Modix BIG-120Z V4 3D Printer Review

Updated Sep 28, 2020 11789

Build volume is an important thing to consider when shopping for a 3D printer. Bigger is not always better, but for industrial, professional, and commercial machines it might as well be. Modix BIG-120Z occupies a rather specific niche of machines that are both massive in the height department and compact enough when it comes to footprint, offering the ability to produce quite large prints at competitive price. 

Pros and cons
  • Massive build volume
  • Dual extrusion
  • Ability to print very tall objects
  • Enclosed design
  • Support for a wide range of filaments
  • Ability to keep high temperatures consistent and stable
  • Large size, although the overall footprint is not that huge
  • Takes a long time to assemble




About Modix

Modix is an Israeli startup based in Tel Aviv. Founded in 2014, the company went on to release their first 3D printer just a year later. The model was named Agam and served as a successful educational model that is still used by various institutions.


Nowadays, the company focuses solely on their ‘BIG’ series of affordable modular 3D printers with large build volumes that includes several generations. The V4 upgrade pack has introduced all sorts of advanced capabilities and neat modifications making the Modix devices even more precise, fast, reliable, and user-friendly than before. To find out more, check out the video below.


Modix BIG-120Z V4 Overview

The BIG-120Z is the latest iteration of the company’s ‘BIG’ series of large-format 3D printers. Due to its impressive vertical size with the build volume of 1200 mm along the Z-axis (hence the name), the device stands out for its capability of printing super-tall objects in one piece. Thus, it effectively combines a huge build area with brand upgradable structure, which leaves room for a wide range of add-ons to amplify the user’s printing opportunities. 

As a part of the Generation 4 of Modix 3D printers, the BIG-120Z model introduces a bunch of redesigned key components and high-grade premium parts, namely the electronic expansion board Duex 5 enabling completely automated calibration, upgraded Griffin printhead, stronger Nema-23 motors and CNC machined brackets for much faster and more stable printing, optical end-stop switches for higher accuracy and repeatability, improved PTFE tube and wires management for smooth and convenient maintenance, built-in crash detector for additional safety, and an integrated emergency stop button ensuring immediate response. 

As one of the tallest models, the BIG-120Z is now supplied with a new standard add-on, including a handy tilt screen ensuring easier access to information and commands, especially during system calibration, frontal secondary power switch for convenient operation in tight spaces, and secondary reset button for even better comfort of use.

In addition, all the Generation 4 models boast updated design features, such as a pneumatic top lid, rear maintenance opening hatch, sturdy door hinges, door and lid sealing strips, and improved internal LED lighting.

Also, the printer supports an additional enclosure composed of aluminum composite panels. Installing the enclosure results in better heat and noise insulation.

The BIG-120Z benefits from a default filament sensor, which keeps track of potential clogging, and Wi-Fi connectivity for remote control.

Moreover, the company has released a brand new IDEX add-on, which opens up new possibilities for printing with independent dual extruder and water-soluble filaments.
