Automated In-Situ Placing of Metal Components Into 3D Printed FFF Objects

Visual perception of 3D printed translucent objects

In order to reproduce translucent objects by 3D printers employing fully transparent (or clear) material, modeling the human visual perception of translucency is crucial. In this preliminary study, a set of 256 texture-less samples was created by mixing white and clear materials using multi-jet 3D printing. The samples differ in both lateral light transport properties and transmittance. Two psy...

Active learning in the lecture theatre using 3D printed objects

The ability to conceptualize 3D shapes is central to understanding biological processes. The concept that the structure of a biological molecule leads to function is a core principle of the biochemical field. Visualisation of biological molecules often involves vocal explanations or the use of two dimensional slides and video presentations. A deeper understanding of these molecules can however ...

Automated Architectural Transformation: Objects to Components

Changing an existing software architecture is difficult and painful. The typical result is either a poor adaptation to the target architecture or a substantial debasement of the original. Software generators can simplify the transformation process and relieve the pain for certain architectures. We present a component generator that transforms an object-oriented specification to a component-base...

Simulating the generation of 3D printed micro-objects

Segmenting 3D Objects into Geons

We propose a new approach to 3D object segmentation and description. Beginning with multiview range images of a 3D object, we segment the object into parts at deep surface concavities. Motivated by physics, we detect these concavities by locating surface points where the simulated electrical charge density achieves a local minimum. The individual parts are then described by parametric geons. Th...
