“3D Turtle Graphics” by using a 3D Printer

When creating shapes by using a 3D printer, usually, a static (declarative) model designed by using a 3D CAD\ud system is translated to a CAM program and it is sent to the printer. However, widely-used FDM-type 3D printers\ud input a dynamical (procedural) program that describes control of motions of the print head and extrusion of the\ud filament. If the program is expressed by using a programming language or a library in a straight manner, solids\ud can be created by a method similar to turtle graphics. An open-source library that enables “turtle 3D printing”\ud method was described by Python and tested. Although this method currently has a problem that it cannot print in\ud the air; however, if this problem is solved by an appropriate method, shapes drawn by 3D turtle graphics freely\ud can be embodied by this method
