Kentstrapper Mille Prints One Cubic Metre on a Desktop FDM Machine

Kentstrapper has started commercial deliveries of the Mille, a large-format FDM 3D printer with a build volume that measures exactly 1,000 x 1,000 x 1,000 mm. That is one cubic metre of printable space in a box that sits on the factory floor rather than requiring a custom installation.

What the Mille actually includes

The frame is steel, the enclosure is actively heated to 60°C, and the build plate reaches 120°C. That plate is split into six independently controlled heating zones, which matters when you are printing across a full square metre. An integrated scanner maps the bed before each print and applies automatic compensation. The bed slides out for part removal, and Kentstrapper supplies two flexible C70 spring-steel build sheets.

The extruder is the company's high-flow Mantis type, with interchangeable nozzles from 0.4 mm up to 1.4 mm. Layer heights range from 0.1 mm to 1.2 mm, so you can switch between fine surface detail and fast deposition rates. Two extruders run in parallel, and a continuity mode keeps printing if one spool runs out or the feed jams. That is useful for unattended overnight jobs on a machine this size.

Materials and connectivity

Supported filaments include PLA, PETG, ASA, ABS, and TPU. The company also lists ASA-CF, glass- and carbon-fibre-reinforced nylon, PPS-CF, ESD-safe materials, and UL 94 V-0 certified options. Connectivity covers Wi-Fi, Ethernet, and USB. The printer runs custom Klipper firmware and uses a 10.1-inch HD touchscreen. Power-loss recovery is supported for jobs lasting up to 72 hours.

Remote management and AI support

Kentstrapper's KS Ai System handles remote monitoring through an encrypted Cloudflare tunnel. Users get a Telegram bot for print notifications, camera snapshots, and status checks. Over-the-air firmware updates come through the same interface. The system also includes Clara, an AI support assistant trained on the company's historical ticket data. Clara can diagnose known problems and guide users through fixes before they need to call support.

Pricing and positioning

The Mille starts at 40,000 euros plus VAT, made to order at Kentstrapper's facility. That places it against machines like BigRep's ONE.5, which offers a near-identical 1,005 mm cube build volume. Kentstrapper's differentiators are the six-zone bed, the magnetic toolhead swap, and the integrated remote management stack.

Large-format polymer printing is still a niche, but the use case is clear: printing big functional parts as single components instead of assembling smaller sections. Kentstrapper itself demonstrated this by printing a 700 mm electric-vehicle battery enclosure in ASA as one piece.
