CUSTOMER SPOTLIGHT... This month, we're featuring a model printing press built by our own Travis Kleckner.  He created it for a high school production of Disney's Newsies at Assumption School in O'Fallon, MO.  The printing press was self contained, moved via a battery operated gear motor, and was lit with LED strip lighting. It was built with various sheet metals, brass, aluminum, nylon, and Acetal from Speedy Metals. The frame is made from simple 2x6 dimensional lumber, and the gears are pieced together from 1/2 plywood. To make the gears all run fairly true, hubs for the wood gears were turned on a small lathe from Acetal. The hubs for the chain gears were turned from aluminum, and then drilled and tapped.  Want to see your work featured here? Send us an email at newsletter@speedymetals.com. You can also check out other great customer projects on our blog or on our Facebook page. |

DID YOU KNOW...? Did you know that metal can be made into glass? And that NASA is going to be using this kind of glass for robotics in space? 
Possible future NASA missions, such as sending a robotic probe to Jupiter's frozen moon Europa, will need gears that don't become brittle in extremely cold temperatures. Unfortunately, many metals don't meet this requirement. Enter bulk metallic glass. Solid metals normally have an organized, crystalline atomic structure. But when melted, the atoms become randomized. If you then cool the melted metal fast enough, the randomly arranged atoms are "trapped" in place, producing a glass. When this glass is more than 1mm thick, it's called "bulk metallic glass" (BMG).  Visual representation of the difference between an organized, crystalline structure and an amorphous glass structure.

That allows parts to be cast using injection-molding technology, similar to what's used in the plastics industry, but with much higher strength and wear-resistance. BMGs also don't get brittle in extreme cold, a factor which can lead to a gear's teeth fracturing." (Source) Bulk metallic glass was developed back in the 1960s at Caltech, but it was only recently that scientists at NASA's Jet Propulsion Laboratory figured out how to design and implement it into structural hardware, and put it through the rigorous testing required for components of NASA spacecraft.
