3D printers are changing the world, for good and ill. Doctors can now 3D-print replacement bones perfectly customized to their patient’s anatomy while terrorists could potentially print untraceable automatic weapons. In between these extremes are projects like 3D-printed graffiti by artist Greg Petchkovsky. Some might consider it a next-gen nuisance, while others see it as the evolution of an art form.

Petchkovsky’s graffiti is minimal and almost purposefully invisible. He finds architectural details that have suffered damage and designs 3D-printed “prosthetics” that attempt to fix them — but with a surprise twist. A broken corner of a sandstone staircase reveals a Lego skeleton; meanwhile, pitted clay bricks appear to melt, an homage to old-school “drip” style tags.
