SDL (Selective Deposits Layer): 3D Printing with Paper and Lasers

Selective Deposition Lamination (SLD) is a 3D printing process using paper. This process is similar to Laminated Object Manufacturing (LOM) rapid prototyping method. The process involves layers of adhesive coated paper (or plastic or metal laminates) that are successively glued together with a heated roller and cut to shape with a laser cutter layer by layer. A roller with the material moves each new sheet of material over the last and repeats the process until the object is completed.

Materials to 3D print using this process is relatively low cost since you can use off the shelf copy paper from any office store. Since 3D printed models from paper have wood like characteristics, they can be further processed using some wood finishing techniques.

It differs from Lost Object Manufacturing in a couple regards, Most notably in the gluing process. SDL adheres only the parts of the object that will fabricate the object, whereas LOM glues the entire sheet uniformly.

More information regarding SDL is available on the page dedicated to 3D printing technologies.
