In this work, we designed and integrated a ring electrode with the printing nozzle to achieve a self-working printer head, which can start and maintain the printing process without the involvement of the substrate. Standoff height in the EHD printing will affect printing processes and limit the height of the printed structure when the ground electrode is placed under the substrate. This paper presents an integrated ring extractor design in electrohydrodynamic (EHD) printing, which can overcome the standoff height limitation in the EHD printing process, and improve printing capability for 3D structures. for the Advancement of Material and Process Engineering.

Details of our software solutions with voxel digital designs to obtain desired part quality and correct geometries during AM, without translational digital technology (DT) to hardware technology (HT) translational factors will be discussed and presented. Careful understanding of digital design translation to printer hardware factors provide means to develop effective digital design software solutions. Printing hardware factors can be overcome by redefining voxel digital design for printing purpose only. Results indicate that success of printing from our voxel digital designs depended on the hardware factors such as print resolution in different directions of 3D builds, which affected the final geometry and material configurations. Final printed part of each voxel digital design was analyzed. To carefully understand the correlations, Vero White (Hard) material and Tango Black (Soft) material were used to define different materials regions of complex geometries, and built with a PolyJet AM system. Success of additive manufacturing relies on such digital designs being translated correctly without any artifacts by printer hardware. Demonstrative AM part configurations with complex material and geometries (using representative geometrical shapes such as circular, gear, elliptical, diamond, hexagonal, etc., as test cases), were digitally designed using voxel printing. This paper investigates print quality of designed part configurations (complex shapes, associated materials for geometrical regions) defined via voxel digital designs to understand the correlation between voxel digital designs and AM hardware. However, compatibility and correct translation between multi-material voxel digital design and 3D printing hardware is required. Voxel digital designs enable to define material at each voxel level. Voxel digital designs (similar to a pixel representing colors in a digital image) in PolyJet printing define and build composite parts with a wide range of mechanical properties, material phases and geometries. Fundamental to this is digital design that defines the associated material, complex geometries, and their translation in printer hardware during build. Wikipedia.Īdditive Manufacturing (AM) as a processing technique is now enabling tailored material and structure optimization due to its capability for forming complex materials and geometries, material phases that can be at resolution levels of hundreds of microns. The graduate school offers 104 master's degrees, 61 doctoral degrees, and a Doctor of Veterinary Medicine. NC State has historical strengths in engineering, agriculture, life science, textiles and design and now offers 106 bachelor's degrees. Today, NC State has an enrollment of more than 34,000 students, making it the largest university in the Carolinas. The university forms one of the corners of the Research Triangle together with Duke University in Durham and The University of North Carolina at Chapel Hill.The North Carolina General Assembly founded the North Carolina College of Agriculture and Mechanic Arts, now NC State, on March 7, 1887, as a land-grant college. Commonly known as NC State or simply State, the university is part of the University of North Carolina system and is a land, sea, and space grant institution. North Carolina State University, officially North Carolina State University at Raleigh, is a public, coeducational, research university located in Raleigh, North Carolina, United States.
