Now here is a large 3D printer! Dirk Vander Kooij is a designer who uses a repurposed manufacturing robot as a 3D printer to extrude recycled plastic into designer furniture.
For him, the visible resolution of the printer, i.e., the beads of plastic, (rather than the smooth output from plastic molds) is a preference – he wants people to see something about how the furniture was made.
