Extruder-Turtle: A Library for 3D Printing Delicate, Textured, and Flexible Objects

ABSTRACT This paper introduces , an open-source Turtle Geometry library for 3D printing, which generates G-CODE based on the path traveled by a LOGO-inspired Turtle. We describe the functionality of our library and demonstrate how it provides an intuitive and accessible way to create objects with a range of interesting properties, using Fused Deposition Modeling (FDM) 3D printers. We also present a collection of examples–including replications of previous research as well as original investigations–to demonstrate the power and flexibility of our library and this general approach. Our examples include 3D printed textiles, textured surfaces, and delicate string-art sculptures, along with traditional Turtle Geometry forms.
