Rapid prototyping
Build functional prototypes in PETG or ASA within hours. Fast draft printing lets you verify mechanical tolerances and ergonomic handling across several iterations per day.
From early concept models to warp-free structural housings and assembly fixtures. Stop waiting on external suppliers or expensive tooling, print functional parts in-house.
The Prusa Pro HT90 bridges the gap between rapid iteration and industrial production.
With an actively heated chamber at 90 °C, HT90 extrudes engineering polymers (ABS-FR, PC, PA-CF) flawlessly, without thermal warping or layer separation.
With a 500°C High-Temp nozzle, the HT90 can print small-to-mid-sized parts using high-temp materials such as PEEK, PEKK, or PEI.
Validate designs the same afternoon, replace legacy injection molds, and manufacture end-use components under your own roof.
Designed for companies that need high reliability and data security.







These teams already run our printers in production. The HT90 is built for the same kind of work.

Angel Aerial Systems
The entire airframe is printed on the HT90. Including wings, hub structures, and more.
“We constantly balance size, weight, durability, and thermal performance under tight timelines and high reliability demands. The HT90 allows us to move quickly without compromising material properties, producing flight-ready parts that endure harsh operational conditions.”
American-European company with manufacturing in Wilmington and Prague. Everything we do, we do in-house - including the production of our own electronics on our SMT line. The entire production chain is under our control.

From rapid draft prints to warp-free engineering polymers, the HT90 provides the thermal environment and volume needed to bring serial production in-house.
“The print (PEEK-CF) was completed without any issue at all. There was no warpage, and the model stuck perfectly on the plate.”


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.

Build functional prototypes in PETG or ASA within hours. Fast draft printing lets you verify mechanical tolerances and ergonomic handling across several iterations per day.

Carbon-fiber composites like PA-CF and PC-CF yield stiff, lightweight assembly fixtures that withstand daily mechanical stress without flex.

Installing the high-temp toolhead enables printing in PEEK and ULTEM when custom parts require high chemical resistance and continuous heat tolerance up to 250 °C.
“Siemens has selected Prusa as a trusted partner and preferred supplier of professional-grade 3D printers for manufacturing aids and prototypes production. We greatly appreciate Prusa's reliable data handling, printing performance and durability.”
Everything is optional and there are no vendor locks. You can use any 1.75mm filament and third-party software if you like.
Moisture-sensitive filaments require active management. These accessories are designed specifically for the materials the HT90 runs.
Bridging the gap between desktop and industrial 3D printers, the HT90 offers an unprecedented entry point into the world of high-performance polymers. By providing industrial-grade PEEK capabilities at a fraction of the cost of legacy systems, it removes the financial barriers to high-performance and flexible R&D. Prusa Pro HT90 also integrates seamlessly into your existing engineering workflow.
From flawless prints with ABS, ASA, PC-CF, PA-CF to small to mid-sized PEEK, PEKK, and PEI components, the HT90 handles the full spectrum of engineering materials.
Basic polymers for a fast, cost-effective design iteration and everyday functional parts. Churning through these design cycles is incredibly fast on the Prusa Pro HT90, allowing your team to easily validate ergonomics, lock in perfect tolerances, and finalize designs in a matter of hours.
Industry standard for tough, impact-resistant functional parts that need to withstand thermal stress and mechanical wear. Prusa Pro HT90 handles them effortlessly. Its actively heated chamber maintains a perfectly stable environment for stress-free, dimensionally accurate prints.
Elastic materials bridge the gap between rubber and plastic. These flexible polymers deliver extreme elasticity, impact absorption, and tear resistance, making them perfect materials for gaskets, grips, vibration dampers, and wearable components. 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.
Commercial purchases include a 1-year business warranty alongside a 60-day return window. Our technical support team operates 24/7 across seven languages, staffing real operators who assist with setup, slicing settings, and material handling.
