YouTuber Emily The Engineer has transformed an old 3D printer into a tattoo machine, bypassing its firmware and equipping it with a tattoo gun. This innovative move comes with a built-in panic lever to ensure safety.

She explains her journey through an experimental process, highlighting the unique challenges of tattooing on curved surfaces. This modification allows the machine to print a design onto a volunteer’s leg. After several trials and some custom adjustments, Emily successfully completed the procedure, with the volunteer, Dan, expressing that the sensation wasn’t as bad as anticipated.

Good job, everyone. While the result may not be a futuristic masterpiece, it’s notable for its adventurous spirit in tech innovations. Watch Emily’s full transformation on her YouTube channel.
