Holistic, Bionic and Disruptive

Components produced by additive manufacturing (AM) are ideally created using processes designed specifically for 3D printing throughout. Under these conditions, generative processes may usefully complement or supersede existing technologies. The current state of affairs is described as follows by one of the Metav’s regular participants, Rainer Lotz, who, as the Managing Director of Renishaw GmbH from Pliezhausen, will be…

Ultrashort Pulse Lasers

Cleaner Cuts for Semiconductor Packaging

The semiconductor packaging industry faces numerous manufacturing challenges in the production of next generation designs for advanced, miniaturized, microelectronic devices. The singulation of multiple circuits produced on a single substrate into individual devices is a standout example of this. In many instances, the cutting requirements for singulation already surpass the capabilities of mechanical cutting. Specific…

Cylinder Lenses for Beam Shaping

In the modern world, lasers are a critical part of so many new technologies. Fields like manufacturing, measurement, medical treatments and scientific research and many more all depend on lasers. The quality of the beam in all of these application areas is crucial and can often be the difference between success and failure. Cylinder lenses are commonly used to shape and manipulate a laser beam and any errors or aberrations…

Laser Structuring

Design and Function for Freeform Surfaces

Anyone who has ever tried to gift‐wrap a ball elegantly will be familiar with the problem: It is not easy to wrap a two‐dimensional structure around a three‐dimensional object without ending up with numerous folds and kinks. The Fraunhofer Institute for Production Technology IPT in Aachen is currently developing a software module which will be capable of transferring functional structures to complex shapes. …

3D Micro‐Printing: A new Era for Med‐Tech Applications

In recent years, 3D printing has attracted increasing attention in many industries. From bioprinting of living organs to engine and airplane components, a variety of 3D printing techniques are already in use today, mainly differentiated by the additive or subtractive manufacturing approach. But what’s the application potentiality in the med‐tech industry with regards to 3D printing at micro‐scale? And how innovative…

Why Beam Analysis is Crucial for Additive Manufacturing

Workpieces that are lightweight, easy building of complicated structures, fast production cycles – the advantages of additive manufacturing are many and appealing. But what started out as an approach for rapid prototyping will soon be used even to produce critical parts for airplanes or space shuttles. As the number of applications grows, so do the technological requirements. This is why it is so important for the…

From Prototype Manufacturing into Commercial Production

Technology from Renishaw is helping Hieta to move metal additive manufacturing (AM) from prototype manufacture into commercial production of its specialist range of heat exchangers. In particular, the recent addition of Renishaw’s RenAM 500M system at the company has enabled manufacturing times and, therefore production costs, to be reduced dramatically.

Everything Under Control

Not only do tools and machines have to be regularly adapted to new requirements in order to keep up with rapid developments in the field of laser micro machining – the software that is used requires continuous improvement and expansion as well. That is why laser system specialist GFH began with the optimization and partial redevelopment of the GL.control software in 2016. This software is used for planning, configuring and…
