Complex Forms

A review of Drop-on-Demand additive manufacturing methods was held. A method of complex forms aluminum parts production through the application of magnetohydrodynamic pump and 5 axis manufacturing process was proposed. 5 axis 3D printer assembly was shown. A few operation modes were proposed for such 3D printer and a method for fill lines paths calculating, needed for G-code automatic generation, was established. The algorithm for calculating printhead moving trajectory in the cylindrical parts manufacture mode was shown.

Data Source

STL file is the data source of the technology. As the basis of the technology, the information of the STL file must be picked up, post-processed, and then the G code file which is tallied the PMAC rule generates as a .CFG file form in the environment of VC++. Finally, the goal of programming automation achieves after the pre-processed and post-processed of STL file. The G code downloads in the PMAC Motion Controller to control the additive manufacturing system to manufacture the bone scaffold. It realizes the automation process from the STL file of the bone to the bone scaffold in tissue engineer.

AbstractPhotopolymerization-based three-dimensional (3D) printing can enable customized manufacturing that is difficult to achieve through other traditional means. Nevertheless, it remains challenging to achieve efficient 3D printing due to the compromise between print speed and resolution. Herein, we report an efficient 3D printing approach based on the photooxidation of ketocoumarin that functions as the photosensitizer during photopolymerization, which can simultaneously deliver high print speed (5.1 cm h−1) and high print resolution (23 μm) on a common 3D printer. Mechanistically, the initiating radical and deethylated ketocoumarin are both generated upon visible light exposure, with the former giving rise to rapid photopolymerization and high print speed while the latter ensuring high print resolution by confining the light penetration. By comparison, the printed feature is hard to identify when the ketocoumarin encounters photoreduction due to the increased lateral photopolymerization. The proposed approach here provides a viable solution towards efficient additive manufacturing by controlling the photoreaction of photosensitizers during photopolymerization.
