High Strength Chassis

All Modix 3D printer chassis and frames are built using solid 40x40 T-Slot aluminum profiles. This high quality frame material gives you the rigidity necessary to print accurately and reliably over the entire build volume of even Modix's biggest printers. A 3D printer is only as strong as its joints, and the Modix team knows it. All of the Modix large format 3D printers are held together with powder coated laser cut aluminum brackets & joints. These custom made pieces are capable of keeping every joint strong and square with every change of direction of the printhead.

• Solid 40X40 T-slot aluminum profiles
• Powder coated laser cut aluminum brackets and joints
• Enclosure – Closed enclosure made of 3mm black Aluminum Composite Panels (ACP). Enclosure is an optional add-on for BIG-60, BIG-120X & BIG-120Z and a default option for BIG-Meter and BIG-180X.

High Speed Motion System

Modix’s printers are now capable of printing significantly faster than before. Travel speed of up to 350 mm/s, and printing of up to 250 mm/s.

• HIWIN MGW9H linear guide rails
• Four Z ball screws for Z axis movement. 12mm diameter, 4mm pitch
• 9 mm width Gates GT2 timing belt, reinforced with fiberglass
• Motors: X & Z Axis: NEMA-23, Y Axis: NEMA-17
• Mechanical position accuracy: X-10 Micron, Y-10 Micron, Z-0.5 Micron
• Print speed (based on 0.4mm nozzle):
  Up to 100 mm/sec – normal quality
  Up to 250 mm/sec – draft / non functional infill
  Up to 350 mm/sec – travel
  Larger nozzles normally are required to print slower but provide parts much faster due to a reduced number of layers.

Improved Rigidity & Reduced Weight

Modix Generation 4 3D printers have been modified to support faster speeds. The lightning fast print speed has been made possible thanks to strong NEMA 23 motors on the X axis instead of NEMA-17 motors.

In addition, the weight has been reduced on the Y axis as the weight of one motor is split now into two independent ones, using the IDEX setup.

The Z axis been improved with CNC machined brackets that hold the bed firmly and at a higher level of accuracy.

Premium Print Bed

High quality, low-warp print beds are incredibly important for large format 3D printers. That is why Modix only sources incredibly high-quality parts for their printbeds.

• 6.35mm thick, Alcoa Mic6 milled cast aluminum plate, made in the USA.
• AC powered bed heater 1370 Watt (1,200 Watt for 110V users). Requires a dedicated independent 15A AC source.
• Dual heating zones. Inner 200X200mm size for small objects and lower power consumption.
• Max temperature – 110oc (with enclosure)
• Print surface – PEI film with 3M high temp adhesive sheet.

Removable Magnetic Bed

This add-on will greatly improve the user experience and save you time on a daily basis. Modix’s printers are delivered by default with a PEI sheet that releases the print once the bed is cooled down to room temperature. With the removable magnetic bed add-on, users do not need to wait or work hard with a spatula and can easily and immediately remove objects after completing the print job by simply bending the spring steel plate.

This add-on includes an adhesive magnetic sheet that should be fixed to the aluminum bed plate and a removable spring steel plate that should be placed on top of it.
The flexible spring steel plate can be printed on from both sides. One side is PEI powder coated providing textured bottom surface and the other side is serviced with a smooth PEI sheet providing a glossy bottom finish.

Another advantage is with maintenance, the PEI installed on the bed plate can degrade over time. Print removal with a spatula may result in unwanted scratches that later appear at the bottom of the printed object. Replacing the PEI on the removable spring steel or even buying a spare unit is much easier than removing it from the bed plate itself.

Recommended Enclosure

The enclosure helps to improve the printer stability providing higher quality print results. It captures the heat generated from the bed, creating a passively heated chamber. This heated chamber helps to reduce wrapping and cracks due to uneven part cooling.

Enclosure made of 3mm black Aluminum Composite Panels (ACP). Enclosure is a highly recommended add-on for the BIG-60, BIG-120X & BIG-120Z and a default option for BIG-Meter and BIG-180X.

Recent Improvements

The new Modix Generation 4 enclosure enjoys a fresh updated design and has been improved by adding the following features:

• Pneumatic top lid
• Rear maintenance opening hatch
• Sturdy door hinges
• Door and lid sealing strips
• Improved internal led lighting
