Painting custom lego minifigures/parts

Hi, I’ve been thinking about making custom lego for a while, and I’ve been torn between pas pad printing (the official technical lego uses to print) or UV printer. Both machines are expensive, though UV printing is more easy/ready to use. What stopped me (beside the price) is that we can’t print with metallic ink. And then I had an idea: Why not use a cutting machine to create stencil transparent stickers, and then use a pad (just the silicon part from the pad printer) to apply paint made...
