В ювелирном деле популярны металлические украшения, напечатанные на 3D-принтере, а другие материалы — нет. Возможно, не боясь тигра, ювелирный бренд Eternha, основанный в 2020 году, экспериментирует с изготовлением мужских браслетов из композитных материалов. Они выбрали композитный материал из нейлона и стекловолокна, промышленный материал, обычно используемый в автомобильной и аэрокосмической областях, а также материал, широко используемый в настоящее время в области 3D-печати. Он обладает хорошей ударопрочностью и ударной вязкостью, имеет глубокий блеск после ручной полировки и одобрен для контакта с кожей. Instead of 3D-printing the entire string of bracelets, Eternha 3D-printed the beads of the bracelet and combined them with obsidian, 925 silver, and stainless steel beads to create a multi-material mix of bracelets. Eternha says they want to incorporate a variety of elements into their bracelets, with 3D-printed nylon glass fiber beads that can be designed in a variety of shapes (cylinders, hexahedrons, irregular shapes, etc.) and the ability to incorporate logos such as logos to create unusual fashion pieces. LFT-G PA6-NA-LGF LFT & LFRT, Long fiber reinforced thermoplastic engineering plastics, compared to conventional short fiber reinforced thermoplastics, typically have a fiber length of less than 1 to 2 mm in conventional short fiber reinforced thermoplastics, while the LFT process The thermoplastic engineering plastics produced have been able to maintain fiber lengths above 5 to 25 mm. The long fiber is impregnated with a special resin system to obtain a long strip which is sufficiently wetted by the resin, and then cut into a desired length as required. The most used matrix resin is PP, followed by PA6, PA66, PPA, PA12, MXD6, PBT, PET, TPU, PPS, LCP, PEEK and the like. Conventional fibers include glass fiber and carbon fiber. Special fibers include basalt fiber and quartz fiber. The LFT of the long fiber material can achieve better mechanical properties. According to the final different applications, the finished product can be used for injection molding, extrusion and molding, etc., directly used to replace steel and thermoset products.
