  • Challenges in Three-Dimensional Printing of High ...

    2018-5-9 · Limited experiments using laser powder bed fusion process to additively manufacture of pure copper on steel substrate (referred to as “CuonSt” in this paper) were performed, and these early trials showed ∼18% porosity in the deposited material, which appeared to be mostly due to “lack of fusion” porosity defects (Fig. 16, right). A model was developed for the powder bed fusion single track melt pool to guide the copper on copper …

  • Three-dimensional printing of stem cell-laden

    2012-11-21 · Here, we hypothesise that cell-laden hydrogels can be printed when submerged in perfluorotributylamine (C 12 F 27 N), a hydrophobic high-density fluid, and that these cells placed within three-dimensional constructs remain viable allowing for cell proliferation and production of extracellular matrix. Human mesenchymal stem cells and MG-63 cells were encapsulated into agarose hydrogels, and subsequently printed in high aspect ratio in three dimensional …

    A mode of vibration is a characteristic pattern or shape in which a mechanical system will vibrate. Most systems have many modes of vibration, and it is the task of modal analysis to determine these mode shapes. The actual vibration of a structure is always a combination or mixture of all the vibration modes.
