Modix BIG-120X V4 3D Printer Review

Updated Sep 03, 2020 13128

Only a decade ago, 3D printing was much more expensive. Even the most basic machines producing simple models at a rather low quality were not exactly affordable. The times are changing, and nowadays you can buy a large-volume machine providing an industrial-grade print quality for a budget price. The Modix BIG-120X V4 is one such device. Its massive build volume, sturdy frame, and flexible construction are nicely accompanied by high-precision printing capabilities. 

Pros and cons
  • Affordable (for its size and quality) price
  • High precision along the Z-axis
  • Modular design
  • Extremely rigid frame
  • Takes a long time to assemble
  • The design is open by default but an optional enclosure is available for purchase


About Modix

With its headquarters in Tel Aviv, Israel, Modix was founded in 2014. The company released its first 3D printer called Agam in the following year. After that, the brand changed its course to focus on the large-scale FDM 3D printers, which marked the beginning of the ‘BIG’ series extending over several generations.


Currently, it is about the Generation 4, which comes with all sorts of technical tweaks and modifications making the Modix devices even more precise, fast, reliable, and user-friendly. Apart from upgraded functionality and new components, the V4 machines come with improved supply kits including some previous add-ons that are now available by default. To find out more, check out the video below.


Modix BIG-120X V4 Overview

The Modix BIG-120X V4 is a supersized version of the BIG-60 model, upgraded edition of the BIG-120X V3 3D printer, and overall perfect addition to the company’s ‘BIG’ series with its impressive build volume of 1200 x 600 x 640 mm. Alongside this distinctive feature, the machine boasts an extremely sturdy frame made of high-quality aluminum profiles and featuring laser-cut powder-coated brackets, heated print bed with a fully automatic leveling, and a 7" LCD touchscreen that offers a great level of control. 

As a part of the Generation 4 lineup, the BIG-120X supports all the recent innovations introduced by Modix. These include strong Nema-23 motors for the Z-axis ensuring higher level of print accuracy, upgraded X-axis providing the accelerated print speed of up to 250 mm/s, and reliable CNC machined brackets for increased stability. 

In addition, the V4 version is engineered with the electronic expansion board Duex 5 that offers a full set of automated calibration routines, upgraded Griffin printhead featuring high flow rate as well as increased reliability and longer service life, accurate optical switches with better repeatability and smoother print recovery after power outages, and general design changes for smooth and convenient usage. The latter include a pneumatic top lid, rear maintenance opening hatch, sturdy door hinges, door and lid sealing strips, improved internal LED lighting, convenient PTFE tube and wires management.

The Modix BIG-120X V4 comes as a DIY kit, which is easy to assemble due to standardized parts. The printer’s modular design allows for potential upgrades in both configuration and hardware with no need to buy a new machine in the future. Although the machine has an open construction, a dedicated enclosure for enhanced temperature control and stability is available as an option as well as some other add-ons, such as the IDEX (independent dual extruder) module, high-precision HIWIN rails, magnetic print bed, tilt screen, and casters. All these devices can be purchased separately to improve one’s user experience with the BIG-120X V4 3D printer.
