Design of a Circular Product-Service System for 3D Printed Children's Footwear

3D printing technology is a rapidly growing field in the context of footwear production, and in combination with computational design and foot scanning tools and algorithms, this allows for a shift from mass production to mass customization of footwear. This thesis considers the design of a new circular product-service system for children’s...

InfoPrint: Embedding Interactive Information in 3D Prints Using Low-Cost Readily-Available Printers and Materials

We present a fully-printable method to embed interactive information inside 3D printed objects. The information is invisible to the human eye and can be read using thermal imaging after temperature transfer through interaction with the objects. Prior methods either modify the surface appearance, require customized devices or not commonly used...

Patient-specific Ti dental implants with antimicrobial properties

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...

Development of a 3D printed hydraulic piston-cylinder system

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...

Automatic Measurement of The Human Upper Limb Dimensions for Prosthetic Socket: The Multiple Statistical Shape Model Approach

An upper limb prosthesis, i.e. a hand prosthesis, is a device to replace the function of an upper limb on upper limb amputees. In developing countries, amputees’ access to the device is scarce to unavailable. In addition to the absence of experts in those areas, currently there are no automatic measurement methods for upper limb amputees...

Hands can: Determining the location and range of motion of digital joints in 3D scans

The versatility of the hands is revealed in its movements, but often not noticed before trauma occurs. Joint range of motion is used as a measure to follow the progress of diseases. A digital workflow for 3D data in medical appliances is envisioned for years.<br/>The aim of this research is to develop a method that reliably and reproducability...

Methodology and Tools for Testing, Numerical Analysis and Design of the 3D Printed Moulds

The large-scale 3D printing technology created by a group of partners led by DUS Architects allows fabricating components made of thermoplastic polymers with Fused Deposition Modelling technique. These components can be used as moulds for concrete elements, providing freedom of form and unprecedented optimization opportunities. In this report...

Footprint - Custom footwear through digital fabrication methods

A strategic opportunity for the production of footwear through digital fabrication methods was observed when a connection was made between Jan Jansen and MakeMe LAB. And an assignment for a graduation project was formulated. Over the course of the project, some far-reaching changes occurred in the composition of the companies involved. The...
