MXene 3D‐AJP: Three‐Dimensional Well‐Oriented Freeform Networks of 2D MXene Nanosheets via Aerosol‐Based 3D Printing

Small, EarlyView.
This study presents an additive‐free aerosol jet 3D printing technique for assembling 2D MXene nanosheets into complex, customizable, high‐aspect‐ratio 3D microarchitectures without binders. By leveraging real‐time ink thickening, the authors also fabricate 3D microsupercapacitors with interdigitated electrodes that holds breakthrough device areal ...

Supramolecular Chiral Assembly of Open‐Shell Quinoids With Chiral Additives and Their Spin‐Dependent Transport in Magneto Field‐Effect Transistors

Small, EarlyView.
Open‐shell quinoids with intrinsic spins are assembled into chiral supramolecular structures via blending with chiral additives. Thermal annealing induces stable co‐crystallization, leading to a 30‐fold amplification of chirality (gabs = 1.23 × 10−2). Significantly, this study represents the first integration of spin‐possessing chiral assemblies into ...

Selective Laser Sintering

2001
For a given material system, the laser energy density, E s is a key factor which affects quality of the laser sintered structure. A laser energy density is defined by the laser power, laser scan speed and laser beam spot size: $$ {E_s} = \frac{P}{{v\delta }}\left( {J/c{m^2}} \right) $$ (5.1) where P is the incident laser power (Watts), v, the

Automatic Laser Control System for Selective Laser Sintering

IEEE Transactions on Industrial Informatics, 2019
The quality of SLS products is dramatically degraded by excessive temperature gradients in the thermal profile of the powder bed. Thermal gradients in the presintering temperature, which is defined as powder temperature before laser scans, are inevitable in commercial SLS machines due to various reasons.

Selective Laser Sintering of PEEK

CIRP Annals, 2007
Abstract Polyetheretherketone (PEEK) is a good choice especially for manufacturing medical instruments or implants. These parts are typically produced by conventional manufacturing methods, like injection moulding. Selective Laser Sintering (SLS) could offer more flexibility.

Selective laser sintering of porcelain

Journal of the European Ceramic Society, 2018
Abstract Selective Laser Sintering (SLS) technique is used to fabricate 3D porcelain products with complex shapes. Commercial powder has been studied and optimized in terms of morphology and particle size distribution in order to get a perfect powder layerwise which remains the critical step of such a technique. The influence of laser energy density (

Selective Laser Sintering of Zirconia

MRS Proceedings, 2000
AbstractA combination of Selective Laser Sintering and colloidal infiltration has been used to create partially stabilized zirconia molds for titanium casting. The mold material system was chosen for its low reactivity with molten titanium and thermal shock resistance.
