Printed circuit boards using a photopolymer 3D printer

Nowadays, you won't surprise anyone with 3D printers. And in the last year or two, due to a strong decrease in cost, their photopolymer subspecies has also flourished. Now such a printer is already available to almost everyone and the number of their models on the market is multiplying every month.
