Multi-layer Halftoning for Poly-jet 3D Printing

Jet-based 3d Printing of Biological Constructs

Organ printing is the layer-by-layer bottom-up fabrication of complex cellular organization of native tissues or organs by bioprinting multiple cell types and other biomaterials at designated positions. The rising success rate of transplants has resulted in a critical need for more tissues and organs. Approximately 95,000 people are on the waiting list for new organs in the U.S. alone, and some...

Multilevel halftoning applied to achromatic inks in multi-channel printing

3D Halftoning

3D printing is becoming increasingly popular around the world today. By utilizing 3D printing technology, customized products can be manufactured much more quickly and efficiently with much less cost. However, 3D printing still suffers from low quality surface reproduction compared with 2D printing. One effective approach to improve it is to develop an advanced halftoning algorithm for 3D print...

Organ printing: computer-aided jet-based 3D tissue engineering.

Tissue engineering technology promises to solve the organ transplantation crisis. However, assembly of vascularized 3D soft organs remains a big challenge. Organ printing, which we define as computer-aided, jet-based 3D tissue-engineering of living human organs, offers a possible solution. Organ printing involves three sequential steps: pre-processing or development of "blueprints" for organs; ...

Permanence and Color Stability in 3D Ink-jet Printing

In recent years, the possibility of color three-dimensional printing has been introduced. The process described in this work is by ZCorporation, and is currently the only process enabling full color printing. The basic materials are in the shape of powder and binders, clear and/or colored. In order to obtain final mechanical and surface properties, 3D prints are almost always postprocessed with...
