Elon Musk says ‘we dug our own grave’ with the Cybertruck as he warns Tesla faces enormous production challenges::Tesla CEO Elon Musk said Wednesday that the Cybertruck’s unique design means the company faces immense challenges in scaling production.
The real story is that a million people have reserved this thing.
Given that I had dumbass coworkers at work who gleefully dropped $500 to “reserve” one of each trim, despite not even being able to even afford the cheapest trim (which will never even come close to existing with the listed price+specs), I’m not betting that it’s probably 1/4 of that, and about 1/4 of those will ever actually translate to purchases.
Gee… telling the engineers to getting precision to below 10 microns would cause production challenges.
What an idiot
I’ve been doing PCB-board design recently. Here’s the manufactuering specs: https://www.digikey.com/en/resources/dkred
So that’s 0.13mm tolerances to my printed-circuit board. Or 130 microns.
Current leading theory is that Elon Musk is such an ignorant dumbass that he doesn’t know the difference between mils and microns, despite running a car company / manufacturing firm. Give that a thought. Even then, 10-mils tolerance is near this PCB design, an object that’s only a few inches in size. Cars are much larger and normally should be built to much wider tolerances than a fucking PCB board.
I recently listened to a podcast about musk which was more on the anti side. The podcast had some parts about spacex and musks own work ethics, which told more of a story that he actually has some insights and knowledge and was a insane workoholic. Which shifted my perception of him. He isn’t dumb, he is a really good conman.
If he said <10 mils, I’d might have bought the explanation that Elon actually meant millimetres. Micron is a very specific metric-based unit which to Elon might have been trying to use like a buzzword.
The moral of the story is don’t say stupid engineering stuff if you don’t want engineers to laugh at you.
Ten mils is .010" or .25mm if I’m not crazy.
It’s a very standard tolerance for aircraft parts.
Yeah and that wouldn’t be too bad either… still expensive but not completely unrealistic for ALL parts of a car.
Kinda unreasonable for the number of cast parts most cars use, but for machined surfaces it shouldn’t be too bad.
And 10 microns at what temperature? Because on something the size of a car, made of mixed materials, thermal expansion of less than a degree is going to blow that figure.
They couldn’t apply paint to a tolerance of 10microns.
It’s almost like Elon Musk is a complete fucking moron and not an Engineer. The wanker has never actually designed a thing in his life. He just tells other people to design something, or buys an existing company, then struts around like he thinks he’s the smartest thing around.
He was fired for being incompetent. Only got rich because rich daddy and because he got lucky with stocks
I have what are basically toy 3d printers capable of 1 micron precision…
The problem isn’t that it can’t be done. The problem is that it is unnecessary and very expensive.
This is definitely true in terms of industrial production. (super cheap for “makers” - taking the hardware constraints into consideration with the design, of course).
Bullshit.
The thermal coefficient of expansion of say… Aluminum is 23.
That means that when a 1 meter piece of Aluminum rises from 20C to 21C, just one degree Celsius, it grows by 23 microns.
Your 3D printer is not a temperature controlled precision instrument. Your tolerances are no where close to 10 microns let alone 1 micron.
There are micron-level precise instruments in the engineering world. They all come with temperature characteristics because thermal expansion is a bitch. 3D printers that literally heat up hundred degrees and cools down regularly literally can’t be this precise, the heat alone wrecks your precision.
Bullshit.
You’re changing the premise of the question.
Pick a temperature - design your model to be whatever you need it to be at that target temperature - just like every other engineer with 26 years of experience, such as myself.
(by the way, my UV resin printer is quite temperature stable.)
Your resin printer does not have the resolution of 1/15th the size of a damn white blood cell. Your blood is 15 microns per cell or so. Red blood cells are smaller at around 7 microns.
You, and Elon, have confused your units quite significantly. I’ve given you the opportunity to see your error by reminding you the difference between thou, mils, mm, and microns. But apparently you haven’t gotten the hint yet.
My university created micrometer-sized balls, gears, and other such devices. They’re called MEMS and are really cool. They’re not made with 3d printers but instead lithography (same technology as computer chips, because they’re so small its easier to make through lithography). You’ve confused your units and its clear based off of how you’ve been talking. Take a step back, and double-check the difference from thou, mil, mm, and microns.
Sigh.
Please stop being confused about the capabilities of modern SLA/DLP processes.
What is the diameter of A PHOTON? And don’t forget to answer ignorantly, in a condescending i-know-more-than-my-betters tone. No, seriously - look it up. You clearly don’t know.
How many blood cells wide is light? By all means - tell me what the particulate size of photocuring resin might be? Could it be…2 microns maximum even for the largest ceramic-infused resin slurry - with sub-micron particulate sizes easily available even from Amazon? Yes - far, far smaller than blood cells. This is why you can’t let this shit get on your skin. It will literally traverse the blood-brain barrier. The fumes can get particles of this size into your bloodstream.
Well, what on earth can I do to get 1 micron accuracy from zero-width photons and 2-micron UV cured particles? Perhaps - design my model to be LITERALLY ANY SIZE that happens to be divisible by 2 on X, Y, and Z axes, then center it on the build plate?
Can you please get with the program, here? I’ve likely been doing this work longer than you’ve been alive. I’m not even supporting Elon’s demand, which is almost certainly unnecessary for this application.

Thanks for giving me more absurd examples. Your UV light is a 400nm wavelength or so. Or roughly 1/3rd a micron. The fucking wavelength of your curing light.
Now get outta here with your attempts at pretending that your $200 UV printer has the level of accuracy of three fucking wavelengths of the light it’s using.
The size of the color red? That’s 700nm wavelength, or 0.7 microns. Your resolution that you’re printing here is no where close to the size of red-light photons.
zero-width photons
Oh, so you don’t know how light works either. Good grief man… light has a size and you’re running up against the size limitation of the light itself. Especially because I know for a fact that these UV Printers are NOT using lasers, so you have no way to actually line up all the photons to hit the same location since their wavelengths are all unaligned.
In any case, car parts are not made at scales comparable to the wavelength of infrared light (ie: the “size” of a infrared-light photon).
Shocking narcissism, yet again.
You clearly have no intent to learn from your mistakes and pollute your entire argument with ad hominem and every other logical fallacy in the book - all wrapped up with a bow of dismissal of the original premise.
Oh, and by the way, light is both a particle and a wave. “light has a size” - indeed, the wave of light we aren’t talking about has a size - called wavelength. Don’t be afraid to use the most accurate terminology for your irrelevant responses! The wavelength has zero influence on the dimensions of the final product, as any wavelength more than a couple nm out of spec won’t cure the resin at all, and there will be no object to measure. I think you know that and are just trying to win an argument by talking over the heads of the average readers on here - which doesn’t help your case.
It’s extremely likely you legitimately have a personality disorder, and are capable of much more if you clean up your act.
Can you share a link? I’d love to buy me some of these.

Don’t forget - it’s not as simple as just buying the printer. You need the right resin, several iterations of test models, and the right modifications of the model to work within the constraints of the printer and material.
With the right tuning, you will be able to create parts which measure within 1 micron tolerance reliably. (don’t forget to use an indicator and good reference blocks - you aren’t going to measure microns with a caliper or micrometer)
Cool. Build 10 pieces and fit them together with sub 10 micron precision.
Ok, and once that’s done with the high level of repeatability and quality I’ve done it a thousand times, then what?
Which printer is giving you 1 micron precision?
Scale that up to a 4 ton production-ready consumer vehicle without introducing defects, I imagine
The heaviest Tesla is around 2.5 tons…but that’s beside the point.
The scale doesn’t matter. In fact, taking a desktop process and industrializing it makes it more accurate and repeatable - especially in a large-item manufacturing setting.
The best argument against the 1 micron requirement is that it’s unnecessary from a practical standpoint. I completely agree with that, for sure.

Seems like a reasonable next step!
Then take them to a different environment and measure them and then put a Lil water on them and measure them. Then get a mechanic to fix them and then shove it up your butt because any real engineer designing a car would tell you that kinda precision is just fucking stupid at production level for a car
I’ve already said a dozen times: no shit Sherlock, this is absolutely unnecessary for this application.
It’s also completely irrelevant to change up the environmental parameters when that is not a constraint set at the outset of this conversation.
I swear to God, it’s like there’s an entire subspecies of moron non-engineers who exist for the sole purpose of arguing where no argument exists.
A car doesn’t go through environmental changes? Because we are talking about engineering a car. You are talking about your 3d printed dildo of musks cock or something that you got into microns or some shit. It’s almost like there’s a entire subspecies of moron non-engineers who exist for the sole purpose of arguing about why musks cock is microns… you asked what to do next
Are you still arguing with a ghost? Nobody said a car doesn’t go through environmental changes… It just has nothing to do with this discussion.
“At this point I think I know more about manufacturing than anyone currently alive on Earth.”
Flashbacks to Steve Jobs and the NeXT Cube.
Lmao “if Lego and soda cans can do this, so can we.” At least he found materials similar to his existing vehicle build quality
Hey, don’t disrespect Lego like that
Serously folks have snapped steel rods using them.
“We”
Must be the royal we.
Exactly. Who has the one promoting it? It was you, Elon.
He’s very likely the one who pushed the engineers to try to make it work in the first place. They probably tried to warn him of the challenges it was going to face at every step, and he just used the power of arrogance, bullying, & positive-thinking to ignore it and just go full steam ahead with it. He would’ve just fired anybody that directly challenged him on it and told him what an idiot he is.
Not only they warned him. Reports are Tesla design department out of their own initiative and knowing how bad the proposed cyber truck was developed and alternate “sane” Tesla electric pickup truck proposal. When they tried to suggest it to Elon he reportedly didn’t want to here none about it and got mad.
He told the design boss just to make the existing design work. As we can see that didn’t end up going well.
Credit for innovation: capitalism. Credit for failures: socialism.
When things go right, it’s “I”. When things go wrong, it’s “We”. These are Musk’s situationally preferred pronouns.
No different than Trump
I’d dare to say no different than any of those guys in charge
Same narcissistic behavior. These are the narc pronouns
I mean, with Trump it’s more like ‘They’.
Yeah, Trump won’t accept any blame for anything, even when it’s obvious to anyone with a functioning nervous system.
I mean it’s capitalism in general usually. When the company is profiting, it’s due to the CEO. When the company is failing, it’s the fault of the company as a whole
When it fails it’s because of the economy, please bail us out.
Pretty standard for a rich boi
Musk and the sycophants he surrounds himself with
I actually thought this was an elaborate joke. The “Cybertruck” looks like a piece of shit, and apparently is a piece of shit.
Elon has a habit of doing this
“When you’ve got a product with a lot of new technology or any brand new vehicle program, especially one that is as different and advanced as the Cybertruck, you will have problems proportionate to how many new things you’re trying to solve at scale,” he added.
does it have new technology? i thought it was just like, shockingly ugly?
It took a lot of work to make windows that shatter so easily.
First you have to mass produce a lot of cannon balls, hire people and train them to throw the cannon ball perfectly so the broken window looks perfect.
It didn’t go through, guise ah ah ah ah
What a massive dunce
I remember watching this live, happy that my wife chose not to join me once they rolled it out, and ESPECIALLY after the window demo. Ugh. Cringiest night of my life.

Of all the cringiest things to ever happen on the internet this is one video I just can’t ever rewatch.
Just the most cringe in one video.
Who could have known that traditional manufacturers who have been building cars for decades have reasons to do it the way they did?
Surely not the man who reinvented the subway (but shitty) reinvented content moderation (but shitty) and reinvented the car (but shitty).
How come “normal” Teslas with traditional coachwork are selling, well not great, but good and every time Musk thinks he’s the genius who’ll singlehandedly completely reinvent a very competitive product he just creates a worse version?
There is exactly one reason I cancelled my tesla you stupid Muskrat.
You’d think the guy claiming to “know more about manufacturing than anyone else on Earth” would have anticipated such issues at the start of the design process.
Wait, that’s a real thing? I thought it was just a marketing stunt!
Tesla semi is a failure videos existed 2 years ago. Funny it took elon this long to admit it.

. Cybertruck.That’s weird, I could have sworn he said that they nearly had all the issues sorted out and that it was coming next month… Trying to remember when he said that… 2021?
Every time the stock dipped, often after intentionally driving the stock down before pumping it back up.
Bruh that delay was because of the PLANDEMIC!!111!!
/s
Need a shovel?
Weird, Ford and Rivian both seem to be able to make an EV pickup truck.
And GM, the epitome of “slow and bloated legacy dinosaur”, who in the time since Tesla announced the cYbErTrUcK, managed to design AND RELEASE a truck before Tesla even had prototypes. At this rate, I think they’ll technically have 3 different trucks out before a single cYbErTrUcK is sold.
The automotive giants always could have outpaced Tesla, they just didn’t want to because until it was viable with enough consumer interest (and competition), it was cheaper to only produce fossil fuel vehicles (and lobby against electric vehicles at every turn)
