Kentstrapper launches Mille, an industrial FFF printer with a one-cubic-meter build volume

Kentstrapper, a Florence-based 3D printer manufacturer operating since 2011, launched sales of Mille on July 6, 2026, an industrial FFF printer with a 1000 × 1000 × 1000 mm build volume. The machine was previously showcased at the Mecspe trade show in Bologna in March and is now available for order at a starting price of €40,000, with each unit assembled individually in Florence. The target customers are those who currently build large parts from multiple segments and would prefer to replace that process with printing them as a single piece. This includes the automotive sector, the marine industry, aerospace, heavy engineering, production-line tooling, and defense.

A one-cubic-meter build volume itself is not new in industrial FFF. Large-format machines with similar working areas have been available from several manufacturers for years. Therefore, the number in the headline should be treated as an entry ticket into the category of large-format industrial FFF printers.

Much ado about warping

The build plate heats up to 120°C across six independent zones, and before each print, a scanner maps the entire build area geometry and automatically compensates for any irregularities. The chamber is actively heated and maintains 60°C throughout operation, which, according to the manufacturer, enables the use of materials such as ASA-CF and PPS-CF. The same 60°C threshold was already available in the smaller Bold 755, with a 700 × 500 × 500 mm build volume, but Mille scales it up to a full meter and replaces the Dragon UHF print head with the high-flow Mantis extruder, supporting nozzles from 0.4 to 1.4 mm. The magnetic S.E.M. system, already used in previous models, allows tool-free print head replacement in less than half a minute. The material list includes, among others, glass-fiber- and carbon-fiber-reinforced nylons, PPS-CF, as well as ESD materials and polymers certified according to UL 94 V-0.

Tw o extruders operate in continuous mode. When the spool in the first extruder runs out or a feeding anomaly occurs, the second extruder, loaded with the same material, takes over without stopping the print. Power-loss recovery works for prints lasting up to 72 hours, so you can leave multi-day jobs overnight without supervision.

Meet Clara

Mille connects to servers through an outgoing, encrypted Cloudflare Zero Trust tunnel without opening incoming ports and without requiring a public IP address. Every access attempt requires authentication and two-step confirmation and is recorded in an audit log. For this segment, this approach represents a rare level of attention to industrial machine cybersecurity. A dedicated Telegram bot sends notifications, provides images from the onboard camera, and distributes firmware updates via OTA.

Clara, the assistant integrated into the printer, operates on a database built from real, closed Kentstrapper service cases. It recognizes known failures and guides users toward solutions, while fleet monitoring can detect potential problems before customers notice them.

This software layer is the core of the €40,000 offer because in production, the real cost is not the price list but downtime. Kentstrapper documents its example in which tooling outsourced for €70 per unit was reduced to €20 in material costs when produced internally, while lead time dropped from three days to twelve hours. The machine qualifies for Industry 4.0 and Transizione 5.0 incentives, meaning the effective net cost after deductions can be significantly lower than the list price. The Florence-based team directly handles training and post-sale updates.

As a demonstration, Kentstrapper presented an electric vehicle battery enclosure longer than 700 mm, printed as a single piece from ASA. Normally, this component is assembled from several segments. Printing it as a single part eliminates structural seams and potential crack sites.
