Additive manufacturing (also known as 3D-printing) is a class of manufacturing technologies that adds material layer by layer to create a product.
Its main advantages are the ability to generate geometrical forms with few or no restrictions, to produce items at low scale since it operates free of tooling constraints. It is increasingly used for medical applications, in aerospace, in product development in general, and more recently, in mainstream manufacturing.
Current research by Matthias Holweg, Professor of Operations Management, focusses on the economic foundations of additive manufacturing. This in turns determines how this technology can be applied in manufacturing.
Other research focuses on the integration of additive manufacturing into tool-based manufacturing systems, and the use of 3D-printing to enable a circular economy.
