What Repetier-Host is
Repetier-Host is 3D printer software for arranging models, slicing, previewing, and printing. It runs on Windows, Linux, and macOS, and the maker says it works with almost all popular 3D FDM printers. Users can position multiple models manually or use automatic placement to fit them on the build plate. After slicing, previews can show extruder movements and support structures across the model, selected regions, or individual layers. Printing connections include USB, TCP/IP, SD card, and Repetier-Server, and the software supports up to 16 extruders with different filament types and colors. Repetier-Server is included as a companion and can provide browser-based printer control and printing without Repetier-Host running. Printer status events can be sent to the Repetier-Informer app. The Windows bundle includes Slic3r, PrusaSlicer, CuraEngine, and Skeinforge; Linux slicer setup has separate requirements. The free download is listed as free. Paid customization options include Additional customization at €599 a year and Custom Repetier-Host for Windows at €2,199 a year, billed excluding VAT.
