3D printing is a complex technology that requires creativity, mathematics, and computer-aided design (CAD) skills to master. However, with the right hardware and software, modeling skills, and an understanding of how this technology works, 3D printing can become much easier. In general, 3D printing is not difficult to learn. The basic skills you need are the ability to use a computer and follow step-by-step instructions.
The aeronautical industry currently uses 3D printing in various ways and has incorporated it into its operations. To produce high-quality decorative objects, you will need to be familiar with post-processing a 3D printed model, which includes processes such as sanding, priming, painting & smoothing, and polishing. If you have the necessary skills and are interested in both categories, you will likely enjoy 3D printing and never run out of things to print. To print amazing looking 3D prints and design basic 3D prints yourself, however, requires some learning.
After that, you should watch some YouTube videos or read the user manual to learn how to make a 3D impression. If you need specific plastic parts and components that are difficult to find, such as a particular size gasket or an SD card holder capable of holding an exact number of SD cards, you will benefit greatly from 3D printing. Once you have your 3D printer set up, you'll need to play with the 3D printing software called Cura. Because of its highly complex nature involving many different scenarios, it's virtually impossible to tell if 3D printing is easy or difficult to learn without going into detail.
I made a really good introductory video that explains pretty much everything you need to know to start 3D printing. Ultimately, since it all comes down to factors like how much you enjoy the process of learning more about 3D printing, how much 3D printing benefits you, and whether you have enough time, deciding to choose 3D printing as a hobby is entirely up to you. Modern technology has taken 3D printing to the next level by creating hundreds of new and complex ideas and products. On the other hand, with a fully assembled 3D printer, the demand for mechanical and electrical knowledge will be virtually non-existent. You will only need to perform maintenance tasks such as filament changes, nozzle cleaning, Bowden tube cleaning, and printing bed cleaning.
It doesn't take long to learn how to print in 3D but it's good to get a good idea of the time it takes to print in 3D. Because there are so many different scenarios you may face in 3D printing, it would be virtually impossible to think of a particular number of hours it would take you to learn it without knowing factors such as your current knowledge, the 3D printer you intend to use, and its purpose.
