Today, a number of direct routes using RP processes (FDM, LOM, SLA, SLS, etc.), as well as indirect routes (RP coupled with secondary or soft-tooling processes like RTV vacuum casting) are available for rapid fabrication of tooling for sand and investment casting processes. Each route is unique in terms of geometric, material, quality and cost characteristics; no comprehensive database of their...

COST 526 project SI 4 focused on implementation of the automatic simulation-optimisation tools in several continuous casting processes. The simulation tools can be applied in several different ways to serve industry by inducing beneficial changes to process operation. These include respective better understanding of the process, better insight into the process, better influence on the process a...

In knowledge management, the act of telling stories is utilized to capture and convey knowledge. Spoken language is the basis for telling stories. Collaborative audiobased storytelling uses the act of verbally telling stories in groups. In this paper, we explore how to utilize verbally told stories for informal knowledge management. To identify the requirements for an information system that su...

UNLABELLED A simple, low-cost, versatile, and potentially scalable casting method is proposed for the fabrication of micro- and nano-thin films, herein termed as ultrasonic "substrate vibration-assisted drop casting" (SVADC). The impingement of a solution drop onto a substrate in a simple process called drop casting, usually results in spreading of the liquid solution and the formation of a non...

     Heat transfer mechanisms and the solidification process are simulated for a continuous casting machine and the geometric shape of the liquid pool is predicted considering different conditions. A heat transfer and solidification model is described for the continuous casting of steel slabs. The model has been established on the basis of the technical conditions of the slab caster in the con...

3D mili-scale channel representing simplified anatomical models of blood vessels were constructed in polidimethylsiloxane (PDMS). The objective was to obtain a sequential method to fabricate transparent PDMS models from a mold produced by rapid prototyping. For this purpose, two types of casting methods were compared, a known lost-wax casting method and a casting method using sucrose. The chann...

The solidification of metals continues to be a phenomenon of great interest to physicists, metallurgists, casting engineers and software developers. It is a non-linear transient phenomenon, posing a challenge in terms of modelling and analysis. During the solidification of a casting in a mould, the heat-transfer between the casting and the mould plays a vital role. This paper attempts to study ...
