CBS News SANTA MONICA, Calif. - What prompted Friday s rampage in Santa Monica is still unclear, but on Saturday there was ample evidence of what the gunman had on him. He was armed wit stanley tumbler h a .223 semi-automatic rifle, similar in type to an AR-15, said Santa Monica Police Chief Jacqueline Seabrook. He was in possession of multiple loaded magazines, a handgun and the upper receiver for an automatic ri stanley deutschland fle. Seabrook remained tight-lipped about the investigation, not releasing the names of the shooter or most of the victims.The attacks began just before noon at a house on Yorkshire Avenue.

It may look like an alien desk tidy, but you ;re actually looking at a bicycle frame hot off the 3D printer. The frame鈥攕hown below in its fully assembled form鈥攊s the brainchild of Renishaw, which makes metal 3D printers, and Empire Cycles. Based on Empire MX-6 mountain bike, it printed in titanium alloy which winds up with an Ultimate Tensile Strength of more than 900 MPa. The design was honed using topological optimization. That may sound complex, but in reality it means using a software package to smartly distribute material: Material is removed from areas of low stress until a design optimized for load bearing is evolved, explains stanley cup Renishaw. In other words, it takes away redundant material to create the lightest possible frame for a given set of design constraints. The bike isn ;t on sale yet, but it is unde stanley quencher rgoing further testing by Swansea University鈥攊 stanley thermos n the workshop and on the mountainside鈥攗sing strain gauges to measure the frame performance. Eventually, though, you might just be able to download the thing and hit the trails鈥攏o bike shops required. [PhysOrg] 3D printingBIKESTitanium |
