Making New Things Old 3D Printing Replaces Craftsmanship

 It’s a sad fact that the artisans and craftspeople who created some of the most  beautiful, distinctive interior and exterior architectural elements for  residential buildings are an endangered species. The proliferation of sleek,  glass-and-steel architecture, combined with the rising cost of materials and  labor have made the ornate, heavily-ornamented facades and interiors of prewar  buildings truly things of the past. Now, the stonemasons, sculptors, and other  craftspeople are aging or gone; fewer and fewer are taking up their trades as  demand for them has dwindled.  

 “Stonemasons that used to carve stone,” says Joakim Aspegren, a principal with New York City-based Architecture  Restoration Conservation, PC, “That type of person is very hard to find nowadays. There’s not as great a need as there used to be fifty or a hundred years ago.”  

 The Age of 3D

 While the near-extinction of architectural artisans themselves is cause for  concern, there is a silver lining here. The availability and affordability of  old-fashioned architectural elements is changing, thanks to new technology and  so-called '3D printing' that enables designers and architects to use digital  imaging software and cutting-edge fabrication techniques to create not only  exact replicas of ornate cornices, moldings, and other building elements, but  to create them from scratch, custom-built for brand new construction projects.  Indeed, in the future, the technology may be used to diversify and enrich  residential architecture in ways that up to now have been cost-prohibitive.  

 The diversity of American architecture, from the ornateness of the early  twentieth century, the celebration of modernism in Art Deco and contemporary  styles in later decades gives urban centers their personalities. And preserving  the older buildings has a great deal to do in maintaining that diversity. The  artists who restore building elements, whether using 3D printing or more  traditional methods, provide the elaboration that collectively makes cityscapes  as interesting as they are today.  

 The technology has not made huge waves in the Chicago architecture preservation  scene yet, but firms and entrepreneurs across the country are starting the  process. With the city's vast historical housing stock, Chicago may soon be a  large market for the application of this technology.
