Multi‐Material Gradient Printing Using Meniscus‐enabled Projection Stereolithography (MAPS)

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
MAPS is a new vat‐free printing technique that utilizes programmed delivery of resin droplets with custom formulations to enable multi‐material gradient printing of 3D structures with user‐defined variations in mechanical stiffness, opacity, surface energy, cell densities, and magnetic properties. Abstract Light‐based additive manufacturing methods are

Large-bore tapered-roller bearing performance and endurance to 2.4 million DN [PDF]

open access: yes, 1983
The operating characteristics and experimental life estimates for 120.65 mm bore tapered roller bearings of two designs under combined radial and thrust loads were determined. A modified standard bearing design was tested at speeds up to 15,000 rpm.

A Sleeve Alters the Pressure‐Stretch Curve of a Hyperelastic Balloon to Enable Pre‐Programmed Sequencing

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Direct Ink Writing 3D Printing of Recyclable and Thermally Stable Vitrimers

open access: yesAdvanced Materials Technologies, EarlyView.
Vitrimers hold great promise in additive manufacturing as defect‐insensitive, repairable, and recyclable feedstocks. A thin‐film additively manufactured process is developed for a high‐performance vitrimer that is difficult to process traditionally.

Laser‐Based Solidification of Cermets/Cemented Carbides: Processing‐Microstructure‐Property Relationships

open access: yesAdvanced Materials Technologies, EarlyView.
Recent research on laser‐processed cermets and cemented carbides highlights significant advancements, yet a notable paucity of studies and persistent challenges remain. Efforts are increasingly focused on developing low‐cost, environmentally friendly cermets as alternatives to conventional materials.
