Novel room temperature welding method for hermetic packaging
Ville Hevonkorpi, Primoceler
furniture, railway construction and so on. Te solutions proposed by the BLM Group with automatic integration between its Laser Tube laser cutting systems and systems for bending and forming, allow for innovation within the production process. Te ‘all-in-one’ technology enables immediate accuracy and repeatability, without waste and in a flexible manner. Users can produce lots of parts – small, medium and large – in an automatic way, keeping costs down. Te introduction of tubular elements or complete frames made with these technologies, allows a considerable reduction in costs due to the elimination of waste, non-conformity, the increase in accuracy and reducing the cost and complexity of the fixturing.

Te lasers of the Atlantic series are high-power high-repetition-rate picosecond lasers which were designed by EKSPLA to meet demands of the growing market of industrial material processing. Te most powerful model produces more than 60W of average power at the repetition rate range from 200kHz to 1MHz. Consequently, the output pulse energy reaches 300μJ at the lowest repetition rate. Workshop of Photonics (WOP) supplies a technology platform for scribing transparent materials with these lasers. It offers flexibility of choosing the shape to cut (minimal radius 0.2mm) and high quality of the taper-less edge (Ra<1µm).

Surface functionalisation through laser interference structuring
Prof. Dr Andrés-Fabian Lasagni, Fraunhofer Institute for Material and Beam Technology IWS Dresden
Periodic patterned surfaces can be used to provide unique surface properties in applications, such as biotechnology, surface engineering and photonics. Such periodic patterns can be produced using laser processing tools, showing significant advantages over mechanical methods. On the other hand, the resolution of common used laser based surface structuring methods, like direct laser writing, is generally inversely proportional to the fabrication speed. In this

3D printing and its emerging opportunities
Simon Merkt, Fraunhofer Institute for Laser Technology (ILT)
With Primoceler’s room temperature glass bonding technology you can achieve hermetic sealing with no additive materials. Hermetic glass packages can be used in, for example, implantable active medical devices, optical (CMOS) sensors and devices like WLP micro-optics, and MEMS components packaging. Also components that need to survive in harsh environments, such as in the space industry or avionics, can benefit from this new technology. Te heat-affected zone is not seen, therefore the technology keeps the sensitive components inside the package safe during bonding. Te company’s microfabrication solutions have not only improved manufacturing processes, but also revolutionised microscale bonding of transparent materials and enabled completely new product portfolios and business opportunities in the semiconductor industry and medical technology.

‘All-in-one’ laser tube cutting and bending
Sergio Raso, Adige
Tubes and profiles are helping to improve the quality and competitiveness of products in many sectors such as automotive, aerospace,
3D printing is currently hyped as the manufacturing technology to change the way of manufacturing.
Tis presentation gives an overview about the main process characteristics, market growth and current applications of metallic 3D printing in industry. Shorter lead times, complex geometries, faster innovation cycles and the opportunity to implement new business models are the main advantages of 3D printing technologies. Huge companies such as GE, Siemens and BMW are investigating the capabilities of metallic 3D printing in detail and to bring 3D printing to the next level. Te presentation concludes with a critical feedback on how sustainable 3D printing is and where 3D printing really could change the world of manufacturing.
