Voxel2GCode

A set of workflows to transform geometric objects and voxel-based models into 3D-printable G-code instructions.

Material Gradients with Monolith

Voxel2GCode is a project which aims for a flexible, customizable workflow for 3D printing, which started as part of the Material Gradients with Monolith project by Nono Martínez Alonso while working with the Autodesk Generative Design Group, during the summer of 2016. As an effort to simplify how instructions are sent to 3D printers, the project is structured to make the implementation of custom printing and slicing workflows easy, and to fabricate artifacts from geometric objects and voxel-based models with low cost multi-material 3D printers.

In a nutshell, Voxel2GCode provides five tools:

  • Voxel2GCodeCore as a standalone .NET library.
  • Voxel2GCodeRhinoCommon for scripting with C# using RhinoCommon.
  • Voxel2GCodeGH as a Grasshopper for Rhino plugin.
  • Voxel2GCodeDesignScript for scripting with C# using DesignScript.
  • Voxel2GCodeDynamo as a Dynamo package.

Download

  • Voxel2GCode.zip
  • The voxel utilities of V2G require you to install Monolith, everything else should work fine without it.

Table of Contents

Installation

Voxel2GCode for Grasshopper and RhinoCommon

  • Copy and paste all files inside the Voxel2GCode for Grasshopper into your Grasshopper components folder -- accessible via Grasshopper > File > Special Folders > Components Folder.
  • (In case you want to use the voxel components you'd have to install Monolith.)

Voxel2GCode for Dynamo and DesignScript

  • Open a new Dynamo document.
  • Under the nodes tab, click on Import, and select the Voxel2GCode for Dynamo.dll library.
  • (In case you want to use the voxel components you'd have to install Monolith.)

Voxel2GCodeCore.dll

  • You can use the Voxel2GCodeCore.dll library, for instance, as a reference in your C# project, or to script inside Grasshopper components.
  • (In case you want to use the voxel components you'd have to install Monolith.)

Basic Usage

Here are a few examples on how to use the library for scripting, with Grasshopper for Rhino, and with Dynamo. More in detail examples are being developed.

Voxel2GCodeCore

Printing A Polyline

// Create a printer
V2GState printer = new V2GState();

// Create a printable model
V2GModel model = new V2GModel();

// Create a list of points to hold positions
List<V2GPoint> positions = new List<V2GPoint>();

// Add positions
positions.Add(new V2GPoint(25.0, 40.0, 0.0));
positions.Add(new V2GPoint(30.0, 45.0, 0.0));
positions.Add(new V2GPoint(35.0, 40.0, 0.0));

// Create a printable polyline
V2GPrintPolyline printPolyline = new V2GPrintPolyline();
foreach(V2GPoint position in positions) {
  Print(position.ToString() + " " + position.X);
  printPolyline.AddPrintPosition(position);
}

// Append the printable polylines as paths to the model
model.AppendAsPath(printPolyline);

// Create a StringBuilder to store G-code
System.Text.StringBuilder sb = new System.Text.StringBuilder();
model.GenerateGCode(sb, printer);

// Create a string with G-code
string GCode = sb.ToString();

Create a Printer with Custom Settings

// Create a printer
V2GState printer = new V2GState();

// Create printing settings
V2GSettings settings = new V2GSettings();

// Override some parameters
settings.T0Temperature = 220.0;
settings.BedTemperature = 80.0;
settings.ZOffset = 0.5;
settings.Retraction_Length = 0.3;

// Attach the settings to the printer
printer.SetSettings(settings);
