Liquid Silicone Rubber is a broadly used non-reactive compound. Its high resistance to extreme environments and temperatures make it a perfect seal material for aerospace, defense, and automotive components, but it is also used in sporting goods, medical devices, and consumer products. Unlike traditional thermoplastics which are melted before injection molding, LSR starts as a liquid which then cures into a solid after injected into a heated mold. It has a lower viscosity, which allows [...]

partial repost from http://www.usnews.com Fashion, movies and athletic footwear companies are among the latest users of 3D printing. Boston has a storied tradition of textile manufacturing, and, in more recent history, a tech scene. In its current exhibition, #techstyle, the city's Museum of Fine Arts looks to the future and at how some designers have interwoven fashion with technology. This 3D dress and cape is part of the #techstyle exhibit at Boston's Museum of [...]

Stratasys has once again transformed the impact of 3D printing on product development and delivery with the new Stratasys J750 3D printer. This new solution enables customers — for the first time — to mix-and-match full-color gradients alongside a wide range of materials to achieve one-stop realism without post-processing. This, together with the system’s superior versatility, makes the J750 the ultimate 3D printing solution for product designers, engineers and manufacturers, as well as service bureaus. [...]

When you are looking for a way to make very functional FDM parts look closer to being traditionally manufactured parts there are few methods out there. Some of these require manual working of the part, some mechanical, while others require almost no work at all. One of the major concerns that comes up regularly is the dimensional stability of the parts after the finishing process. When tumbling parts or sanding them you are typically removing [...]

You can’t solve an 80-year-old problem with 80-year-old technology. Take stereo speakers, for example.  Conventionally designed and manufactured speakers almost universally suffer from some level of “back wave” distortion; this occurs when the audio signals fired to the back of the speaker bounce off the cabinet walls and interfere with the signals sent to the front of the speaker. In the 3D printed Aleph1 speaker design, sound travels in a perpetual self-feeding loop, preventing [...]
