There’s so much role of 3d printers in everywhere just take an example of Ukraine Russia war, where 3d printed drones being used and it’s surprising that how apparently civilian made drones could be used at the time of need. Of course illegally they should not be used. Since the world has braced 3d printers in every thing let’s look closely he could 3d print drones.
(I) Design – Create or obtain a 3D model of the drone frame and components using CAD software and there are many YouTubers who would offer these models for free and there are other open-source designs are available online for beginners.
(II) Material/Filament selection – Next we must choose appropriate filaments, typically lightweight and durable materials like ABS or PLA plastic whichever suits your model that you want to build.
(III) Printer setup – Now we must ensure that the 3D printer is properly calibrated and set to the correct temperature for your chosen filament.
(IV) Printing – Now comes the main part of printing them we would print the frame and components in sections. This often includes the main body, arms, and mounts for motors and electronics.
(V) Post-processing – We must ensure and make that we have Sand and finish the printed parts as that needed for smooth operation.
(VI) Assembling – Now we would put together the 3D printed parts along with purchased components like motors, flight controller, and batteries to make it functional according to our needs.
(VII) Configuration – Now we would set up the flight controller software and calibrate the drone’s systems
(VIII) Testing – Conduct controlled test flights in a safe, open area, following all local regulations and never test it where it’s not legal or seek permission before flying that.
Here is a video that would show you how to achieve that step-by-step
