor, wish everyone do it this way

[@ralmslb]

This has given me a great ideia. Since the Voron uses a magnetic bed, I can just use a robot arm that switches the bed metal sheet between prints, not sacrificing anything in terms of volume or proven stability of the Voron. Thank you for the great video

[@joe4264]

I am in awe with your work here Mr Sanladerer, excellent work. Thank you for making this video, it's got me so inspired, so much so I am away to plan my own Voron build and plate change system. Kind Regards, Fellow Engineer, 3D printing Enthusiast and Inventor.

[@Steve.68]

Absolute genius. Please carry on developing this idea

[@RomanoPRODUCTION]

The sponsor sequence has been super pro. Good Job Thomas 🎯

[@lukedavid8099]

Looking forward to v2!!!! Love the latching mechanism

[@timha4102]

You‘ve got to love the precise amount of overengineering :) Well done / Gut gemacht!

[@TheWill695]

I did this years ago and just used the 3d print head to push the prints off the glass bed and then used a queue system in octoprint to print the next print. it's been working for the past 4 years great and i didn't need extra bits

[@allenpaley]

Just re-watched this gem of a classic. This video gets the credit for convincing me to level up my 3DP parts crib. 💸

[@sriramneravati5048]

The implementation of this prototype is super well done! Love the bed popoff mechanism super satisfying to watch.

[@bohdanshcherbak6303]

Great! Can wait for the slimmer version! Really looking forward to make one for my 350mm build
