Summary: This study aimed to increase the manufacturing speed of binder jetting by using adaptive slicing and a variable binder amount algorithm. The results showed that similar surface quality can be achieved by using fewer layers compared to uniform slicing. This study provides a new approach for implementing adaptive slicing and variable binder amounts in binder jetting.

Summary: A large volume binder jetting printer was used to fabricate prism-shaped geopolymer components. Results showed that printed geopolymer parts, fabricated with the addition of 30 wt% metakaolin, possessed high compressive strength and low porosity, with no significant variation in strength observed after being submerged in water for 1 week.

Summary: This study investigated the properties of geopolymer mixtures based on agricultural wastes, including compressive strength, flexural strength, capillary water absorption, dry shrinkage, resistance to freeze-thaw cycles, and high temperature resistance. The Taguchi method was used to design experiments and optimize factors in order to predict the properties of the mixtures without conducting full-scale experimental works. Various factors were considered, such as curing method, concentration of sodium hydroxide solution, mass ratio of alkaline activator to binder, mass ratio of sodium silicate to sodium hydroxide, type of fiber, and fiber volume. The results showed that the optimal levels of most factors were consistent across different tests, except for the type of fiber.

Summary: Porous ceramics have a wide range of industrial applications due to their excellent thermal insulation and physical properties. However, conventional manufacturing processes have limitations in terms of pore control and geometric design. Recent studies have focused on using additive manufacturing techniques, particularly binder jetting, to overcome these limitations. This study demonstrates an optimal process for fabricating porous ceramics using binder jetting technology, including optimizing powder flowability and compatibility, and investigating the effects of glass frit addition and sintering temperature adjustment on the final product's microstructure, porosity, and mechanical properties. Computational fluid dynamics was also used to design improved filter structures for better filtering efficiency using the optimized ceramic powder and binder jetting technique.

Summary: In binder jetting additive manufacturing, the liquid binder plays a crucial role in binding the powder particles together and providing structural integrity to the green parts. However, the impact of the binder on part densification and subsequent part properties is still not well understood. This study investigates the influence of the binder on densification through a new approach called shell printing, which allows for varying the amount of binder content in the green parts. By selectively depositing the binder around the part surface, the packed powders are trapped inside the bound shell geometry and can be sintered to densify the part. Manipulating the shell thickness enables the exploration of the effects of the binder content on the process-structure-property relationships.

Summary: This work develops a high-fidelity computational model to simulate the fluid-solid interaction between binder and powder in binder jetting additive manufacturing. The model accurately reproduces the behavior of binder droplets and powder particles, including impingement, spreading, penetration, spattering, and agglomeration. The study also compares the effects of sequential and simultaneous binder jetting on powder spattering and dimensional accuracy.

Summary: Infiltration of ceramic suspension is an effective method to enhance density and properties of printed binder-jetted parts. This study reported significant improvements of alumina parts using this combination printing-infiltration technique. The density of the parts increased to 87.9 +/- 0.5% of the theoretical density after infiltration of a pre-consolidated body.
