Introduction

The main idea of this printer is to create a new design of a 3D printer with a cubic cartesian scheme which includes as many as possible parts from plastic. I.e. it supports the RepRap concept to create some kind of easy reproducible 3d printer to make it more achievable for a wide engineer society. One of the main concepts is that all plastic parts designed to be printed by one hotend 3d printer without using supports.

Main features/improvements

  1. Cubic construction – Strong and Stable
    • The cubic construction is still to be the most strong construction that provides the best quality at the cheaper cost.
  2. Simple construction – The hotbed Z-axes are the part of the construction
    • Four vertical cornels of cubic construction are the Z-axes of the hotbed. It decreases the number of parts and cost.
  3. The Hotbed can be increased – up to 240mm x 290mm
    • The nominal hotbed is 220mm x 220mm. You can upgrade up to 240mm x 290mm.
  4. The Z-axis can be increased – up to 310mm
    • The nominal Z-axis has a 310 mm length. You can upgrade up to 350mm.
  5. The belt connection is simple and confident.
  6. Almost all parts of construction made of plastic.

Development

This is the first version that represents the nominal configuration. Several parts planned to be developed such as a cable holder, filament roller holders, ventilation system for hotends. The development of the GLKLN is hosted on the: GitHub.

Bill of Materials (BOM)

The updated version of the BOM can be downloaded from the project repository on the: GitHub

Electronics

Stepper Motors

The GLKLN uses, including the two extruders, 6 stepper motors. Two of these motors, the Z-axis motors, are connected to the same stepper driver of the electronics.

Controller Electronics

The GLKLN uses MKS Gen L motherboard. Because RepRap printers compatibility it can be based on the other RepRap controller boards.

Extruder

Heated Bed

Filament Holder
