iCAT 2014 Invited lectures

There are major forces reverberating through our world today - impacting individuals, companies and industries alike, including those involved in additive manufacturing. The key questions to be addressed are:

In the near future 3D printing will have a marked effect on how we order, design, and manufacture products. They will have a major Impact not just on products, but on our society, and how we live and do business.

Understanding the challenges concerning the intellectual property (IP) rights associated with additive manufacturing is key to the development and use of this technology.

Andy Christensen has been active in the additive manufacturing (AM) industry since the early 1990’s.  From 2000 to 2014 he was the President and Owner of Medical Modeling Inc., a world-leading medical device AM service bureau based in Golden, Colorado.  

Patients in the cranio-maxillofacial clinic often present with serious, complex, and potentially life- threatening or life-limiting medical conditions (e.g. tumor, trauma, aggressive osteomyelitis). Available treatments may not always give satisfactory results for patients and doctors.

This paper reports investigations into the potential for consumers to actively design their own desired products and thereafter to endorse them for manufacture. This idea emerged in anticipation of the rapid growth of low-cost fabrication technology, particularly 3D Printing.

With almost unlimited freedom of design, additive manufacturing technologies open up new perspectives to achieve individual solutions. These types of manufacturing techniques barely set any limits to the spirit of innovation. Due to this fact additive manufacturing techniques follow the trend towards customized products and will allow for serial production in the future.

Following some of Michael Porter’s theses, Deon will discuss how age old industries can be turned around, using a fresh and innovative approach, using CAD, CAM, Reverse Engineering, Additive Manufacturing and Rapid Tooling. Some aspects of regional innovation and regional economic development, as a further tier of beneficiation, will also be discussed.

In the field of ceramic processing there is a strong need for the introduction of Additive Manufacturing (AM) techniques. Tools for powder injection molding (PIM) are very expensive and Rolex Explorer Replica require significant lead times which severely restrict the suitability of PIM for the production of small scale series or customized products; however, no adequate prototyping technology existed so far.

The presentation will focus on three selected case studies of designing, manufacturing and application of custom implants. They include two cranial implants and one large maxillofacial implant. The implants were designed while minimising their weights and applying porous titanium structures.

A defective glenoid with pore bone stock is the most challenging problem in the shoulder endoprosthetic (EP). For these severe cases mostly a bone graft for restoration of glenoid shape and implant position in the functional plane is needed.
