A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Three‐Dimensional Printing Simulator for Endoscopic Adenoidectomy Training

OTO Open
This article presents an innovative approach to adenoidectomy training through the development of a 3‐dimensional (3D) printing model, termed e‐A.L.Ex (endoscopic‐adenoidectomy learning experience).

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

Advanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Instability of the printing jet during the three-dimensional-printing process

Journal of Low Frequency Noise, Vibration and Active Control, 2021
Euler’s instability criterion is widely used in engineering to design a column. However, this criterion is not suitable for judging the instability of a three-dimensional printing process because the axial motion of the printing jet has to be considered.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Three-Dimensional (3D) Printing in Orthopedics Education

Journal of Long-Term Effects of Medical Implants, 2020
Three-dimensional (3D) printing is a newly established concept in orthopedics compared with other industries. Surgical applications of 3D printing and tissue engineering have been investigated since the early 2000s, almost two decades after Charles Hull had patented the first device currently in use for additive manufacturing, also known as rapid ...

Application of Three-Dimensional Technology for the Preoperative Evaluation of Retroperitoneal Tumors

IEEE Access, 2019
With the development of computer medical imaging technology, three-dimensional technology has been gradually applied in medicine. We try to investigate the application value of 3D technology in the preoperative evaluation of retroperitoneal tumors.

Perceptual Translucency in 3D Printing Using Surface Texture

Journal of Imaging, 2023
We propose a method of reproducing perceptual translucency in three-dimensional printing. In contrast to most conventional methods, which reproduce the physical properties of translucency, we focus on the perceptual aspects of translucency.

Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

Advanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.
