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.
“We”
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 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’d dare to say no different than any of those guys in charge
Exactly. Who has the one promoting it? It was you, Elon.
Credit for innovation: capitalism. Credit for failures: socialism.
Musk and the sycophants he surrounds himself with
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?
Bruh that delay was because of the PLANDEMIC!!111!!

Every time the stock dipped, often after intentionally driving the stock down before pumping it back up.
Gee… telling the engineers to getting precision to below 10 microns would cause production challenges.
Flashbacks to Steve Jobs and the NeXT Cube.
I have what are basically toy 3d printers capable of 1 micron precision…
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?
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.
Which printer is giving you 1 micron precision?
It depends on the model being printed.
1 micron is easy to achieve on the Z axis with almost any printer, using any 3d printing technology (FDM/SLP/SLA/etc).
In the X/Y axis, the vast majority of FDM printers are off the table for 1 micron - increasingly so as the Z height of the model increases, especially on bed-slingers like the Ender 3. The taller the model, the harder it is to maintain accuracy on X and Y.
In SLA/DLP printers, it’s all about the motor, controller, and whatever shields excess light/beam diameter.
To answer your question directly: I have no trouble getting highly reliable micron accuracy in a $99 Creality Halot. The key is to understand your model in relation to the pixel density of the screen. Some calibration prints tell you where the steps are, describing the relationship between input and output - which will most certainly be different from printer to printer at the consumer level. Once you have that data, some simple math tells you exactly how to design your object in a way that takes these natural constraints into consideration.
Yes - at any scale, even at the size of a car…or a battleship. When you accept the constraints of the hardware into the design of the object being produced, you can get micron repeatability out of just about anything.

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.
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 the fuck outta here with your dumb 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 ya dumb-dumb. 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 with your stupid ass arguments. 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.
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).
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)
Wasn’t he the one who made a bunch of ridiculous demands? This car seems like it was designed by Homer Simpson.
In my head it was Elon who sketched the truck and told everyone “make that exactly how I drew it”
No way this thing is soft and yielding like a nerf ball
Yah there’s even an episode where Homer designed a car. Didn’t go well.
“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.
*invents stupid and logicitally impossible truck.
*Production challenges
It didn’t go through, guise ah ah ah ah
What a massive dunce

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?
When I was a kid, I asked my dad why the cars on the road didn’t look like any of the prototype cars I saw in autoshows or car books.
Now Elon has given me the answer. Those cars are hard to make at scale. One is doable, but thousands is impossible.

They? Elon Musk owns Tesla. He gets to decide what they spend the money on.
As I understand it he is still answerable to board of directors. Isn’t he?
I seriously doubt any of them have any control over him. He controls their income with a single meme tweet.
I actually thought this was an elaborate joke. The “Cybertruck” looks like a piece of shit, and apparently is a piece of shit.
I cannot believe it, this coming from the man who knows more about production and manufacturing than anyone alive! For sure the Genius of Musk will find a solution to overcome this.
Like when he demanded 10um tolerance for the assembly of the cybershmuck nobody understood and they said it’s impossible. But he realised, he realised early on that the mail will leak and idiots will take it as an argument of quality and performance and be motivated to throw money at him. Conmen need money inflow to keep the scheme going.
/s or not …
The real story is that a million people have reserved this thing.
. Cybertruck.Haha that’s so–
Actually, never mind. I don’t care that much.
