Printmakers: Instructional videos are two-a-penny but not on this subject and not with this level of clarity. Acrylic sheets may not be everyone’s choice but are fairly cheap and can be sent for recycling.
Belinda Del Pesco is an accomplished printmaker, her YouTube channel has 40 instructional videos.
It is possible to do intaglio printmaking with simple equipment and Handprinted have produced instructions for exactly that using the X-Cut Express (die cutter beloved of card makers and some printmakers). Drypoint printing being an intaglio process requires more pressure than relief print but good results are possible. I have also used sticky-back aluminium foil stuch down on acrylic sheet then engraved using a rounded tip tool so as not to tear into the foil.
These are all etched on acrylic.
