Rapid Prototyping For Rapid Product Development

Course Objectives
i1 i2

Opposed to a conventional machining process which takes away excess material from a block of workpiece, 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 (eg. a sphere in a thin-necked bottle, straight corners of pockets in typical engineering components, a 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 Modelling (FDM), Three-Dimensional Printing (3DP), Objet’s Polyjet Technology, Two-Laser-Beam Technology, Solid Creation System (SCS), Micro-Fabrication, Multi-Jet 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 Electron Beam Melting and Aeromet Corporation's Lasform Technology. The course will explain the working principles of the mature technologies and compare their strengths and weaknesses.

Video presentation of the SLA, Polyjet, LOM, FDM, SLS and 3DP processes and parts made by these processes and several other processes will be exhibited. Industrial examples from various applications (including aerospace, automobile, jewelry, coin, biomedical engineering, etc.") will be illustrated.

Who Should Attend

Technicians and engineers who are involved in product design, modelling and prototyping, tool and die 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.
Besides this public course, companies and institutions can request for specific, customized inhouse courses. Companies which have done so in the past include Maxtor, Thomson Multimedia, Defence Science Technology, SIMTech, Institute of Technical Education, Tyco Electronics and NUS High School of Mathematics and Science.
