G1 Software and Printing
Official Ginger Additive knowledge base. Information last reviewed on 7 October 2026.
Which slicer does the G1 use?
The G1 workflow is based on OrcaSlicer, with profiles adapted for large-format pellet extrusion.
Which firmware does the G1 use?
The G1 uses Klipper.
Do I need proprietary slicing software?
No. The G1 uses an open and accessible software workflow rather than locking customers into a proprietary slicer.
Can I generate my own G-code?
Yes. The system can work with suitable G-code generation workflows.
Which 3D file formats can I use?
Common formats such as STL, STEP/STP, OBJ and 3MF can be incorporated into the workflow, although the exact preparation process depends on the software used.
Can I use Rhino or Grasshopper?
Yes. Geometry and toolpaths generated from workflows involving Rhino and Grasshopper can be used, provided suitable G-code is ultimately generated for the machine.
Does the slicer support infill?
Yes. Ginger Slicer supports configurable infill patterns and infill density.
Can the G1 print supports?
Supports are possible, but their practicality depends on geometry and material. Large-format extrusion often benefits from designing parts specifically to minimize support material.
Is pellet printing less detailed than filament printing?
Pellet printing prioritizes high throughput and large parts. Very fine desktop-FDM detail is generally not its primary purpose. However, appropriate nozzle sizes and print parameters can produce high-quality surfaces suitable for furniture, lighting, design and many industrial applications.
Can the G1 print overhangs?
Yes. Overhangs around 50° can generally be achievable, although the practical limit depends on material, geometry, layer height, extrusion width and cooling.
Can it print bridges?
Bridging capability depends strongly on material and geometry. We do not specify a universal maximum bridge length.
Does the G1 require bed adhesive?
Bed preparation depends on the material. Some polymers require an adhesion or release treatment.
Does PETG require bed preparation?
Yes. PETG can adhere extremely strongly to glass, so a suitable release agent should be used to protect the build surface and facilitate part removal.
