What Repetier-Host is
Repetier-Host is free 3D printer software for preparing and producing FDM prints. It lets you place several models on a build plate manually or with an automatic positioning command, then slice them, inspect the result and send jobs to a printer. Its preview can display extruder movement and support structures for an entire model, selected regions or individual layers. Printing connections include USB, TCP/IP, an SD card and Repetier-Server. The maker says the software works with almost all popular 3D FDM printers and supports up to 16 extruders at once, including different filament types and colors. Repetier-Server is included as a companion, adding browser-based printer control and the ability to print without leaving Repetier-Host running. Printer events such as paused, stopped, finished and fatal-error states can be sent to the Repetier-Informer app. Windows downloads bundle Slic3r, PrusaSlicer, CuraEngine and Skeinforge; Linux slicer setup has separate requirements. Repetier-Host runs on Windows, Linux and macOS. The maker is based in Willich, Germany, and provides documentation, a community forum and plugin-programming documentation.
