Dental implants are used to replace missing teeth. Although the success rate of dental implants is high, complications such as lack of osseointegration and peri-implantitis can occur. In this study a new type of dental implant is designed that mimics the root shape of the to be extracted tooth. These types of implants can be placed directly...

For over a decade the use of bio inspired adhesives have been explored to achieve high reversable attachment on a wide range of surfaces. Based on the fibrillar adhesive toepads of geckos, many patterned adhesives have been produced that are able to form and preserve contact with rigid and smooth substrates. But on other types of surfaces, such...

The management of large acetabular defects remains one of the most challenging aspects of revision total hip arthroplasties. Failure of frequently used acetabular reconstruction components are, among others, caused by the lack of biological fixation, a non-physiological stress distribution and stress-shielding. Attempting to diminish these...

Functionally graded materials (FGMs) represent a new class of materials that consist of graded compositional and microstructural patterns allowing to tailor properties. Additive manufacturing (AM) or more commonly known as 3D-printing offers a paradigm shift in FGMs and engineering design due to its ability to produce components with complex...

Recent findings have highlighted the potential of a 3D-printable high-strength Liquid Crystal Polymer, whose anisotropy can be fostered for topology optimization intents. The mesostructure of a 3D-printed liquid crystal polymer is studied: the observation of interlayer features under the form of regular notches or spiraling patterns swirls is...

In the field of prostheses, significant developments have been accomplished so far in low-cost prosthetic limbs using 3D printing technology. However, when it comes to prosthetic hands, 3D printed prosthetic hands are still limited in their grasping ability, such as the adaptability to the shape of an object and a sufficient pinch force level...

Cartilage repair remains a major challenge and treatment of osteochondral defects generally results in inferior quality fibrous repair tissue. This study aims to elaborate on the work of Korthagen et al. who developed a thermoplastic polyurethane and polyetherketoneketone implant to treat osteochondral defects. Although promising results were...

Introduction: Recently 3D printing has received an increasing attention on the area of actuators. It can provide design freedom allowing complex geometries, as well as customization, among other benefits. However, there is no research on 3D printing of hydraulic piston-cylinder systems. The aim of this article is to check the feasibility of 3D...

Radically new technologies, of which ‘the functionality was new to the market or the price-performance ratio was much better than contemporary products’ (Ortt, 2012), can be both risky and rewarding to develop. The innovation phase is the period from invention of a radically new technology until the first market introduction. This research into...

Microvalves are important flow-control devices in many standalone and integrated microfluidic applications. PDMS-based (Polydimethylsiloxane) pneumatic microvalves are the most commonly used type for research purposes, but they require large peripheral connections and cannot be used for controlling gases due to the high gas permeability of PDMS....

The research phase starts with an extensive literature study. To this end, a research question was drawn up, which reads as follows: What possibilities does Additive Manufacturing (AM) offer in airworthy aircraft part production and in what way can suitable parts be selected and redesigned? The most interesting findings from this literature...

Concrete consumption is one of the major environmental issues of our time. This building material is used twice as much as all the other building materials combined. Furthermore, the United Nations predicts that human global population will reach 10 billion inhabitants by 2050. Correspondingly, it is projected that due to global migration from...

Passive measures to tackle increasing energy demands of modern buildings are aimed to generate energy from the roof or the ground beneath and by improving insulation to isolate indoors and outdoors. The author targets the opaque facade sections of a building to develop an active panel to exchange solar thermal energy with his project THERM...

This research investigates the potential of 3D printed sand moulds for casting structural glass column having optimised cross section. Conventionally, Glass, in architectural industry, has been used in form of sheets (Float glass) due to ease of fabrication of planar sheets, but in last few years, cast glass bricks have been used for creating...

The performance of gun and rocket propellants, which consist of energetic materials, is largely determined by their geometry and composition. Con- ventional production methods limit the performance by putting constraints on both. With additive manufacturing, or 3D-printing, there are signi- cantly fewer geometry constraints and together with the...

The fourth Industrial Revolution stands for the current trends of automation and data exchange in manufacturing technologies - which comes with a considerable amount of opportunities as most manufacturers attempt to stay ahead of the competition. One of the possibilities is the addition of FDM printing - one of the types of additive...

Patients diagnosed with drop foot syndrome experience difficulties creating enough clearance during walking, resulting in stumbling over very small obstacles. An Ankle Foot Orthosis is an orthopaedic aid which limits the plantar flexion of the foot, providing a safe walking gait for the patient. Currently, these AFOs are vacuum formed over a...

Plastic is a material that has greatly improved well being for the masses. However, it also contributes significantly to pollution of the natural environment and depletion of natural resources. So far only a small percentage of plastic is recycled and used for the production of new products. Inferior material quality and the inability to make a...
