Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

Advanced Materials Technologies, EarlyView.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.

Improved mechanical quality of ceramic vat photopolymerization prints by supercritical carbon dioxide extraction

Open Ceramics
Vat photopolymerization (VPP) enables 3D printing of dense ceramics with complex structures, however the mandatory thermal pre-conditioning and debinding steps to remove the organic substances, can last 7 days.

Fatigue Strength in Additive Toolmaking: A Study of Metal Binder Jetting and Electron Beam Melting for Processing Carbide‐Rich Cold‐Work Tool Steels

steel research international, EarlyView.
Focusing on the critical tap hole region of the blast furnace, this work examines binder characteristics, prepares tap hole clay with different formulations, and evaluates their physical properties. The findings confirm the advantages of composite binders and offer a new binder option for tap hole clay.

Effect of Cigarette Smoking on the Surface Roughness, Color, and Translucency of Zirconia Produced by Additive and Subtractive Manufacturing

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To compare the surface roughness, color stability, and translucency of zirconia produced by additive manufacturing (AM) and subtractive manufacturing (SM) after exposure to cigarette smoking. Materials and Methods A total of 60 disc‐shaped specimens were fabricated from 2 methods: AM (INNI Cera BCM W500/1000) and SM (VITA YZ T).

Bond strength enhancement for additively manufactured zirconia: Micro‐retentive design approach

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of digitally designed micro‐retention features on the bond strength of additively manufactured (AM) zirconia copings. Materials and Methods Sixty titanium base abutments (NobelParallel, NobelBiocare), pretreated with 50 µm alumina particles were divided into four groups (n = 15 per group); one group with ...

A hybrid material extrusion device with local debinding and sintering

Materials Today Communications, 2023
To date, debinding and sintering of parts fabricated through material extrusion (MEX) has been done in a time-consuming disconnected approach, with geometries initially shaped, then debinded and lastly sintered. Little progress has been made to process MEX bodies within the same device, eliminating part transportation to sophisticate and expensive ...

Translucency of 3D‐Printed 3Y‐ and 5Y‐Doped Zirconia

Journal of Esthetic and Restorative Dentistry, Volume 38, Issue 9, Page 1708-1716, September 2026.
ABSTRACT Objectives To evaluate and compare the translucency of 3D‐printed zirconia materials: 3Y tetragonal zirconia polycrystal (3Y‐TZP) and 5Y partially stabilized zirconia (5Y‐PSZ). Material and Methods 3D‐printed 5Y‐PSZ and 3Y‐TZP materials fabricated using digital light processing (DLP) were investigated.
