Exhibitors for show

Coherent will showcase its Meta laser machine tool, a small form factor yet flexible CO2 based laser system for cutting and engraving. Available in 150W, 250W, 400W and 1,000W power levels and inclusive of both CAM and HMI software, the Meta family delivers productive performance for a broad variety of applications.

These machines are useful tools in R&D labs, universities, job shops, and production facilities. The CO2 laser enables the easy set up of jobs to cut and engrave: metals including stainless steel, mild steel and aluminium; non-metals such as acrylic, wood, plastics, and gasket materials; and films such as bio-medical substrates.

The BeamSquared system being shown by Ophir-Spiricon is a compact, fully automated tool for measuring laser beam quality (M2). The system is based on the company's Ultracal baseline correction algorithm that helped establish the ISO 11146-3 standard for beam measurement accuracy.

BeamSquared delivers accuracy, robustness, and reliability for continuous-use applications in manufacturing, science, and R&D. The system measures the propagation characteristics of CW and pulsed lasers, from UV and NIR to telecom wavelengths in automated mode in less than one minute. Manual mode is available for CO2 lasers and wavelengths greater than NIR, including terahertz. Measurements include waist diameters, full angle divergence, waist locations, Rayleigh lengths, M2 or K and BPP factors, astigmatism, and asymmetry.

Plasmo, a provider of quality assurance for additive manufacturing, will be showing its Fastprocessobserver, a photodiode-based measurement system. The device detects the light generated when the metal is melted, and this takes place laterally and coaxially. The measured values, in conjunction with further machine and process parameters, form the basis for monitoring the welding process. Evaluation of the data is carried out by means of specially developed algorithms in real-time.

For serial applications of additive manufacturing, such as those for medical technology and aviation, Plasmo has created prerequisites for the implementation of suitable quality assurance systems.

RPM Innovations will be exhibiting the RPMI 557 laser system, a metal additive manufacturing machine that incorporates laser deposition technology. The rapid solidification of the melt pool it offers provides excellent material properties and precise placement, allowing it to freeform parts directly from CAD models, repair metal components typically considered non-repairable by conventional techniques, or strategically add features to forgings or castings.

The RPMI 557 system has five axes and is atmosphere controlled, with a work area of 5ft (1,524mm) in X and Y, and 7ft (2,133mm) in Z. It also includes a tilt and rotate table.

RPMI also manufactures a 535 model (five-axis system) and a 222 model (four-axis system).
