the fabrication of complex-shaped parts out of (wt %) co-28cr-6mo alloy by three-dimensional printing (3dp) was studied using two grades of the alloy with average particle sizes of 20 and 75 μm. to produce sound specimens, 3dp processing parameters were tuned. the sintering behavior of the powders was characterized by the dilatometric analysis. batch sintering in argon atmosphere at 1280 °c for...

The concept of Rapid Manufacturing (RM) is emerging from the so-called Rapid Prototyping technologies where additive rather than subtractive techniques will be used to make parts or even completed assemblies. As no tooling is required, one of the main benefits of RM will be the ability to make cost-effective custom products that could all be entirely individualised to a particular consumer or u...

Layered manufacturing (LM) or rapid prototyping is a process in which a part is produced using layer-by-layer addition of the material. In LM, slicing of the CAD model of a part to be produced is one of the important steps. Slicing of CAD model with a very small slice thickness leads to large build time. At the same time if large slice thickness is chosen, the surface Žnish is very bad due to s...

This paper discusses the informational requirements of layered manufacturing (LM). The most common industrial use of LM today is for rapid prototyping, but we take a wider view of it as a flexible fabrication technology. Its use in building functional metallic parts under computer control has already been demonstrated in the research context. Commercial LM machines for building production parts...
