What Voxelizer is
Voxelizer is Zmorph’s free software for preparing 3D printing, CNC milling, and laser engraving jobs. It slices 3D models into layers and generates G-code, with tools for editing, applying 3D filters, and adding support structures. It can project PNG and BMP images onto 3D objects for multi-material printing; image mapping and color blending require the DUAL PRO toolhead, and the described blending supports PLA in up to eight shades. Zmorph’s Fab version adds CNC workflows, including STEP operations, tool changes within one G-code file, and toolpath visualization. Its product page lists STL, OBJ, STEP, DXF, PNG, and BMP as supported file types. Voxelizer supports Zmorph toolheads and has workflows optimized for Zmorph 3D printers. Windows 7 or later 64-bit and macOS 10.13 or later are listed minimums; Linux is experimental. Minimum requirements include 4 GB RAM, an OpenGL 3.3-compatible GPU, internet access, and 1280 × 720 resolution. Zmorph Academy offers courses on topics including voxel precision, custom G-code, and diagnostics.
