Non Linear FDM Toolpath

Image
 This is the base pattern I designed in Rhino — a series of overlapping curves inspired by organic repetition. It started from a simple idea, but seeing it build up visually was exciting. This became the foundation for the whole piece. I used Grasshopper to control all the variables for generating the toolpath — here you can see one of the sliders I created to set the Z clearance. This helped define the height between each pass of the print head. This is the simulated toolpath — basically what the 3D printer will follow. It was interesting to see how clean or messy this could get depending on how the curves overlapped or how I sorted the paths. I generated the G-code directly in Grasshopper. It includes commands for setting units, homing the printer, and each extrusion point. Writing it this way gave me full control over how the printer interprets my design. The first layers being printed on the Prusa. This moment always feels satisfying — seeing the digital sketch actually come to...

Drawing Part One and Two

Image
Part one: This is my starting point in  Rhino , where I created a  2D composition  using geometric and organic shapes. The design includes circles, angular structures, and fluid forms, which will later be processed in  Grasshopper  for pattern generation and extrusion. Using  Grasshopper , I applied  hatch fills, scribble textures, and contour lines  to specific regions of the composition. These different textures will add complexity when the design is  extruded and 3D printed .      This step focuses on  optimizing toolpaths  for 3D printing. On the left side, you can see the  Rhino viewport , where the generated  contour and pattern lines  have been converted into a dense toolpath. The red dots and lines represent  print movement paths , ensuring controlled material deposition. On the right side, in  Grasshopper , I have set up parameters to refine the  printing resolution and efficienc...

CNC Experience

Image
 CNC Machine Drawing     I started this project by sketching a series of organic shapes directly in Rhino. My goal was to create a flowing, biomorphic composition that felt almost like a topographic map or a cellular structure.  Then I jumped into Grasshopper to generate the toolpaths. This part involved tweaking settings like Z-clearance, XY resolution, and feed rate. I also used logic to sort curves and skip ones that were too short to make a clean drawing and streamed the gcode. Finally, I exported the toolpath into G-code using Grasshopper. This text file tells the CNC machine exactly where to move and when to lift or lower the pen. Once this was ready , I took it to the CNC machine to bring the design to life on paper. Once the G-code was ready, I moved over to the CNC computer. I used AvidCNC’s interface to import the toolpath and verify that the drawing aligned correctly with the paper dimensions. With the machine zeroed and the pen lightly touching the paper,...
