“…cellulose or starch based) to the ceramic powder. 11 As the binder liquid spreads through the powder driven by capillary forces, the applied liquid remained in the desired locations, which resulted in a well defined structure. The disadvantages were the necessity for sparing application of the binder solution, the poor mechanical strength exhibited by the samples and the long drying period, which may potentially lead to dimensional instability.…”

Three-dimensional powder printing was used in this study to fabricate custom made magnesium phosphate based structures. In a first step, farringtonite [Mg 3 (PO 4 ) 2 ] powders were synthesised by sintering and subsequent grinding. Optimised powders suitable for printing were obtained after 60 min of grinding, which resulted in a medium particle size of 16 mm. These powders were reacted with binder liquids consisting of 2M K 2 HPO 4 , 0?5M (NH 4 ) 2 HPO 4 or 20%H 3 PO 4 to form a matrix of either struvite-(K) (MgKPO 4 .6H 2 O), struvite (MgNH 4 PO 4 .6H 2 O) or newberyite (MgHPO 4 .3H 2 O) by a hydraulic setting reaction. While printing of struvite-(K) was not possible due to the long setting time of this cement system, both newberyite and struvite samples could be processed with good dimensional accuracy. Strength was initially low after printing, namely in the range of 1?3-2?8 MPa; however, additional post-hardening in the binders increased the compressive strength to a maximum of 10 MPa for struvite and 36 MPa for newberyite. This was accompanied by a higher degree of conversion to the setting products, as evidenced by Xray diffraction analysis. Magnesium phosphate based structures prepared by three-dimensional printing may find an application as biodegradable bone substitutes or can be used for the rapid manufacturing of moulds for metal casting, as demonstrated in this study.

Binder jet additive manufacturing enables the production of complex components for numerous applications. Binder jetting is the only powder bed additive manufacturing process that is not fusion-based, thus manufactured parts have no residual stresses as opposed to laser-based additive manufacturing processes. Binder jet technology can be adopted for the production of various small and large metallic parts for specific applications, including in the biomedical and energy sectors, at a lower cost and shorter lead time. One of the most well-known types of stainless steels for various industries is 316L, which has been extensively manufactured using binder jet technology. Binder jet manufactured 316L parts have obtained near full density and, in some cases, similar mechanical properties compared to conventionally manufactured parts. This article introduces methods, principles, and applications of binder jetting of SS 316L. Details of binder jetting processes, including powder characteristics (shape and size), binder properties (binder chemistry and droplet formation mechanism), printing process parameters (such as layer thickness, binder saturation, drying time), and post-processing sintering mechanism and densification processes, are carefully reviewed. Furthermore, critical factors in the selection of feedstock, printing parameters, sintering temperature, time, atmosphere, and heating rate of 316L binder jet manufactured parts are highlighted and summarized. Finally, the above-mentioned processing parameters are correlated with final density and mechanical properties of 316L components to establish a guideline on feedstock selection and process parameters optimization to achieve desired density, structure and properties for various applications.

“…In another study, Butscher et al [14] systematically analyzed the relationship between layer thickness and layer stability with the quality of the final printed specimens. Alternatively, Suwanprateeb et al [15] prepared adhesive pre-coated hydroxyapatite powders using hot plate drying coupled with a grinding technique with the aim of increasing the mechanical properties of 3D printed samples.…”

a b s t r a c tAdditive manufacturing methods such as three-dimensional printing (3DP) show a great potential for production of porous structure with complex internal and external structures for bone tissue engineering applications. To optimize the 3DP manufacturing process and to produce 3D printed parts with the requisite architecture and strength, there was a need to fine-tune the printing parameters. The purpose of this study was to develop optimal processing parameters based on a design of the experiments approach to evaluate the ability of 3DP for making calcium sulfate-based scaffold prototypes. The major printing parameters examined in this study were layer thickness, delay time of spreading the next layer, and build orientation of the specimens. Scaffold dimensional accuracy, porosity, and mechanical stiffness were systematically investigated using a design of experiment approach. Resulting macro-porous structures were also studied to evaluate the potential of 3DP technology for meeting the small-scale geometric requirements of bone scaffolds. Signal-to-noise ratio and analysis of variance (ANOVA) were employed to identify the important factors that influence optimal 3D printed part characteristics. The results showed that samples built using the minimum layer thickness (89 mm) and x-direction of build bed with 300 ms delay time between spreading each layer yielded the highest quality scaffold prototypes; thus, these parameters are suggested for fabrication of an engineered bone tissue scaffold. Furthermore, this study identified orientation and new layer spreading delay time as the most important factors influencing the dimensional accuracy, compressive strength, and porosity of the samples.
