Interlaminar toughening approaches for additively manufactured liquid crystal polymers

Liquid crystalline polymers have recently attracted attention for their great tensile properties. However, their interlaminar fracture toughness is low. To solve this, toughening approaches inspired by Nature are applied, exploiting the shaping freedom of fused deposition modelling. Three approaches are studied: the matchstick approach, z...

Design of a Super-Compressible Metamaterial: An Experimental Investigation Guided by Machine Learning

Mechanical metamaterials are a new emerging class of materials which achieve properties outside the bounds of conventional materials. A metamaterial consists of a unit cell which is periodically repeated in space. In this study, a new metamaterial unit cell is proposed, derived from a class of space structures known as deployable masts. What...

Intent-Based Material Extrusion 3D Printing: Moving from process-driven to intent-driven 3D printing

The graduation project is carried out as a collaboration between the Delft University of Technology and Ultimaker. Ultimaker B.V. is a 3D printer company located in Geldermalsen, The Netherlands. Users of 3D printers are presented with a multitude of action possibilities. However, these action possibilities are not yet translated into easy to...
