Abstract
Additive manufacturing has been of interest in the recent years due to its popularity in small scale production and rapid prototyping. There is a wide variety of additive manufacturing processes that are practiced today such as Material Extrusion, Material Jetting, Binder Jetting and more. Although, quite a few of these processes generally offer low build rate, resolution and mechanical performance when compared to other machining processes. To overcome these flaws, a technique called Multi Jet Fusion (MJF) has been developed by HP in 2016. MJF utilizes an inkjet array of fusing and detailing agents that are carefully applied across a bed of powdered material layer by layer, which then are fused together by a heating element. MJF offers low machining time, competitive part properties and minimal post production finishing, which all are desirable for various industry applications. In this paper, a comprehensive review of MJF technology will be presented. The review will discuss and evaluate principle operation of MJF, current knowledge of material characteristics, chemical, thermal, and mechanical properties of printed parts, parameters affecting the properties, its potential when compared to other similar technologies and future scope. This paper shall help serve as a guideline for 3D printing with MJF technology in the industry.
