Almost 120 years ago, mankind took to the skies for the first time when the Wright brothers successfully flew their first aircraft in Kitty Hawk, North Carolina. Of course, we had been dreaming of and attempting to fly long before that. Hot air balloons first took mankind off the ground in 1783 in Versailles, France, and Leonardo Di Vinci had numerous drawings of flying machines, flight captures our imaginations. If like so many you dream of flight, this contest is for you.

LW-PLA/PLA RC Plane – Pusher Propeller by TinyTexas

Making things fly is one of the more enduring engineering challenges in the world, engineers and inventors are constantly trying to make better flying machines. We think this is a perfect challenge for all of you. There are many ways that items can fly, float, hover, or glide and we would like to see them all. This contest is open to Planes, helicopters, quadcopters, gliders, or any other kind of flying machine.

We should define what it means to fly, float, or glide to help reduce the entries from those that think they are clever with a comment like “if thrown, anything can fly”. Any valid entry once let go of in a way intending to launch the object must have some form of lift capable of slowing or preventing its descent by gravity. If your object has no more lift than a stone or a ball, it’s not a valid entry to the contest.

Judging Criteria

  • Overall quality of the model.
  • Printability – Whether the model has an optimal orientation, whether it is divided into multiple parts so it can be printed more easily (without supports) etc.
  • Originality – If you create something truly unique, it will be rated better than a slightly altered existing model.
  • Popularity – Share your model to increase its popularity, and prove that users appreciate such a model.
  • Your other works – In case we can’t decide between two favorite designs, we often check your other models to see what you can do.
  • Assembly instructions – If your model consists of multiple parts, we check how easy it is to assemble the final product.
  • Photo quality – Well-lit, in focus, and clear photos help show off your work and help us pick the best designs.

How to participate?

It’s easy to participate in this competition. Just follow these simple instructions.

  • Design and create a model or improve an already existing one (“remix”) so that the result fits the theme of this contest. The model has to be printable on an FFF/FDM or SLA 3D printer (any manufacturer and model). This also means that you don’t need to own a 3D printer to participate. When creating the model, keep in mind the pros and cons of various types of 3D printing technologies and what can and can’t be actually done.
  • Upload the model to and make sure it contains:
    1. Model in .3MF or .STL file format (print files are optional)
    2. Photo or render of the model (ideally both)
    3. Model description
  • Add the model to the contest. You will find the new competition button just bellow the download button on the print’s page after you publish your print. Click the Compete medal and select the “Make It Fly” contest. After that, your print will be shown on the contest page and you will be in the running.

Of course, you can share your model on social networks (Facebook, Instagram, Twitter, Pinterest,…), and don’t forget to add @printablescom. This can help increase the popularity of the model.
