GIANT DIY 3D PRINTER FROM SCRATCH

In this episode I make the frame and mechanics of a giant 3D printer from scratch, why? because I need to print something really big for an incoming project. It is a Prusa clone and I'm pretty happy how it is looking right now. I will do all the wiring and programming next and hopefully It'll be back on this channel soon.

[@andrewy2957]

I'd recommend adding a support across the middle of the bottom of the mirror. I feel like that much unsupported glass could cause the mirror to bend slightly and could result in an uneven surface. Love the design though!!!

[@markswayne6326]

For a bed this size it might make sense to move the gantry back and forth instead of the bed. That mirror has to weigh a zillion pounds (that’s about half a zillion kilos)!

[@ivanmirandawastaken]

"Make sense" is an extremely ambiguous term. The mirror weighs a zillion pounds though, you nailed it.

[@GlaucusBlue]

exactly what I was thinking, that mirror + the weight of the print, is massive. tahts a lot of weight moving around especially on belts, would have been better having the mirror on z with a couple of ball screws, and nozzle on x and y. That's what I'm currently building but 400x400 although will take a while, buying a couple of things a month. Titan aqua is expensive. also cant decide what board at the moment, do love the duets interface over marlin, but they are expensive.

[@gerleimarci]

You definitely need an E3D Supervolcano for this.

[@ivanmirandawastaken]

In the mail

[@harviecz]

FDM printer time is dependent on volume, which is third power of printed object height (=not really scalable). Resin printers on the other hand take time proportional only to object height itself (=lineary scalable)... The printing time of "Radon transform 3D printers" is (theoreticaly) not related to the object size at all (=very scalable). So i guess for very big prints we will need to change the technology (as long as we're not willing to go with huge nozzles, eg. like they did in concrete casting 3D printers)

[@Chlorate299]

@@harviecz large volume SLA machines have existed for quite a long time, I've personally had some entire gearbox casings SLA printed... The issue isn't scalability, the issue is material properties - SLA resins produce nice smooth surfaces but they're incredibly brittle and have terrible thermal properties. FDM carries a fairly huge advantage in the diverse range of materials that can be printed.

This printer will forever be known as the "Crazy Ivan" and nothing can sway me from this point of view.

[@YanouFishel]

You might want to put a cross-brace in the middle of your "mirror-carrier" so it wouldn't bow in the middle over time. Maybe also upgrade the belts to 9 or 12mm. The bed weights a lot probably and you've done well by using 2 motors to drive it. However, the belts (given they are the standard 6mm belts) will stretch a lot faster by slinging that weight :P So bigger belts can resist the higher torque, resulting in less slack over time, and better prints! Nice job however :D Already looking forward to the next 5 videos!

Ivan, you are insane...insanely awesome build!

[@duinishuodedui4999]

Seems like a decent design, it will probably work fine. A few thoughts though: add some kind of wooden plank under your mirror: it will not prevent much from sagging, but it will help to protect the mirror in case you jam the extruder into it, which can happen and did happen to me on my giant printer, especially during calibration. Better add a few more aluminum profiles under it too, on such big surfaces you can get pretty big sagging, like over 2 millimeters, which obviously doesn't help with first layer adhesion. Other than this I'm pretty sure it will work fine, nothing wrong with it :) Even if the Z axis looks flimsy, I bet it will not be an issue, most people put too much efforts in frame rigidity while it actually doesn't matter all that much, except for very high speed printing. Giant printers do work very well, much better than most people would guess, and that teaches a lot about what actually is important to get good printing results on a 3D printer. Good luck on the rest of your build!

[@PaulLemars01]

Well, this earned a subscription. Totally not sure about this design though. The largest heaviest part of the printer is doing a large part of the work and I think that is going to cause you big problems. Personally I would have gone for a large scale delta or a coreXY since both of those regimes have the lightest part doing most of the work. I know a Delta is funky and hard for a lot of people to get their heads around but the upsides here is that you can make the bed out of anything and it's not a factor. making the towers super rigid is also not an issue since they also don't move. That just leaves the actuators and carbon fiber tube is super cheap now. You could run the whole thing with standard belts and Nema 17 motors since your entire focus is making the print head as light as possible. Code is easily available to run them and the only potential downside is you are printing on a circle instead of a square. So I've got my popcorn, let the fun begin.

[@endab5517]

On the printing bed leveling: with a larger print would the weight of the print cause it to go off level?

[@StopChangingUsernamesYouTube]

Absolutely. I think there's probably going to be an upgrade video or two down the line after that problem comes up. Probably the easiest option would be a diagonal brace to support the center of the bed and restrict sagging to a few cm from the corners that aren't over the brace bar.

[@endab5517]

William Shreckengost I thought he would have gone higher capacity but the sagging might be a minor issue. I was wondering if the spring loaded balance technique will get affected on this with the larger weight and center of gravity shift (as mentioned).

[@StopChangingUsernamesYouTube]

@MichaelKingsfordGray You're right, I was stuck on the bed, instead of the whole Y carriage. It's definitely beyond the means of the kind of springs that'd normally get that job, but lock nuts might be able to do the job well enough. (Though it's definitely a speed cap either way.) If not, it could be down to a fixed bed mount, which is going to take a hobbyist's fortune in measurement tools to set, and linear rails instead of V-rollers to take out some of the wobble potential. Not that I wasn't already convinced, but I'm seeing another good reason to go CoreXY at this scale.

[@Tdub415]

Aren't you going to need some support unde rthe middle of the mirror? I woudl think due to the size of it, you're going to get some drooping.

[@MegaKencam]

I'm always impressed with your skill as a designer. I do agree with the others who have concerns with the weight of the bed. However, this looks like a very specialized printer. You will need to print slow but with a large head it should still out perform a smaller unit making smaller parts that need to be assembled. A print failure with this thing will potentially be very bad though. I wouldn't worry with the bed adjusters. Get it close and lock it in place. With a bed that large you will need a BL Touch anyway.

Easier than this... Someone would need to show me

[@lukedavid8099]

Easier/cheaper to replicate, no. Easier to achieve a better, more consistent print quality, yes. However, knowing who is building this monstrosity and what it's going to be used for this should work just fine. Also he's going to be using at least a 1mm nozzle instead of a 0.4mm standard nozzle so quality shouldn't be too much of a concern.

@@ivanmirandawastaken you could mount the bed into 4 threaded rods or something like that (would give you electronic leveling by default), and use that as your Z axis, the whole bed slowly moves down with gravity. Then, the hotend is mounted in a way that one axis is fixed to the chassis of the 3D printer (say Y) and the other (X axis) rides on top of the other one. The hotend would be mounted to the latter axis. This is (to me, personal opinion) a tad harder but way more reliable. It will help reduce ghosting and increase print speed and acceleration, which in a bed as massive as that one are quite important factors. This design, though, will work just fine, and it comes with a big advantage; it's already done.

@@ivanmirandawastaken You 100% need auto bed leveling ivan the glass will sag a little in middle get a bltouch they are what you need

CoreXY would mean you need to move this humongous printbed up and down, perfectly level. Or you put the hotend on a Z axis, which I haven't seen that often, either...

Daaaaam, this channel is next level 😂😂 other modding thier 3d printer but this guy upsize to the max 😏👍

I was going to be worried about how heavy the bed was that may restrict fast movements, but when you said super volcano I realized it won't be moving fast, just printing BIG
