It was clear that this technique could have applications in manufacturing and beyond, so Chuck promptly took out some patents and founded 3D Systems, a 3D printing company that is still alive and well today.Īn early "homemade" 3D printer prototype. The 3D printers most commonly used in the consumer sector are SLA printers, from companies like MakerBot and others. The SLA process involves pointing a UV laser at liquid photopolymer which makes it solid. In 1984, Charles "Chuck" Hull invented stereolithography (SLA), a method of 3D printing where designers create a 3D model that is then printed layer by layer into a solid, physical object. Scale Models: The Humble Beginnings (1986-2000) Prepare to be blown away by this potentially revolutionary construction technology. From plastic models on an architectural design table to habitable colonies on Mars, here’s what you’ve been dying to know about the history-and future- 3D printing in construction.
