3D printers have been with us for decades, routinely turning 3D computer designs into detailed physical objects for product design, education, architecture, healthcare, mapping, historic preservation and other applications. These devices create models in a range of materials, including plastic, plaster, photopolymers, metal and sometimes even food. Each of these materials brings inherent advantages and disadvantages, depending upon your application. There’s one more to consider: paper.
This white paper will explain how a paper-based 3D printer creates a physical 3D model using the SDL process and will document the unique attributes of Clean- Green3D’s CG-1 3D printer.
Selective Deposition Lamination (SDL) 3D printing was invented by Dr Conor and Fintan MacCormack in 2003.
SDL is not to be confused with the laminated object manufacturing (LOM) technology. LOM used a laser, laminated paper and glue, so everything was glued together, including the support material around the model. Excavating the model was an ordeal, often resulting in 3D part breakage. The CG-1 uses a blade for the cutting and selectively deposits the adhesive only where it’s needed.
