Watching you put that printer on the concrete so aggressively physically hurt my soul 😭 but seriously, all of your videos are so funny and entertaining and you are an inspiration to me as a teenage girl who loves engineering

[@djjc9782]

must be nice to be given a printer by a company, so you can just dash it onto your floor. kinda douchey, but, hey, comedy i guess

[@sqiudy-catmedland1421]

​@@djjc9782to be fair, what she does with her 3d printer, whether its bought with her own money or given to her by a company, is her own business

[@EmilyTheEngineer]

lol you mean an old printer I bought a long time ago that no longer works and I just use for parts now? be jumping to conclusions so quick lmaoooo

[@sqiudy-catmedland1421]

@@EmilyTheEngineer oh my god 😅 I assumed it was one you dont use anymore but I still couldn't stop myself from internally cringing at how hard you put it down lol

[@greenman360]

It looks like an Ender so nothing of value would have been lost.

please also to encourage Emily to make 3Dp with Long Y-axis - to cure all current problems with 'tall' printing (see my comment below if you can find) .. and when you make more metal 3Dp rockets, u secretly love Tomato? :D

[@therottenpotato9660]

is it the way of the future or is it the future of the future

[@TTM1895]

Something completely helpful, yet useless because it's dangerous as hell. I approve of this video 100%. Well done Emily.

[@daliasprints9798]

Once you jack up a car, you put jack stands or solid wood blocks or something else under it before going under, so I don't see how this is unsafe. Oh, there was a jack stand too.. 😂

[@MOE13576]

​@@daliasprints9798you forgot the part where it's going up.....

[@T3CKN0G33K]

it would be cool to see how fast someone can change a tire before it breaks.

[@Enjoymentboy]

This is one of the things I love about 3D printing: Using $200 of filament and 20+ hours of printing to make something that I can buy for $50 and a 10 minute trip to the store.

[@RichChh]

🤕

[@BuiltOverBot]

I am sure I am not the only person wondering if a 3d printed jackstand is as safe as a harbor freight jack stand.....

[@AaronALAI]

😅😂

[@nathanieljames7462]

safe is a strong word

[@EmilyTheEngineer]

don’t tempt me. now I wanna see which fails first hahaha

[@BuiltOverBot]

@@EmilyTheEngineer they recalled the really bad ones they may be hard to find

[@JH-zo5gk]

Depends on the brand. The Daytons are solid enough. Project farm did a jackstand comparison.

[@Maker_of_Things]

Given the terrible mechanical efficiency of the jack when it at the start of its lift, I was cringing all the way, and very impressed at the lack of shrapnal. Now I am wondering how a 3D printed conventional screw jack (vertical thread) would cope. Brilliant video!

[@BramCohen]

The specs for PLA vs PC show some values better for PLA and some worse, and the ones which are worse aren't all that much worse. PLA is an all-around great material, with its weak points being that it melts at a relatively low temperature and when it fails it really fails. If you want/need something tough the materials to use are nylon if you want it hard or TPU if you want it soft. A good trick for making strong 3d printed parts is to embed metal bars (which you can get cheap) inside a print in strategic places.

[@the_hottest_pizza_rolls1300]

Emilys green screen is impeccible. 👌

[@CarsSimplified]

Impressive stuff! I was expecting at least one attempt to shatter into confetti.

[@3DPrintingNerd]

DUDE. Let's you and I collab on printing that in some CF PEEK. YES.

[@kentslocum]

Ahh yes, I keep a 3D printer in the back of my car for just such an emergency. It only takes a few dozen hours to print a jack so I can change my tire.

[@UltimateP]

Yeah same, but if it were me, I'd just print a new car.

[@kentslocum]

@@UltimateP That's a very big-brain move. No wonder I didn't think of it!

[@ydoucare55]

Cool project! You can optimize the orientation of the screw when printing by printing it on it's side on the build plate rather than standing up (you can add flatness to either side of the screw). By standing it up like that, the load on the jack is going to try to pull the layers apart, which contributed to the first failure. The adhesion between the layers will never be as strong as a continuous piece of filament, unless maybe you anneal the parts.

[@ahow8017]

A little grease on the screw would have helped also. I bet the factory jack had grease.

[@sharfold]

Fantastic work! A longer cranking handle will make it easier to lift the car higher, especially as more weight is added. For a higher lift without wooden blocks, longer lengths on the middle blocks will do the trick, love the fact you added gears on both ends, fantastic fix!

[@arthurwippel]

I really loved the way you show your content Emily. Keep it up, cause you're doing great! Also great topics on the channel! 😁

[@chadjmoore]

The best parts of the video, asside from the super cool design and eng; it is the genuine excitement with success. keep going!!

[@Bevel_and_Bark]

It’s been a hot minute since I’ve seen a new vid. So happy more are coming in.❤

[@Nixqy]

Not sure how i havent come across your channel before, but this was great! looking forward to more

[@sebastian_olthuis]

Just a little tip infill quite fast gives diminishing Returns. Try more walls/perimeters and top and bottom layer. Also add a 0.4 mm tube inside the model at Connection Point so there are solid walls printed on the inside of that part to connect them so they don't snap so easily. If you wanna make an unreasonable strong part 45 infill 6 walls and top and bottom layers with alternating wall direction with cubic infill. Most importantly get good layer adhesion. Also increase line thickness/with to 0.6 (don't need a 0.6 nozzle if you stay under 0.24 layer height). Also helps to burn though having to Mutch filament and to little microplastics everywhere.

[@1SmokedTurkey1]

Yeah no both are important if you want the strongest part possible. Why stop at 45? Diminishing returns sure but every bit helps here. I made some very questionable and borderline illegal explosive stuff with my 3D printer, 100% infill always.

[@themacbookgamer]

Ive heard you on the Lateral podcast a couple times, but this is my first time actually watching one fo your videos. I've gotta say I'm hooked XD that was amazing

[@zebarzebra]

Great video - cool idea and fun too watch!

[@nathanieljames7462]

Destructive test analysis is the way to go!

[@ChrisLocke1969]

Go for more walls, less infill. Like 6 or 7 walls, 50% infill.

[@ghostshadow1]

That was pretty impressive honestly haha! I printed an oil filter cap wrench last summer when I was in a pinch because the metal one I had didn't fit the car I was working on and surprisingly it held up quite well. I wouldn't ever try to jack a vehicle up though lmao!

[@RJ-wx3fh]

i agree this is firmly filed as 'i'm surprised it can technically arguably hold a car' rather than a properly functional solution, but i do wonder how well a large 3d printed puck or block would fare as a non adjustable jack stand.

[@foxtopuscreations6046]

Emily slid that piece of paper under the tire like she was levelling it. Gotta level all 4 corners.

[@ZSchrink]

WHOA, I'm impressed!

[@narancs5]

I have a car which weighs half as much as yours. This will allow me to save even more weight by throwing out the "big&heavy" factory jack replacing it with a plastic one. :D Honestly knowing how much time it takes to print these parts is crazy and you just go with the flow with the video which is cool.

[@dl200010]

Unlike the lawnmower's tire, the car's tire actually can swing up and down, so that explains the need for the extra wood.

[@martinjohnston1907]

I had the actual metal jack that came with my car fail spectacularly one day. Got it jacked up the angle of the car shifted as it was raised the jack twisted and the nut popped off the screw and dropped it to the ground instantly. I had never seen a screw jack fail like that. Never get under a car supported only by any jack.

[@KhatabRobotics06]

Emily "should I have a shield in front of me?" me "you only though of that now"

[@ScytheNoire]

Wait, the first models were made out of PLA? PLA! That's impressive for PLA. I don't use PLA for anything that needs to be functional, I always go to PETG or ASA.

[@Camberlam]

What glue do you use for pla?

[@robertheinrich2994]

just as an idea: the straight lines etc are mostly from older manufacturing processes that had an easy time with straight objects. you could process your car jack with a strength optimization algorithm. it would look more organic light (think about bird bones which have to be rigid and extremely light or trees, which have to be optimally balanced, as they cannot afford to be too heavy). these forms are hard to manufacture with traditional methods, but as you know, 3D printing does not have some of the limitation that other methods have. and think about the infill type, depending on the type, they are sometimes just load bearing into one direction. gyroid should be the way to go.

[@tonykyle2655]

we were watching the video because you put it out there. :D

[@richiebricker]

Very cool!!!

[@JohnDlugosz]

If you were on an island and relying on printing rather than a conventional shop in order to produced needed tools, you would design them based on the material properties. The plastic jack would not *look like* the conventional metal jack. It would have different proportions and appear oversized in general. E.g. the screw might be much much larger and have a fine pitch, and there might be other design features to take the load off the screw threads, like a ratchet.

[@Spencer1609751]

That jack stand is just like the Harbor Freight tools jack stands!

[@diomar13ful]

Is there any way that I can get this model to print it myself ?

[@Yavorh55]

[@knownchild]

[@johnrehwinkel7241]

With all the creaking, I was guessing there wasn't grease, but then you said "grease is gross", so I guess that's just the noisy nature of plastic under pressure. I'm glad you did this so I don't have to!

[@Edaurd]

I know for a fact my printer will NOT be able to print this in such a way that it would be able to hold its own weight lol

[@RamDragon32]

Yeah, a lot of your strenth issues could have been -solved- improved with changing the orientation of the print. But it is still really cool to see how strong some redily available printing materials can be. Then again, what do I know. It took me three tries to spell check "the" in the first sentance.

[@jorgecalero6325]

This is so utterly preposterous,yet it looks fun

[@jblcontrol28crossover76]

Some suggestions for your consideration: Shape the head of the lead screw similar to that of a flange nut. Place a thrust needle roller bearing between the flanged face of the lead screw head and the non-threaded block. Make sure the type of lubricant used does not effect the integrity of the plastic.

[@0bm31770]

That was impressive. It helped me decide to 3D print a mount for a luggage box for my motorcycle. The loads will be light compared to yours.

[@casfren]

I think the most impressive part is that you were able to put so much torque on that wrench without stripping out the wrench or rounding off the nut.
