Metamaterials at terahertz frequencies offer unique opportunities, but are challenging to fabricate in bulk. We adapt the fabrication procedure for microstructured polymer optical fibers to inexpensively fabricate metamaterials potentially on an industrial scale. We produce polymethylmethacrylate fibers containing ~10 μm diameter indium wires separated by ~100 μm, which exhibit a terahertz plasmonic response.

Femtosecond-laser direct-writing is frequently used to create three-dimensional (3D) patterns in polymers and glasses. However, patterning metals in 3D remains a challenge. We describe a method for fabricating silver nanostructures embedded inside a polymer matrix using a femtosecond laser centered at 800 nm.
FAQs
The digital model is converted into programmed cross-sections that guide the system at successive build levels. For each section, the equipment deposits material, shapes it, or selectively solidifies it, then proceeds to the next layer. This translation from geometry to controlled material placement allows internal and external features to be reproduced without relying on a custom mold.
Material is formed through several controlled actions: deposition places material where required, shaping defines its geometry, and selective solidification hardens chosen regions. The appropriate action depends on the material being processed, such as a polymer, ceramic, hydrogel, or cell-containing material. This distinction affects how accurately the intended structure and composition can be realized.
Architecture, porosity, and material placement are central design variables rather than incidental features. Adjusting them lets researchers tailor a scaffold or construct's mechanical and biological properties to a bioengineering objective. Consequently, two objects with similar outer dimensions can serve different purposes if their internal organization differs, making digital control valuable for regenerative medicine research.
Compared with conventional fabrication, solid freeform fabrication is especially useful when a design contains complex geometries or requires customized internal organization. It can reduce dependence on custom molds and extensive machining because the computer-controlled build follows the digital model directly. The advantage is not simply shape reproduction; it is the ability to coordinate geometry, porosity, and material placement.
A typical workflow begins with a digital model, which is interpreted as programmed cross-sections. The system then builds successive layers by depositing, shaping, or selectively solidifying the chosen material according to those sections. Researchers can use the resulting object as a scaffold, implant, or biological construct, with the final architecture reflecting the programmed geometry and material distribution.
Material choice should match the intended construct and its required properties. The relevant material classes include polymers, ceramics, hydrogels, and cell-containing materials. Selecting among them provides a way to combine the manufacturing process with the desired mechanical or biological behavior, although the appropriate choice depends on the specific scaffold, implant, or biological construct.
In bioengineering, the method supports tissue-engineering scaffolds, medical implants, and customized biological constructs. Its value lies in tailoring both form and internal organization for regenerative medicine and biomedical research. Cell-containing materials extend the approach toward constructs that incorporate biological components, while polymers, ceramics, and hydrogels provide different material platforms for designing the required object.
