Rapid prototyping
Prototype in standard materials like PLA, PETG, or ASA in just hours. Bypass outsourcing delays and validate ergonomics and mechanical fit fast enough to run multiple design cycles in a single shift.
Prototype. Validate. Produce. All on a single printer
Stop burning weeks on external lead times. You can have your PLA prototype before lunch and validate functional ASA or PC-CF parts before the afternoon sync.
Switch to the magnetically attached high-temp toolhead, and deploy small to mid-sized parts with high-temp polymers like PEEK, PEKK or PEI.
Protect your intellectual property with optional fully offline operation and a removable Wi-Fi module. Keep design files, process settings, and production data inside your environment.
With HT90, anyone who can plug in a power cord can 3D print. With an actively heated chamber and a rapid cooling system, you don't need a dedicated specialist to handle even complex geometries.
There is no other printer in this price range with such capabilities
One 3D Printer covers the full product development cycle.

Prototype in standard materials like PLA, PETG, or ASA in just hours. Bypass outsourcing delays and validate ergonomics and mechanical fit fast enough to run multiple design cycles in a single shift.

Achieve production-grade results with advanced engineering polymers like PA-CF, PC-CF, and PA11. High-performance composites provide the structural stiffness and industrial toughness.

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.
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.”

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.

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.

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.
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.

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.
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 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.
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.
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.
Your design files, process parameters, and print history never leave your facility unless you choose to send them.
Prusa Research is ISO 9001, 14001, and 45001 certified, ensuring the HT90 meets the rigorous quality, environmental, and safety standards your organization demands.

The HT90's rock-solid bed and rapid cooling system handle flexibles perfectly.
By infusing polycarbonate (PC) and nylon (PA) with carbon fibers, these composites resist extreme wear and mechanical stress while drastically reducing the shrinkage and warping typical of their base plastics. Printing these highly abrasive and temperature-sensitive materials is seamless on the Prusa Pro HT90.
Aerospace-grade polymers with excellent thermal, chemical, and mechanical resistance. Carbon fiber reinforcement enhances strength, stiffness, thermal resistance, and dimensional stability. Extra lightweight material is ideal for parts in aerospace, automotive, and medical applications, and in machinery. Requires the high-temp head and active chamber heating.
Extreme thermal stability, resilience and dimensional stability makes these polymers the highest tier of advanced engineering thermoplastics. They can replace metal with strength but at a fraction of the weight. Print with the high-temp head at 500 °C nozzle temperature and 90 °C chamber.
