Best 3D foam cutting machine

Mammut CNC foam wire cutter

Mammut by Nettuno Sistemi is engineered for industrial foam fabricators, prototyping workshops, and architectural model shops seeking a high-throughput 3D foam cutting machine and precision CNC foam wire cutter capable of both large-format and fine-detail work.

Our best CNC foam wire cutter adapts seamlessly from rough industrial cuts to delicate 3D filigree, making it a versatile asset for any operation focused on efficiency, accuracy, and rapid changeover between jobs.

Our 3D foam cutting machine

Completely redesigned and renewed, Mammut inherits the glorious legacy of the Infinity model, integrating years of experience and success to offer unmatched performance and innovations.

Thanks to its modular structure, a must-have series of accessories, and the ability to vary the cutting wire length, this 3D foam cutting machine has revolutionized the working methods of all operators in the cutting and processing of expanded polystyrene (EPS), ensuring the maximum flexibility and capability for every processing need.

Hot wire foam cutting area

Representing advanced capabilities in foam fabrication, the Mammut is a prime example of a large-format 3D foam cutting machine. Utilizing precise hot wire cutting foam technology, this type of CNC hot wire cutter offers a substantial and versatile work envelope, with typical dimensions like 3020 mm (X), 1250 mm (Y), and a Z-axis extendable from 1300 mm up to 4500 mm.

Features such as a modular structure sliding on high-precision, floor-anchored guides are common in high-end models like the Mammut, allowing for rapid extension to accurately process very long foam blocks (e.g., up to 4.5 meters).

This makes such a hot wire foam cutter exceptionally suitable for demanding industrial projects requiring significant flexibility, large-scale capacity, and unwavering cutting precision.

Mammut is versatile

Unlimited wire inclination

5 independent axes hot wire foam cutter

The Mammut isn’t limited by conventional cutting angles. Featuring 5 independent axes of control and equipped with Nettuno’s proprietary automatic wire tensioning system, it allows for virtually unlimited wire inclination, reaching the maximum possible diagonal across the cutting area.

This advanced capability empowers you to execute extremely complex cuts, intricate shapes, and sharp angles that are simply unattainable with standard machinery, opening up new possibilities for your designs.

Smart temperature regulation

A microprocessor-based current regulation system ensures precise thermal stability of the foam cutting wire. This closed-loop control actively compensates for input voltage variations and dynamic changes in effective wire resistance (resulting from tension and length variations), thereby maintaining consistent cutting energy delivery and optimal operational parameters.

3D hot wire foam cutter transmission

The system’s actuation relies on brushless motors featuring absolute encoders for closed-loop position control. Linear motion is achieved through a configuration of high-stiffness linear guides, low-friction carriages, and a precision ball screw drive, delivering both smooth travel and high repeatability during foam cutting operations.

Pneumatic work-holding tabletop

The CNC 3D foam cutting machine utilizes four steel/marble composite sliding tabletops integrating a pneumatic locking system for secure work-holding.

Motion along the primary axis is facilitated by linear guides with recirculating ball bearings. Integrated end-rollers are included to improve the efficiency of loading expanded polystyrene blocks onto the support platform.

Level up with our professional accessories

4-axis milling router

Create amazing custom sculptures in 360°. Use the rotation of the horizontal lathe and the 4-axis movement of the milling machine to carry out the operations.

Multiple wire harp

It can cut polystyrene blocks with more than one wire simultaneously, processing multiple pieces of the same shape in a single movement.

Main rotating table

The rotation occurs automatically and is managed by the software interface. It allows cuts along all four sides of the polystyrene block without the need for manual rotation.

Vertical turntable

Used for 360° cutting of 3D shapes in polystyrene, whether they are symmetric or asymmetric, irregular, spheres, columns, characters, and figures.

Horizontal lathe

The horizontal lathe, unlike the vertical one, is equipped with a tailstock that allows the processing of the polystyrene block at 360° along the entire length of the machine.

Tangent carver

The tangent carver uses a rigid, moldable wire that can be used to create completely customized internal excavations and perform curved cuts on a tangent, opening up new creative and productive possibilities.

Standard carver

The carver uses a rigid wire that can be manually shaped according to your needs, allowing you to create cavities within pre-shaped forms or produce unique and customized shapes.

Clevel

Automatic wire speed adjustment system. It prevents errors, inaccuracies, and defects caused by a cutting speed that has not been determined through proper checks and controls.

Extra tabletops

The basic configuration includes 4 sturdy support tabletops with pneumatic locking on guides, however, Mammut offers the possibility to add from 1 to 3 additional support tabletops.
