Rapid Prototyping - Rapid Tooling - Rapid Manufacturing

An adaptive process planning approach of rapid prototyping and manufacturing

This paper presents an adaptive approach to improve the process planning of Rapid Prototyping/ Manufacturing (RP/M) for complex product models such as biomedical models. Non-Uniform Rational B-Spline (NURBS)-based curves were introduced to represent the boundary contours of the sliced layers in RP/M to maintain the geometrical accuracy of the original models. A mixed tool-path generation algori...

Rapid Manufacturing with Fdm in Jig & Fixture Construction

The weight of a device is an ergonomic criterion as well. Devices that are carried and operated by people may not exceed a weight of 5 kg (11 lbs.). Previously, this was achieved by using lowdensity materials, such as aluminum or polyamide. An additional weight reduction, however, can be obtained through the use of ABS plastics and the FDM process. The density differences of ABS and polyamide d...

Rapid Manufacturing in Biomedical Materials: Using Subtractive Rapid Prototyping for Bone Replacement

Reviewed, accepted September 10, 2008 This paper presents methods for the rapid manufacturing of replacement bone fragments using a Subtractive Rapid Prototyping process called CNC-RP. The geometry of segmental defects in bone, resulting from traumatic injury or cancerous tumor resection, can be reverse-engineered working from medical images (such as CT scans), and then accurate defect fillers ...
