It's interesting that you do both electronic and chemistry . Plz also made informative video on uv curable pcb solder mask how it's works and how it's made ?

Also, a fourth reason for making your own PCB is that in most of the developing world - it is still costly to get PCB for hobby usage - shipping costs the bulk of the money. I've been in search of the process that would allow me to make a homemade PCB without a laser printer (as they are costly)

A permanent ink marker or pen is enough to protect copper against the etchant. But you need to be precise enough to draw the entire artwork. With through hole components it's doable, with SMD it starts getting really hard. The ink can usually be removed with acetone after etching.
