Novel Cold Crucible Ultrasonic Atomization Powder Production Method for 3D Printing

Hybrid Gas Atomization for Powder Production

Towards an Expert System for Powder Production Processes : (I) the Atomization Process

The practical definition for the expert system, as a system simulating the expert methods and knowledge in dealing with or manipulating special tasks is presented. The application of such a system in powder technology is attempted. The main features of the proposed system design are documented. It constitutes, actually, another part of an effort towards building an expert system for powder tech...

Method for Procedural 3D Printing Using a Python Library

When manufacturing or 3D-printing a product using a computer, a program that procedurally controls manufacturing machines or 3D printers is required. G-code is widely used for this purpose. G-code was developed for controlling subtractive manufacturing (cutting work), and designers have historically written programs in G-code, but, in recently developed environments, the designer describes a de...

Analysis of Size Correlations for Microdroplets Produced by Ultrasonic Atomization

Microencapsulation techniques are widely applied in the field of pharmaceutical production to control drugs release in time and in physiological environments. Ultrasonic-assisted atomization is a new technique to produce microencapsulated systems by a mechanical approach. Interest in this technique is due to the advantages evidenceable (low level of mechanical stress in materials, reduced energ...

A Novel Method for Ultrasonic Evaluation of Horizontal Defects Using Time-of-Flight Diffraction

Time-of-flight diffraction method (ToFD) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. Although ToFD can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. In this paper, a new ToFD method for evaluating horizontal planar defects is presented. The finite...
