  text: 'This paper proposes an innovative approach of manufacturing optical fibers
    using nozzle-mask-aided additive manufacturing. Nozzle-masks ease 3D-printing
    of optical fibers allowing the manufacturing or drawing of optical fibers of up
    to 10 μm diameter. These nozzle-masks feature a suction mechanism to prevent clogging
    of printhead and mask. The extrusion of Polymethyl-methacrylate material through
    the print-head and nozzle-mask simplifies the rapid prototyping of the optical
    fibers. '

  text: The ability to manufacture complex 3D-objects directly from its CAD model
    is the important reason why additive manufacturing is being widely used to fabricate
    cost-efficient prototypes and preferred over conventional manufacturing methods.
    Moreover, it portrays as a bridging technology to connect different scientific
    and industrial fields, e.g. Engineering, Medicine, etc. Consequently, additive
    manufacturing finds its applications in the production of patient-specific orthoses.
    This paper discusses the development of a pressure sensor based on an optical
    waveguide principle manufactured using stereolithography apparatus process to
    embed into a below-knee orthosis. For Orthopedic patients, the below-knee orthosis
    must be adjusted to the lower leg at regular intervals due to anthropometric changes
    in patient’s body to achieve proper mobility and correct load. Currently, this
    alteration relies on the patient’s estimation of support load which is only sub-optimal.
    Hence, the concept of developing an intelligent orthosis with a novel embedded
    optical system to monitor the exact support load at the neuralgic is proposed.
