Selective Infrared Sintering of Polymeric Powders using Radiant IR Heating & Ink Jet Printing
(2006-09-14)Established methods of rapid prototyping by sintering polymeric powders have predominantly focused on the use of lasers to selectively heat the polymeric particles together to form fused layers. Although effective, this ... -
Selective Laser Melting of Biocompatible Metals for Rapid Manufacturing of Medical Parts
(2006-09-14)In recent years, digitizing and automation have gained an important place in fabrication of medical parts. Rapid Manufacturing could be very suitable for medical applications due to their complex geometry, low volume and ... -
Selective Laser Sintering of Passive Dynamic Ankle-Foot Orthoses
(2006)Passive dynamic ankle-foot orthoses (AFO’s) are used to improve gait performance in those with various neuromuscular disorders. An important design characteristic of passive dynamic AFOs is the storage and release of ... -
SLS Fabrication of Highly Porous Model Including Fine Flow Channel Network Aiming at Regeneration of Highly Metabolic Organs
(2006-09-14)Fabrication of very porous scaffold for regeneration of highly metabolic organs is reported. Polycaprolactone (PCL) powder was mixed with fine salt grains as filler and SLS processed to develop a model including fine ... -
Structurally Embedded Electrical Systems Using Ultrasonic Consolidation (UC)
(2006)Current research has demonstrated the use of Ultrasonic Consolidation (UC) to embed several USB-based sensors into aluminum, and is working toward embedding suites of sensors, heaters and other devices, connected via USB ... -
A Study of Static and Dynamic Mechanical Behavior of the Substrate in Ultrasonic Consolidation
(2006-09-14)A new 2-D FEM model is developed for a fundamental study of the time dependent mechanical behavior of the substrate in ultrasonic consolidation. The simulation shows that for a given vibration condition, the amplitude ... -
Support-Free Infiltration of Selective Laser Sintered (SLS) Silicon Carbide Preforms
(2006-09-14)Non-metallic objects are often difficult to manufacture due to high melting temperatures, poor sinterability, limited ductility, and difficulty in machining. Freeform fabrication techniques coupled with liquid infiltration ... -
Transferring Unit Cell Based Tissue Scaffold Design to Solid Freeform Fabrication
(2006)Designing for the freeform fabrication of heterogeneous tissue scaffold is always a challenge in Computer Aided Tissue Engineering. The difficulties stem from two major sources: 1) limitations in current CAD systems to ... -
Transient Physical Effects in Electron Beam Sintering
(2006-09-14)The extensive use of the electron beam in manufacturing processes like welding or perforating revealed the high potentials for also using it for solid freeform fabrication. First approaches like feeding wire into a melt ... -
UV-Photolithography Fabrication of Poly-Ethylene Glycol Hydrogels Encapsulated with Hepatocytes
(2006)The development of biomanufacturing technologies particularly, layered manufacturing has advanced cell encapsulation processes in an effort to mimic the cellular microenvironment for invitro studies. This paper illustrates ...
