Abstract

Despite the use of Additive Manufacturing (AM) technologies in a lot of applications including the production of some high-value products for end use, it is still very much an untapped potential. T...

Highlights

  • Additive Manufacturing (AM) processes can be defined as semi-automated systems that take two-dimensional (2-D) layers of computer data and rebuild them into three-dimensional (3D) solid objects

  • Rapid Manufacturing (RM) has evolved from Rapid Prototyping (RP) which typically used AM technologies to physically create prototype models and concepts prior to committing to a subsequent alternative or downstream manufacturing operation (Mellor, Hao, & Zhang, 2014), RM being concerned with the direct manufacture of functional parts, components and assemblies using AM technologies (Tuck, Hague, & Burns, 2006)

  • Following is the primary research question that the study investigated: “What are the requirements or pre-requisites for RM technologies to be used as viable means to manufacture end used products in mass scale?”

Summary

Introduction

Additive Manufacturing (AM) processes can be defined as semi-automated systems that take two-dimensional (2-D) layers of computer data and rebuild them into three-dimensional (3D) solid objects. RM has evolved from Rapid Prototyping (RP) which typically used AM technologies to physically create prototype models and concepts prior to committing to a subsequent alternative or downstream manufacturing operation (Mellor, Hao, & Zhang, 2014), RM being concerned with the direct manufacture of functional parts, components and assemblies using AM technologies (Tuck, Hague, & Burns, 2006). AM produces components in an additive manner by slicing a 3D computer-aided design (CAD) model into a series of discrete layers or crosssections. These layers are reconstructed in the AM machine to produce a physical representation of the 3D CAD model (Ruffo, Tuck, & Hague, 2007). One particular advantage over more traditional techniques is that no tooling is required to manufacture a component (Tuck, Hague, Ruffo, Ransley, & Adams, 2008)
