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.
All Chinese companies are required to cooperate with state intelligence (National Intelligence Law, 2017), hand over encryption keys (Cryptography Law, 2020), and provide data to authorities regardless of where it's stored - even on EU or US servers (Data Security Law, 2021). Product designs and 3D models a legitimate target too (2023 Counter-Espionage Law update).
“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.

“3D printing saves us about 100 work hours per aircraft. The printer just runs next to the workshop - no special operator, no special department.”
Shark.Aero is a small ultralight plane manufacturer using Prusa 3D printers for prototyping, production parts manufacturing and carbon fiber mold making.
CEO, Shark.Aero
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.

Questions?
Answers for engineers and production teams.
Are 3D printed plastic parts strong enough for real-world manufacturing?
Yes, absolutely. Modern engineering filaments like PETG, ASA, and nylon (PA-CF) produce structural parts that handle extreme mechanical loads, high heat, and chemical wear. These are used daily on factory floors as jigs, alignment fixtures, robotic grippers, and durable end-use brackets. For high-temp or high-stress environments, they are a lightweight, cost-effective replacement for metal parts.
What is the dimensional accuracy of the Prusa CORE One+?
The Prusa CORE One+ achieves an exceptional dimensional accuracy of ±0.1 mm on mechanical features, which is highly repeatable. For tight press-fits or bearing mounts, you can easily run a quick test slice in PrusaSlicer in seconds. Since a test print costs pennies and takes under an hour, dialing in precise engineering tolerances is incredibly fast.
How fast can I print parts in-house?
Most standard functional fixtures or mounts print in 1 to 3 hours. Smaller parts like clips or pins can take just 15–30 minutes, while complex, full-build plates can run safely overnight. Because the printer runs entirely unattended with automated error detection, your engineers can send files in the afternoon and collect finished components first thing in the morning.
What engineering materials does the enclosed printer support?
The fully enclosed chamber and direct-drive extruder let you reliably print PLA, PETG, ASA, ABS, Polycarbonate (PC), Polyamide/Nylon (PA), Flexible TPU, and advanced composites like Carbon Fiber (CF) and Glass Fiber (GF) filled materials. The active chamber temperature management prevents warping, which cheaper open-frame printers cannot handle.
Does our team need a dedicated operator or specialist to run it?
No. The Prusa CORE One+ is built specifically for engineers, designers, and floor technicians, not dedicated 3D printing operators. The automated calibration (Mesh Bed Leveling, active flow calibration) and the pre-configured profiles in PrusaSlicer make starting a print as easy as using an office paper printer. We also include a comprehensive online training and certification course with every printer to get your entire staff confident on Day 1.
Is the printer secure and TAA Compliant for government contracts?
Yes, the Prusa CORE One+ features fully local, offline operation. It does not require any active internet connection, cloud logins, or external server uploads. Your intellectual property, CAD files, and network security remain completely under your roof. It is also 100% TAA Compliant, making it ideal for US military, government, and highly secure defense contractor environments.
