The question of "why" is important here.
One could make a LED bulb by buying a E27 "plug", an LED, making a PCB with the power supply for the LED, putting that together and attaching a cover of some sort. It will be one to two orders of magnitude harder to make than an LED bulb made serially.
I don't know much about processes needed to make a filament bulb (at the very least that requires working with glass, but I don't even know in which order such bulbs get assembled).
So, if you just want a working bulb, I'd probably buy one. That need not be the case if you want to figure out how to make a bulb and are fine with having to make a few of them before they are good enough (because you'll learn about random important things along the way).
(Oh, and don't even try to make fluorescent bulbs. They are nasty in all ways I can think of -- require nasty gases inside, high voltage, can produce UV incl. UVC that needs to be filtered out lest they damage eyes of anyone nearby pretty quickly, ...).
