Prusa CORE One+ Business | Professional Enclosed CoreXY 3D Printer

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.”

Customer Story

Over 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.

3D-printed components used in Shark.Aero aircraft

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.

Carbon fiber mold preparation at Shark.Aero

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.

Shark.Aero workshop and iterative development

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?”

Petr Hýl — Petr HýlSales Director, Shark.Aero

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

We often hear from our customers that Prusa printer pays for itself in first three months.

Cost of ownership

Here's what running a CORE One+ actually costs.

No subscriptions.
No licensing fees.
No service contracts.

Software

PrusaSlicer is free, open-source, and always will be.

More details

No per-seat licenses, no annual renewals, no cloud subscription. Updates are free forever.

$0/year

Warranty & support

One year warranty covers normal wear and tear.

More details

24/7 tech support included, with service centers in Prague and the USA. Extended warranty available for $154.99/year after the first year.

But here's the thing - you'll rarely need us. CORE One+ is designed to be self-serviceable. Every common maintenance task can be done by the user, no special tools, no technician visit. Swap a nozzle in 2 minutes. Replace a fan in 10. We publish step-by-step guides for everything.

This isn't something we bolted on as an afterthought. We've spent 14 years selling to home users and hobbyists - people who expect to maintain their own machines. That discipline shaped how we engineer every part of the printer. The result is a machine that's genuinely easy to keep running, even if you've never touched a 3D printer before.

Nozzles

With standard materials like PETG and PLA, a nozzle lasts roughly 6 months of heavy daily use.

More details

Swap takes 2 minutes. With careful use and non-abrasive materials, nozzles can last well over a year. If you print abrasive materials like carbon fiber fill, you'll want a hardened nozzle (~$27) which lasts even longer.

~$20 every 6+ months

Print sheets

The steel print sheet is a consumable, but a durable one.

More details

Under heavy daily use, expect to replace it about once a year. Many users get significantly more life out of theirs - proper cleaning and handling go a long way.

~$30/year

Electricity

The printer draws about 120W - roughly the same as a bright light bulb.

More details

Running it 8 hours a day, 250 working days a year, that's around $45 in electricity depending on your rates.

~$45/year

Filament

A 1kg spool costs $20–30 and prints dozens of parts.

More details

Your actual spend depends entirely on what and how much you print. Most SMB users spend $50–150/month.

Year one total:printer + roughly $150–250 in consumables.

Year two onward:$150–250/year. That's it.

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.
