"3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes."

The Grahame-White Factory at Hendon is a virtual shrine to early aviation. Even setting aside the prominent rôle its founder, Claude Grahame-White, had in the establishment of aviation in the U.K., and the significance of the early factory buildings themselves (Grade II* Listed), the Royal Air Force Museum, London, has chosen to display some superb early aircraft (plus some replicas) in this wonderful setting.

"Build a T-Bott II robotic arm that illustrates hydraulic power and mechanics. See how syringes, tubes and water work together to power the parts of this robotic arm. Each control moves one of the T-Bott II's axes. The four controls can be used one at a time or all at once by a team of students."

"The team, led by Professor Simon Cox, consisted of Richard Boardman, Andy Everett, Steven Johnston, Gereon Kaiping, Neil O'Brien, Mark Scott and Oz Parchment, along with Professor Cox's son James Cox (aged 6) who provided specialist support on Lego and system testing."

"It is fairly simple to construct a working motor similar to Faraday's original motor that will amaze your students. Due to safety concerns, salt water is substituted for mercury."

"While not as large as the deHavilland Beaver, the Murphy Moose is often compared to the Beaver and for many, the Moose is a viable alternative to the expensive Beaver. It is powered by a nine cylinder Russian M-14P radial engine that is supercharged and produces 360 hp. Models are available with a Lycoming in-line six cylinder engine that produces 260 hp. The Murphy Moose seats six people. "

"Chevak students and family members gathered in brisk conditions to watch as the Rans S-6S Coyote took flight over the tundra, after receiving its airworthiness inspection and certification. The aircraft was built by Chevak High School students as part of an aviation course offered by the school located on the tundra in western Alaska. "The aircraft was beautifully built and was obviously the pride of the aeronautics class at the school," said Designated Airworthiness Representative (DAR) John Davis."

Homebuilt aircrafts are built of a very wide variety of materials, wood, steel, aluminum, composites and fabric. Although most have a combination of these materials involved in their construction, there are basic configurations. All metal, all wood, composites and tube and fabric also know as tube and rag.
