Kentstrapper Mille Review: A $46,000 Industrial 3D Printer That Prints a Full Cubic Meter

Italian manufacturer Kentstrapper has put its largest 3D printer yet into full production. The Mille is a large-format FDM system with a 1,000 x 1,000 x 1,000 mm build volume, an actively heated chamber reaching 60C, a six-zone bed capable of 120C, and the company's high-flow Mantis extruder with interchangeable nozzles from 0.4 mm to 1.4 mm. The starting price is around $46,000 (EUR 40,000 ex-VAT), and each unit is assembled by hand in Florence.

The pitch is single-piece production. A 1,000 mm cubed volume means structural components, large jigs, tooling, and full-scale prototypes can come off the bed without the seams and crack sites that appear when bonded sections fail. Kentstrapper targets automotive, marine, aerospace, defense, and heavy engineering users who currently split large parts across multiple smaller prints and assemble them afterward.

What You Get for the Price

The Mille uses a rigid steel-frame Cartesian system. The print bed slides out for part removal, a practical touch on a machine this size. The Mantis extruder reaches 400C and supports layer heights from 0.1 mm to 1.2 mm, so you can choose between fine surface detail and thick-layer throughput for larger parts. Nozzle options up to 1.4 mm let you push material faster when surface finish is not the priority.

Connectivity covers Wi-Fi, Ethernet, and USB. The machine runs custom Klipper firmware with a 10.1-inch HD touchscreen and an optional webcam for remote monitoring. Automatic power-loss recovery handles jobs up to 72 hours, which matters when a single large print runs overnight or over a weekend.

Material Range

Kentstrapper lists PLA, PETG, ASA, ABS, TPU, ASA-CF, glass-fiber nylon, carbon-fiber nylon, PPS-CF, ESD-safe materials, and UL 94 V-0-certified filaments as tested and supported. That is a strong range for an industrial FDM system, and it covers most functional and tooling applications without requiring material experiments.

How It Compares

A sub-$50,000 entry point for a full cubic meter of actively heated build space is competitive. Some large-format FDM systems in this class carry six-figure price tags, and lower-cost alternatives often sacrifice chamber temperature, bed zone control, or material support. The Mille's main constraints are the same as any machine in this format: footprint, power requirements (380V three-phase, 18A, 7,000W), and the fact that large-format FDM demands process knowledge that does not transfer directly from a desktop printer. Users who have only run 250 mm Cartesian or CoreXY machines should expect a learning curve on bed adhesion, thermal management, and material behavior at scale.

The Verdict

The Mille is a credible entry in the industrial large-format FDM segment. Its made-in-Italy build quality, dual-extruder redundancy, and strong material support make it a serious option for shops that need to print large functional parts in one piece. The price is realistic for what you get, and Kentstrapper's track record since 2011, with over 2,500 systems sold, suggests the company understands professional users. The absence of a published shipping timeline is the main unanswered question for anyone ready to place an order.
