Dutch designer Rein van der Mast 3D prints bronze Pjotr fountain pen with an Ultimaker
Dutch designer Rein van der Mast (also known as Pjotr) is at it again with a new 3D printed fountain pen, but this time he’s taking the technology into his own hands. The exquisite writing instrument was printed with an Ultimaker using a bronze filament from ColorFabb, and posted just recently on van der Mast’s website.
