PRODUCT UPDATE LASER SYSTEMS


TruPrint 1000 laser metal fusion machine


Trumpf is expanding its technology and product range in the field of industrial 3D printers. The company has released its TruPrint 1000 laser metal fusion (LMF) machine. The compact model can generate parts 100 x 100mm. All the components are integrated into the compact housing, including the laser, optics, process enclosure, filter unit and control cabinet.


The supply cylinder provides capacity for up to 1.4 litres of stainless steel, tool steel, aluminium or other weldable material in powdered form. The system uses a 200W laser to fuse powder corresponding to the contour of the part, before the construction chamber is lowered and the procedure repeated. At every return to the supply cylinder, a mechanical design tilts the coating mechanism slightly. Thus it can retract relatively quickly, without colliding with the powder bed or the part generated up to that point. Trumpf has also developed a prototype of


the TruPrint 3000. With this larger model, also using LMF technology, parts measuring up to 400 x 300mm can be generated for industrial manufacturing. www.trumpf-laser.com


Al-Rock mobile laser hardening system


TLM Laser has designed the Al-Rock mobile laser hardening system, enabling large and complex automotive tools to be processed in-situ.


The Al-Rock is a mobile robot specifically for laser hardening applications on metal surfaces. Combining the efficiency of a diode laser system with the flexibility and dexterity of a six-axis robot, all mounted to a self-propelled crawling chassis, allows the technology to be taken directly to the press and the laser hardening process to be performed in-situ. This can generate significant cost savings for automotive manufacturers by reducing the time that a press is out of action. Stoppages in a volume production car plant can run into many tens of thousands of pounds per hour. The mobile system can work on press tools at short notice, with minimum downtime and using a hardening process that is also both fast and efficient.


The extensive horizontal reach of the robot HELP laser marking


Foba has developed a laser marking process called HELP (Holistic Enhanced


Laser Process), which enables medical device manufacturers to mark devices according to Unique Device Identifier (UDI) regulations set by the FDA. HELP, developed by Foba for its laser marking machines with integrated vision system IMP (Intelligent Mark Positioning), allows medical device manufacturers to meet FDA identification requirements, while reducing production costs,


makes it possible to cover the large areas and complex shapes normally associated with automotive press tools. The diode laser system and zoom optics allow precision selective hardening to be carried out without the risk of residual heat affecting surrounding areas, with the added benefit of being energy efficient when compared to the traditional induction or flame hardening alternatives.


The system delivers 3,000W of output power, making it possible to case harden to a depth of approximately 2mm, depending upon the material. The process time for selective laser hardening is also extremely short, requiring just a few seconds to heat the area of the part to the required temperature.


Although the system is designed to be mobile, it can also operate as an off-line laser hardening cell. The flexible laser safety guarding package that comes with the system can be used to set up a static workstation. www.tlm-laser.com


minimising waste and improving product quality. Apart from the marking of the medical product itself, HELP offers mark verification prior to marking, and post-mark validation. During the post-mark verification process, the content of 1D and 2D codes – including data matrix codes – can be read directly, which is indispensable for compliance with the new UDI set by the FDA. The UDI regulation relates to marking and identifying medical devices within the healthcare supply chain. www.fobalaser.com
