Iota is a voxel based slicer that can handle textured meshes for 3d printing. Iota can generate image slices for inkjet/powder based machines, GCode files for color FDM/FFF printing with multiple extruders and mixing extruders, and DXF files for creating stacked models with laser cutters.

Iota will be an easy-to-use system for the colorful future of 3D printing.

First ever Iota generated color printout (XYZPrinting DaVinci Duo, dual extruders)

Voxels is short for VOlumetrix piXEL, pixels in 3D space. Iota works by converting 3D vector based models into slices of 2D image data. Multiple slices in Z form a complete voxel model.

Current 3D formats only represent the outer shell of 3D objects. Most formats use triangles or a superset like polygon meshes or lattices. A common alternative, Constructive Solid Geometry, has other limitations.

Voxels represent the entire volume of models, including inside structures, varying materials inside a model, colors and transparencies.

Iota currently generates G-Code files for DaVinci Duo printers with Repetier firmware. If will probably run with little or no modifications on other FDM printers as well.

• v0.0.10a
  • generating lids and bottoms (different lid styles)
  • range slider to better inspect extruder preview
  • converted entire OpenGL based slicing to CPU based slicing for compatibility, less memory use, and higher speed.

  • implemented some aspects of the future menu system
• v0.0.7a
  • fixed STL importer to better differentiate binary and ASCII STL files
  • rewrote the mesh fixer to reliably create watertight models every time
  • using half-edges instead of edges to represent triangle meshes
  • remember main window position and size
  • progress bar for slicing
• v0.0.6a
  • https://github.com/MatthiasWM/IotaSlicer/releases/tag/v0.0.6a
