MOST POWERFUL 3D PRINTER BED EVER (lifts human) - GIANT 3D PRINTER BUILD PT. 2

[@Engineezy]

That feeling when you realize you need to disassemble EVERYTHING 😅 epic build, so impressive. Let me know when you’re ready to sell them 🙌

[@ivanmirandawastaken]

Thanks!! we all have been there, it's just a matter of scale 😅😅

[@SteveSiegelin]

I was in the comment section when that part came up of how to add an extra 30 mm🤣.... that was pretty great, to do so I need to and then he disassembles the whole machine! I love engineering! There's always that one little part you forget that cost you hours of build time but at least you've gotten the rhythm of putting it together now!

[@3DELWORLD]

Amazing Project, waiting for that big benchy on lake in your next thumbnail 🔥

[@simonl7784]

10:15 since you seem to love it when it's all pretty and neat, may I suggest you add a ferrule crimper to your tool arsenal. Though there is no issue with the way you did your wiring, it just looks so neat with ferrules and it's cheap to buy and use. Love your videos Ivan, I can only imagine your colorful cursing after your minor setback lol Have you considered using Klipper firmware? at this size, your printer would greatly benefit from advanced features like input shaper. Cheers!

[@thomasschoonwater3390]

He's using a duet, so he already has reprap. I don't know if klipper would add many functions then

[@dadjake]

Agreed. The Duet has some very good features on its own, but Klipper adds a lot for relatively little money (if you can find a Raspberry Pi for MSRP these days). Only thing bad about Klipper is the community around it.

[@simonl7784]

@@thomasschoonwater3390 Klipper will run a Duet with a Rpi or other powerful SBC plugged into it. The main reason I mentioned Klipper is because the larger the frame, the more it will suffer from resonance and Klipper has a function called 'input shaper' that is designed to compensate resonance; which produces nicer prints at faster speeds.

[@Dramaican88]

@@simonl7784 RepRapFirmware 3.4 and after for the Duet boards already has input shaping and accelerometer support. Has had the web interface and easy firmware editing via gcode config files (.cfg for Klipper -> .g for RRF) without the need for a SBC or a Rasberry Pi for years now. For this build I think the Duet board chosen will be great and more than enough. Are there any other significant features that are Klipper only?

[@-vermin-]

Ivan I am constantly amazed at your productivity. It takes me forever just to add drag chains to my laser cutter.

[@thomasbonse]

With that size bed, I would've recommended a rack and pinion drive mechanism rather than a belt, which is prone to stretching under load. This is of particular concern, given the dynamic nature of the load as you print.

[@csorrows]

These high quality steel belts will do just fine at that huge width. Other parts are going to bend before any damaging amount of stretch happens. I'm sure he is going to use leveling on his bed which will compensate as time goes on. Even if they do stretch over time, it's going to be a slow process over time that will not make a measurable amount of difference during even a week long print.

[@thomasbonse]

@@csorrows I'm not talking about stretching from one print to the hundredth print. I'm talking about during a print. Even just a small amount of stretch, in the region considered negligible by the manufacturer, can result in dimensional changes to the printed part.

[@davincifpv3842]

@@thomasbonse I guess your concern is valid. But you have to think in an all difetrnt direction. This printer is so bigg, you have to be happy if you have mm accursce. I mean even centimeters would not be crasy noticabel in the end

[@frollard]

@@thomasbonse On a traditional printer perhaps sub-tenth-mm matters for extrusion on a 0.6mm nozzle...this machine won't be making layers that thin, and any dynamic loading will vary proportional to the print progress, so any stretch on the belt will be proportional to one layer of print, barely changing anything. Worst worst case is the software needs calibrating that the final height be off by a few mm for a hundred kg part.

[@thomasbonse]

@@frollard You're assuming even loading of the platform, which is not guaranteed. This is one of the reasons why even cheap and small printers don't use belts for the Z-axis.

_Damn._ That is one heck of a demonstration at the end! I mean, with the bed already weighing in at a positively _chonky_ 15 kilos, I wasn't too concerned with it being able to support what it was printing...but _wow!_ As always, I appreciate it when experienced makers leave the mistakes and setbacks in their build videos, it inspires and reassures people who _aren't_ crazy top-tier makers to see that _everyone_ makes mistakes. 👍

[@strictnonconformist7369]

[@uweploeger511]

Hi Ivan, great build till now but even the steppers are strong enough I would recommend a counterweight for the bed🤔😊

[@Insane_Kane]

i wouldnt worry about the steppers, 4 high quality nema23 with a 43x or whatver it was reduction have enough torque to lift several ivans :P

[@XTJ7]

@@Insane_Kane Not sure if I did my math right, but not accounting for friction and assuming nothing else in that build will fail first (which it probably will), the 4 motors at 60nm each, assuming a pulley diameter of 3cm, will probably lift somewhere in the neighbourhood of 800 kg. Quite a few Ivans.

[@jonasstahl9826]

@@XTJ7 You need to calculate with the radius not the diameter means you need to do the math with 1,5cm not 3cm, it can lift 1600kg.

I think is not a 3D PRINTER, it's an elevator. I like what do you create and I think your are the most people to create a giant 3D PRINTER.

[@Haddepe]

Hey, hi, a good way to stiffen a square is to use steel cable under tension instead of the threaded rod. Its easier to install and cheaper.

[@SteveSiegelin]

Cables work but they don't add as much rigidity as thread all. Cables will also allow vibrations to transfer to the frame more readily. Thread all gives you the ability to use them like iron rods but also the convenience of adjusting the size without having to cut them. It's a more rigid design using the thread all and that's what you need in a printer. We use cables in aviation because they are lighter and they allow for Flex. Flex is the enemy of this machine

[@whyme6742]

Why lift the bed at all? I would have lifted the gantry like the vorons do, this way you are lifting always the same weight and won't get issues later with flex due to increasing weight the longer the print goes. Yes you demonstrated that it is able to lift your weight, but what about the flex of the bed?

[@Thor_Asgard_]

Not crimping the cables triggered me hard ^^ you are crazy talented.

[@Psyphuck]

Saw the first video and immediately was looking forward to the finished project, best of luck!

[@MegaDada1995]

While the system can take the weight, once you sit down you can see the whole bed move down a little bit. That is the belts stretching and might result in accuracy issues with larger prints..

[@FilamentStories]

[@jamieh6084]

Suggestion: Adding a small second z axis on the print head that just does z hop moves, might be a cool inovation.

[@AdrianStaicu82]

This needs to be done in software and in firmware, but it might be possible with some enable/disable commands for start and end of each layer. Basically switching motors on and off or using a relay to switch their step signal.

[@glowpon3]

I would still add pulleys and a counter weight to it just to lower the strain on the motors, and make them less likely to fail and drop. Still, can't wait to see it operational.

[@NickBiancalana]

Ivan, minor critique... The Z belt tensioners would be better on the bottom of the belt runs so that the tensioner blocks and screws weren't the elements holding all the weight. Probably ok now that it's in, but just a thought for future consideration :)

[@tozpeak]

If you ever decide to build even bigger printer, try designing a bed with counterweights (like an elevator). It allows to have better control even with weak motors, since they operate on weight difference. I've seen a dremel cnc with this approach, it worked fine.

[@AgentWest]

That is a great idea for something this large. Some industrial CNC machines do in fact use counter-weights on cables, others use springs or even air cylinders to compensate for the weight. Often times the movable part weighs several hundred kg, so the compensation systems really do help.
