Possible Print Failures


You may encounter print failures due to lack of internal supports when spanning wider gaps as shown in the larger box section (middle section first image), when the upper surface is created.

Planning to design a dedicated FPV plane later this year. Targeting October most probably.

Finished


Printed, glued, covered, assembled - ready to go! Ok, ok, it already took 2 month to finish
I first printed test parts in PLA and tried to cover them with HK covering film and then Oracover, both with no luck. Nowhere near to!
Then I decided to print it in ABS, because of the better heat resistance while ironing and also in sun. Meantime I ordered some Solarfilm, which finaly worked perfect for me.

Great design, thank you KRAGA!

Not flown yet...

Hi Aerosol2,

I am very interested in what you have done. You found that ABS worked much better than PLA because it can handle higher temperature. How did you go about in ironing on the Solarfilm? Did you have to prepare the surface of the plane ABS parts in anyway to get it to stretch the Solarfilm evenly over the wings.? Was there any temptation for the ABS to melt during the heating process?

I have just started printing 4 segments of the wing with PLA and the covering test I have done all failed .

I looked at other options but with this being a glider I did not want to add any more weight than necessary. After I taped all of the open ends I sprayed the airframe with a dusting of 3M77 then ironed on the film. I used the recommended SolarFilm with great success. The weather has been pretty crazy and have not got a window to fly the Kodo yet.
Hi Electric -2000,

I see you were successful using PLA. Can you please elaborate what your settings were and at what temperature you ironed the cover on to the plane wing.
Did the 3M77 have a big role to play and did you have to smooth the wing sections at all before applying the film to cover it.

Hi Johan510,

No, I didn't prepare the ABS before ironing in any way. Just covered the wings like wooden wings (I guess, because this was my first covering job).
And no, there was no tendency for the ABS to melt. I was not VERY careful. Quite easy with Solarfilm Lite, using 100C to stick and 125-130C to shrink.

I also tried to cover ABS with Oracover 3M77 sprayed before. Didn't work, ABS melted - fail!
Changing over from HK film or Oracover to Solarfilm Lite did the trick. Solarfilm Lite is so much softer, thinner, smoother, whatever.

Maybe PLA also worked for me, if I started with Solarfilm Lite.

I used a very light mist of 3M77 over the PLA, this was to hold the covering in place while I ironed the edges. I learned way back about covering large surfaces, you only iron the edges and shrink the remaining tight. That said, I basically created an envelope around the wing by sealing the leading and trailing edges to the underside film, then shrank it tight. Then I went back and hit the leading & trailing edges with a bit more heat from the iron to get it to adhere to the PLA, doing it this way allowed me to control the heat much better.

Electric 2000,

Thank you for this valuable information. Very much appreciated. What was the temperature setting on your Iron?

Aerosul2,

Your input is very much appreciated. Looks like the answer to the problem is Solarfilm Lite. Will retry with PLA first before moving on to ABS.

Maiden successful


Maidend mine today. Wow, this bird is amazing!! And it survived
Fantastic airplane performance, this was far more than expected.

Perfect day

I might have to try this one later this spring-summer.
