“…According to Brooks and Aitchison, the incorporation of polystyrene in rapid prototyping has different uses such as: conceptual design of commercial products, automotive design, aerodynamic and hydrodynamic testing, among others. Rapid Heat Ablation (RHA) is presented ( Kim, Lee, & Yang, 2007 ) as a method to improve the cutting mechanism, and to solve the problems of excessive cutting time and leftover material by developing a new material removal method. The objective is to reduce the heat-affected zone, thus with the support of TRIZ for guiding the conceptual design Kim et al formulated the problem as a physical contradiction.…”

“…Contrary to Kim et al ( 2007 ) where the authors based their solution in the formulation of a physical contradiction, in this example we formulated the problem as a technical contradiction. The contradiction formulated to propose the solution is composed by the positive characteristic Temperature and the negative characteristic object-affected harmful effects.…”

In the industrial context, an interest exists in the collective resolution of creative problems during the conceptual design phase. In this work we introduce an information-based software framework useful to collaborate for inventive problems solving. This framework proposes the implementation of techniques from the Collective Intelligence (CI) research field in combination with the systematic methods provided by the TRIZ theory. Both approaches are centered in the human aspect of the innovation process, and are complementary. While CI focuses on the intelligent behavior that emerges in collaborative work, the TRIZ theory is centered in the individual capacity to solve problems systematically. The framework's objective is to improve the individual creativity provided by the TRIZ method and tools, with the value created by the collective contributions. This work aims to contribute formulating the basis to extend the research field of Computer Aided Innovation, to the next evolutionary step called "Open CAI 2.0".

“…The researchers at KAIST (Kim et al) have also published a number of papers describing a novel hot tool which is used to ablate plastic foams [26][27][28]. The process which the authors call rapid heat ablation (RHA), involves the use of a specially designed hot tool shaped similarly to a ball-end mill to create new surfaces by ablating foam.…”

Current additive rapid prototyping technologies fail to efficiently produce objects greater than 0.5m³ due to restrictions in build size and build time. Conversely large hot-wire cutting machines, able to cut large objects, often lack the ability to create surfaces with complex geometrical features. Therefore there is a need to develop rapid prototyping and manufacturing technologies capable of producing large objects in a rapid manner directly from CAD data. Large sized freeform objects made of soft materials, such as polystyrene foam, have numerous uses including; conceptual design of commercial products, automotive design, aerodynamic and hydrodynamic testing, advertising, film making, medical supports, sporting equipment and props for the entertainment industry. Plastic foam cutting rapid prototyping is a relatively new technology capable of producing large plastic foam objects directly from CAD data. This paper will describe nine such technologies that have been developed or are currently being developed at institutions around the world.

The findings reported in this paper provide a model for consistently achieving optimal cutting conditions when shaping foam plastic, such as polystyrene, with an electrically heated wire-based cutting tool. General relationships between wire temperature, power input, feed-rate, kerf width and work piece material composition were developed and an optimal machining algorithm was proposed and tested. The findings provide a significant advancement toward a fully automated machining facility and the associated development of a novel, large scale rapid manufacturing (RM) system.
