Effect of Powder Type on Slurries for Additive Manufacturing of Sodium Potassium Niobate Piezoceramics

International Journal of Applied Ceramic Technology, Volume 23, Issue 4, August 2026.
ABSTRACT Due to its enhanced design flexibility, additive manufacturing (AM) is a game‐changing technology for piezoelectric ceramics. Still, to achieve a high‐quality ceramic by AM, slurry preparation is critical. Piezoceramics based on potassium sodium niobate [(K, Na)NbO3] (KNN) are challenging to densify and therefore require extra care during ...

Textured Piezoelectric Ceramics Printed With Baffled Nozzles

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
To better align platelet particles in additively manufactured textured ceramics, baffled nozzles were simulated and tested. The simulation included a novel CFD heuristic that considers the entire print path. Printed parts were characterized via microscopy, X‐ray diffraction, and electromechanically and results were compared to the simulation, finding ...

Solvent Debinding of MIM Parts in a Polystyrene-Palm Oil Based Binder System

IOP Conference Series: Materials Science and Engineering, 2016
Abstract The influence of the leaching temperatures on the solvent debinding process of SS316L stainless steel alloy compact has been investigated. Solvent debinding process of injection moulded SS316L feedstock was conducted to eliminate palm kernel oil by using n- heptane solution at various temperatures of 40, 50 and 60°C and at ...

Improvement of the Dimensional Stability of Powder Injection Molded Compacts by Adding Swelling Inhibitor into the Debinding Solvent [PDF]

Metallurgical and Materials Transactions A, 2007
Defects are frequently found in powder injection molded (PIM) compacts during solvent debinding due to the swelling of the binders. This problem can be alleviated by adjusting the composition of the debinding solvent. In this study, 10 vol pct swelling inhibitors were added into heptane, and the in-situ amounts of swelling and sagging of the specimen ...

The effect of toothpaste and thermal aging on extrinsically stained additively manufactured zirconia: A comparative study on surface roughness and stain durability

Journal of Prosthodontics, Volume 35, Issue 7, Page 1114-1123, August 2026.
Abstract Purpose The purpose of this in vitro study was to compare the average surface roughness (Ra) and stain durability of extrinsically stained additively manufactured zirconia, after brushing with different toothpastes and thermal cycling, with those of subtractively manufactured zirconia and lithium disilicate.

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics

Advanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.
Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.
