Abstract:
High performance communications, sensing and computing systems are growing exponentially as modern life continues to rely more and more on technology. One of the factors that are currently limiting computing and transmission speeds are copper wire interconnects between devices. Optical fiber interconnects would greatly increase the speed of today’s electronic devices. In this study it has been demonstrated that by using a new Direct Print Additive Manufacturing (DPAM) process of Fused Deposition Modeling (FDM) of plastic and micro-dispensin

Byggbranschen är alltid i förändring och sättet att bygga utvecklas ständigt inom byggbranschen. Att bygga enfamiljshus idag krävs det mycket arbete och byggbranschen kritiseras ofta när det gäller hastighet som behövs för nybyggnationer. Byggbranschen behöver därför en ny metod och kanske kan 3D-printing vara en alternativ lösning i framtiden. Detta examensarbete syftar därför till att undersöka om det finns möjligheter att kunna bygga enfamiljshus i Sverige med hjälp av 3D-printing.

The area of this work is a combination of draping and printing. It strives towards the technique that dazzles the eye with illusions of more than one dimension. As a viewer you will believe that the prints are real drapings while they are flat surfaces. Today prints in fashion are categorized as placed prints or all-over prints, and generally created as a flat surface to decorate the garments. In this work the idea is to manipulate and challenge the boundaries of print and give it life through the body shapes and in the movement.

This dissertation focuses on developing 3D printing as a fabrication method for microfluidic devices. Specifically, I concentrate on the 3D printing approach known as Digital Light Processing stereolithography (DLP-SLA) in which serially projected images are used to sequentially photopolymerize layers to build a microfluidic device. The motivation for this work is to explore a much faster alternative to cleanroom-based microfabrication that additionally offers the opportunity to densely integrate microfluidic elements in compact 3D layouts for dramatic device volume reduction.

The printing has been performed in a lab environment with focus on high resolution, with less than 10 micrometers in fibre size. Glass capillaries with an inner diameter of 3-10 micrometers were used as nozzles. Three-dimensional structures with a height of 100 micrometers and a fibre

Abstract:
La micro extrusion (ou DIW) est une technique de fabrication additive basée sur le dépôt continu de filaments couche par couche. Utilisée pour l'impression de structures poreuses, le DIW de céramiques denses et résistantes reste un défi. L'avantage du DIW réside dans sa capacité à produire des composites, offrant la possibilité de combiner la mise en forme complexe à un contrôle microstructural et fonctionnel précis de matériaux bioinspirés par exemple.Notre travail se concentre sur l'utilisation de gels de boehmite, un précurseur d'Al2O3, en tant que matrice céramique pour obtenir différentes

The purpose of this project was to develop a 3D printer that can print multiple durometers, or hardness, within one printed part. This project was created by Raytheon so they could develop anti-vibration housings for their electronic components that experience vibrations during flight. Team 16077 was successful in developing a printer. To achieve the result, the hardware and software of a commercial 3D printer were modified. The entire existing extrusion system was replaced with a dual extruder system with a tubing design to be able to extrude multiple filaments (a soft and a hard filament) at

L’architettura nei suoi svariati settori di studio è sempre stata strettamente influenzata dalle innovazioni tecnologiche che ogni periodo storico ha presentato. All'inizio degli anni Ottanta questo sviluppo ha portato un salto da un approccio “analogico” ad approccio “digitale”. La modellazione tridimensionale ha conquistato una posizione importante nel mondo dell’architettura, sia come sostegno nella progettazione e produzione di edifici ex-novo che nel supporto per l’analisi e gestione dei manufatti esistenti. Lo sviluppo della modellazione tridimensionale ha trainato con se lo sviluppo

Abstract:
Supercapacitors, also known as electrochemical capacitors, have shown great potential as energy storage devices; and 3D printing likewise as a manufacturing technique. This research progressively investigates combining these two technologies to fabricate 3D-printed, electrochemical double-layer capacitors (EDLCs). Small EDLCs were designed in a sandwich structure with an FDM-printed plastic frame and carbon electrodes. Inkjet printing was initially combined with FDM printing to produce a pilot sample with a silver ink current collector, however this performed poorly (Cs = 6 mF/g). Henceforth a

Nowadays, manufacturing technologies become more and more aware of efficiency and sustainability. One of them is the so called 3D printing. While 3D printing is often linked to plastic, the truth is there are many other materials that are being tested which could have several improvements over plastics.One of these options is stone or concrete, which is more suitable the architecture and artistic fields. However, due to its nature, this new technology involves the use of new techniques when compared to the more commonly used 3D printers. This implies that it could interesting to know how much

Indiana University-Purdue University Indianapolis (IUPUI)<br>Ceramics have been extensively used in aerospace, automotive, medical, and energy industries due to their unique combination of mechanical, thermal, and chemical properties. The objective of this thesis is to develop an extrusion based ceramic 3D printing process to digitally produce a casting mold. To achieve the objective, an in-house designed ceramic 3D printer was developed by converting a filament based plastic 3D printer. For mold making applications, zircon was selected because it is an ultra-high temperature ceramic with high
