  • Hyperspectral imaging for 100%-inspection of surfaces and films

    Press release (Nr. XIV) - Fraunhofer IWS / 4.7.2017

    The hyperspectral imaging technology (HIS) perfectly meets the aspiration “to see more than the eye allows”. This novel camera technology enables to image light not only in a spatial but additionally in spectral resolution. To get dedicated sample information, it is now possible to analyze up to thousand spectral bands whereas formerly only three spectral bands (RGB) could be used. Fraunhofer IWS scientists have developed an integrated HSI solution, which implements the po-tential of the HSI technology into reliable hard- and software. The IWS technolo-gy is highly suitable for applications in the fields of surface and film inspection. Fraunhofer IWS will present the measuring system imanto® obsidian at the tradeshow LASER World of PHOTONICS in Munich.

    Due to digitalized product development and cross-linked manufacturing cycles development periods have been radically shortened. Rapid product change requires from manufacturers and suppliers a high rate of flexibility, so that customized and cost-optimized solutions can be offered. For the development of new laser welding technologies individualized processes tailored for specific materials and products need to be combined with innovative hardware concepts. For the welding of difficult to weld materials a new high frequency beam oscillation welding head with integrated process monitoring – the remoweld®FLEX – has been developed, which is going to be presented at the industrial trade fair LASER World of PHOTONICS in Munich.

    Functionalization of technical surfaces by means of natural, bio-inspired structures is an innovation driver of the 21th century. The functionalities achieved are applicable for e.g. improved bio-compatibility in medical and biotechnological industries, for tribological applications in the automotive industry and for optical applications such as product and brand protection. Fraunhofer IWS has been developing modularly designed solutions for surface functionalization tasks by fabricating micrometer and sub-micrometer structures in a targeted and flexible manner. Scientists of the Fraunhofer IWS will present for the very first time the worldwide most compact system for surface structuring by means of scanner-based direct laser interference patterning at the tradeshow Laser World of Photonics in Munich.

    Confidence and reliability are key criteria for the potential introduction of innovative joining techniques. This is, in particular, also true for the modern maritime industry. Scientists of the Fraunhofer IWS have developed a novel, low heat-input but highly efficient laser welding technology for joining processes of up to 50 mm thick parts made of seawater-resistant aluminum alloys. A decisive advantage of this technology is the comparatively low laser power (< 4 kW) needed during the welding of thick metal sheets. The low laser power enables extraordinarily small weld seam widths and minimal component distortion. The IWS laser multi-pass-narrow-gap welding technology (laser MPNG) has been successfully certificated by the classification society DNV GL and is thus now ready for potential industrial applications.

    Scientists of the Fraunhofer IWS Dresden and the Fraunhofer IFAM Bremen have developed a novel technology for the large area, efficient and environmentally friendly pre-processing of fiber glass metal laminates (GLARE). This new technology has been jointly developed within the framework of the aeronautical research project » AUTOGLARE- advanced metal fuselage construction- fiber glass reinforced aluminum and automated manufacturing processes for high production rates in the aircraft industry; Sub-project NFM-GLARE «. The adhesively bonded multilayer composites, pre-processed by laser, verifiably provide excellent adhesion and corrosion properties so that chemical pre-processing in anodizing bathes are no longer necessary.

    Integrated digitization of processes for laser materials processing provides customers with measurable results in industrial applications. Based on the IWS’ comprehensive systems engineering know-how, cyber-physical laser materials processing systems are being developed by means of new hardware and software solutions. These systems assist the operator in the performance of complex manufacturing tasks, they improve product quality, and they enhance the reproducibility of manufacturing results both for regular and frequently changing production sequences. Research developments for hardening, cutting and joining as well as for additive manufacturing processes will be presented at the Hannover Messe Industrie and at the Laser Messe München.

    Lightweight design is one of the mostly progressive research areas involved in accomplishing the transition from fossil fuels to renewable energy sources, as well as the reduction of CO2 emissions. Innovative materials, such as carbon or glass fiber reinforced plastics (CFRP/GFRP), as well as metal foams, contribute to the successful implementation of the target set by the Federal Government. The Fraunhofer IWS has been researching in this field for many years to provide promising and affordable solutions for our industrial and research partners. One of these solutions is the laser-remote cutting technique.

  • Artificial mini organisms instead of animal testing

    Everyone wants medication – we’re not talking about animal testing here. Up to now, this has been a necessary evil in medical research. Microphysiological systems, in which organs and organ systems are “created” are a promising alternative. Therewith, complex mechanisms of the human body can be realistically analyzed. Among other things, these microsystems contain ducts, reservoirs, actuating elements, sensor technology and 3D scaffols “made by laser”. The Fraunhofer IWS offers partners from the fields of biology and medicine complete solutions for microsystem technology – from design to prototype, including the automation system.

    Dresden researchers of the Fraunhofer IWS and the TU Dresden have developed a new energy-efficient process chain for carbon fiber manufacturing. The approach aims at the conversion of polyacrylonitrile (PAN) procurser fibers by means of their stabilization, carbonization and graphitization. Thereby, in future it will be possible to produce carbon fibers at clearly lower costs.
