Shapeways Curtiss O-52 Owl

3D-printed Curtiss O-52 is available at Shapeways:

Developed in 1939, the Curtiss O-52 was the last "heavy" observation aircraft developed for the US Army Air Corps. The concept of the two-seat observation aircraft, classed as the "O" series aircraft, dated to World War I, and in 1940, the Army Air Corps ordered 203 Curtiss O-52s for observation duties.

Upon delivery, the aircraft was used in military maneuvers with the USAAC, but following America's entry into World War II, the USAAF determined that the aircraft did not possess sufficient performance for "modern" combat operations in oversea areas. As a result, the O-52 was relegated to courier duties within the U.S. and short-range submarine patrol over the Gulf of Mexico and Atlantic and Pacific Oceans.

The O-52 was the last "O" type aircraft procured in quantity for the Air Corps. Following the attack on Pearl Harbor, the "O" designation was discontinued and the "L" series for liaison-type aircraft was adopted instead.

In November 1942, the USSR ordered 30 O-52 Owls through the Lend-Lease program. Twenty-six were shipped, with only 19 were delivered as a number were lost on the North Arctic Route. Of these only 10 were accepted into service. They were used operationally for artillery fire spotting and general photographic and observation platforms in north and central areas on the Russian Front during spring–summer 1943. One O-52 was shot down by Luftwaffe fighters. The aircraft was generally disliked in Soviet use although some were still flying into the 1950s.

Price is $8.92 per two.

interesting but the definition at 1/200 is not that fine, the elevator, struts and vertical stabilizers appear too thick, wings too, for that matter.
Good for war gaming perhaps, but as a collector of 1/200 in metal, white metal, and resin they are a bit too crude for my tastes.
I have seen that some 3D printers can also incorporate moving parts and having a turning prop and retractable landing gear could more than compensate for the other faults.
Might be better at 1/144 or 1/72?
Still it is interesting technology

Unfortunately minimal wall thickness is 1mm for this material so I can't make surfaces thinner.

In case of expensive material possible to make model more accurate. And not sure about movable parts in this scale.

Return to 1:200 scale aircraft. Both Military IDs and past or current makes.
