Exploring High-Precision Non-Assembly Mechanisms: Design of a Vitrectome Mechanism for Eye Surgery

A vitrectome is a commonly used instrument in eye surgery, which is used to cut and aspirate the vitreous body out of the eye. The mechanism of the vitrectome consists of miniature components that need to be assembled by hand due to their size. Non-assembly 3D printing, in which fully functional mechanisms can be produced in a single production...

Broadband Waveguide Characterization of 3D-Printed Anisotropic Dielectric Crystals

Additive manufactured structured dielectrics with engineered permittivity tensors are promising tools for novel microwave components and are drawing increasing attention from researchers. However, design modeling and experimental verification of anisotropic materials are challenging and have not yet been thoroughly explored in the literature. In...

3D Printing of Flow-Inspired Anisotropic Patterns with Liquid Crystalline Polymers

Anisotropic materials formed by living organisms possess remarkable mechanical properties due to their intricate microstructure and directional freedom. In contrast, human-made materials face challenges in achieving similar levels of directionality due to material and manufacturability constraints. To overcome these limitations, an approach...

Discontinuous Long Fibre Reinforced Thermoplastic for Additive Manufacturing

Current large-scale additive manufacturing extruders use short reinforcing fibre-filled thermoplastic pellets, which marginally improve the mechanical performance but are too short to exploit the strength of the fibres fully. Long fibre pellets have much higher potential strength, and the development of higher strength materials could create...

Spin-Printing of Liquid Crystal Polymer into Recyclable and Strong All-Fiber Materials

Fiber-reinforced polymers are widely used as lightweight materials in aircraft, automobiles, wind turbine blades, and sports products. Despite the beneficial weight reduction achieved in such applications, these composites often suffer from poor recyclability and limited geometries. 3D printing of liquid crystal polymers into complex-shaped...

Manufacturing of functionally graded ceramics with in-space resources

Building habitats on the Moon is required for long-duration missions foreseen in the very near future. The availability of lunar regolith will allow to manufacture such in space habitats and reduce the cost of space missions. However, the Moon has specific environmental characteristics that are different compared to terrestrial habitats:...

PET GROWN: A self-sustaining, mono-material and multi-functional green roof module

The built environment is and will be the place in which most of the people live and its expansion is unavoidable due to urbanization. However, such a phenomenon will increase further the already high material consumption in the building industry, as well as the waste generation. A development that rises many concerns in modern society and, thus,...

Additively manufactured biodegradable porous metals

For the treatment of large bony defects, no perfect solution has been yet found, partially due to the unavailability of ideal bone implants. Additively manufactured (AM) biodegradable porous metals provide unprecedented opportunities to fulfil the requirements for ideal bone implants to be used in such treatments. Firstly, the multi-scale...

3D Printing Clay Facade Walls: Integrating Ventilation systems into printing process

Since 3D printing is relatively new in the architecture applications, exploring how it could be integrated with environment-friendly materials as clay could lead to a more sustainable approach for materialising complex building components.<br/>This research is investigating the answer to the research question “What are the printing techniques...

3D Printing for the Fabrication of Biofilm-Based Functional Living Materials

Bacterial biofilms are three-dimensional networks of cells entangled in a self-generated extracellular polymeric matrix composed of proteins, lipids, polysaccharides, and nucleic acids. Biofilms can establish themselves on virtually any accessible surface and lead to varying impacts ranging from infectious diseases to degradation of toxic...

Wire and Arc Additive Manufacturing of Manganese Aluminium Bronze: Microstructure control for corrosion resistance

Wire and Arc based Additive Manufacturing (WAAM) processes are novel technologies that are seen as promising candidates for fabricating complex 3-Dimensional large scale components. These processes offer avenues to locally tailor metallurgy of the melt pool and thus produce functionally and compositionally graded components for improved...

The structural feasibility of 3D-printing houses using printable polymers

At this point in time, 3D-printing techniques in general, but especially applied for the building industry, still are in a phase of early experiments. One of the experimental attempts is to print a full-scale, three-story high, house in Amsterdam, using an up scaled version of a FDM-printer that is able to print blocks of 1.8 x 1.8 x 3.0 meters...
