Spirit of Detroit statue to get 3D scanned 1

If you happen to be in the downtown Detroit area on Thursday May8, you might be able to get a glimpse of the Spirit of Detroit statue as it gets 3D scanned. Engineering services house CAM Logic Inc. will scan the Spirit of Detroit Statue in front of the Coleman A. Young Municipal building to create a miniature-size statue using 3D printing. CAM Logic plans to use a A laser scanner will scan the statute and create a digital model. The scanner is composed of two pieces of equipment — the tracker and the scanner.

Gallery: 3D-printed part roundup 2
Recent examples of 3D printed parts include electrostatic loudspeakers, objects knit from yarn, sensors, and printed electronic components.
Gallery: Crowd sourced projects of the week - Desktop CNC, nat-gas Mustang, A/C app, and a portable wind turbine
Engineering projects that include a desktop CNC, a natural gas-powered Mustang, a smart phone A/C app, and a portable wind turbine are making the rounds on crowd-sourcing sites.
When Flexible Cable Doesn’t Flex for Long
When science-fiction writer Isaac Asimov first penned stories about positronic robots in the 1940s, it’s doubtful he could have foreseen that one of the weak points real robots would have is relatively mundane: the cabling used to connect their moving parts. This wiring can flex millions of times in normal use.
If Starbucks behaved like a manufacturer 8

Pity me. I’ve just learned I must sit through six online management-training courses every quarter. I just finished my first experience with this new requirement and it has lived up to my worst expectations.

Slide show: Scenes from the SAE World Congress 2014
Interesting technologies on display at the Society of Automotive Engineers show this year ranged from piston engines without connecting rods to dual-clutch transmissions and A/C evaporators that work even when the engine is off.
Say goodbye to half-empty boxes: Packaging machine sizes cardboard just right
Packaging machinery automatically cut corrugated cardboard into boxes sized for incoming product. The box forms around the product. Servomotors and drives let special packaging machines correctly size corrugated cardboard boxes for any product, so there's no need to fill empty box space with extra cushioning material.
Shock at the coffee shop 2

I may have ruined dinner for someone awhile back. It all began when table conversation at a dinner party turned to coffee shops and, more specifically, disposable coffee cups. The woman on my right was convinced the paper cup she used for her morning latte was completely recyclable and should go in a recycle bin.

Magnetic refrigeration heats up

The traditional vapor-compression cycle used in refrigeration may be relegated to the history books if researchers are right about magnetic (magnetocaloric) refrigeration. At least one major appliance maker plans to commercialize magnetic refrigeration for use in the home. The rationale for the change is that the technology uses no refrigerants or compressors and is said to be 20% more efficient than conventional techniques. It could also work well in HVAC.

Propeller gets immortalized in digital data 1
A digitizer captured the dimensions of one of the propeller blades on the fishing vessel named Harmony. A laser tracker helped measure a 25-year-old propeller in just a few hours as a means of generating a CAD model from which copies could be made.
Modular connector makes stage equipment simpler

The end of the semiconductor industry? 3


When Janusz Bryzek, vice president of MEMS and Sensing Solutions at Fairchild Semiconductor Inc., isn’t busy starting companies, he is engaged in saving the world. Or at least that is one interpretation of his recent endeavors toward a concept called the Trillion Sensors Movement. Bryzek, who received his MSc and PhD degrees from Warsaw Technical University, co-founded (among others) sensor makers SenSym, IC Sensors and NovaSensors in the 1980s, and Jyve Inc. in 2009 which Fairchild eventually acquired.

Could engineering school be free? 2
Could you replace an entire semester of engineering school with free Massive Open Online Courses (MOOC) equivalents?
Gallery: Weird 3D printing machines of the week

If you think the world of 3D printing has pretty much settled on ink jet printing technology for creating additive parts, guess again. This past week saw a variety of odd-ball additive techniques getting notice. Some of them are experimental, and time will tell whether some of them will lead to techniques that are useful for mainstream users.
