World’s First 3D Printed Plane Takes Flight


Created on an EOS EOSINT P730 nylon laser sintering machine, its wings,

hatches and control surfaces basically everything that makes up its structure and

aerodynamic controls was custom printed to snap together. It requires no

fasteners and no tools to assemble.



Current 3D Printing Technologies
Stereo lithography - Stereo lithographic 3D printers (known as SLAs or stereo

lithography apparatus) position a perforated platform just below the surface of a

vat of liquid photo curable polymer. A UV laser beam then traces the first slice

of an object on the surface of this liquid, causing a very thin layer of

photopolymer to harden. The perforated platform is then lowered very slightly

and another slice is traced out and hardened by the laser. Another slice is then

created, and then another, until a complete object has been printed and can be

removed from the vat of photopolymer, drained of excess liquid, and cured.

Fused deposition modelling - Here a hot thermoplastic is extruded from a

Temperature-controlled print head to produce fairly robust objects to a high

degree of accuracy.



Selective laser sintering (SLS) - This builds objects by using a laser to

selectively fuse together successive layers of a cocktail of powdered wax,

ceramic, metal, nylon or one of a range of other materials.

Multi-jet modelling (MJM )- This again builds up objects from successive layers

of powder, with an inkjet-like print head used to spray on a binder solution that

glues only the required granules together.

The VFlash printer, manufactured by Canon, is low-cost 3D printer. It’s known

to build layers with a light-curable film. Unlike other printers, the VFlash builds

its parts from the top down. Desktop Factory is a startup launched by the

Idealab incubator in Pasadena, California.
