FELIXbuilder review
A focused slicer for preparing FELIX jobs, with editable profiles and dual-nozzle calibration.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
FELIXbuilder is desktop software for preparing and slicing printable 3D objects for FELIXprinters' FDM printers. It is aimed at FELIX printer owners who want model preparation, slicing, and job submission in one workflow, particularly those handling dual-nozzle jobs. It runs on Mac and Windows and supports importing STL files, transforming or duplicating parts, and selecting FELIX printer models and profiles.
Profile editing is a notable part of the workflow: settings cover slicing, materials, build strategies, and supports. Users can preview slices and toolpaths before generating G-code or submitting a job to a connected printer. The software also includes build-platform and dual-nozzle calibration. That combination suits users who need control over FELIX-specific preparation and calibration; it is less suitable for shops that need a slicer spanning different printer brands, since the listed printer selection is limited to FELIX models.
FELIXbuilder is sold on a contact-sales basis, and there is no free plan. A historical vendor page describes one-year and lifetime licenses, while a printer manual mentions a bundled free one-year license; neither establishes a current standalone price. Buyers should ask FELIXprinters about current licensing and fit before committing. Choose FELIXbuilder if your workflow centers on FELIX hardware and its profiles. If broad printer compatibility is a priority, a slicer with support beyond FELIX models is a better direction.
