- 3D Printed Bug DLG - not your typical 2.5D balsa ribs. All ribs are printed with 3D engineered structures for strength and precision fit. Along with wing jigs for alignment, the precision cutout of carbon fiber spar and leading/trailing edges also add to ease the efforts required for assembly.

Looking forward to seeing the final design and flight
well thought out and wonderfully presented. this looks terrific! thank you. I have a kit for the Bug waiting to build this spring and would love to do this and compare. heh heh. just have to fix my printer sigh.
Awesome, thank you!
A very interesting design. I like your simple but ingenious wing jig. An inspirational approach I have not seen.
Is wingspan 800mm, or 1m? Saw weight was an impressive 132g in RC-Groups. Fantastic result for a 3D printed aircraft of this size. Hopefully maiden goes a well as it looks.
Thanks for watching. This is a 1m Bug.
Nice! How did you managed to cover the wing without melting the 3d printed Ribs? Are the files available to download?
Most of the film is glue to the carbon fiber rods at LE/TE, so high temp is not an issue.
For PLA area, some practice might be needed. Use low temp to activate the glue according to the film spec. For shrink at high temp, move fast and focus on small area to avoid gross heat build up on PLA.
Really nice ! Do you have printed the rips in PETG ?
No, only on PLA. These ribs are solid 100% infill. Should be straightened to convert to other materials.
Looks awesome! What type of design software did you use?
Rhino for CAD & render
Just subbed to your channel
where can I buy the stl?
do you have video of the flight?
Thanks for watching .... Will have to go through another iteration to take care some of the loose ends... stay tuned
Very nice! What glue did you use for assembly?
Thank you. I use thick CA throughout.
On a hot summers day, even a conventional wing gets very hot. Given the design and lack of specially weighted materials needed, perhaps higher temperature filament like PETG or ABS would provide better durability in the long term. Nice build & video overview! Well done, looking forward to the flight and long term updates on the wing durability.
High temp filaments are required for hot summer days or leave the glider in the car in most locations. My other gliders printed in PLA have survived more than one year in sunny California …. even in the averaged summer days (with wing sleeve cover to avoid extended sun exposure and not in the hot car ) 😀
I have been having great success with abs ribs on the enclosed Bambu labs printers. Great hi temp and so much strength I can design with less material.
@@redbaronrcyou should try ASA even higher temp resistance. I have been using playmakers ASA and prints are incredible. Little higher nozzle temp and a little lower bed temp when printing over ABS
Filament like PETG or ABS would provide worser rigidity/weight ratio, check Young's modulus and density.
3d printing is not...good technology for flying things at all. So, if u want 3d printed plane, u have to use most suitable material u can, which is PLA.
@@madcrokodile Not been my real world experience at all. Guess I'll have to check Young's modulus and density, but my design it and fly it test tells me that the worst performer I have used was PLA. I think it is exactly the rigidity that is the problem. Lightweight PLA although weaker, will even survive better in a model. Perhaps it has to do with the velocity of impact on lets say "unfriendly landings", but PLA will fracture like glass in that scenario whereas the other filaments have proven to be more resilient. I crash landed my Fokker and cartwheeled it across the ground with surprisingly small amounts of damage. My first 3D printed Pitts was all standard PLA and was destroyed beyond repair from a fairly minor hiccup. I'll never use PLA again on a flying model.
where can I get the files to try and print one?
Thanks for watching. Please stay tuned for future update.
👍👍👍
Thanks!
Interesting experiment certainly....
But Frankly it's Both Heavier and more Fragile than the simple Balsa build version.
My Lightning Bug, at 1 m (built last month) is ~ 100 gms.. Ready to launch.
With No particular efforts for lightness.
Great job & Congratulations on your outstanding build of 100g bug 👍
Material wise, PLA is no comparison to good old balsa. But 3D print is still in its infancy, with speedy progress in design optimizations and CF enforced filaments, things might start to turn in the near future😀
Hmm, balsa last for years. This one?
Lol. Oh, It’s bio degradable PLA. Won’t last forever😀
Very nice construction
Can you send me the drawing of the balsa tail
Please use lightning’ bug plan for planform and tail feather. Please refer to compact manual FAQ for links to the plan. Thx.
@@geode_rc Thanks for the quick reply
I really liked your project
P r o m o s m 😜
