Product News Nylon FDM Material Offers Greater Strength Stratasys has introduced a nylon material designed to offer greater resistance to breakage and better impact strength than other fused deposition modeling (FDM) materials. Specifcally engineered for the company's line of Fortus 3D production systems, FDM Nylon 12's elongation-at-break specifcation is said to surpass that of other 3D-printed nylon 12 materials by as much as 100 percent. This can enable manufacturers in aerospace, automotive, home appliance and consumer electronics industries to create durable parts that can stand up to high vibration, repetitive stress or fatigue. FDM Nylon 12 is available for the Fortus 360, 400 and 900 systems. It is initially being offered in black and is paired with SR110, a new soluble support material that the company says is optimized for the nylon material. stratasys.com Ultrasonic AM Machine Welds Metals into 3D Parts Large-Format Printer Uses Photocure Technology EnvisionTEC's Xede 3SP large-format 3D printer uses the company's scan, spin and selectively photocure (3SP) technology to quickly produce accurate parts from STL fles, regardless of geometric complexity. According to the company, the surface quality of the printed parts shows no signs of stairstepping on the inner and outer surfaces. The machine had been part of the company's Perfactory family of 3D printers that use digital light processing (DLP) technology. The new 3SP approach, which allows for larger build sizes, employs a multi-cavity laser diode with an orthogonal mirror spinning at 20,000 rpm. It can be used to produce everything from concept models to functional parts with minimal material waste. envisiontec.com 14— AM Supplement The SonicLayer 4000 from Fabrisonic LLC features the company's patented ultrasonic additive manufacturing (UAM) technology, which uses sound to weld together metals into solid three-dimensional shapes. Because this process uses solid state welding, it lends itself to welding dissimilar metals, including aluminum, copper, stainless steel and titanium. And, unlike a metal fusion process, UAM avoids brittle inter-metallics that form during the combination of two or more metals, the company says. Periodic machining operations help create further details on UAM-built objects, including deep slots; hollow, latticed or honeycombed internal structures; and other complex geometries. The SonicLayer 4000 features a 9-kW welding head for additively manufacturing the solid metal parts and a three-axis CNC mill with a 25-hp, 8,000-rpm spindle for machining them. The 4000R model also offers a fourth axis that rotates underneath the traditional three-axis motion system. This additional axis positions a cylindrical part under the welding system and enables 3D printing of metal features on the OD of a shaft, cylinder or pipe. fabrisonic.com
