Tesla's Flying Roadster: What's Actually 3D Printed (and What Isn't)
Tesla's new Roadster flipped off a ramp and jumped a Semi on compressed-air thrusters. Everyone is asking how much of it is 3D printed. Tesla hasn't said a single part is. Here's what's confirmed, where printing really shows up at Tesla and SpaceX, and the tank math Tesla left out.
By Dreaming3D · San Diego, CA
The short version
- It hopped, it didn't cruise. A driverless prototype made brief airborne jumps using cold-gas thrusters fed by stored air. Nothing burns.
- Zero parts confirmed as 3D printed. Tesla gave no manufacturing method for the thrusters, tanks, fans, chassis or seats.
- The printing story is mostly next door. SpaceX prints combustion engine parts; Tesla, per Reuters, prints sand molds for castings. Neither is confirmed on this car.
- Tesla gave mass and volume, not pressure. 250 kg of air in 600 liters implies roughly 437 bar (6,339 psi) at room temperature. Our arithmetic.
- No price, 2028 production. $50,000 and $250,000 are reservations, not prices.
What Tesla actually showed on Oct 15
Tesla revealed the second-generation Roadster on Thursday night at SpaceX's test site in McGregor, Texas, near Waco. Nine years after the 2017 concept, the car is a new wedge-shaped two-seater that Tesla says was developed with SpaceX engineers.
The first stunt: the car drove up a curling ramp, held itself upside down with a fan-driven suction system that Lars Moravy, Tesla's VP of vehicle engineering, said can pull up to 2 g, then left the ramp inverted and used thrusters to roll upright and land. The second: a launch over a lineup of Teslas including a Cybertruck and a Semi, with a mid-air flip that Tesla called the kickflip. A timed run hit 60 mph in 0.81 seconds, according to Not a Tesla App's recap.
Nobody was in the car. Musk told the crowd the prototype drove itself so they wouldn't kill anyone, and said success was not guaranteed.
Tesla is taking reservations for three versions:
| Trim | Tesla's label | Seats | 0–60 mph (Tesla claim) | Thrusters | Reservation |
|---|---|---|---|---|---|
| Performance | Road ready | 2 | Under 1.6 s | None (suction fans, active aero) | $50,000 |
| Thrust | Race ready | 2 | Under 0.9 s | Rear cold-gas thrusters | $250,000 |
| Rocket | Air ready | 1 | Under 0.59 s | 10 cold-gas thrusters around the car | Invite only |
Tesla quotes more than 300 miles of range and a top speed above 230 mph. Musk said production is planned for 2028 and gave no price. Tesla's own page notes the Rocket isn't available in all regions, and coverage of the event reports Tesla marks it as not approved for public roads.
What the headlines get wrong
- "Tesla built a flying car." It built a car that can leave the ground briefly. CNN noted there was no demonstration of long-range flight, and nothing suggests it can stay up the way an eVTOL or plane does.
- "Rocket engines on a car." These are cold-gas thrusters. Tesla says they vent compressed air through nozzles; there is no fuel and no combustion. The car is said to refill its own tanks.
- "A 3D printed flying car." No Tesla source names a printed part on the Roadster. That may change, but today it's a guess.
- "It costs $250,000." That's the Thrust reservation. No trim has a price.
So which parts are 3D printed?
We went through every subsystem Tesla described at the event and in its posts afterward. Here's the ledger:
| Subsystem | What Tesla said | 3D printed? | Our note |
|---|---|---|---|
| Thruster nozzles (up to 10) | cold-gas nozzles developed with SpaceX | Not disclosed | Process not disclosed. SpaceX's printed SuperDraco chamber burns propellant and has cooling channels built in; a cold-gas nozzle has nothing to cool. |
| Air tanks (two COPVs, 600 L) | carbon fiber overwrapped pressure vessels | Fiber-wound by design | COPVs are built by winding carbon fiber over a liner, a different process from 3D printing. |
| Suction fans and diffuser | fan system pulling up to 2 g | Not disclosed | Process not disclosed. |
| Chassis and castings | lightweight structure, no method given | Printed tooling elsewhere at Tesla | Tesla's reported printing is sand molds and cores for castings. Not confirmed for Roadster. |
| Seats molded into the chassis | one-piece seat design (patent) | Not disclosed | Process not disclosed. |
| Active wing actuators | Optimus actuator system | Not disclosed | Process not disclosed. |
| Battery and drive unit | 1 MW, half the mass of Plaid's | Not disclosed | Process not disclosed. |
That's an unsatisfying answer for a 3D printing shop to write, but it's the honest one. Below is what we can say with evidence.
The thrusters: SpaceX prints engines, but these aren't engines
SpaceX's best-known printed part is the SuperDraco combustion chamber on the Dragon capsule: Inconel, made by direct metal laser sintering, with cooling channels built into the wall. SpaceX said in 2014 that printing let it make the part at a fraction of the cost and time. We covered that story, and Tesla's different approach, in SpaceX Prints the Part. Tesla Prints the Mold.
The Roadster's thrusters are a different animal. A cold-gas nozzle has no flame, no hot wall and nothing to cool, so the main reason to print a SuperDraco chamber doesn't carry over. A nozzle like that could just as easily be machined from bar stock. Printing could still make sense for a manifold that splits one feed into several nozzles (the display Sawyer Merritt filmed showed one tank feeding a four-nozzle manifold), because printing lets you route internal passages in one piece. But that's a possibility, not a disclosure.
The tanks: carbon fiber, wound, not printed
Tesla says the air lives in two carbon fiber overwrapped pressure vessels, or COPVs, the same tank type SpaceX flies. A COPV is made by winding resin-soaked carbon fiber around a liner. That's composite manufacturing, not 3D printing, and Tesla hasn't said anything to suggest otherwise. TechCrunch pointed out that COPVs have been involved in several SpaceX failures, which is part of why the pressure question below matters.
The chassis: where Tesla really does use printing
Reuters reported in September 2023, citing five unnamed sources, that Tesla works with firms that 3D print industrial sand into test molds for its giant castings, and plans to use printed sand cores to cast hollow subframes. Tesla didn't respond to Reuters. In that model, the printed object is tooling that gets broken out and thrown away; the part on the car is cast aluminum.
CNBC reported the prototype is built to be as light as possible, and Tesla has shown seats molded into the chassis, but it hasn't said how the structure is made, whether it uses castings at all, or whether printed sand was involved. For a car Tesla expects to build in small numbers, there's no public reason to assume either way.
Prototypes vs. production
Show cars across the industry routinely carry printed trim, ducts and brackets because it's the fastest way to make one of something. It would be unusual if this prototype had none. But "unusual if it didn't" isn't the same as "Tesla confirmed it," and the production car in 2028 could be built very differently from the one that flipped in Texas.
The number Tesla left out: tank pressure
Moravy gave two numbers on stage: 600 liters of tank volume and about 250 kg of air. EVXL noted that Tesla gave no storage pressure. You can work it out.
Our arithmetic
- Density: 250 kg ÷ 0.600 m³ = 417 kg/m³.
- Ideal-gas pressure at 20 °C: about 351 bar. At these densities air is stiffer than the ideal-gas law assumes, so that undershoots.
- Real-gas pressure at 20 °C (CoolProp air properties): about 437 bar, or 6,339 psi.
- If "about 250 kg" means 240 to 260 kg: 409 to 467 bar.
- For comparison, the 10,000 psi (690 bar) figure attached to Musk's 2018 "SpaceX package" in reporting summarized on Wikipedia would put about 319 kg of air in 600 liters. The numbers Tesla gave this week don't match that.
Two caveats. Tank temperature changes the answer: hot tanks hold the same mass at higher pressure, and air cools hard as it vents. And "about 250 kilos" is a spoken round number. Treat this as an estimate, not a spec. What it does tell you is that these tanks run well above the 200 to 300 bar of a typical scuba fill.
That's also the clearest line between what Tesla and SpaceX do and what a 3D printer in a garage or a small shop should do. Parts that hold pressure are certified hardware. Nobody should pressurize an FDM or resin print, and we won't.
What a genuinely 3D printed car looks like
If you want a car where printing is the point, look a couple of hours up the 5. Los Angeles-based Czinger builds the 21C hypercar on Divergent's production system: laser-printed aluminum nodes joined with carbon tubes and extrusions, adhesive-bonded by robots. Kevin Czinger told 3D Printing Industry in 2022 that almost all of the frame structure and nearly the whole suspension, apart from items like the shocks, are printed. Divergent has also supplied a printed aluminum rear subframe for Aston Martin's DBR22 concept.
That's the contrast worth keeping in mind. Czinger and Divergent publish what they print because printing is the product. Tesla published thrust, suction, range and acceleration, and nothing about manufacturing. Until it does, "3D printed flying car" is a headline, not a fact.
Where we fit, here in San Diego
San Diego has a deep aerospace and defense bench, and plenty of people here want to hold a piece of this stuff in their hands. Here's what we can do from Carmel Valley, and what we can't:
- Educational models. A sectioned converging-diverging nozzle in resin is a great way to show why gas leaving a nozzle can go faster than sound. Generic geometry, your dimensions, no pressure.
- Display pieces of your own design. Stands, plaques, desk models and cases. We print your designs, not replicas of someone else's car.
- Shop tooling. Jigs, fixtures, soft jaws and drill guides: Tesla's "print the tool" idea at small scale.
- What we don't print: pressure vessels, thruster or flight hardware, metal parts, firearm components, or anything load-bearing or safety-critical.
FDM machine time is $7 an hour and resin is $9 an hour, and we also do 3D scanning and reverse engineering of existing parts. Start with the project request page or text us.

Is the Tesla Roadster really a flying car?
Not in the aircraft sense. On Oct 15, 2026 a driverless prototype made short airborne hops: it flipped off an inverted ramp and jumped a row of Tesla vehicles, using compressed-air thrusters to rotate and land. No sustained flight was shown. Only the invite-only, single-seat Rocket trim carries the full thruster set, and Tesla says that version is not approved for public road use.
Which parts of the Tesla Roadster are 3D printed?
None that Tesla has named. Tesla described the thrusters, the carbon fiber overwrapped air tanks, the suction fans, the battery and drive unit and the active wing, but gave no manufacturing method for any of them. Tesla's best-documented use of 3D printing is indirect: Reuters reported in 2023 that it uses printed sand molds and cores to develop large castings. Whether the Roadster uses any of that is not disclosed.
Does SpaceX 3D print the Roadster's thrusters?
Tesla hasn't said. SpaceX does print rocket hardware, most famously the Inconel combustion chamber of its SuperDraco engine. But the Roadster's thrusters are cold-gas jets: they vent stored air and burn nothing, so they don't need the cooling channels that made printing attractive for SuperDraco. They could be printed or machined; there's no public answer yet.
How much pressure is in the Roadster's air tanks?
Tesla hasn't published a pressure. It said the two tanks hold 600 liters and about 250 kg of air. Using real-gas air properties at 20 °C, that works out to roughly 437 bar, about 6,339 psi. That is our arithmetic, not a Tesla figure; 240 to 260 kg would put it between 409 and 467 bar.
How much does the Tesla Roadster cost and when does it ship?
Tesla has not announced a price. It is taking reservations of $50,000 for the Performance trim and $250,000 for Thrust; the Rocket is invite only. Elon Musk said production is planned for 2028. A reservation holds a place in line, not a price.
Is the flying Roadster street legal?
Tesla says the Rocket version is not approved for public roads, and Musk said on stage he wasn't sure it would be legal everywhere. The Performance trim is the one Tesla calls road ready. Thrust is described as race ready.
Can Dreaming3D print Roadster or thruster parts?
We print display models of your own design, educational nozzle cutaways, mounts, fixtures and other non-structural parts in San Diego. We don't print pressure vessels, thruster or flight hardware, or anything load-bearing or safety-critical, and we won't pressurize a printed part. If you're not sure where your idea falls, send it and we'll tell you.
What we'll update
We'll revise this post if Tesla names how any Roadster part is made, publishes a tank pressure, announces prices, or changes the 2028 date. Seen something we missed? Tell us on Instagram at @dreaming3dprinting.
