gMax 2 PRO Dual 2in1

  • 3D Print up to 243°C

  • Faster dual printing
    (compared to Chimera+)

  • Single nozzle temperature 
    and nozzle size

  • Nozzle ranges from 0.2mm - 1.2mm 

  • Hassle free dual-color 3D printing

  • Ideal to print water-soluble PVA supports

  • No nozzle leveling required

Dual 2in1 Extruder

The gMax 2 PRO 2in1 with 2 inputs and 1 output provides for a much easier, faster and trouble-free dual extrusion printing experience.

The hotend will retract the inactive filament out of the way, allowing for the second filament to extrude out. The printer will simply purge out the filament to a sacrificial purge tower as it switches.

gMax 2in1 Dual Features​

  • Print up to 243°C

  • Powerful 50W heater cartridge

  • Precision engineered components

  • Easily swappable with gMax 2 PRO Single full extruder 

  • Easy dual-material and dual-color 3D printing

  • Wide range of easy-to-swap nozzles between 0.2mm - 1.2mm

Ideal for PVA Support Material

Printing water-soluble PVA as support material allows for easy support removal and provides a better surface finish that traditional support. The gMax 2 PRO Dual 2in1 was made to print PVA supports easily.

We recommend using fresh Esun or Gizmo Dorks PVA and make sure to keep it in a cool dry place with desiccants.

Industrial Glass Fiber Reinforced Composite Heated Bed

The glass fiber reinforced heated bed provides a great print surface for all types of filament.

We use a custom laser cut BuildTak G10FR4 composite heated build surface for excellent thermal stability even at high temps combined with an 800 Watt heated pad. The bed is controlled by the printer via an external Solid State Relay (SSR) with PID tuning and fuse protection.

The result is a bed that combines the thermal stability of glass and the resilience of aluminum for a perfect heating cycle. You can adjust temperatures per layer, fine tune the heating cycle and turn off the bed remotely with the gTouch Controller.

Also compatible with:

▪ BuildTak Print Surface w/ Custom gMax Graphics

▪ BuildTak PEI

▪ GeckoTek EZ-Stick Hot

▪ GeckoTek EZ-Stick Cold (Non-Heated Bed)
