Prusa is the secure option
95% of desktop 3D printers sold are made by Chinese companies. Prusa is the remaining 5%. Does origin matter? Yes.
“There is a real risk that data on prints, design models, or production processes could be transmitted to servers beyond the user’s control, including to the territory of the PRC.”
CORE One+ is TAA compliant, which is required for US government and federal contractor purchases.

6 reasons to bring 3D printing in-house:
Stop waiting weeks for outsourced parts
Print them overnight. You send a file in the evening, pick up the part in the morning. No quoting, no back-and-forth, no shipping delays.
Test 10 design iterations for the price of one prototype
A kilogram of highly consistent Prusa filament costs $30. That's dozens of test prints. You can afford to get it wrong five times and still come out ahead.
Make jigs and fixtures in-house in days, not weeks
Your team knows what they need. Skip the procurement cycle — design it, print it, use it on the shop floor the same week.
Print replacement parts that are no longer available
Machines outlive their spare parts supply. Instead of hunting for a discontinued bracket or waiting on a custom machining quote, just print it.
No minimum order quantities
Need 12 pieces? Print 12 pieces. You don't need to order 500 to get a reasonable unit price. Production starts at one.
Move faster than companies ten times your size
Big companies wait on procurement, approvals, and vendor lead times. You can have a part in your hand tomorrow. That matters.
Customer StoryOver 100 3D-printed parts in every aircraft
Shark.Aero engineers the fastest ultralight aircraft in the world. Not models - real planes that carry people. One of their Sharks was flown solo around the world by the youngest woman to ever do it. The whole aircraft weighs just 350 kg and cruises faster than most ultralights in its class.
Parts that actually fly
Most printed components sit under the hood - brackets, ducts, covers, and housings printed from ABS for its temperature resistance. Parts near the engine cooling system are printed in nylon, which handles the heat. The cockpit control grip - the thing the pilot holds for the entire flight - is printed on a Prusa resin printer. These aren't prototypes waiting to be replaced by 'real' parts. They're final production components that go into every aircraft that leaves the hangar.
Molds and master models
Before a carbon fiber composite part goes into serial production, Shark.Aero prints a master model for testing and trials. Each aircraft requires around 200 carbon composite components - the fuselage, wings, panels - all laid up by hand into molds. 3D-printed tooling helps the team prepare and verify these molds before committing to the expensive composite layup process. Getting a mold wrong means days of lost work. A printed test piece costs a few euros of filament and a couple of hours.
Workshop tooling
Beyond the aircraft itself, the workshop is full of printed tools, jigs, and fixtures that the team uses every day. Custom-shaped holding fixtures for oddly shaped composite parts during bonding. Alignment tools for assembly. Things that would otherwise need to be machined or jury-rigged out of whatever's lying around.
Development and iteration
The retractable landing gear doors took 10 years of development. Vlado Pekar describes the process as constant trial and error - countless variations printed, tested, adjusted, and reprinted. The final working doors are a hybrid of carbon composite and 3D-printed parts. The payoff: an extra 10 km/h of speed from cleaner aerodynamics. That kind of iteration would be financially impossible if every version had to be outsourced or machined.
“Who would have thought that a plane with 3D-printed parts can fly around the world?”
What makes this story relevant to your business isn't that you're building planes. It's that Shark.Aero is a small team doing exactly what you'd do with a CORE One+: printing production parts, making their own tooling, iterating on designs without waiting for vendors, and keeping manufacturing in-house. Their parts are reliable enough to fly. Yours don't have to be.

In-house 3D printing vs. outsourcing
Compare lead time, cost per part, and production flexibility.
| Production method | Lead time | Cost per part | Production flexibility |
|---|---|---|---|
| CNC machining (aluminum) | 2–6 weeks | High | Low, long waiting |
| In-house 3D printing with CORE One+ | 12–24 hours | Low | Immediate design iteration |
Cost of ownership
Here's what running a CORE One+ actually costs.
- No subscriptions.
- No licensing fees.
- No service contracts.
PrusaSlicer is free, open-source, and always will be.
One year warranty covers normal wear and tear.
With standard materials like PETG and PLA, a nozzle lasts roughly 6 months of heavy daily use.
The steel print sheet is a consumable, but a durable one.
The printer draws about 120W - roughly the same as a bright light bulb.
A 1kg spool costs $20–30 and prints dozens of parts.
Supported CAD Packages
PrusaSlicer (Print data preparation SW) is free forever. Supports data from any SW with STL, STEP, 3MF and OBJ.
“3D printer is the best tool for repairing and designing parts.”
Knorr-Bremse Rail System Denmark repairs trains by making the most of every component. They design and manufacture new parts using Original Prusa 3D printers and print materials, in particular the self-extinguishing Prusament PETG V0 filament.

About Prusa Research
Prusa Research was founded 14 years ago by Josef Prusa, one of the founding fathers of modern 3D printing. Now with a global team counting 1200 people.
We're known for building reliable, no-nonsense workhorse 3D printers, and we prove it ourselves. Our production floor runs on hundreds of Prusa printers making real production parts, jigs, and fixtures every day. If they're good enough for our own manufacturing, they're good enough for yours.
Our mission is straightforward: make high-reliability 3D printing accessible to businesses of any size, help bring manufacturing closer to where it's needed, and give companies a real alternative to depending on overseas supply chains.
Shark.Aero is a small ultralight plane manufacturer using Prusa 3D printers for prototyping, production parts manufacturing and carbon fiber mold making.
