This paper reviews the state-of-the-art of an important, rapidly emerging, manufacturing technology that is alternatively called additive manufacturing (AM), direct digital manufacturing, free form fabrication, or 3D printing, etc. A broad contextual overview of metallic AM is provided. AM has the potential to revolutionize the global parts manufacturing and logistics landscape. It enables dist...

During the last decade, additive manufacturing has become increasingly popular for rapid prototyping, but has remained relatively marginal beyond the scope of prototyping when it comes to applications with tight tolerance specifications, such as in aerospace. Despite a strong desire to supplant many aerospace structures with printed builds, additive manufacturing has largely remained limited to...

Additive manufacturing (AM) has the potential to create geometrically complex parts that require a high degree of customization, using less material and producing less waste. Recent studies have shown that AM can be an economically viable option for use by the industry, yet there are some inherent challenges associated with AM for wider acceptance. The lack of standards in AM impedes its use fo...

A test artifact, intended for standardization, is proposed for the purpose of evaluating the performance of additive manufacturing (AM) systems. A thorough analysis of previously proposed AM test artifacts as well as experience with machining test artifacts have inspired the design of the proposed test artifact. This new artifact is designed to provide a characterization of the capabilities and...

During the last decade, the development in metallic material additive manufacturing (formerly also known as Rapid Manufacturing, RM or Rapid Tooling, RT) has brought this technology from niche applications and short run tooling to be a competitive method capable of producing complex geometries in industrial grade materials, such as for example injection moulding tool inserts with integrated con...

Rapid Prototyping has transitioned from only being able to produce delicate prototypes to being capable of producing robust production parts. As part of this transition, it has been renamed Additive Manufacturing (AM). As a true manufacturing technology, it has become important to deliberately design parts for Additive Manufacturing, and research has begun in how best to achieve this. This thes...
