If you’re thinking of the normal run-of-the-mill business cards and you’re thinking too flatland.
This is a 3D printed business card printed using two extruder heads, clear PLA, black ABS, and some special GCode to essentially laminate black text within layers of clear PLA.
I’m not even sure what I would build with this kind of tech. Although, I think it would be super awesome to build models using clear PLA to create a variation on those “bubbles in crystal created by laser” thingies you see in gift shops everywhere. Or, a white or black plastic dinosaur skeleton printed in a block of PLA “ice.”
How about a woolly mammoth? Or caveman or alien or an entire 3D scene of spaceships attacking the deathstar suspended in clear PLA?
