Product Focused Freeform Fabrication Education
Presented in this paper is our experience of teaching freeform fabrication to students at
the Missouri University of Science and Technology, and to high school students and
teachers. The emphasis of the curriculum is exposing students to rapid product
development technologies with the goal of creating awareness to emerging career
opportunities in CAD/CAM. Starting from solid modeling, principles of freeform
fabrication, to applications of rapid prototyping and manufacturing in industry sponsored
product development projects, students can learn in-depth freeform fabrication
technologies. Interactive course content with hands-on experience for product
development is the key towards the success of the program.Mechanical Engineerin
Geometrical Product Specification and Verification as toolbox to meet up-to-date technical requirements
The ISO standards for the Geometrical Product Specification and Verification (GPS) define an internationally uniform description
language, that allows expressing unambiguously and completely all requirements for the geometry of a product with the corresponding
requirements for the inspection process in technical drawings, taking into account current possibilities of measurement and testing
technology. The practice shows that the university curricula of the mechanical engineering faculties often include only limited classes on
the GPS, mostly as part of curriculum of subjects like Metrology or Fundamentals of Machine Design. This does not allow students to
gain enough knowledge on the subject. Currently there is no coherent EU-wide provision for vocational training (VET) in this area.

From art to engineering
This paper describes work which emerged through a need to understand more about the potential of laser surface engineering for use in the creative industries. The method of creation of contemporary jewellery pieces and the resultant âOcularâ jewellery series are described from the points of view of an artist and an engineer. The work demonstrates how laser controlled oxide growth on commercially pure titanium under ambient conditions can be used as an artistic tool by producing even, defined colours or by reproducing a simulation of freehand drawings on a titanium surface. It also asks the question: how different are artists from scientists and engineers
Laser surface colouring of titanium for contemporary jewellery
This paper describes work which emerged through a need to understand more about the potential of laser surface engineering for use in the creative industries. The method of creation of contemporary jewellery pieces and the resultant 'Ocular' jewellery series are described from the creative point of view. The work demonstrates how laser controlled oxide growth on Tiâ6Alâ4V alloy under ambient conditions can be used as an artistic tool by producing precisely defined colours. Use of the method to produce regular areas of even colour and to reproduce freehand drawings on a titanium alloy surface is described. Analysis highlights interference as the main colouring mechanism and suggests a graded surface layer, progressing from an outer layer of TiO2 to lower layers rich in TiO and Ti2O. The model of research by practice presented in this paper offers a contribution to the current debate on partnerships between art and science and engineering
