Three-Dimensional Digital-Mold Modeling and Sand-Printing for Replication of Bronze Mirror

THREE DIMENSIONAL MODELING OF TURBULENT FLOW WITH FREE SURFACE IN MOLD FILLING

In the present study a Finite Difference Method has been developed to model the transient incompressible turbulent free surface fluid flow. A single fluid has been selected for modeling of mold filling and The SOLA VOF 3D technique was modified to increase the accuracy of simulation of filling phenomena for shape castings. For modeling the turbulence phenomena k-e standard model was used. In or...

A novel three-dimensional printing of electroconductive scaffolds for bone cancer therapy application

Objective(s): Tissue engineering aims to achieve a tissue, which has highly interconnected porous microstructure concurrent with appropriate mechanical and biological properties. Materials and Methods: Therefore, the microstructure scaffolds are of great importance in this field. In the present study, an electroconductive poly-lactic acid (EC-PLA) filament used to fabricate a porous bone ...

Robotic positioning device for three-dimensional printing

Additive manufacturing brings a variety of new possibilities to the construction industry, extending the capabilities of existing fabrication methods whilst also creating new possibilities. Currently three-dimensional printing is used to produce small-scale objects; largescale three-dimensional printing is difficult due to the size of positioning devices and machine elements. Presently fixed Co...

In-lab three-dimensional printing

The development of the microscope in 1590 by Zacharias Janssenby and Hans Lippershey gave the world a new way of visualizing details of morphogenesis and development. More recent improvements in this technology including confocal microscopy, scanning electron microscopy (SEM) and optical projection tomography (OPT) have enhanced the quality of the resultant image. These technologies also allow ...
