1984 Ingsoc logo

thingiverse

The Ingsoc logo from George Orwell's dystopian novel Nineteen Eighty-Four is a symbol of English Socialism Party. SOURCE: The design is based on the Wikipedia logo. Brief description of design process: The logo was modified and converted using Inkcape with extension for OpenSCAD into several layers and merged together using OpenSCAD. Tutorial for multicolor print using any printer: It might sound strange, but every 3D printer is capable of layer-based multicolor print by splitting the generated GCode file into multiple files. GCode files contain instructions for the printer such as movement of motors or temperature of heatbed. Never change any value in the GCode if you don't know the result. Firstly, download Slic3r or Slic3r PE to see the comment ;AFTER_LAYER_CHANGE in the Gcode file. These comments are added by Slic3r and determine where in the GCode the new layer is being changed. Secondly, slice your file using Slic3r then open the generated file in a text editor such as Notepad. Look for the comment ;AFTER_LAYER_CHANGE followed by the ;XX.X where XX.X is desired layer. For example, you want to print the first 2mm of the model in one color and the rest in another color. You are going to print the model at 0.2mm resolution. Open generated GCode and look for: ;AFTER_LAYER_CHANGE ;2.2 You just found the place where to split the Gcode file! Now, copy the lines of Gcode into a separate file and modify the GCode. Last line before the comment ;AFTER_LAYER_CHANGE tells the printer to move in the Z axis. To simplify filament replacement, increase that value a bit. For example: [BEGIN] ... G1 E-0.04000 F2100.00000 G1 Z2.600 F10800.000 <i>move in Z axis to position 2.6mm</i> ;AFTER_LAYER_CHANGE ;2.2 ... Split the GCode into two files and modify the Z position in the first file. part1.gcode: [BEGIN] ... G1 E-0.04000 F2100.00000 G1 Z5.2.600 F10800.000 <i>move in Z axis to position 52.6mm</i> ;AFTER_LAYER_CHANGE ;2.2 part2.gcode: G1 Z2.600 F10800.000 <i>reverting the changes from file1.gcode</i> ;AFTER_LAYER_CHANGE ;2.2 ... Lastly, print split files and voila you have your multicolor print. Recommendations and warning: Watch your printer during the first multicolor print. I have no responsibility for possible damage on your print.
