The Modix BIG-120X V4 is the latest iteration of the company’s large-format FDM professional 3D printing kit, a supersized version of the BIG-60 model, featuring double the volume of its counterpart. As a kit, it comes flatpack with all the necessary parts and tools. The modularized design composed of T-slot aluminum profiles and standardized parts lets you conveniently assemble the device. Also, it allows for ongoing upgrades. Considering its enormous build volume and modular construction, many would agree that it offers a really good value for money. 

Targeted to professional users, the printer's components have been selected with performance and precision in mind. The machine introduces a bunch of redesigned key components and high-grade premium parts, namely the electronic expansion board Duex 5 enabling completely automated calibration, 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. 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. It also benefits from a 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.

The printer also supports a range of upgrades and add-ons, including a renovated enclosure for enhanced temperature control and stability, high-precision HIWIN linear rails, magnetic print bed, etc. With the right set of parts and skills, you can get machine to produce similar results as assembled, industrial-level machine, but at a much better price. The V4 can be successfully used in prototyping, mold making, research and development, restoration for printing functional prototypes, end-use products, top-quality spare parts, art models, and more. Scroll down for further info.

The 120X is expected to be used by experienced makers who have the skills and patience to dial in their configuration settings to achieve the best balance between print speed, the required level of detail and part quality. Large format 3D prinitng is not an easy fit, but once you find that goldilocks zone, it would be an amazing ride. Printing large, one piece 3D models makes them stronger and saves time on post-processing. Not to mention you can print multiple smaller items in one batch production.

Ratio Product Lab realized this custom stool using the BIG-120X V3. Printed with a 0.8 nozzle at 0.6 mm layer height, it took 48 hours of print time.

The Z-axis of the printer has been upgraded, featuring strong Nema-23 motors and reliable CNC machined brackets that hold the bed firmly and add to the overall level of print accuracy.

Due to the better motors on the X axis (compared to NEMA-17 motors for the V3), the BIG-120X V4 provides much faster printing than before. The machine boasts the accelerated travel speed of up to 350 mm/s and printing of up to 250 mm/s.

Starting with the Generation 4, the Modix devices come with the electronic expansion board Duex 5, with a dedicated stepper motor driver allocated for each Z and X axis motor. Thanks to this important improvement, the printer now offers a full set of automated calibration routines, including automated bed tilt, bed leveling, gantry alignment, and Z offset calibration making for enhanced printing precision.

Another major improvement is the new Griffin printhead. Previously it was just an optional upgrade and now it comes as the default component on all the company’s V4 printers. It consists of a custom extruder made by Bondtech and a new hotend designed by Modix. The upgrade offers smart and compact design, high flow rate, increased reliability, easy swap, and great resistance to high printing temperatures, leading to overall improved user experience.

As for the upgraded optical end-stop switches, they provide more accuracy and higher level of repeatability over time, which is particularly important for printing recovery after power outages.

These are just some of the noteworthy upgrades featured by the new version.

The Modix BIG-120X V4 comes stock with 0.4, 0.6, and 0.8 mm nozzles. It is also compatible with a broader selection of tools ranging from 0.4 to 1.2 mm in diameter. You will be able to choose the best nozzle for your printing needs. The printer can be also equipped with the IDEX add-on for multi-material printing of complex internal geometries.

The print head runs on HIWIN linear rails, which makes printing reliable, fast, and precise. The motion rails along with the upgraded Trinamic TMC2660 make for extremely quiet operation and higher accuracy.

The BIG-120X V4 supports an additional enclosure composed of aluminum composite panels. Installing the enclosure results in better heat and noise insulation.

The V4 comes with a default clog detector that can detect filament run-out, under-extrusion, and hotend clogs, which allows the user to quickly fix the problem and avoid negative impact on the quality of the printed items.

Moreover, the 8 kg spool shelf add-on (purchased separately) can carry up more rolls compared to the default one (up to 3 kg). This handy expansion also helps the extruders to easily pull filament and is great for large-scale projects.
