PRODUCT UPDATE LASER SYSTEMS EOS P 500 polymer AM system
EOS has introduced its EOS P 500 system for additive manufacturing (AM). The machine
can mass produce polymer parts while achieving premium part quality. The new system offers high efficiency for the low
cost-per-part and can process polymer materials requiring operating temperatures of up to 300°C. The EOS P 500 also builds twice as quickly as EOS’s current fastest laser sintering machine, thanks to a dual-laser setup fusing the powder, and a new recoater.
In contrast to previous systems, the EOS P 500
preheats polymer material before it is applied on the build platform, reducing layer times. The system can also reuse all recycled powder for the next build job at higher fill rates, further increasing efficiency. The system offers industrial quality assurance through sensory, as well as camera-based (optical
Rotary axis for tube processing
Bystronic has released a rotary axis for processing tubes on its ByStar Fiber flatbed laser cutting machine, which offers up to 10kW of fibre laser power. The new equipment enables users to switch between sheet and tube processing in a few simple steps. The rotary axis, together with a retractable tailstock, enables tubes from 30mm to 315mm in diameter and in a variety of lengths to be machined. The operator inserts the tube either from the outside through a hatch in the ByStar Fiber’s housing or directly into the machining area through the sliding door along the side. For manipulating longer tubes, Bystronic also offers a rotary axis box, akin to a bar magazine
LS5 and LC5 for sheet and tube machining
BLM Group’s LS5 and LC5 laser systems for sheet and tube processing feature
integrated electronic components aboard the machines that reduce footprint and installation time. The two systems are both ergonomic, easy to use, modular and versatile, with a range of optional modules. The systems are interconnected and capable of interfacing with other machines and with the production management system of Industry 4.0. Multiple versions of the LS5 and LC5 are available for sheet cutting, from 1.5 x 3 metres to 2 x 6 metres, with the possibility of fitting longitudinal or transversal pallet changer systems. The LC5 also works with tubes up to 120mm in diameter. Starting from tube bundles, the system automatically loads and processes each

and thermal) data evaluation, for example stating residual oxygen levels or the temperature of the build chamber. This industrial-grade connectivity before, during and after the AM build process is essential if the EOS P 500 is to be embedded in automated manufacturing environments.

Keopsys PK50 Laser
Components
has announced a new platform for its Keopsys range of pulsed erbium fibre lasers, the PK50. The PK50 gives peak powers up to 15kW and pulse durations of 1ns to 200ns, with pulse repetition rates from 10Hz to 1MHz. A diffraction- limited beam makes these lasers particularly suitable for applications like 3D scanning, where beam quality is crucial.
on a lathe. The detachable accessory is mounted on wheels and tubes up to three metres long can be fed in through the hatch in the machine housing. With an additional extension box, tubes up to six metres can be processed. A tube cutting software module is also supplied, which is an expansion to the BySoft 7 programming software. It allows users to design parts for tube processing, input existing CAD files, edit them and generate cutting plans.

The PK50 has also been developed for applications demanding high reliability and operation in harsh environments. The number of critical components has been reduced to increase the lifetime and provide a reliable rugged device. The square form factor (120 x 120 x 27mm) enables easy integration into a range of systems. Integrated harmonic generation to give green and UV wavelengths is optional.

TEST AND MEASUREMENT Ophir Beam Watch AM
MKS Instruments has introduced the
Ophir Beam Watch AM, a non-contact laser beam monitoring system for additive
piece and unloads the finished parts. The tube processing module and the sheet processing part are mutually autonomous, sharing just the laser cutting head. The tube processing module also has its own operator panel, which controls the entire system during tube processing. The LS5 and the LC5 are available with CO2 laser sources of power up to 4.5kW, or fibre laser sources up to 6kW in power.

manufacturing. Beam Watch AM is a lightweight, compact system designed for real-time measurement of focal shift during laser startup of powder bed fusion manufacturing processes. It measures key beam size, position, and quality parameters, including focus spot size and beam caustic. These measurements mean users can determine when the beam is aligned and in focus, providing more consistent metallurgy. Measurements can be displayed as tabular, 2D, and 3D views, providing a quick and realistic display of laser characteristics. Beam Watch AM is the next generation of the company’s laser beam monitoring systems, all of which use Rayleigh scatter to image the beam without contacting the laser. This removes the potential for damage to the laser and speeds the measurement process by up to two minutes. Beam Watch AM can measure laser powers to 1kW in-situ at rates up to 14Hz, and can handle up to 120kJ without cooling.
