I think I found the 3d printer version of Michael Reeves, and I'm totally here for it!

As someone with one working printer and two out of commission, this was equally frightening and entertaining to watch.

I would surmise that if the mineral oil was heated close, but not exactly at, the temperature the filament, that the printer might have kept printing. It was pretty cool that the printer head wasn't corrupting the filament by adding oil between layers.

it would be so cool to disable the thermal run away from Marlin just to finish the print submerged in oil (of course add disclaimers so people don’t try that) 👀

As a man in my forties living in my own basement, I approved of this experiment. It answers questions that I never new I had. Thank you, ETE.

The printer coming out of this alive and usable is amazing

You should insulate the heat block with several layers of high temperature silicone. I think you may be able to get it to hold temperature then. I’m amazed that mineral oil didn’t prevent the layers from bonding.

Next challenge: printing with a resin printer upside down 😜 But seriously, cool vid! just goes to show how robust these printers actually are and you don't always need to baby them.

the question isn't what to do with the 3D printer next, the question is what to do with all that mineral oil.

I'm glad we could help you "do stupid things with a printer!" But actually I'm trying to figure out where to put my printer and attached upside down to the ceiling makes more sense than my other ideas...

I’ll have to think about it more but maybe an advantage to printing upside down is reducing support material in certain use cases. Changing the gravity vector strategically mid-print could be helpful for full round stuff or objects with deep overhangs? Fun video!

Ahhh. I remember when i started 3d printing, and my family treated the printer like the most delicate thing on earth. Aaaannd you printing with it ziptied to the ceiling.

I was laughing in delight the entire video. Love it!!

hahaha I filmed the same video a while back 😂 but I never got around to editing and posting it! I printed in dry ice, upside down, outside, and on battery power. Survived no problem! Ender 3 is a tank! (most of the time, not always! 😉)

Now the real question is.... Can it print in space?

First off, let me say I appreciate the old-school KZfaq vibe you give off. This video feels like the good old days before everything became formulaic. Secondly... oil should absolutely inhibit bed adhesion. We're told constantly to wipe the beds down with alcohol to clean the oils off. Since you've already put this little trooper through so much, I'd really like to see you test other bed contaminants. Because mineral oil is petroleum based, does it interact with the molten plastic in a way that organic oils don't? Will vegetable oil, natural/synthetic motor oil, WD-40, 3-in-1 oil or whatevs behave the same way? Inquiring minds want to know!

This is the right amount of 3D printing shenanigans i needed today, Thank you

I think the best way to print submerged is to turn off all the fans because it does not need cooling. and put the printer after the mineral oil once submerged you let it heat up for half an hour or so to heat the oil and if it doesn't work mon water heaters in the farthest corner and leave it for a bit so the heat won't go away

5:45 Emily: "Hello, I got a child here...he only has a slight fever of 200 degrees celsius..." what a child keep it up

Throw a higher wattage heater on the hot end. Use a silicone sock to help insulate the hot end. Make sure to do PID tuning of the heater control while its submerged in oil. Heat the oil up using the print bed or an external heater to reduce the delta T between the hotend and the oil.

Thank you for doing all this, I have wanted to try some of these for a few years.

this is soo janky. i love it. also, that's the 3d printer foods speaking when the printer got zip tied upside down 😂 imagine the views of the printer fell lol

I spent so long failing to get my Ender to successfully print ANYTHING that this video almost made me cry LMAO. great content

everyone else: todays sponsor is raid shadow legends emily: my sponsor is CHANGING THE WORLD!!!!

My ender3 v2 has the exact same layer shift. Not sure what's causing it yet.

Very impressive... That's all. Very impressive. I can't think of anything to up the ante past printing underwater.

I love this! I'm gonna have to try this with my printers now!

MORE!!!I wonder what is the Maximum overhang you can achieve with the printer Upside Down or Sideways? especial if you plan the pathing to use gravity to it's advantage (like top to bottom for sideways mounting)

I can't believe that is still worked so well. Great video!

And here i am, still having trouble leveling my bed when its on the table

This channel is legit, keep up the content!

I love this channel!!!! You are doing all the stupid "what if stuff" with your printer so we don't have too!!!! Thankyou ma'am!

Even if it works, I can't put into words just how much the idea of this terrifies me, I love my printers too much to try it

you’re genuinely hilarious!

That looks like a Hulk Buster sized workshop Emily! I love your videos thanks!

I appreciate you, great sense of humor. I'm just here doing the stuff in supposed to.

What if you use some sous vide machines to warm the oil up to like 130-150ish or something? Hot enough so the hot end can stay hot but low enough the plastic can cool?

Finally a new video ive been looking foward to a new video

It's good to see your videos on here again

Didn't think I'd laugh this much at a 3D printer video. Bravo! You are hilarious.

Does this affect the need for supports? Will overhangs turn out better if the printer is upside down?

I wonder if the oil can reduce the amount of support structure needed. To print without nozzle temperature issues, either keep the oil level at nozzle height, or heat the oil (might also reduce warping?).

Would it still work with heating up the oil? Note, only with great ventilation and knowledge of what happens to the oil at high temperatures

I’ve wondered about using a fluid as a support for overhangs.

Oh man instead of zip ties I thought you were going to say duct tape.

what if you had the filament running out of the oil? one trick that people do is they use some oil to greese the PTFE tubing. so maybe that could help...idk.

"WRONG! It still works!" haha. I would love to see you try again with an "enclosure heater" to prewarm the oil so the printer isn't struggling trying to heat the entire vat. You can move the power supply and control boards outside of the vat, so they don't have an issue with the heated oil. Next, you can modify the marlin firmware as needed to adjust for thermal runaway, and PID tune the hotend so that it can properly heat up and cool down in the oil. I would still use the heated bed, but an added oil heater so marlin doesn't freak out trying to heat the bed forever. I know this was about "how far can I push the printer", but I think it became "can I print under mineral oil?" pretty fast. Sometimes those mineral oil PCs have some components which are external, especially additional radiators and fans, so I don't really see this as cheating at all.

So a core xy printer with the hot end above the oil and the bed lowering into the oil it would cool prints well ?

Is it possible to print cheese? Print a moon out of cheese perhaps so we can finally answer the age-old question of "Is the moon made out of cheese?"

Not sure if I'm remembering correctly but I think when 3D printing first started (as a hobbyist/desktop style) that the people used to oil the filament to make it go on through the extruder/hotend...

I won't lie....for just a moment, I envisioned my walls/ceiling covered in printers....awesome test!

can we agree that the Ender took it like a champ? like I did not expect to handle everything let alone print perfectly

Absolutely impressive!

if you print upside down, do supports still work? do you not need supports?

The will my dad ever love me got me 🤣

You should try heating the oil with a sous vide cooker. Or aquarium heater. You may have to tune the pid but I bet you could do it

0:55 watching this and laughing my ass off ... while I was starting up litterally my ... Ender 3 xD

what if you put a heating element into the oil to get it up to temperature?

Wow! I'm only 4 minutes in but definitely already subscribed and loving the content and energy!

I cant believe it kept printing thru all that. And hear I am babying mine. Lol

This is so awesome 😂

Wow. A hardcore printer! You should try putting it inside a wheel and then spinning it as it prints. Would look so funny.

Heating the oil may help! Have you considered trying deionized water? I’d like to see you try that instead of the mineral oil. Sharing this with ERRF people tomorrow, theres a dude there with a printer thats bed and extruder are upside down! Whole printer fits in a filament box too!!

Have you tried this with a high speed printer? I know Voron wants their printers to be mounted securely for high speed maneuvering. Would one being free to wiggle interfere with it's print quality??

First time here, this video was awesome 👍!!

This was a great torture test to watch and show some of the resilience of these things, but I think as an engineer you missed a considerably important test. I've heard of people wanting to integrate these things into vehicles for mobile printing solutions. The hanging test touched on some of the lateral and shock force testing that would be involved in this, but vibration would be the real test. You should totally do another one of these videos where you set the printer up on a vibrating platform and see if it will print. Then you can increase/decrease the vibration amplitude and frequency until it fails. Same with some sort of shock testing system to see at what impact level it stops working (impact being deferred shock from the printing platform not necessarily direct impacts to the printer itself). Someone in the comments mentioned seeing if it could print in space... setting up a vacuum chamber to put it in and test might be pretty cool (though complicated due to the forces and seam sealing involved). I'm sure the resulting issue though may end up being thermal runaway since you'd basically eliminate any kind of convective cooling.

at what G is the prints sustain form during printing in a centrifuge

I want to know if you can get a decent print in the back of a moving car

Coming up with some new ideas for you. Love it

I’m about to start a research paper for my comp class on 3D printing upside down

This is a great ad for the unstoppable and unmatched reliability of the Ender 3

An overhang test would be interesting. See how far you can gooooooooo

Now im wondering if one could use one of those sous vide cooking gizmos to heat the oil up, or would that just slowly deep fry the printer.

Emily was laying on the floor of the empty workspace, staring at the ceiling, and went "heh heh".

Unintentional Ender 3 ad! That sucker is resilient

what if there was a fiish tank heater in the mineral oil to warm it up you think it would keep going

I was just thinking about a spider printer today where you could use a hot end and have little fingers to move the filament like spider does.

You’re as ridiculous as I am! Love it!! 😂

I wonder how an upside down printer does with overhangs? Would love to see a calibration test with them

She's so funny. I love it.

I feel like this would be a fantastic commercial for ender 3 printers and how durable they can be😂

Loved it, but yea will NOT be doing the Mineral oil at the very least at all with my Prusa Mini (I only got the memo to AVOID a Ender, cheap 3D printer). lol

Beginning to think the layer shift is just a artifact in the Benchy model when it's sliced. Every print I have ever see seen, either my own or other people's, has that band right below the railing.

Ooh, mount the entire machine so it's supported only by the bed. Y-Axis should make the whole thing go back and forth.

Every benchy ive ever printed has that line in it in the exact same spot. Must be somthing in the file thats not noticeable in the slicer

Yep. Space seems to be next. What about printing in a vacuum? Then, what about a sound chamber that plays tones to match the resonance of the machine?

CPSdrone did a video about printing in a swimming pool and this reminds me of it

omfg plzz turn it into an rc car, i want it to drive around and print a lil car at the same time

This is, to quote you, the nail in the coffin. I wanted a printer, but now im gonna buy one

i can't imagine a better ender3 ad lol

“It’s my ceiling printer” 😎

Great stuff!

take 6 printers, mount them +-90 degrees off from their neighbors on the faces of a cube, and have them run the exact same g-code(in sync) while suspended from your ceiling. the 'print-die' bonus points for printing large d6.

My Ender 3 v2 lives on a bar stool in my garage.

me: *treats my 3D printer like a child, a god, made from gold and tears* this gal:

you could maybe put in a heating element to heat the oil

could you try printing in a vacuum? would probably be hard due to electronics (capacitors especially) not being super fan of the vacuum but is would be fun to test if you could.

Sidenote it looks like the oil bath cleaned up that layer shift on the last benchy.....Interestingly i've been fighting a z wobble on my cr10 and now I have an idea.

0:42 Lmao, even just saying Like this video in any context causes the dumb button glow feature. XD

Dumb idea list: - how fast can it print (not printer speed, strap it to the roof of a car and go for a speed run) - print a single wall square(or more walls if it leaks) around the edge of the bed and fill that with oil - Cover the bed in mini benchies and see if it'll push them out of the way (don't detach them) - something to do with chickens - print in a centrifuge
