Continue Shopping or View Cart


The Velleman Vertex K8400 Three Dimensional (3D) printer is the next generation Velleman 3D printer kit. Easy, accurate, affordable and open source. The K8400 is easy-to-assemble and offers features that rival those of printers that cost up to three times as more!


Create precise 3D prints with 1.75mm filament and 0.05mm layer resolution. Reaching up to temperatures as high as 270°C, the Vertex printer can print PLA (Polylactic acid) and ABS (Acrylonitrile Butadiene Styrene), as well as other plastics.


The K8400 3D Printer Kit comes standard with an LCD backlit screen from which you can command stand alone printing. Stand alone printing allows you to control every aspect of your printing job, print from an SD card, and refill filament using simple commands. The Vertex K8400 is compatible with all common and freely available open source 3D printer software packages.


The extruder on the K8400 is stainless steel with a filament pulley wheel. Use the built-in setting for loading and unloading filament for your creations. The extruder is ultra-reliable with 1.75mm filament. See below for additional extruder option, which you can add on to the K8400 to make it capable of printing two colors simultaneously.


The K8400 platform is made up of a 4mm aluminum frame (fixed), 4mm glass plate (removable), and Buildtak sheet. The platform frame is level and sturdy, while the Buildtak sheet on top makes the ideal print surface. View below for information on additional Buildtak print surfaces for your printer.


K8400 bearings are easy-to-maintain plastic and remain silent while create with your Vertex. Bearings and Z axis are manufactured to provide ultimate stability in your 3D print space.
