I will be posting new live streams daily. Each view gets me 10 additional entries for the drawing. Appreciate a daily view from you all!

Cool stuff.
Much of the 3-D printing stuff I've seen looks "rough" on the surface.
Do you plan to sand them to a smoother surface?

It's smoother than the photos make it look.
Most of the time, no sanding is required. There will be very little to no sanding on this project.

@mark I assume you purchase the motor? That’s not something that can be printed, right?

New part, Body segment 9. new stream. More chances to win! lol
No, seriously, click the link!
The airframe so far, dry assembled on the dining room table.
This is not a small RC plane. I still have to print the front engine cowl that extends the length another 180mm or 7" Then the tail section and rudder add some more length.
An additional 5 segments that stretch the entire length of the fuselage and the canopy still need to be printed. They form arched top of the fuselage.
All of this will be held together with carbon fiber rods and adhesive. Adhesive that I have to wear a respirator to use.

How expensive is the filament for this type of project?
IOW, without all the "other stuff" that goes into an RC airplane of this size, what's the cost of materials?

@george-k So far I have used about $12 in filament. After every thing is printed I suspect it will be between $20 and $30

And how much for the non-printable parts?
You said this looks like a pretty big plane. How flyable by an amateur?

Reprint of Body Segment 12 in PLA silver after failed print in PETG. The PETG was not 100% at fault. This part needs printed supports for the internal bracing.
The designer recommended that I print in PLA vs. PETG. Most of the plane is already printed in PETG. I have to try this PLA print to see if what he says about the quality of the finished product is true. If it is significantly better, I will be reprinting some parts.

Frustrating. The 2nd attempt to print body segment 12 in PLA, failed. Hopefully this one will work. Back to PETG but with some internal supports. |

Why does it fail? What happens?

Various things can make a print fail. In this instance, the walls on these parts are the thinnest I have ever seen in a 3D printed model. Every part has some "defects" that I need to go over with some epoxy and possibly some thin fiberglass cloth to rienforce the structural integrity.
The particular part failed the first time because I didn't use supports. The second time was due to it cracking apart when I attempted to remove it from the build plate.

Finally got Body segment 12 to print. Back to PETG filament.
Segments 13 & 14 printing now.

I would love to have heard the words you used when that happened.

It was definitely NSFW.
