CompoTech announces LaserWay project developments 

CompoTech (Sušice, Czech Republic) has shared the latest developments in its LaserWay project, an initiative meant to advance laser manufacturing technologies for composites manufacturing. 

The project is segmented into three primary subprojects: Laser Blanking, Micro Drilling and Extreme High-Speed Laser Applications (EHLA), with CompoTech playing a pivotal role in the first and third subprojects.

Dr. Robin Poul, analytical design engineer at CompoTech, explains the role of composites in the project. “We are developing a dynamic part of the machine due to the high speed of a laser head. This is related to the mechanical vibration of the structure, and composite materials can help reduce this. As a result, this project aims to create a high dynamic component of the machine, expanding our portfolio of products and solutions. These will be applicable to other industry areas where high dynamics and partial heat resistance are required.”

The LaserWay Project is divided into three modules, each targeting specific advancements in laser technology:

• Module 1: WayFASTER — Aims to enhance the performance of laser manufacturing technologies by developing lightweight machine designs, advanced vibration control techniques and software optimizations tailored for high-speed applications.
• Module 2: WayBETTER — Focuses on improving process robustness and quality through dynamic gap control, beam shaping mechanisms, in-process photonics quality control and optimized process parameters.
• Module 3: WaySTRONGER — Integrates new technologies from Modules 1 and 2 to boost the sustainability, resilience and flexibility of manufacturing processes.

CompoTech’s efforts in the Laser Blanking subproject are focused on enhancing the efficiency and precision of laser cutters. The project aim is to develop the supporting structure and spark arrester that will transform the company’s current LaserStartLine beams, which are already optimized for 8G performance. Key innovations include:

• Spark arrester: Designed as a 50-millimeter-wide groove, this component moves in tandem with the laser head to protect against sparks and dripping metal. CompoTech is experimenting with a geopolymer matrix  for sample production, with testing to be conducted at partner Ideko’s laboratories.
• Supporting structure options: Cylinders on a scissor mechanism moving with the spark arrester; triangular beams with sliding elements; beams with an air intake for aerostatic guidance; carrier belts equipped with moving rollers.

The EHLA subproject is pushing the boundaries of powder metal laser 3D printing, particularly in regards to developing a composite gantry beam for large-scale 3D printing, capable of lengths ranging from 1-5 meters. This innovation will use pitch fibers and undergo rigorous finite element analysis (FEA) in-house and in collaboration with Ideko and RCMT.

CompoTech is collaborating closely with Ideko and RCMT to ensure that its innovations meet the highest standards of efficiency and reliability. RCMT will conduct preliminary tests, with final testing performed at Ideko’s state-of-the-art facilities.
