Introduction: Week 4: Slicer

I tried Option 3, which is experimenting with existing slicing plugins for Grasshopper for my Week 4 assignment. I used Droid ( for generating GCode in Grasshopper to print Koch's Snowflake.

Step 1: Koch Snowflake

I modified the Koch snowflake code from
I've started with a small snowflake, moved the position to fit inside the bed, and increased the size.

Step 2: Printing (trial 1)

What took me long time was to generate mesh for the input to slicer. At first, I tried using Delaney triangulation and the result didn't turn out nice and the outline of snowflake didn't print well.

Step 3: Printing (trial 2)

Finally I tried using 'Mesh Brep' component to the extruded surface. Then it worked out well :)
