4D Printing: Post-processing for the masses

This research investigates the challenges a user faces in the activation step in shape-changing products. First, previous research on the topic of 4DP is reviewed and important factors are described. Namely, activation temperature, print temperature, print speed, and layer height have a signifi cant impact on the shrinkage...

Fluidic Control: Tangible control mechanisms for multi-material fluidic driven interfaces with material jetting additive manufacturing

Fluidic interfaces use liquids to sense, compute, and output a dynamic appearance or behavior in response to mechanical deformation inputs.<br/>Integrating logic and user-actuated control mechanisms in the interfaces can, in the future, enable to achieve more complex dynamic behaviors for designing interactive artifacts that are entirely analog...

The Bits That Matter: A Bone Remodelling Approach For Biphasic Metamaterial Optimisation

The widespread proliferation of cellular lattices in engineering design has entailed a revolution in the design of lightweight and multifunctional structures. Furthermore, the development of auxetic metamaterials has led to applications in fields ranging from biomedical to civil engineering. However, cellular lattices suffer from the development...

The research is aiming at new ways of applying 3D printing fabrication techniques to develop easily applicable sensing structures to...

Designing Magnetic Soft Materials for 4D Printing

Magnetic soft materials are a newly developed material that can transform into programmed shapes when it is placed in an external magnetic field. It is made out of silicone with embedded magnetic particles that lay in magnetization patterns due to 3D printing them under a magnetic field. Its characteristics are fast, remotely controlled,...

3D printing living materials: Optimizing the longevity and photosynthetic ability of microalgae structures

This graduation report aimed to improve the mechanical properties of a sustainable 3D print material made of microalgae, in order to create an macro-porous 3D structure with enhanced longevity and photosynthetic activity. This research builds upon the alginate based bio-ink from Balasubramanian et al (2021). Their material proposal lacked...

Designing personal respiratory protection equipment during a crisis situation

This project contains the graduation project of Fokke Jongerden as part of his curriculum of the master Integrated Product Design at the TU Delft. The project consists of a reflection and redesign of the Air-Wave.org Protector (AWP), a respiratory protection device designed by the non profit Air-Wave.org. The AWP is developed to protect hospital...

Custom Mouthpieces for Dental Care: Design for manufacturing of custom toothbrush mouthpieces

This thesis covers the design, implementation, and manufacturing methodology of a custom mouthpiece for the automatic toothbrush in development by Dental Robotics. The results are a proof-of-concept digital processing pipeline, a functional prototype, an evaluation of custom mouthpiece efficacy relative to the standard mouthpiece, and a...
