Ceramic Materials Improve Spacecraft Insulators Authors: Capt. Steven G. Steel and Tim Anderl. Web Article, July, 2005. The authors are with the US Air Force's Materials and Manufacturing Directorate. It describes the use of LOM to make ceramic Hall thrusters for satellites. Hall thrusters are low thrust propulsion devices used for making adjustments to keep satellites in the correct orbit and for attitude changes to allow for proper alignment of telescopes and antennas.
Repairing turbines with metal beads. Author: anon. Industrial Laser Solutions, web ed., May, 2005. The Fraunhofer Institute (Germany) describes the repair of gas-turbine blisks, which can cost as much as $70,000 to replace, with direct metal deposition technology.
Rapid prototyping evolves into custom manufacturing. Author: Kathy Kincaide. Laser Focus World, May, 2005. A good overview of existing applications and the incremental improvements that are turning RP into RM.
Laser cladding makes the grade. Authors: Ron Boyer, Richard Martukanitz. Industrial Laser Solutions, November, 2004. Alvord-Polk uses a laser-based direct metal deposition process to turn blanks into high-speed cutting tools quickly, while minimizing wasted metal and improving metallurgy.
Rapid Manufacturing Ramps Up. Author: Louise Elliott. Desktop Engineering, November 2004. The evolution of materials and technology is permitting machines that formerly were used for RP to be used for limited quantity manufacturing. Mainly discusses FDM and 3DP technologies.
Metal deposition repairs critical parts. Author: AM Staff. American Machinist, October 1, 2004. A brief article about using Optomec's LENS (TM) process to Extending the life of aging aircraft combat vehicles, artillery, and small arms for the Department of Defense.
Direct Metal On the Rise. Author: Todd Grimm. Manufacturing Engineering, Oct. 2004. A survey of current applications for direct metal processes from Optomec, Trumpf, Solidica and Accufusion.
Direct-write laser processing creates tiny electrochemical systems. Authors: Craig Arnold, Thomas Sutto, Heungsoo Kim, Alberto Pique. Laser Focus World, May, 2004. An extensive article about using laser-direct write technologies to fabricate tiny batteries for MMD's.
The Biology of Direct Writing and Rapid Prototyping. Author: Adrian Bowyer, University of Bath (UK). Web article. Adrian Bowyer discusses a way of applying RP technology that he considers might be a more economic than industrial revolution. The provocative discussion centers around machines that can self-replicate and lead to exponential changes. "Rapid prototyping is often said to be the start of a new industrial revolution; see, for example, sources as diverse as the recent New Scientist article listed here and the car production scene in Spielberg's 'Minority Report'. Such talk of revolution may well be hype, of course." Or maybe not...
Rapid Manufacturing. Author: Carol Y. Wang. Cambridge Scientific Abstracts, (Web article), Sept., 2002. Several technologies collectively known as Rapid Manufacturing (RM) have been developed to shorten the design and production cycle, and promise torevolutionize many traditional manufacturing procedures. The article is a fairly thorough review of the technology and its capabilities.
Rapid evolution: New materials and process improvements are stretching the boundaries of prototyping techniques. Author: John DeGaspari. Mechanical Engineering, March 2002. The article describes how rapid prototyping is moving from the generation of concept models to final production applications. The effect of materials developments on the field is discussed, as well as the limitations of various technologies.
Will RP Stand For Rapid Production Someday? Author John Connolly. Time Compression Technologies, March, 2002. Well, actually some companies are already doing it. Mass customization manufacturing allows manufacturers to realize the benefits of RP. A manufacturer can design and perfect the product by building iterations, then make changes to that same data file to produce a customized part.
Multilayer MEMs. (News & Notes). Author: Harry Hutchinson. Mechanical Engineering, Feb 2002. Microfabrica's (formerly MEMGen Corp.) introduction of a layered fabrication technique for small parts, based on electronic fabrication (EFAB), developed at the University of Southern California is described. Layers can be between 2 and 15 microns thick and the technology utilizes masks generated from CAD files.
