Putting Version 7.1 Of The Direct Granules FDM Extruder Through Its Paces No comments by: Maya Posch May 23, 2026 Title: Copy Short Link: Copy Whether you’re using granules or filament, FDM printing relies heavily on a consistent flowrate of the extruder. This is also the challenge with [HomoFaciens]’s direct granule extruder. Version 7.1 here refines some parameters before being put through a number of printing tests to see how close it comes to something you’d want to use for production. There’s also an accompanying blog post, on which the project files can be found for those who are playing along at home.
