[ “3D turtle graphics ” Python library and usage example ]

English version of this paper (IJERA)

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