Seven weeks ago, when I finished my first 3D printed project (the Transformers/GoBots unintentional crossover), Eric told me "Good job! Have you tried to printed it already assembled?", or something like that.

My answer was "WHAT? YOU CAN PRINT STUFF ALREADY ASSEMBLED? Wooooooooooow...".

You know, I'm still a rookie in this CAD and 3D printing thing and I'm learning by myself most of the time. I'm still astonished by the unlimited possibilities in this matter. So, I decided to try making a concept jet fighter. The idea was to explore how to make a few mobile parts (in this case, the cockpit and the landing gear) already assambled to the 3D printed object. In case of failure of the mobile parts, the result had to be awesome enough for justifying the printing.

I have to be honest: the final result didn't fulfill my expectatives. I think the jet is good but not awesome. But It was a very educational experience. I learned a lot of valuable lessons:
  1. Mirror pattern: Draw a line. Make half of the jet in one side of the line. Go to "Pattern", then click on "Mirror". Select the half you made and then select the line. Now, you have an entire jet. It's easy. If I had known this when I made the Transformer, I had ended it in half of the time, with more details and less "goboteness". (NOTE: In some pictures of this instructable you will see I'm working in one half, then I switch to the entire jet, then I switch back again to the half view, just for checking how it's working)
  2. Axles size: Be careful when you design the mobile parts. The axles have to be thick enough for resist the movement without breaking, regardless of the scale of your project when you print it. I made this jet thinking in accommodate one action figure, but I had to print it in a smaller scale. The back landing gear didn't resist so well after the fifth handling.
  3. Invisible jet: I found an interesting trick when I was installing the landing gear into the jet: If you want to see through the airplane for verifying the right position of the axle and you don't want to use "Materials & Outlines" in your Navigation Bar, go to "Material" in the Main Toolbar and turn the jet into glass (something like Wonder Woman's Invisible Jet).
  4. Printing: When you print something with deployable parts (like the cockpit and the landing gear), the best is printing those parts wide open, for a better cleaning of the support material and for avoiding fusion between the mobile part and the jet. I had to print this jet with the cockpit open and somebody in the lab said "What did you print? Some kind of flying alligator?". (Supposedly it was a joke, but I like the name. So, my first 3D printed jet, I name you... "FLYING ALLIGATOR"!)
  5. Cleaning: I made this project on an Object 3D printer. So, I had to remove the support material using a waterjet. Be absolutelly careful, because a water stream in the wrong part can destroy parts of your project, or worst, all of it. I worked half an hour designed the helm inside the cockpit and it was blown away in seconds on the waterjet. Next time, I will design the helm aside and leave the hole in the board, clean separately and then assemble at the end.



I have to admit something: at least, it's a cool pen top!


NOTES: I used the 123D Design 64bits for PC, version 1.1.41. My laptop is a Samsung with Intel Core i3-2370M 2.40GHz  processor, 4,00 GB RAM and Windows 7 Home Basic. The 3D printer is an Objet.

In the design, I used the orthographic view in almost all of this instructable.

I wish I could make this, but unfortunately I dont have a 3D printer :(
The plane is very well designed, you have a vote ;)

Thanks a lot! Something you can do is experimenting with 123D Design (it's free) and make some projects. Maybe one day, you will have a 3D printer near and can print them.
I am currently referring to tutorials on how to use 123D and trying to make good designs which I can print someday.

Fantastic!!! :-)

I have tried using the same program to make something, but unfortunately this program doesn't like me. :( Now that I have seen someone do it [you] it works! Thanks a lot :]

Thanks ElectraBlu! An advice: don't start trying to make something. Start playing. If you are new in this, don't take so serious your first projects or you will get very disappointed. Start basic, start funny. And then you will see that, step by step, magic happens!
A true quote
quite awesome.
hahahahaha I have that shirt [your username] :]
Thanks Resistance!!!
quite awesome but it can be hard to make sure wings/fins etc are thick enough to print properly when you often design these sort of concept objects more for rendering and animation than for printing.
Thanks!!! The wings are not the complicated part. The landing gear was a nightmare!
