Print Quality Optimisation of Upcycled Biomaterials for Ambient 3D printing

With growing concern over our reliance on non-renewable resources and the environmental impact of conventional manufacturing, the quest for sustainable materials and production processes has intensified. This pursuit has extended to the field of additive manufacturing, where bio-materials have emerged as promising alternatives, aiming to reduce...

Material Jetting: Exploration on mixtures of solid and liquid for shock absorption

This research project delves into the potentials of material jetting printing through an exploration of voxel printing techniques that integrate solids and liquids. The focus centers on assessing the shock absorption (SA) capabilities of diverse samples incorporating varying materials and printing patterns. The key materials employed in this...

Modular Saddle System for female cyclists

Selecting the perfect cycling saddle can be a long and painful process trying and buying multiple saddles. Riding on the wrong type of saddle can cause various irritations and can even result in erectile dysfunction (Goldstein, 2007) and may in the end spoil the fun of cycling.<br/><br/>A direction in the design of female saddles was chosen...

3D printing for Frugal Innovation in Kenya: the design of a hand grip tool

This thesis is concerned with exploring just how to develop products in line with this frugal methodology through the case study of a hand exerciser. This main research question for this design project asks to what extent can FDM 3D printing be applied to assist Kenyan occupational therapists in the provision of therapy to individuals with hand...

Repairability of lattice structure in a circular economy: Mechanical response of 3D printed octet-truss lattice structures under quasi-static loading

Repair and maintenance of products require few resources in a circular economy, minimising the environmental impact of manufacturing and use of products. Although lightweight lattice structures have been widely investigated in various fields owing to their advantages in terms of their mechanical characteristics and the development of additive...

Enhancing 3D printing for repair: Designing a system that enhances the collaboration between repairers and makers

This project focuses on enhancing the accessibility of 3D printing for repairers by designing a system in which repairers can collaborate with makers. Repair has become rare in societies with an abundance of cheap goods. However in recent years repair is making a gradual comeback in western culture. Citizen repair initiatives such as Repair...

Design of a new personalized dental implant and its surgical procedure

Dental implants are used to replace missing teeth. Replacing teeth is required, since neighboring teeth can move and reposition in undesired positions if there is an empty space. A dental implant consists of three parts, a dental prosthetic (crown), an abutment and the implant which is fixated in the bone. <br/><br/>Dental implants are placed...

Utilising additive manufacturing techniques to simplify the accordion production process

This thesis focuses on the utilisation of additive manufacturing (AM) technologies for the production of accordions. The goal is to reduce the man hours required in the production and repair of the instrument. The client, Pigini Nederland, currently produces a small accordion for children and adults: the MiniMouse. This instrument is sold for...

Prosthetic Socket Design for Fused Deposition Modeling

This graduation project was started on the observation that most orthopaedic companies seem to be still far away from producing 3D printed sockets for customers. Research into manual and digital manufacturing methods resulted in an overview of the possibilities for integrating digital tools into the socket production process. Together with the...
