It would be interesting to try to have actual registration so that the embossed design can interact with the printed copy rather that just being an arbitrary background decoration.
The way I understand your comment is you could have a scene or objects printed on a card, then line up an embossed design over the print to create depth or imprint specific areas of the print creating various effects. That would be interesting
I like how they kept it simple and minimal. If you look into embossers, their form factor is quite different (more akin to a construction stapler).
I've been tinkering with a variation on the theme -- something that can emboss paper / cardboard / thin sheet metal. 3D printed dies work great, but it's some rabbit hole! Lots and lots to learn.
Great design. Printing without supports is faster and gives better quality surfaces.
Supports are one of the main drawbacks of FDM 3D printing, it takes a lot of effort and limits your designs. Can’t wait until 4/5-axis printers become the norm.
Make two blocks sized as business card. Extrude your graphic in one and make inverse hole of the graphic with some tolerance in the other. You will get better results that's easy to model, print and align.
Just pushing two blocks by hand and adding your weight will most likely be enough to make nice impression. The reason is that you have the inverted side - normally you would have just one plate pushing against some softer rubber so the paper has nowhere to go and you need a lot more force.
Tbh this roller design is needlesly complicated for business cards. Printing the rolls with overhangs will require supports. Roller press for graphics has some advantages like consistency of force and pressing of different sized/long pieces. None of which are useful here. Besides you wouldn't have emboss on the roll (unless you were printing infinite patterns) - you would press plate and paper through smooth roller press.
