“…At this point, the user is provided with additional options and functionality provided by the integration of some of the features originally developed as part of the Light Animator software package within the Design23DPrint software package. Light Animator was designed to allow a user to manipulate each of the mirrors of the DMD in groups or individually, which translates into having pixel-by-pixel control over a two-dimensional image [2]. This capability was ported into Design23DPrint from Light Animator to allow the user to directly edit, pixel-by-pixel, the content of each layer of the object that is to be printed.…”

As 3D printer technology has rapidly developed and penetrated into a wide range of applications, several methods for creating 3D objects have been explored and developed. One such method utilizes UV curing of special resins, where the patterning of each layer of the 3D object is determined by a digital micromirror device (DMD) controlled by a digital light processing (DLP) system. This method possesses important advantages over other methods in terms of variable object composition, high spatial resolution, and reduced build times, but usually requires specialized knowledge to program and control the DMD and other printer systems. Not all potential users of 3D printers will be able or willing to acquire this knowledge in order to take full advantage of all that 3D printing has to offer in their ideas or applications. new software package called Design23DPrint has been developed that provides a user-friendly and intuitive interface for importing, manipulating, and editing 3D objects and has the ability to be readily interfaced with many different DLP and printer control systems. Both layer creation and the positioning of supports can be automated or be manually controlled. Integration of Design23DPrint with existing software packages for DMD control allows the user to edit layers on a pixel-by-pixel basis. The software was integrated with a new 3D printer design developed by Texas Instruments to demonstrate the capabilities of the software to control the printing process and to interface with resident control systems.
