Analysis of Droplet Train/Moving Substrate Interactions in Ink-Jetting Processes
(2008-09-10)Ink-jetting technology has been applied to several processes in solid free-form fabrication (SFF) wherein droplets impinge onto a substrate to deposit the build material. Droplet impact behaviour on a surface has been ... -
The Characteristics and Applications of Ceramic Laser Fusion and Ceramic Laser Sintering
(2008-09-10)The aim of present study is to investigate the possible application of the ceramic parts which are fabricated with the process of Ceramic Laser Fusion or Ceramic Laser Sintering. The experimental results reveal: (1) CLF ... -
A Comparison of Synthesis Methods for Cellular Structures with Application to Additive Manufacturing
(2008-09-10)Cellular material structures, such as honeycombs and lattice structures, have been engineered at the mesoscale for high performance and multifunctional capabilities. We desire efficient algorithms for searching the large, ... -
Developing printable content: A repository for printable teaching models
(2008-09-10)Alongside the development of RP technology, there is an increasing need to develop and share printable content. Like digital photography and digital music, content drives technology as much as technology drives content. ... -
Development of an Additive Layer Manufacturing (ALM) Selection Tool for Direct Manufacture of Products
(2008-09-10)Advancements in Additive Layer Manufacturing (ALM) technology and a broader knowledge base of process and material capabilities make ALM increasingly, a more valid manufacturing option. Small creative industry and ... -

Effect of path strategies on metallic parts manufactured by additive process
(2008-09-10)Metal deposition processing is well known for cladding by laser or welding process. Nevertheless, these systems are not optimized for direct manufacturing. One of the main lock is the need of dedicated CAD/CAM systems ... -
Effects of Degree of Particle Melt and Crystallinity in SLS Nylon-12 Parts
(2008-09-10)Differential Scanning Calorimetry (DSC) traces for SLS Nylon-12 parts display two distinct melt peaks, which have been related to the presence of both melted and crystallised regions, and un-melted particle cores within ... -
Efficient concurrent toolpath planning for multi-material layered manufacturing
(2008-09-10)This paper proposes an algorithm for planning efficient concurrent toolpaths to reduce the build-time of fabricating multi-material prototypes by layered manufacturing. The algorithm first sorts and partitions slice ... -
An Experimental Determination of Optimum Foil Joint Conditions for Structural Parts Fabricated by Ultrasonic Consolidation
(2008-09-10)This paper describes an investigation of the optimum conditions necessary to eliminate defects at foil joints in parts fabricated by ultrasonic consolidation. Tensile test specimens were fabricated with different foil ... -
Fabrication of Complex 3D Micro-Scale Scaffolds and Drug Delivery Devices using Dynamic Mask Projection Microstereolithography
(University of Texas at Austin, 2008-09-10)Microstereolithography (μSL) technology can fabricate three-dimensional (3D) tissue engineered scaffolds with controlled biochemical and mechanical micro-architectures. A μSL system for tissue engineering was developed ... -
Fabrication of Electrically Conductive, Fluid Impermeable Direct Methanol Fuel Cell (DMFC) Graphite Bipolar Plates by Indirect Selective Laser Sintering (SLS)
(2008-09-10)Graphite bipolar plates are highly desirable due to their properties of high electrical conductivity and low weight but are associated with prohibitive machining costs arising from poor mechanical properties. Bipolar ... -
Fabrication of Embedded Horizontal Micro-Channels Using Line-Scan Stereolithogrpahy
(University of Texas at Austin, 2008-09-10)In an effort to directly and rapidly manufacture micro-fluidic devices with embedded horizontal micro-channels on the order of tens of microns, a method was developed for using current commercially available line-scan ... -
A Film Fabrication Process on Transparent Substrate using Mask Projection Micro-Stereolithography
(2008-09-10)In this study, a Mask Projection Micro-Stereolithography (MPµSLA) process with the ability to cure a film of various thicknesses on transparent substrates is presented. Incident radiation, patterned by a dynamic mask, ... -
