Rotational 3D Printing of Sensor Devices using Reactive Ink Chemistries
(2008)This paper charts progress in three key areas of a project supported by both UK government and UK industry to manufacture novel sensor devices using rotary 3D printing technology and innovative ink chemistries; (1) the ... -
Laser Micro Sintering – A Quality Leap through Improvement of Powder Packing
(2008-09-10)Laser micro sintering, a modification of selective laser sintering for freeform fabrication of micro-parts, was continuously upgraded since its first application. Poor density of the powder layers has been a persisting ... -
Processing Parameters for Selective Laser Melting (SLM) of Gold
(2008-09-10)Research into laser processing of different metals has enabled Solid Freeform Fabrication (SFF) processes to produce parts for a wide variety of applications. However, less focus has been made on the processing of precious ... -
Impact Absorbent Rapid Manufactured Structures (IARMS)
(2008)Rapid Manufacturing (RM) is increasingly becoming a viable manufacturing process due to dramatic advantages that it facilitates in the area of design complexity. Through the exploration of the design freedom afforded by ... -
A New Layer Casting System for Ceramic Laser Rapid Prototyping Apparatus
(2008-09-10)In the existing Ceramic Laser Fusion system, slurry is fed on the high temperature surface of the green part; therefore, a part of water infiltrates into the green block and vaporizes before the process of layer casting. ... -
Printing High Viscosity Fluids using Ultrasonic Droplet Generation
(2008-09-10)A new printing technology based on ultrasonic actuation (~1 MHz) is presented that has the potential to print high viscosity fluids. In this paper, we describe the print-head’s operating principles and construction. ... -
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 ... -
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, ... -
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 ... -
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 ... -
Selective Laser Sintering and Post Processing of Fully Ferrous Components
(2008-09-10)Commercially available steel for indirect SLS (LaserFormtm A6 tool steel) is normally post-process infiltrated with a copper-based material. While such parts have high thermal conductivity necessary for short- and ... -
Tunable Digital Material Properties of 3D Voxel Printers
(2008-09-10)Digital materials are composed of many discrete voxels placed in a massively parallel layer deposition process, as opposed to continuous (analog) deposition techniques. We explore the material properties attainable using ... -
Product Focused Freeform Fabrication Education
(2008-09-10)Presented in this paper is our experience of teaching freeform fabrication to students at the Missouri University of Science and Technology, and to high school students and teachers. The emphasis of the curriculum is ... -
Using Literature Reviews as a Learning Tool for Solid Freeform Fabrication
(2008)Over the past six years, students involved in the “Non-Traditional & Additive Manufacturing” course at Utah State University have been assigned an in-depth literature review as one their course projects. This literature ... -
Selective Laser Melting of Inconel 625 using Pulse Shaping
(2008-09-10)Pulse shaping is a technique used to temporally distribute energy within a single laser pulse. This allows the user to have an added degree of control over the heat delivered to the laser material interaction zone. Pulses ... -
Wear of SLS Materials under Plastic and Elastic Contact Conditions
(2008)Sliding wear behaviour of two SLS materials: LaserForm and DirectSteel has been investigated using Fretting tests, Pin-on-disc tests and microfretting tests. Wear test conditions were determined by calculating Hertzian ... -
