In recent years, 3D printing technology has experienced explosive growth, which has had a certain impact on all walks of life. At the moment, it seems that there is a revolution in the fiber manufacturing industry. It is understood that last month, scientists at the University of Southampton used 3D printing technology to develop news on optical fibers with various complex structures and shapes. Recently, the University of Sydney broke the news that a team of scientists at the school found a new way to make fiber using 3D printing technology, which not only saves cost and labor, but also increases the possible shape and usable of the fiber. material. The results of the University of Sydney research have been published in the journal OSA Optics Letters, entitled "Air-structured optical fibre drawn from a 3D-printed preform." The research team at the school actually created a new preform with ordinary FDM desktop 3D printing technology (the fibers were all made with preforms). The research team is led by Professor John Canning of the Interdisciplinary Photonics Laboratory (iPL) at the University of Sydney. The team first used the Inventor software to design the shape of the preform and then printed it out with a Redback-2 desktop 3D printer from the Australian local manufacturer Deltastine. Of course, because it is used for optical research, scientists have carefully selected a transparent wire called SBP as a printing material on the market. The so-called SBP is actually a modified ABS made of styrene-butadiene copolymer and polystyrene. The researchers pointed out in the paper that SBP was chosen because of its transparency, flexibility, and discoloration. These 3D printed preforms are then weighed into thin fibers using a computerized draw tower. Although the research team encountered some twists and turns because of the fiber that was never made using SBP materials before, the end result is amazing. The researchers arbitrarily chose a preform design that consisted of six tubular holes surrounded by a solid core. They originally printed 1.6 cm in diameter and 10 cm in length. However, after drawing, the fiber has a diameter of 712 microns and the other is 605 microns (the fiber has an elliptical cross section due to some problems with the print setup and materials). More importantly, even at such tiny scales, they remain the same shape so that light can pass through them in the form of telecommunications transmission bands. In other words, scientists have demonstrated the possibility of using 3D printing to make fiber optic cables with unique shapes for telecom applications.
Dog Bag
Dog Bag can be used for many purposes - the Dog Carrier Bag can be used as a fashion statement, an extension of your dog's style. Regardless of how you use a dog bags, they are a conventional and safe way of transporting your dog. Carriers for dogs are the best way of traveling far distances with your furbaby. They are not only comfortable, but also keep your pooch warm and secure.
Compared to the plastic dog carrier, the dog bag is softer and can be easily and quickly disassembled, and the dog bag has a strap that can be carried like a backpack. It is more labor-saving, stylish and can be used while walking or cycling. Very safe and convenient. In addition, our dog bag material is also a thermal insulation material, which can give your pet better insulation in winter and has all-round protection for your pet.
