RAPID prototyping, TECHNOLOGICAL innovations, AUTOMATION, and THREE-dimensional printing
The article offers information on the advent of fourth-dimensional (4D) printing, the convergence of smart materials and 3D printing technology, which has the ability to revolutionize automation. It is said that 4D technology can change not only how things get made but what they can do. Efforts of a team led by Anna C. Balazs, professor of chemical engineering in the University of Pittsburgh's Swanson School of Engineering, Pennsylvania, in this field is described.

MANUFACTURING processes, PRODUCTION engineering, TECHNOLOGICAL innovations, RAPID prototyping, INDUSTRIAL engineering, AUTOMATION, PRODUCTION methods, and PRODUCTION management (Manufacturing)
Making goods evolved over several centuries from craft production to complex and highly automated manufacturing processes. A companion paper by R. Jaikumar documents the transformation of firearms manufacture through six distinct epochs, each accompanied by radical changes in the nature of work. These shifts were enabled by corresponding changes in technological knowledge. This paper models knowledge about manufacturing methods as a directed graph of cause-effect relationships. Increasing knowledge corresponds to more numerous variables (nodes) and relationships (arcs). The more dense the graph, the more variables can be monitored and controlled, with greater precision. This enables higher production speeds, tighter tolerances, and higher quality. Changes in knowledge from epoch to epoch tend to follow consistent patterns. More is learned about key classes of phenomena, including measurement methods, feedback control methods, and disturbances. As knowledge increases, control becomes more formal, and operator discretion is reduced or shifted to other types of activity. Increasing knowledge and control are two dimensions of a shift from art towards science. Evolution from art to science is not monotonic. The knowledge graphs of new processes are riddled with holes; dozens of new variables must be identified, understood, and controlled. Frederick Taylor pioneered three key methods of developing causal knowledge in such situations: reductionism, using systems of quantitative equations to express knowledge, and learning by systematic experimentation. Using causal networks to formally model knowledge appears to also fit other kinds of technology. But even as vital aspects of manufacturing verge on ‘full science,’ other technological activities will remain nearer to art, as for them complete knowledge is unapproachable. [ABSTRACT FROM AUTHOR]

This paper describes a software-based approach for the design, modelling and simulation of automated and semi-automated construction. It proposes that, through the use of currently available software, it is possible to attain the project definition phase for new robotic devices without the need for fabricating prototypes. The use of two different models for the simulation of on-site work cells is proposed. The lint looks into the physical operations of new construction robots. The second examines the influence that the automation of the target operations in the construction process could have. The paper includes a description of the logical process and sample software tools plus applications that can be used towards the development of a computer-aided design construction automation environment. Emphasis is put on the use of kinematic and discrete-event simulation techniques. A comparison of this approach with full prototyping undertake by certain large contractors is presented.

The paper presents work on the development of a build-time estimator for rapid manufacturing. A time estimator is required to develop a comprehensive costing tool for rapid manufacturing. An empirical method was used to estimate build times using both simulated and actual builds for a laser sintering machine. The estimator presented herein is based upon object geometry and, therefore, the fundamental data driving the model are obtainable from current three-dimensional computer-aided design models. The aim is to define a model describing the build times for a laser sintering machine either for single or multiple objects. [ABSTRACT FROM AUTHOR]
