In this paper, we describe a teaching and research experiment which has beentaking place in two Faculties of Architecture in Belgium for the last five years. This experiment focuses ondiscovering and exploring new design issues based on digital concepts and aims identifying andcharacterizing the design praxis shifts (mutations) by the digital culture integration. More precisely, thisexperiment aims at having students discovering and exploring design issues in the first stage of virtual(parametric) model elaboration including fabrication possibilities within its own internal logic.

As teachers in a Belgian Faculty of Architecture, we present a learning-by-doing workshop experience.It aims to achieve on one hand the design and the building of a prototype of kinetic and adaptive architectural skin and on the other hand to develop a design frame.Using an advanced educational process as a guide line, based on designing / prototyping we discuss what accurate knowledges and specific skills are needed to perform a usable and relevant modeling associated to an appropriate production method.We demonstrate how incorporate complexity into the design space, and develop an accurate help for creative thinking, especially to manage a kinetic architectural object.

Sketching and prototyping of design concepts have long been valued as tools to support productive early stage design. This study investigates previous findings about the use and timing of use of such design tools. This study considers such tools in the context of team design projects. General trends and statistically significant results about “sketchstorming” and prototyping suggest that, in certain constrained contexts, the focus should be on the quality of information rather than on the quantity of information generated, and that prototyping should begin as soon as possible during the design process. Ramifications of these findings are discussed in the context of educating future designers on the efficient use of design tools.

A new concept of Phase Change Materials (PCM) device has recently been developed to improve the thermal control of spacecraft. Two Phase Change Material candidates have been selected after extensive testing of a set of available materials. Special attention has been paid to the hysteresis and ageing. In the design of the container, the thermal expansion of the PCM is a critical parameter that has been taken into consideration by two competing technologies. These designs have been tested: a prototype of PCM heat storage device has been effectivelymanufactured and tested under vacuum environment. 1D and 2D mathematical models have been developed. Conclusions are drawn to promote the use of PCM Heat Storage device in various space missions.

In opposition to traditional machining in which part is manufactured by material removal, rapid prototyping techniques allow parts manufacturing by material addition. The part is built layer-by-layer and the sum of all layers creates the part. Currently, several techniques exist. They use different kind of materials (metals, ceramics, polymers) and technologies (laser melting, laser polymerising, 3D-printing, cladding, ...). Some of these techniques can deal with nanometric particles. In the case of which a near net shape part is built and must be sintered after shaping, the addition of nano-particles can be useful for sintering by increasing specific surface and reactivity of the batch or by improving the properties of the material. An overview about techniques of rapid prototyping allowing the processing of nanomaterials will be discussed. Tests have been done using Optoform process. This process uses a laser to polymerize a paste made of photo-curable resin loaded with powdered material. Nano-particles can be added and stabilized in the paste. In this presentation, the results obtained with both systems Al2O3 + nano Zr02 and SiC + Nano SiC will be discussed.
