Large-format 3D printing for tall, single-piece parts

The Modix BIG-120Z is a large-format 3D printer designed for tall parts in one piece. Its 600 × 600 × 1,200 mm build volume supports 1.2 m tall prints, helping reduce seams, improve part strength, and minimise post-processing.

Key features and benefits

  • GEN5 electronics: Duet 3 6HC controller, CAN bus print heads, Ethernet, a removable Wi-Fi dongle, a tool board with accelerometer, and a new touchscreen.
  • High-speed option: The optional Griffin Ultra print head can extrude up to 0.5 kg per hour and is described as up to 6× faster.
  • Modular configuration: Dual head IDEX, enclosure, and casters are optional add-ons.
  • Standard Z-axis support: HIWIN MGW linear rails are included as standard.
  • Single-phase power: The printer is available in 110 V or 230 V versions, selected at order.

Use cases for large-scale production

The BIG-120Z suits visual communication, interior design, art, mannequins, props, entertainment, and engineering. It is also suitable for users who need tall prototypes, large display models, or production parts that benefit from a single-piece print.

The printer ships as a self-assembly kit with a guided online manual and live support. Warranty coverage is 12 months plus lifetime support, excluding degradable items and consumables.

FAQ

Frequently asked

What is the Modix BIG-120Z used for?

The Modix BIG-120Z is designed for super-tall, large-format industrial 3D printing. It is commonly used for full-scale prototypes, tall industrial components, architectural models, molds, tooling, and end-use production parts.


What makes the BIG-120Z different from other Modix printers?

The BIG-120Z features an extended Z-axis build height of 1200 mm, allowing it to produce exceptionally tall single-piece prints that would normally require assembly or segmented printing on standard large-format machines.


What materials can the Modix BIG-120Z print?

It supports PLA, PETG, ABS, ASA, TPU, Nylon, Polycarbonate (PC), PP, and carbon or glass fiber reinforced composites depending on hotend configuration.


Can the BIG-120Z print industrial-grade materials?

Yes. With high-temperature hotend configurations and an enclosure, it can process engineering-grade materials such as Nylon, PC, and composite filaments suitable for functional and end-use parts.


Is the Modix BIG-120Z enclosed?

The enclosure is optional. A full enclosure is recommended for temperature-sensitive materials such as ABS, ASA, Nylon, and composites to improve print stability and layer adhesion.


What is the build volume of the BIG-120Z?

The build volume is 600 × 600 × 1200 mm, optimized for tall industrial parts and single-piece vertical manufacturing.


Does the printer support dual extrusion?

Yes. The BIG-120Z supports an optional IDEX (Independent Dual Extrusion System), enabling multi-material printing, dissolvable supports, or duplicate part production.


What slicers are compatible with the Modix BIG-120Z?

It is compatible with PrusaSlicer, Cura, Simplify3D, and other RepRap-compatible slicing software.


Is the Modix BIG-120Z suitable for production use?

Yes. It is widely used for low-volume production, manufacturing aids, jigs, fixtures, and functional end-use parts in industrial environments.


Does the BIG-120Z require professional installation?

The printer is shipped as a self-assembly kit, but professional assembly and commissioning services are available and recommended for first-time industrial users.


What industries use the Modix BIG-120Z?

It is commonly used in manufacturing, automotive, aerospace, architecture, product development, film production, and industrial design applications.


What support and warranty are included?

It typically includes a 12-month manufacturer warranty and lifetime technical support, depending on distributor and region.


Can the printer be upgraded later?

Yes. The Modix platform is modular and supports upgrades such as enclosure systems, high-flow hotends, rail upgrades, filtration systems, and dual extrusion configurations.


What is the main advantage of the BIG-120Z over standard large-format printers?

Its primary advantage is the extreme vertical build height, which allows single-piece production of tall industrial parts that would otherwise require segmentation or post-assembly.


Is it difficult to operate the Modix BIG-120Z?


It is designed for professional and industrial users. While it has advanced capabilities, features like auto-leveling, gantry alignment, and remote monitoring help simplify operation once configured.
