Mikroniek September 2023: New Manufacturing Technologies
The September issue of Mikroniek is devoted to the theme of New Manufacturing Technologies. In this editorial, Teun van de Sande, CTO of rising star Wefabricate, defines modern manufacturing as producing smarter, i.e. with awareness of sustainability, adaptability and durability. The theme articles cover, a.o., alignment turning for high-precision optical systems, challenges and opportunities in gradient-index optics, and applications of 3D template-based microfabrication. Other manufacturing features concern shrink compensation for 3D PEEK printing, spatial Atomic Layer Deposition, and precise machining and laser processing of brittle materials. Also included is a report of the euspen Conference 2023. Click here for a first impression. (Cover image courtesy of Horizon Technologies).

2 November DSPE Knowledge Day about ‘Engineering for Cryogenics.’
|
Does cryogenics make you hot!
|
Please be invited to the upcoming DSPE Knowledge Day: Engineering for Cryogenics, which will be held on the 2nd of November at ASTRON Dwingeloo, Netherlands Institute for Radio Astronomy. We are hosted by the NOVA Optical-Infrared group, who develop opto-mechanical cryogenic systems for astronomy.

Design strategies for large range flexure mechanisms.
|
Flexure mechanisms (or elastic elements) use elastic deformation to achieve motion, which results in highly repeatable and lubricant-free systems. A drawback is their limited motion range due to design trade-offs between stress, dynamic/stiffness performance and build volume. In this talk, new strategies to increase this motion range will be presented, including movies of different demonstrators.

Davidson award 2023
The DSPE is going to present the 9th edition of the “Davidson Award” this year, on November 16th at 4:30 pm during the Precision Fair in the Brabanthallen Den Bosch. This award is named after the authority on precision engineering at Philips in the 1950s and 1960s. The DSPE aims to stimulate young talent with this award and therefore is intended for a young precision technologist who:
|
- has been working in the field for 5 to 10 years
- delivers demonstrable performance
- actively or passively propagates their enthusiasm about precision engineering.

Preserving precision in PEEK printing
|
Bond3D’s unique 3D-printing technology has vastly expanded the application scope of PEEK.High-strength, isotropic parts can be produced from this high-performance polymer in a pressure-controlled, voidless printing process. Due to PEEK’s high melt temperature and high coefficient of thermal expansion, thermal effects play a significant role.

Sustainability – ASML adopts a circular economy model
|
ASML has established the House of Re-use. To contribute to a circular economy model, fewer new parts are designed and the re-use of used parts is increased with a goal of more than 95 percent of re-used parts in 2025.

Alignment turning for high-precision optical systems
|
The demand for high-precision optical manufacturing technologies is increasing.This includes the need to align passive optical elements such as single lenses and lens systems as well as active optical elements such as laser diodes. For passive and active optical components, alignment turning meets the increasing industrial requirements for precision, freedom of design, automation, and competitive production times, as described in this Mikroniek article.
