Flying Ring: 65 meters flight (71 yards)

This flying ring can be used in a manner similar to a frisbee (flying disc) or aerobie (flying ring). To play with this flying ring, simply hold it with a flat grip and give it a smooth, level throw using a flick of the wrist - just like you would with a frisbee. It performs exceptionally well in open spaces like parks or beaches, offering long, stable, and accurate flights thanks to its airfoil design. Whether you're playing catch or trying to achieve maximum distance, it's both fun and easy to use, making it a great choice for casual outdoor play or friendly competitions.

It easily flies up to around 65 meters (71 yards).

What makes this flying ring different, and unlike many other 3D-printed flying rings, is its unique structural design. The flying ring has an airfoil section. An airfoil (aerofoil) is a streamlined body capable of generating significantly more lift than drag. Wings, sails, and propeller blades are examples of airfoils. The airfoil section of the ring is optimized for stability and long-range flight.

The outer TPU part of the ring makes it more resistant to damage if it accidentally hits a hard surface such as asphalt or concrete, while also increasing safety and making the ring easier to catch. The inner PLA part adds structural integrity and an additional color, so the ring still looks cool even when printed in black TPU.

This ring is more complex than many other 3D-printed flying rings. The bottom of the ring is not flat, so it has to be printed on top of a support interface, but mixing PLA and TPU helps simplify support removal and creates an almost perfect bottom surface. 

That's a great model to test your H2D printer's multi-filament printing capabilities!

The ring weighs only 40 grams and has an outer diameter of around 24 cm.

Instructions

1. Print the ring

    

   This flying ring has to be printed with two different types of filament: TPU and PLA.

    

   a) H2D printers support multi-material printing with PLA and TPU 90A.
   
   b) Optional: I was able to print this ring on A1 printer without AMS using customized g-code (11 manual filament changes). Can't be printed from Bambu Handy, Bambu Studio is required.

    

   Take a look at at Multi-color without AMS (!) & with AMS - Test for the instructions and g-code for A1.
   

    

   I used a 0.6 mm nozzle to speed up printing and reduce the risk of nozzle clogging with TPU.

    

2. Remove it from the build plate together with the PLA support.

    

3. Remove the PLA support from underneath the ring. It should be relatively easy to remove; TPU doesn't stick well to PLA.

Note: I tested the ring. The PLA insert works really well. The thin PLA insert is flexible enough, and the TPU protects it effectively, even when the ring hits hard surfaces like asphalt or concrete. So I see no significant reason to use PETG. However, I believe it's possible to use PETG instead of PLA for the insert if you want, but you'll still need to use PLA for the support interface. It would be difficult to remove a PETG support interface, because TPU and PETG bond well.

WARNING! The ring is very lightweight and flexible, but be careful nonetheless, and choose a location where you can't accidentally hit and injure someone or damage anything. If you're going to throw the ring with a lot of force, make sure you're in a clear area with at least a 100-meter (110-yard) radius. Play with caution and at your own risk. The TPU part makes the ring stronger, but hitting hard surfaces like asphalt or concrete may still damage it.
