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.
