KISSlicer vs Voxelizer

KISSlicer turns STL files into printer-ready G-code and is a slicer, not a printer control app. Four Profile Wizards help configure printer, material, style, and support settings. Automatic support generation, resin slicing, and variable layer height are supported. The free plan costs nothing and allows multi-extruder printers to be used, but only one extruder can be selected for a print. Pro costs $42, paid once and enables multi-material printing, with extruders assignable to the raft, support, model, and sub-meshes. Premium costs $82, paid once and includes Pro functionality alongside listed features such as colorized meshes, texturing, dynamic density and gyroid infill, warp compensation, and curved surfaces. Profiles can be shared, and Project Files can archive print settings. The software supports Windows, macOS, and Linux; downloads are also listed for FreeBSD and Raspberry Pi. Its license permits commercial use and installation on multiple personal computers, with no time or model-size limit, and prohibits reverse engineering.

Voxelizer is Zmorph’s software for preparing jobs for 3D printing, CNC milling, and laser engraving. It turns 3D models into layers, generates G-code, and includes editing tools, 3D filters, support structures, and variable layer height. The Fab version adds CNC workflows with STEP operations, tool changes inside one G-code file, and toolpath visualization. Supported file types listed for Fab include STL, OBJ, STEP, DXF, PNG, and BMP; G-code is the listed output format. Voxelizer can map PNG and BMP images onto 3D objects for multi-material printing. Image mapping and color blending require the DUAL PRO toolhead, with the described blending supporting PLA and up to eight shades. The software supports Zmorph toolheads and workflows optimized for Zmorph printers. It is free, with no paid tiers stated. Windows and macOS are supported; Linux is described as experimental. Minimum requirements include 4 GB RAM, an OpenGL 3.3-compatible GPU, internet access, and 1280 × 720 resolution.
