Carlo Borer is deliberately autodidact as an artist. He has been working freelance since 1981, beginning with figurative paintings, drawings, and three-dimensional works made of polyester and electrical light. Since 1991, he has been building objects out of stainless steel or aluminum. And in 1999, he started using 3D computer graphics to design, develop, and construct sculptures, installations, furniture and utilitarian objects, such as espresso machines, ventilators, and mailboxes. A laser is used to cut the forms out of the sheet metal, which are then rounded off and welded. Borer refers to works that have come about like this as Transformers, Loops, and Clouds. Though Borer takes his inspirations for his No Readymades and his Spaceships from pieces he has found, nevertheless, he creates the works as complex forms in virtual reality by means of CAD systems that have been further developed especially for this.
