Tracer testing has been used to obtain hydraulic properties in a reservoir system and may help characterize the fracture networks inside the reservoir. Numerous studies at various scales have shown that the distribution of many fracture properties (i.e., length, displacement) follows a power law scaling with some cutoffs. Fractal dimension is useful to evaluate the geometric characteristics of ...
Objective: This study was aimed to determine the biocompatibility of gelatin-alginate scaffolds with 3D bio-printer and the mice bone marrow mesenchymal stem cells (BMSCs), and the histocompatibility during skin wound healing. Methods: BMSCs was separated and cultured using pan-marrow attachment method and the third generation combined with gelatin-alginate was added to the 3D printer for the p...
We have developed a system for the rapid fabrication of low cost 3D devices and systems in the laboratory with micro-scale features yet cm-scale objects. Our system is inspired by maskless lithography, where a digital micromirror device (DMD) is used to project patterns with resolution up to 10 µm onto a layer of photoresist. Large area objects can be fabricated by stitching projected images ov...
The process of research and refinement Fused Deposition Modeling 3D Printer, surely contains many variables parameters with the aim generating a object results level accuracy approaching its original design can be applied as expected design. In addition to effect printer type on FDM method, filament material used filler print objects certainly has different mechanical physical characteristics, ...
