Ceramic Binder Jetting Additive Manufacturing: A Literature Review on Density

Abstract

The objective of this review paper is to summarize the current status and identify the knowledge gaps in ceramic binder jetting additive manufacturing, with a particular focus on density. This paper begins with an overview of ceramic binder jetting. Then, it discusses different aspects of density, including various terminologies, measurement methods, and achieved values. Afterward, it reviews two categories of techniques to increase the part density: material preparation techniques (powder granulation, mixing powders of different sizes, using slurry feedstock, and mixing different materials) and postprocessing techniques (sintering, chemical reaction, infiltration, and isostatic pressing). Finally, it presents the knowledge gaps in the literature.

Influence of the Infill Orientation on the Properties of Zirconia Parts Produced by Fused Filament Fabrication

“…Since the simple Archimedes’ method was used to measure the density of the parts, some water could penetrate the open porosity at the surface of the specimens. Therefore, the density shown in Table 1 is the apparent density, and not the bulk density [ 7 ]. The apparent density of the feedstock was also measured, as the helium used in the pycnometer measurements could penetrate the outer pores of the pellets.…”

“…Among the many technologies that have been developed in the last years [ 2 , 3 , 4 , 5 , 6 ], the four most relevant process categories are [ 1 ] vat photopolymerization (VPP), binder jetting (BJT), material jetting (MJT) and material extrusion (MEX). Each additive manufacturing technique has different advantages and disadvantages in terms of speed, dimensional accuracy, properties of the final components and costs [ 2 , 3 , 4 , 5 , 6 , 7 ]. Therefore, the feasibility of using one technique or another depends on the application.…”

Additive manufacturing of powder components based on subtractive sintering approach

“…Powder-based 3D printing is an attractive technology because as opposed to many other 3D printing techniques, it does not require support material (Du et al, 2020;Shirazi et al, 2015). Powder solidification happens either with a laser or with a binder depending on the technique being used.…”

A Capstone Experience Through the Development of a Powder Compaction System During COVID-19 Pandemic

“…A powder compaction system can be useful to various manufacturing technologies, such as powder metallurgy [1] and additive manufacturing [2][3][4][5]. In powder metallurgy, a powder compaction system can be used to tune green density before sintering [1].…”

“…In powder metallurgy, a powder compaction system can be used to tune green density before sintering [1]. In additive manufacturing (e.g., powder bed fusion and binder jetting) [2][3][4][5], a powder compaction system can be used to improve powder bed density. In order to develop a powder compaction system, a capstone team with four senior students was formed.…”
