Layer Contour Verification in Additive Manufacturing by Means of Commercial Flatbed Scanners

Towards Security of Additive Layer Manufacturing

Additive Layer Manufacturing (ALM), also broadly known as 3D printing, is a new technology to produce 3D objects. As an opposite approach to the conventional subtractive manufacturing process, 3D objects are created by adding thin material layers over layers. Until recently, they have been used, mainly, for plastic models. However, the technology has evolved making it possible to use high-quali...

Photo Repair and 3D Structure from Flatbed Scanners

We introduce a technique that allows 3D information to be captured from a conventional flatbed scanner. The technique requires no hardware modification and allows untrained users to easily capture 3D datasets. Once captured, these datasets can be used for interactive relighting and enhancement of surface detail on physical objects. We have also found that the method can be used to scan and repa...

Application of Additive Manufacturing in Marine Industry

The advantage of additive manufacturing (AM) (e.g. reasonable time and expense in prototyping, and reliable product) has triggered the idea of using this method in manufacturing of marine vessels components. The current article tries to introduce basic concepts of AM method and its application in marine industry; have a glance at additive-manufactured parts microstructure; elaborate the challen...
