3D-Printed Polyurethane Tissue-Engineering Scaffold with Hierarchical Microcellular Foam Structure and Antibacterial Properties

Shuai Zhang et al.

Summary: This work proposes a facile fabrication strategy of polyurethane tissue-engineering scaffold with hierarchical structure using 3D printing and supercritical microcellular foaming. The microcellular foamed TPU scaffold exhibited enhanced cell adhesion and antibacterial properties compared to the unfoamed scaffold. The strategy offers a way for designing and manufacturing polymer tissue-engineering scaffolds with hierarchical structure and good antibacterial property.

In Situ Foam 3D Printing of Microcellular Structures Using Material Extrusion Additive Manufacturing

Karun Kalia et al.

Summary: A facile manufacturing method for in situ foam 3D printing of thermoplastic materials is reported. By incorporating thermally expandable microspheres (TEMs) into the filament, the researchers achieved the in situ foaming during printing, resulting in highly uniform cellular structures. The study also found that the addition of TEM and plasticizer did not significantly affect the critical temperatures of the material, but the foaming process greatly improved its ductility and toughness.

Facile Fabrication of Highly Sensitive Thermoplastic Polyurethane Sensors with Surface- and Interface-Impregnated 3D Conductive Networks

Harini Bhuvaneswari Gunasekaran et al.

Summary: This research aims to develop a practical and scalable flexible 3D printed piezoresistive sensor with low filler content. The graphene suspension is sprayed over each layer during the 3D printing of the sensor, forming a conductive network, and the prepared samples are subjected to foaming to create a low-mass-density sensor. The developed sensor exhibits stable and connected conduction path, excellent electrical resistance, and resistance against harsh conditions, and shows promising sensitivity for monitoring human motion and actions.

Research progress of 3D printing combined with thermoplastic foaming

Bin Sun et al.

Summary: Thermoplastic foam additive manufacturing is a new industry that combines polymer foaming with 3D printing to address the limitations of material availability and monolithic part manufacturing. Designing multifunctional components with additive manufacturing and foaming allows for the creation of lightweight items with differentiated physical properties. Among various methods, in-situ foam 3D printing is an emerging technique that integrates foaming and fused filament fabrication processes, potentially replacing other foaming processes.

Facile one-step method to manufacture polypropylene bead foams with outstanding thermal insulation and mechanical properties via supercritical CO2 extrusion foaming

Pengke Huang et al.

Summary: A novel method for continuous production of expanded polypropylene (EPP) foam beads via supercritical CO2 (scCO2) extrusion foaming coupled with a wind cutting device is developed, and the real-time cell growth and pelletizing processes of the extruded bead foams are revealed for the first time. This method can greatly shorten production time, save energy consumption, and promote structural diversification. In addition, the transformation of foamed beads and the mechanical and thermal insulation properties of the prepared foamed products are also investigated.

Development of microcellular thermoplastic polyurethane honeycombs with tailored elasticity and energy absorption via CO2 foaming

Bin Hu et al.

Summary: In this study, thermoplastic polyurethane (TPU) honeycombs with ordered macrostructure and microcellular lattice structure were fabricated using FDM and solid-state CO2 foaming. The microcellular structure significantly affected the mechanical properties, energy absorption, and elastic recovery behavior of TPU honeycombs, leading to improved performance. The anisotropic characteristics of microcellular TPU honeycombs offer great potential for applications in both low and high stress environments.

Structured fabrics with tunable mechanical properties

Yifan Wang et al.

Summary: The study presents a structured fabric with tunable bending modulus made up of three-dimensional particles arranged into layered chain mails. When pressure is applied at their boundaries, the particles interlock and jam the chain mails, resulting in a dramatic increase in bending resistance. This property is due to the high tensile resistance of the interlocking particles, providing potential for lightweight, tunable and adaptive fabrics for various applications.
