“…Abdolreza Simchi et al [10] researched the challenges of using binder jet 3D printing technology to fabricate biomedical grade titanium alloys with high-density, fine microstructure, and low impurity pickup. A particle size distribution with a mean diameter of around 20 µm and large span and positive skewness to achieve green parts with a density of 65±1% PFD (pore-free density) was proposed in their study.…”

Prototyping is frequently performed using Additive Manufacturing (AM), which has practical usages in the aerospace, defence, medical, and automotive industries. AM is a viable alternative to the established powder metallurgy method that guarantees a good and enhanced surface polish. The primary purpose of the current study is to optimize the printing process parameters related to binder jet printing technology. In the additive manufacturing technique known as ‘binder jetting,’ a commercial printer selectively applies a liquid binding agent to a thin coating of powder particles. The parameters governing AM process includes roller speed, layer thickness, infill density and bed temperature. Taguchi analysis based on L16 orthogonal array is adapted in the study to optimize the various process parameters. The output responses namely ultimate tensile strength and toughness properties were evaluated to optimize the process. Tensile testing is carried out as per ASTM standard. The study also involves the observation of the binder jet process, associative science of densification after sintering, evolution of microstructural characteristics of the binder jetted part and application of the optimized process parameters of selected material.
