Lussenburg, K.M. (author)
Additive manufacturing, or 3D printing, offers a new paradigm for the way functional products are designed, manufactured, and assembled. Its additive nature provides the ability to create complex-shaped parts, without an increase in production time or costs, which would be difficult to produce with conventional manufacturing. In addition,...

Additively manufacturing can bring opportunities and risk factors to the aerospace industry. On one hand, additive manufacturing allows the manufacturing of structures with geometries that are difficult or impossible to fabricatewith conventional machining procedures. This geometry flexibility may lead to components with a greater strength-to...

Self-healing concrete has great potential to enhance the durability of concrete structures without significantly increasing the initial costs. Among the self-healing approaches, vascular self-healing cementitious composite is capable of supplying healing agents to the cracked region in a continuous way or multiple times. However, the use of...

Shape memory alloys (SMAs), such as nickel-titanium (NiTi) alloys or Nitinol, possess remarkable properties, including superelasticity and shape memory effects, which are attributed to the reversible martensitic transformation. However, traditional manufacturing of NiTi SMAs is challenging due to its high ductility and reactivity, which limits...

The world has seen industrial revolutions with advancements in manufacturing technologies. The advancements in Additive Manufacturing (AM) technologies will bring another revolution sooner rather than later. Nowadays, the Wire and Arc Additive Manufacturing (WAAM) process is already used to manufacture large-scale structures such as ship...

With the advent of Additive Manufacturing (AM) techniques, the design principle of `form follows function' no longer remains a utopian proposition. The unprecedented design freedom offered by AM is making it possible to conceptualize highly performant designs by efficiently leveraging geometrical complexity. The increase in design freedom...

The treatment of largy bone defect remains challenging in clinics. All the clinically available bone grafts have their own limitations and are not ideal for the treatment. Therefore, developing a new generation of suitable bone substitutes is urgently needed. In the recent years, porous magnesium (Mg) has been extensively studied for orthopedic...

The treatment of large bone injuries continues to be challenging partially due to the limited quantity and quality of bone-replacing materials. Iron (Fe) and its alloys have been developed as a group of load-bearing biomaterials. Recent advances in additive manufacturing (AM) have enhanced the potential of Fe-based biomaterials as biodegradable...

The products in our day to day lives have different requirements in different regions of the product. One way of dealing with such spatially varying requirements is to divide the product into multiple parts and assign each part a different material. For example, the handle of a drill is often fitted with a rubbery material which gives it more...

The growing demand for manufactured products with complex geometries requiring advanced fusion-based manufacturing techniques emphasises the importance of process development and optimisation to reduce the risk of adverse outcomes, which is currently impeded with traditional approaches (trial and error experiments). Development, optimisation and...

Since the beginning of time, humans have been trying to replace the skeletal system in cases of trauma or disease. Medical devices were designed, manufactured, and implanted, to restore the function of the skeletal system. Fast forward to today and joint replacements are among the most common surgeries carried out in the world. Despite their...

Oxide dispersion strengthened (ODS) steels are promising candidates for use as structural materials in the next generation fission and fusion reactors. Compared to conventional ferritic or martensitic steels, ODS steels exhibit improved high-temperature creep properties and irradiation resistance. Favourable properties are mainly attributed to...

van de Ven, E.A. (author)
This thesis a method is described to include manufacturing constraints of the additive manufacturing process into topology optimization. Topology optimization often results in complex structures, which can only be produced by additive manufacturing. Although additive manufacturing has much fewer design restrictions compared to conventional...

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...
