Abstract

The purpose of this study is to replicate the melaka historical artifacts made using selective laser sintering(SLS). This research was applied a Non-contact it is a reverse engineering (RE) and powder-based is additive manufacturing(AM) systems to execute this project. The main issues highlighted in this study is replicate the melaka historical artifacts to preserve its original condition. In this issue also to compare the dimensional accuracy of prototype product with the original product of historical artifact. Furthermore, the primary research and secondary research was collected to execute this project. This case study demonstrates the most effective restoration and reproduction techniques for the historical artefact. The data was collected by STL file from captured the scanned object from previous experiment, will go thru pre-processing, post-processing and conversion steps before its fabricate using additive manufacturing system by using method process Selective Laser Sintering (SLS). However, PolyWorks, Solidwork and Materialise Magic software was used to includes filling in holes, removing useless parts, and smoothing the surface. Direct STL file creation from scanned data is helpful to reduce time and mistakes in the modelling process. The quality of the STL data from the T-SCAN scanners was verified by Materialise Magic and Buildstar sofwares to analyse CAD-Part, Part-Part and visual inspection. This research will be focusing on laser sintering process as it will be used in fabrication process. Furthermore, the purpose of this study is to identify the dimensional accuracy of historical Pemuras using reverse engineering (RE) and additive manufacturing (AM). This is to compare the dimensional accuracy of original product and prototype product.
