Repetier is a free 3D slicer that lets you easily import, rotate, scale, and adjust your models before printing. It’s part of a larger suite, including Repetier-Server, which allows for remote printing and monitoring, similar to OctoPrint. By installing Repetier-Server on a Raspberry Pi, you can manage your prints remotely from a laptop or smartphone.
Though not as widely used as Cura, Repetier is still a solid free option, offering printing via USB, SD card, or directly to your printer. For manufacturers, Repetier also provides a customizable version with branded options and tailored print and filament settings to streamline customer support.
