“It is a 1m wingspan, mostly 3D printed flying wing,” Roy tells 3DPrint.com “I’m using a built-up construction technique that’s familliar to traditional balsa and plywood airplane model builders. However practically all the parts are 3D printed. I also use carbon fibre spars, balsa for sheeting and shrink wrap (ultrakote).”
The flying wing, as you can see in the photos, is quite the amazing design. It is entirely open source, and Roy himself is a huge supporter of open sourcing of 3D printable designs. He believes that more people should be using this type of licensing in order to help 3D printing grow as a technology.
Roy isn’t alone on this project, as he has received the help of many along the way. In fact, Brook Drumm, CEO of Printrbot, has lent a huge hand to Roy’s cause with a major contribution to the project.
“I started experimenting with different ways of using my 3D printer to make airplane models when a picture I posted of a few wing ribs mocked up to form a wing with a bit of balsa sheeting caught the attention of Brook Drumm from Printrbot,” Roy tells us. “We got to talking by email and he wound up giving me a Printrbot Go Large to help me out. It’s massive, with a 600mmx300mm (2’x1′) build plate. A large build plate is pretty useful for making model airplanes.”
The huge Printrbot Go Large allows Roy to print larger parts and fewer of them, which leads to a larger, more solid body, while remaining extremely light-weight at the same time. The latest iteration of Roy’s flying wing only weighs about 650 grams, and this includes all of the electronics on board, such as the servos and motor.
Projects like this take a lot of time and work to perfect, but Roy is getting pretty close to doing so. As expected though, Roy has run into a few minor problems along the way.
” I recently crashed my first prototype when trying to find where to place the center of gravity,” he tells us. “No big deal, I salvaged the carbon fibre spars and am printing out my 2nd prototype. I corrected my error, this one will fly.”
“This is a demonstration project to encourage others to follow in my footsteps. I want others to create new designs and release them under open source licenses so other people, such as myself, can eventually 3D print any model they desire from a large library of open source designs created by the community: P-51 models, Spitfires, Cessnas etc.,” says Roy.
