Printem: Instant Printed Circuit Boards with Standard Office Printers & Inks
summary
Printem film produces single‑sided copper PCBs using an unmodified office inkjet or laser printer, standard inks, a 30‑second UV/sunlight exposure, and a peel step. Material stack uses a UV adhesive, copper foil (craft copper from Michaels), and a Kapton or OHP top substrate; 6×6 in samples cost about <$3 per 6×6. Resulting boards are solderable (on Kapton), achieve about 0.8 mm trace widths (32 mil) in hand-made samples, and power working prototypes: an Arduino shield, a paper speaker, capacitive shortcuts, and a moisture sensor.
