The Influence of 3D Printing Methods and Materials on the Response of Printed Symmetric Carbon Supercapacitors

ECS Advances
We compare the electrochemical response and intrinsic limitations of symmetric carbon-based supercapacitors using two 3D-printing techniques, vat polymerization (Vat-P) and fused deposition modelling (FDM).

Graded Metallopolymer Structures with Shape‐Memory Abilities via DLP‐Based 3D‐Printing

Advanced Functional Materials, EarlyView.
This study presents the digital light processing (DLP) based 3D printing of graded metallopolymers featuring shape‐memory abilities. The permanent shape can be recovered in two distinct steps with excellent rates. The obtained graded prints range from simple rod‐like structures to complex hollow materials.

Development of a Human Recombinant Collagen for Vat Polymerization‐Based Bioprinting

Biotechnology Journal
ABSTRACTIn light‐based 3D‐bioprinting, gelatin methacrylate (GelMA) is one of the most widely used materials, as it supports cell attachment, and shows good biocompatibility and degradability in vivo. However, as an animal‐derived material, it also causes safety concerns when used in medical applications.

Deciphering the Photopolymerization‐Induced Nanostructures and Interface Formation for Submicrometer Additive Manufacturing

Advanced Functional Materials, EarlyView.
This work reveals the UV‐curing‐induced monomer‐rich domain, oligomer‐rich domain, and entangled oligomer domain. The cured submicron films in stressed state induce interlayer nano‐wrinkle structures during the deposition of the second layer. Stress‐free cured films in relaxed state form non‐diffusive, diffusive and semi‐diffusive interlayer ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

Advanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...
