Prusa Research XL vs Qidi Tech i-Fast
Technical comparison · Fused filament fabrication (FFF/FDM)
XL leads on the available specs (starting with price); i-Fast makes sense only for non-technical reasons (availability, support, ecosystem), or if the missing data matters in your case.

| Software notes | Compatible with PrusaSlicer (open source, with material profiles verified and maintained by Prusa Research), OrcaSlicer, and SuperSlicer, as well as any slicer that exports standard G-code. The firmware is based on Prusa Research's open-source Marlin fork, with input shaping support. Unlike Bambu Lab models, which use a partially proprietary protocol and work best with Bambu Studio, the CORE One L accepts generic G-code via USB, SD card, and PrusaConnect. The user is not locked into a single software ecosystem and can freely modify or update the firmware. | The machine comes with the proprietary Qidi Print software, a slicer based on proven open-source architectures, specifically optimized for the profiles of the technical materials supported by the printer. Users can still generate G-code using other widely adopted third-party slicers on the market, such as Ultimaker Cura, PrusaSlicer, or Simplify3D, after manual configuration of machine and extruder parameters. Although it lacks native cloud features or advanced remote connectivity for corporate fleet management, it supports direct file transfer via local Wi-Fi or USB drives, ensuring a secure offline workflow for intellectual property protection. |
