On-X Air

We were approached by Reflow to experiment with their new 3d printing filament made from recycled plastics. Conceptually we wanted to focus on leightweight and efficient designs to keep in line with the sustainable values of Reflow. As a theme we quickly settled on aerial objects, thus the name On-X Air..
It is part of our series where we do experiments to discover the possibilities of 3d printing and rapid manufacturing (Print on X, Panel Light).

Paper Plane

Here we merged the folding principles of paper planes and the printing-on-foil technique. This way we were able to use super light foils to fill the surfaces and add a printed structure to increase durability and performance. In addition to the aesthetic value of the printed structure, the product also becomes its own manual. Furthermore, you can use the print to distribute the plane’s weight and make the plane perfectly balanced. In the end, we have the well-known shape of a paper plane but with these extra functional and aesthetic “layers”.


This windmill is a combination of a 3d printed, solid core and three blades made out of a lightweight print on refractive PTEG foil. The result is durable enough to resist the force of wind, light enough to rotate and is quick and easy to produce. The iridescent coating gives a beautiful rainbow effect when in motion.

This second version of a windmill is made out of two fully printed bodies. When they are exposed to the wind they will rotate in opposite directions. This contra wise movement and the emerging visual effect boost the playful character of this object.


We were starting with observing the playful and smart designed world of lightweight structures (such as toy planes, windmills) and role models provided by nature (flying seeds). After trying a few base materials to print on it was soon settled to keep the the filament and base material the same (PETG) to keep the objects to a certain degree recycable.

Do you want to try it yourself? Feel free to download THIS .stl file for printing.

Some recommendations for your slicer engine: we recommend one layer height (max. 0.2mm) // top and bottom thickness needs to be zero // your infill pattern will affect your planes stability (standard grid pattern should work fine). Use file at your own risk. We take no responsibilty in terms of functionality or any damages/issues arising from using the file.
