CNC Machining: begin with a huge strong block and take away material to generate your part.
3D Printing/Rapid Prototyping: produce the element by binding loose material layer by layer.

Two fantastic tastes that taste great collectively.

Steven F. Udvar-Hazy Center: Grumman F6F-3 Hellcat

Quoting Smithsonian National Air and Space Museum | Grumman F6F-three Hellcat:

The Grumman F6F Hellcat was originally conceived as an sophisticated version of the U.S. Navy’s then existing front-line fighter, the F4F Wildcat (see NASM collection). The Wildcat’s intended replacement, the Vought F4U Corsair (see NASM collection), first flown in 1940, was displaying fantastic promise, but improvement was slowed by difficulties, which includes the crash of the prototype.

The National Air and Space Museum’s F6F-3 Hellcat, BuNo. 41834, was constructed at Grumman’s Bethpage, New York, factory in February 1944 under contract NOA-(S)846. It was delivered to the Navy on February 7, and arrived in San Diego, California, on the 18th. It was assigned to Fighter Squadron 15 (VF-15) on USS Hornet (CV12) bound for Hawaii. On arrival, it was assigned to VF-three exactly where it sustained damage in a wheels-up landing at NAS Barbers Point, Hawaii. Following repair, it was assigned to VF-83 where it was utilized in a coaching part until February 21, 1945. After quite a few transfers 41834 was converted to an F6F-3K target drone with the installation of sophisticated radio-control equipment. It was painted red with a pink tail that carried the number 14. Its mission was to be utilised in Operation Crossroads – the atomic bomb tests at Bikini Atoll. It flew on June 24, 1946, with a pilot, on a practice flight and was launched, unmanned, quickly after the first bomb test. Instrumentation on board and photographic plates taped to the control stick obtained data on radioactivity. Three far more manned flights preceded the final unmanned flight on July 25, 1946, which evaluated the first underwater explosion. Records indicate that exposure of this aircraft to the radioactive cloud was minimal and residual radiation is negligible.

F6F-3K 41834 was transferred to NAS Norfolk and logged its final flight on March 25, 1947, with a total of 430.two flying hours. It was assigned to the National Air Museum on November 3, 1948, and remained at Norfolk until October four, 1960, when it was moved by barge to Washington and placed in storage. In 1976 this Hellcat was loaned to the USS Yorktown Museum at Charleston, South Carolina. A superficial restoration was performed at the museum, but since of the harsh atmosphere and its poor situation the Hellcat was returned to NASM on March 16, 1982. In 1983, it was sent to Grumman Aerospace exactly where a team of volunteers completely restored the aircraft. In 1985, it was shipped back to the Paul E. Garber Preservation, Restoration and Storage Facility in Suitland, Maryland, and place in storage. NASM’s F6F-3 Hellcat is scheduled to be displayed in the new Steven F. Udvar-Hazy center at Dulles International Airport in Virginia in 2004.

This video shows some sample parts 3D printed on a ZBuilder Ultra speedy prototyping machine from Z Corporation. These 3D prints are really precise and resemble real manufactured moulded objects each in appearance and in strength and flexibility.

Denna video visar flera plastobjekt som skapats med 3D-skrivaren ZBuilder Ultra från Z Corporation. Dessa prototyper påminner starkt om riktiga plastföremål som tillverkats genom formsprutning – både till utseende man även i hållfasthet.
