This article proposes a method for assessing the competitiveness of building 3D printers based on comparison their technical and technological characteristics economic parameters. The methodology implements an integrated approach that takes into account large number parameters different nature use relative indicators. calculation design printers, manufacturability printing process, printed obje...
We have developed a method for the three-dimensional (3D) printing of continuous fiber-reinforced thermoplastics based on fused-deposition modeling. The technique enables direct 3D fabrication without the use of molds and may become the standard next-generation composite fabrication methodology. A thermoplastic filament and continuous fibers were separately supplied to the 3D printer and the fi...
This paper describes a novel approach to making 3D replicas of nearly flat objects using a flatbed scanner and a 3D printer. The surface reconstruction is based on the fact that the light in a flatbed scanner shines under a given constant angle and the CCD sensor records different intensities depending on the angle between a local normal vector of a micro-facet and the vector towards the light ...
Introduction: Geometric distortion is a major shortcoming of magnetic resonance imaging (MRI), which has an important influence on the accuracy of volumetric measurements, an important parameter in neurology and oncology. Our goal is to design and construct a new three- dimensional phantom using a 3D printer in order to measure geometric distortion and its reproducibility in...
A fluidic device constructed with a 3D-printer can be used to investigate stored blood components with subsequent high-throughput calibration and readout with a standard plate reader.
