Power R&D Performance and Scale a Factory Floor
Accelerate product development and streamline production with an industrial-grade platform built for advanced polymers, precision delta kinematics, and uncompromising data security.
High-Performance Polymers
Unlock demanding engineering materials like PEEK, PEKK, PEI (Ultem) (small-to-mid parts), and carbon-fiber composites using a 500 °C high-temperature nozzle. Produce chemically and thermally resistant fixtures, valves, or aerospace-grade components directly in-house without external vendor delays.
High-Volume Production
Eliminate supply chain bottlenecks by producing large components or multi-part batches internally. Featuring a Ø300 × 400 mm cylindrical build volume and print head accelerations up to 20,000 mm/s², the static bed design ensures dimensional stability, superior surface finishes, and tight tolerances for demanding industrial applications.
Maximum Layer Integrity
Prevent warping and material deformation during complex builds. The fully insulated, actively heated 90 °C chamber maintains uniform ambient temperatures, delivering optimal layer fusion and structural integrity required for heavy-duty ABS, ASA, and polycarbonate parts.
Complex Geometries
Drastically reduce post-processing labor and support material usage. An advanced high-pressure turbine and dynamic servo-shutter cooling system direct airflow precisely where needed within milliseconds, enabling clean overhangs and internal channels without chilling the ambient chamber.
Air-Gapped Data Security
Keep proprietary CAD files, prototypes, and manufacturing data strictly within your corporate network. Engineered around an offline-first architecture, the system operates via USB drive or optional local network connectivity, satisfying strict enterprise IT security requirements without forced cloud exposure.
Integrated Filtration
Deploy additive manufacturing directly into engineering labs and office workspaces without compromising air quality. A fully enclosed recirculation system uses HEPA and active carbon filters to scrub ultrafine particles (UFPs) and VOC fumes during high-temperature polymer processing.

1 / 6
Accelerate hardware engineering from initial fit checks to final deployment
A single platform handles early concept validation through high-stress production tooling.
Industrial Strength
Print structural composite parts using carbon-reinforced polymers such as PA-CF and PC-CF. The chopped fiber reinforcement significantly increases tensile modulus and prevents thermal distortion during high-load operation.
End‑Use Production
Mount the high-temperature printhead to process PEEK and ULTEM for demanding industrial applications. These advanced thermoplastics provide the chemical resistance and heat deflection needed for high-stress flight or automotive environments.
Plus de 110 000 entreprises dans le monde nous font confiance.
Conçue pour les entreprises exigeant une fiabilité et une sécurité des données élevées.
“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.”
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).
HT90 is TAA compliant, which is required for US government and federal contractor purchases.
“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.”
