Design of a 3D printed steerable bipolar electrosurgical tool

Current electrosurgical instruments often lack the capability to be optimally customized to a certain procedure/patient. It simply wouldn’t be feasible to produce ten or hundred different configurations in terms of dimensions and geometry of the same device. Most instruments come in one configuration. This study aims to increase the flexibility...

Full Color High Definition Fused Filament Fabrication

Although Full Color (FC) High Definition (HD) Additive Manufacturing (AM) machines are available on the market today, a FC HD Fused Filament Fabrication (FFF) printer has yet to enter the competitive FFF market. Leapfrog, a FFF printer manufacturer, holds a patent that allows the application of coating on 3D printed FFF filament after it has...

Concrete in an AM process: Freeform concrete processing

This thesis examines the additive manufacturing (AM) of concrete, its possibilities, feasibility and advantages over existing techniques. The first part generally focuses on the characteristic properties of concrete that are important and how they relate to an AM method, for instance aggregates and reinforcement. After this extensive...

A Knowledge Based System to Support Design for Selective Laser Melting

Modern Computer Aided Design/Engineering can assist in the design of highly optimized engineering structures. Such structures allow for a significant reduction on the strain of resources across the product life cycle, where the potential for weight reduction is most beneficial for the aerospace industry. However, their production is currently...

Printing the printer

The use of AM production techniques will become more and more interesting for Océ. The AM techniques are evolving the precision, repeatability and speed is being researched and will most probably improve over time. But one of the biggest thresholds for AM at Océ at this moment is the UL94 flammability certification, this requirement can...

Automated Embedding of Electronic Components in 3D Printed Products

Embedables is a new concept which invites every designer to start creating simple electronic products, without having to worry about how the electronic part of the product is going to come to life. While working on the CAD model of your product, choose the component you wish to use from the component library and simply drag and drop it at the...
