GIANT 3D PRINTER FROM SCRATCH - IT WORKS!

It works! The Big 3D Printer MkII is finished and it works beautifully. I made a first test print of a 66mm combination wrench, 800mm in length with absolutely no warping!! It shows a few holes in the top because it has too little infill but hey! it is the first print!! It took only 6 hours but I'm sure that this thing can go way faster.

The post with the files can be found here:

During the recording of this video there has been maintenance work performed on the shop hence the very little speaking and the frequent change of background, lot's of noise and dust.

All the components were sent to me for free with no compromise, I'll list them down below because I really liked them.

The Duet2 was a pleasure to work with, easy to use well documented and extremely robust. Duet3D has released the next version and you can find both here:

The Hemera extruder is an insane piece of equipment, I managed to snap the filament with it trying to make it lose a step. You can find it here:

The profiles were sent to my by a friend of mine, I love them and you can find them here:

I printed every single part of the printer with the PulseXE with not a single failed print, I will probably use it to reprint all the parts with NylonX soon. You can find it here:

-Good morning, I would like to order some filament
-Sure, how much would you like?
-Yes

Congratulations on the build! As a hobbyist 3D printer enthusiast and DIYer, I'm totally in love with this and I can not wait to see more of it!

man if you sold this i would so buy one. seriously, there is nothing for a reasonable price at this size on the market, even if you sold it as a kit with instructions

Neat way of keeping the bed rigid, I appreciate that you took the time to look at ways to upscale the basic creality design. Be careful not to say you designed the printer from scratch, because you made it from scratch. This design has been around since before prusa started making his 100, 000 printers. On the other-hand, you totally designed that bed support style and there is no problem with you saying that you designed that, because you did.

My thoughts on this:

1) Congrats on the custom build! It looks really nice!


2) If you decide to build another printer, consider making one that moves the bed in the Z-axis. It will require less speed, making for lower vibration, and you can actually print precision parts *fast*. Right now, you are using a large nozzle size with, I suppose, a large layer hight? That will work, for large parts, but will leave *heavy* ringing and issues when it comes to the y-axis. The bed's mass vs the belts is both going to wear it out really quickly, but also impact the prints.


3) You *need* an auto leveling system for that printsize with that budget bed. Mirrors are nice, but as you noticed, don't take thermal stress very well. Any bed surface you build with that size is going to have some sort of warping, or at least develop it over time. I would recommend a genuine bltouch. It actually probes the bed with a little stick, and has incredibly high accuracy. You usually combine it with manual leveling. (you can add four macros, each for one corner, and it will move to that place, probe, and give you the result in the log. so you can screw each leveling screw to absolute perfection, and check it out).

Imagine the giant Lego we could print 😬

"I will bodge it!" Spoken like a true engineer. 😉

[flexmcpee]

Why all the bad comments? This is amazing work and engineering. Sure who needs a printer that big but who “needs” a printer at all if that’s the case. Again amazing work right there!!!!

[malthungaming]

My question is how much was the total final cost? Cause this is something I desperately need!

[MrNlce]

Great job there's a few things you need to do now
1. Name it
2. Print a 4 leaf clover to help counter the 7 years bad luck
3. Make and sell kits
Great video. Keep up the good work.

They need this guy on mars to assist with the 3D printed habitats!

[donutboy]

Nice build. The wire and ptfe tube management on the carriage is very inventive. I might have to borrow that design for myself. Thanks for the video.

[ld-dmaker]

you got a hermes and a supervolcano, time to print BIG and FAST! see how fast the big printer can go without quality loss, would be very interesting (maybe 80mm/s with those thick lines? not bad)

[SaitoGray]

I can't manage to level my old 220*270 printer and you build this. That's awesome.

[nickelpence]

The discount on the red filaments isn't ended yet, isn't it?😂

[grandbabiesransom]

Good job Ivan. I saw your other video when you began building your 3d printer and I was surprised. It works. Ivan you are talented. All I can say is WOW. Again good job Ivan.

[MakeOn]

Stunning. This is absolutely, ridiculously majestic!
Not that I have now space to keep it or a reason to build it, but I definitely would!

Awesome work, Ivan!

[billjames]

Glad to see another person using mirrors. Use mirrors on all four of my printers.

[calebleach]

I'm going to build this printer. Thanks for posting.

Looks like it's big enough to print exterior trim parts for cars like the molding on doors and windows that always gets broken or lost.
