FlashForge Inventor II Highlights

  • Build Volume: 5.9 x 5.5 x 5.5″
  • 50-400 Micron Layer Resolution
  • Single Extruder Nozzle
  • Print from USB, Wi-Fi, and SD Card
  • Uses 1.75mm PLA Filament
  • Closed Print Chamber
  • Intelligent Door
  • Smart Support
  • Print Larger Designs with Multiple Jobs
  • Windows, Mac, and Linux Compatible


Designed for children and beginners who are looking to venture into 3D printing, the Inventor II 3D Printer from Flashforge packs many safety features due to the hot temperatures of the build chamber. An intelligent sensor on its door automatically stops printing when the door is opened or closed, and the print head is enclosed to help protect prying hands from its heat. The Inventor II is only compatible with 1.75mm PLA filament, which is biodegradable, making it safe for use indoors, such as in classrooms. It also operates quietly with levels of 50 dB, so teachers can continue lecturing while prints are being made.

The Inventor II 3D Printer features Fused Filament Fabrication (FFF) printing technology, a build volume of 5.9 x 5.5 x 5.5″, and a layer resolution of 50-400 microns. It is equipped with a single extruder nozzle and an enclosed print chamber. Users may print their compatible .stl, .obj, .3mf, .ffp, .g, and .gx files via wired USB connectivity, Wi-Fi, or an SD card using FlashPrint printing software. The Inventor II is compatible with Windows 10, 8, 7, Vista, and XP, Mac OS X, and Linux.
