On your next trip to DC, check out the 12-foot-high replica of the U.S. Capitol dome and rotunda in the monument’s visitor’s center.

It is the result of expert Stereolithography by Metro Rapid Prototyping. The Indiana-based service bureau worked with a model-making firm to design, build and cast the Capitol.

The Time Compression magazine article says that “the five-month mold making and casting process involved five SLA machines from 3D Systems (www.3dsystems.com; Rock Hill, SC) churning out the masters nearly continuously, with smaller parts taking up to a day and some intricate pieces requiring a week to construct in meticulous layers.”
