Baskılı Uçak 21 3D Baskı Modeli

Açıklama

This is a 3D printed Airliner I designed to be light wight and fly on two 70mm EDFs.

This Plane NOW FITS ENDER 3
Build Volume required is 220x220x250. The fuselage parts are 230mm tall.

RTF weight: 3,360 grams
Wingspan: 1.6m
Length: 2m
Print time: 220hrs
2kg of PLA

This plane does not have flaps or retracts to save on weight and keep the build process simple and easy. Also to keep cost down a bit.

Use 1mm Carbon fiber rods cut to 18mm for alignment of the fuselage parts do not glue them it makes it harder to get the parts together.

The battery door uses 8x 5mmx3mmx10mm magnets.
8mm Carbon tubes (Wing) 2x 19in and 2x 18in the 19in goes in the front.
Nose gear uses a small section of 6mm carbon tube and the Main gear both use a small section of 8mm carbon fiber tube.

Use 2x8 mm screw to attach servo covers and engine cover.

I modified two parts to make this build fit on an ender 3 build plate. Wing Section 1 is cut into two parts use 3 sections of 1mm carbon rods to align Wing1A to Wing1B. I also needed to cut the Mount bracket for the EDF. It is now in 4 sections to fit the smaller build plate. Glue together as shown in picture for the Ender 3 assembly Guide. If you have a larger build volume such as 245x245x260 you can print the original Wing1 and Motor mount to allow less assembly.

3D PRINTING SETTINGS
Fuselage 1-8 Print will 20mm rim on the build plate. Set the Extruder closer then standard to the bed. The first layer will print on the bed without the 20mm rim the second layer will start a 20mm rim you want the second layer to adhere to the bed.

All of the wing section, elevator sections, gear, etc are of the left side of the plane. Set the part on the build plate with the correct orientation then mirror the part to get the right side of the plane. When you place the part on the build plate and rotate to a 45 degree angle when you mirror the part rotate the part back to the same 45 degree angle to get the same infill pattern for both parts.

Tail Pipe I designed the Cowl to have interchangeable tail section to change the performance of the EDF I flew my plane with the 90% FSA tail pipe the 80% will have more speed and less thrust. You can leave this section off also to get more thrust and less speed. The 80% have a more scale look.
