The threedf or 3df, as it is a 3dprinted edf.
from foamboard to 3D print EDF Jet!

The second prototype is finished and it flew well, until my buddy crashed it on the fifth flight. It was an epic lawndart and nothing is left except electronics. This gave me the opportunity to improve it one more time. The crash cost around 4 days of printing and 12€ in filament.

Beautiful design! Looks rad in red!

looks nice. how do you like my name idea?

Its a good Idea, but its not unique enough since there are multiple 3d printed EDF planes out there. Choosing the name is probably the hardest part of the whole design process.

I decided to build one of these with a 70mm EDF. I increased the dimensions a little to compensate for the the larger EDF. Hope to maiden it once the weather clears up. Great design!!!

If you don't mind me asking, I'm thinking of a 64mm. Do you think a 1% increase would do it?

You can fit a 64mm EDF without increasing the size at all. But whenever you use larger EDF, make sure to inrease the air intake too.

you should do a ms foam design of the printed one

Very nice. Job well done. I made mine with the 70mm EDF. I crashed mine on the maiden by accidentally hitting the throttle "kill" switch.
The video below is from the 3rd flight after rebuilding the tail boom section.

Finally got to maiden mine today. I was quite nervous as it's my first EDF and I'm still quite a new pilot but I needn't have worried. Flew three batteries without any problems - I was on low rates and didn't try anything ambitious in the high wind but it's surprisingly easy to fly. Very pleased -
I guess I need to make the canopy and paint it now!

hey Doc, can you define what 3D printing foam is and how it's done?
I had a client call me yesterday looking for a PDU for a 3D foam printer they just bought and in our discussion asked if they've printed any planes. they commented they have never heard of a 3D printer that prints 'foam'...but said they use a CnC to modify foam for different things all the time.
so I'm a bit confused if 3D printing foam is not actually printing foam in a 3D printer, LoL!

Still no paint on mine yet but I've added a cheater hole underneath the fuse which seems to have added some speed. This is a great first EDF - very easy to fly. Can't help looking at it and wondering what would happen if I cut off the tail booms and converted it to a delta with elevons? I'd need to add a vertical stabiliser and maybe increase the size of the ailerons a bit, but...

I dont really know what you mean. This plane can be build using foamboard, with standard FT techniques and without the use of a 3d printer. However, I am also working on a version, which is 3d printed. The two airframes are identical in dimensions, but otherwise completely different. Its designed to be printed with standard PLA, but there is also another material called LW PLA. This material foams up during printing to be a little lighter. maybe that is what you mean.

Your center of pressure and cg would change drastically, I'd be very concerned about being in CG limits.

Agree - I’d need to recalculate the CG position. Might try an online CG calculator...

The issue is not being able to get it within CG limits though. Thats a long nose with a lot of arm.
