Industrial strength
Achieve production-grade results with engineering polymers like PA-CF, PC-CF, and PA11. High-performance composites provide the structural stiffness and industrial toughness.
End‑use production
Switch to the high-temp toolhead and unlock the capability to print PEEK, PEKK, and ULTEM – small-to-mid-sized components with the extreme thermal and chemical resistance needed for aerospace and medical applications.
PA11 | ABS | ASA
Engineered for High-Impact Strength
The Prusa Pro HT90 utilizes its actively heated 90°C chamber to flawlessly print production-grade polymers like ASA and PA11. This controlled thermal environment unlocks the full mechanical potential of these materials, enabling the on-demand manufacturing of rugged personal protective equipment (PPE) and industrial shielding.
The resulting prints deliver exceptional impact strength and tensile characteristics. Because of these properties, the material is especially suitable for producing mechanical parts and other models where durability is key. In addition to absorbing kinetic energy without shattering, the filament also provides good friction and abrasion resistance. This ensures your functional safety gear easily withstands sudden blows and intense mechanical stress on the factory floor.
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.”
HT90 is TAA compliant, which is required for US government and federal contractor purchases.
IN-HOUSE PROTOTYPING WITH HT90
Gain a competitive edge
Imagine a scenario where your competition waits weeks for their prototyping molds. Your team has a functional prototype ready just hours after the initial idea. You can iterate in real time and reduce lead times by 95%.
You can also achieve an 80% or more cost reduction per part. HT90 users achieve full ROI on an HT90 printer in months, or even weeks.
Two print heads. One machine. Full material range
Master the industrial‑grade polymers
The Prusa Pro HT90 is your cost-effective gateway to high-performance polymers. Its 500 °C nozzle and 90 °C active chamber provide the ideal environment for industrial-grade ASA and PC-CF, alongside specialized production of small-to-mid-sized PEEK and PEI parts. Achieve perfect structural integrity and stability that meets the highest industrial standards.
Switch to PLA prototyping in seconds
Need one more rapid iteration or want to test a quick idea? The HT90 eliminates downtime with its magnetically swappable print heads, allowing your team to transition from high-temp engineering materials to high-flow PLA in seconds. Simply snap the new print head into place and keep your workflow moving.
Print fast and precise
Thanks to delta kinematics, the HT90 achieves ultra-fast speeds with maximum acceleration of 20,000 mm/s while delivering smooth, dimensionally precise prints across the entire cylindrical print area. A unique rapid cooling system redirects airflow to precise areas of the model within milliseconds, enabling flawless overhangs and complex geometries with minimal supports. It also prevents overcooling of the rest of the model to preserve the polymer's optimal mechanical properties and superior performance.
Industrial‑grade, desktop footprint
The HT90 brings factory-level reliability straight to your workspace. Its actively heated chamber holds temperatures uniformly, ensuring that print even with advanced and high-temp materials won't warp or delaminate mid-print. At the same time, the integrated HEPA and activated-carbon filtration system safely captures harsh particulates and VOCs, allowing the printer to run safely in any office or lab environment without the need for dedicated ventilation infrastructure.
Keep your data safe
For defense, medical, and high-tech R&D environments, the HT90 supports fully offline workflows and does not require any network connection. Your G-code, process data, and sensitive IP remain under your direct control.
“We designed the aircraft around the HT90's capabilities to minimize cost and maximize performance. Switching to injection molding would increase weight and tooling costs – making it a non-starter.”
3D-printed structural parts enable rapid iteration on life-saving drone designs.
Angel Aerial Systems
Drones built to save lives, parts built in-house
Angel Aerial Systems produces unique drones for critical, life-saving missions — achieving 2 hours of hover time, three to six times longer than traditional quadcopters.
That level of performance requires continuous structural and thermal optimization. With traditional manufacturing, each design change means a quote, lead time, and delivery delay. With the HT90, it means a file update and an overnight print. As the CEO Will Hasting puts it: 'We've run hundreds of design iterations, it would have taken years and cost exponentially more with traditional manufacturing.' The HT90 lets a small team iterate at a pace that would otherwise be difficult to sustain.
Securing your data is our top priority
In high-stakes industries such as aerospace, defense, and advanced R&D, data security is a core requirement. The HT90 is built to keep your intellectual property under your control.
Full offline operation
The HT90 can run fully offline for setup, slicing, and printing, with a physically disconnectable Wi-Fi module. No mandatory telemetry and no forced cloud activation.
IP stays in‑house
Your design files, process parameters, and print history never leave your facility unless you choose to send them.
ISO certified
Prusa Research is ISO 9001, 14001, and 45001 certified, ensuring the HT90 meets the rigorous quality, environmental, and safety standards your organization demands.
