Salad Slicer is a specialized Grasshopper plugin designed for 3D concrete printing that generates continuous toolpaths and G-code. Engineered for additive manufacturing, this Grasshopper definition facilitates the complex task of path planning for extrusion-based fabrication. It translates geometric models into sequential print paths, allowing users to define layer heights, print speeds, and extrusion rates directly within the Rhino environment. The script is highly technical, focusing on the continuity of the print head movement to prevent material discontinuities during the construction of concrete elements. It acts as a bridge between digital modeling and robotic hardware, ensuring that complex architectural geometries can be realized through automated, large-scale 3D printing workflows.

The download is a 133 KB file containing .ZIP files.

To integrate this definition, users load the script into the Grasshopper canvas and reference their target mesh or surface geometry. The plugin processes the input to generate the required toolpath curves. Once the path is optimized, the component exports the data as G-code, which is then sent to the controller of the concrete printing system. Users must ensure that their printer's kinematic configuration is compatible with the output format before initiating the fabrication sequence.

This tool is essential for architectural practices and research groups exploring large-scale additive manufacturing and robotic construction. It is primarily used in the development of experimental concrete structures, custom facade panels, and rapid prototyping of building components. Professionals working on research-led design projects will find this useful for automating the transition from computational geometry to physical reality. It is frequently deployed alongside robotic arm controllers and specialized cementitious material delivery systems in both laboratory settings and industrial fabrication facilities.
