Here, EE is defined as the ratio between equivalent quality and specific energy consumption (SEC), where SEC refers to the energy consumption per kilogram of part produced during the building process. Asymmetrical laser resonators were adopted to enable a large mode-matching between the lamp pump mode and the fundamental laser mode within each rod. Discussion on future prospects of laser technologies for additive manufacturing will be finally covered. (b) Part fabricated by AM. Three-Dimensional Microfabrication Using Two-Photon Polymerization (TPP) is the first comprehensive guide to TPP microfabrication�essential reading for researchers and engineers in areas where miniaturization of complex structures is key, such as in the optics, microelectronics, and medical device industries. In this report the focus is on the worldwide state of the art for metal AM, with a particular focus on how the situation looks in Sweden. Selective laser sintering or melting (SLS/SLM) techniques are first introduced, followed by analysis of results from silica (SiO 2 ), zirconia (ZrO 2 ) and ceramic-reinforced metal matrix composites processed by direct laser sintering and melting. The results show that the cooling time and cycle time can be reduced more than 50% when molding a plastic product that is difficult to cool by conventional straight-drilled cooling channels. TPP microfabrication attracts increasing attention among researchers and is increasingly employed in a range of industries where miniaturization of complex structures is crucial: metamaterials, plasmonics, tissue engineering, and microfluidics, for example. Additive Manufacturing. Laser beams at wavelengths shorter than 300 nm are not usually suitable for SL because photons at that energy are absorbed by all molecules of the resin, not only by the photoinitiator molecules. In this regard, lasers are the most effective energy source in additive manufacturing since the laser beam can transfer a large amount of energy into micro-scale focal region instantaneously to solidify or cure materials in air, therefore enabling high-precision and high-throughput manufacturing for a wide range of materials. Efficient frequency tripling of the Nd/YAG, Nd/YVO4, or Nd/YLF lasers requires pulsed operation. The topology optimization is performed by the bi-directional evolutionary structural optimization (BESO) method. Now, they are disrupting total supply chains. But before we put on our rose-tinted glasses, we should remind ourselves that there are perils attached to these benefits that can keep top management – and even the CEO – up at night.
