Rapid Prototyping for Rapid Product Development

Introduction

The course will explain the working principles of the mature technologies and compare their strengths and weaknesses. Video presentation of the SLA, Polyjet, SGC, LOM, FDM, SLS and 3DP processes and parts made by theses processes and several other processes will be exhibited. Industrial examples from various applications (including aerospace, automobile, jewelry, coin, biomedical engineering, etc.”) will be illustrated.

Course Objectives

Opposed to a conventional machining process which takes away excess material from a block of work piece, 3-Dimensional Rapid Prototyping and Manufacturing (3DRPM) produce parts by building one layer upon another in a horizontal manner. This offers many advantages over machining limitations such as the capability to produce complex and difficult-to-machine models (e.g. A sphere in a thin-necked bottle, straight corners of pockets in typical engineering components, small, intricate jewellery ring). Jigs and fixtures are also no longer needed.

Because 3DRPM is linked to CAD/CAM systems, it is able to produce a component in a short turn around time. As a result, it has great potential, especially for today’s products, which have very short product life.

There are currently no less than 30 different 3DRPM namely, Stereolithography (SLA), Solid Ground Curing (SGC), Selective Laser Sintering (SLS), Laminated Object Manufacturing (LOM), Fused Deposition Modeling, Direct Shell Production Casting (DSPC), Multiphase Jet Solidification (MJS), and EOS’s EOSINT Systems. Among the newest systems are CAM-LEM’s CL 100, Shape Deposition Manufacturing, Acrom’s Electro Beam Melting and Aeromet Corporation’s Lasform Technology.

Trainer(s)

Associate Professor Chua, Chee Kai

Dr Chua Chee Kai is an Associate Professor and the Head, Division of Systems and Engineering Management, at the School of Mechanical & Aerospace Engineering in Nanyang Technological University, Singapore. He holds a PhD, Nan, Tech., M.Sc (Ind), B.Eng (Mech), NUS’pore.

Dr Chua has been involved in Rapid Prototyping (RP) since 1990. At NTU, he has helped in the application of RP to products like consumer goods, coins, jewelleries and bio-medical applications. On-going research at NTU include development of pre-processors, solving orientation and support issues, finishing techniques for post-processing of parts, expert system for selection of RP systems and development of new techniques of RP.

He has been invited as a keynote speaker to two local conferences to speak on the “Trends of Rapid Prototyping” in 1994. He has sat on the International Programme Committee for 10 International Conferences devoted to Rapid Prototyping and has been consulted by industries on Rapid Prototyping-related problems. He has contributed more than 140 publications in local seminars, technical talks, international conferences, journals, books, books chapters and patent. He conducted this course more than 20 times since 1991 for the industry in Singapore, once in 1995 for the Wuhan Automotive University Polytechnic, China, and three times in-house in a multinational company.

Dr Chua is the co-author of the book, entitles “Rapid Prototyping: Principles & Applications in manufacturing” published by John Wiley & Sons in 1997 and a Chinese version was published subsequently in 1998. The 2nd edition entitled “Rapid Prototyping: Principles and Applications” was published in February 2003 by World Scientific Publishing. Since 2000, he has become a member of the Editorial Advisory Board o the Rapid Prototyping Journal published by MCB University Press, UK.

In 2005, he co-founded a new international journal “Virtual and Physical Prototyping”, published by Francis and Taylor.

Who Should Attend

Technicians and engineers who are involved in product design, modeling and prototyping, tool and dies design and manufacturing. Lecturers teaching the subject of design may also be interested. Others who are keen to follow this immensely interesting and new technology may also wish to attend.
