Selective deposition with lamination ( Selective Deposition Lamination - SDL ) is one of the 3D printing technologies.
Selectively
This is perhaps the most important word in the acronym and refers to the selective method the printer uses to place glue between layers of paper. Self-adhering drops are distributed with a high density in the places from which the model will be created. During this time, in other places, which serve as a support, the glue will be distributed with a lower density. Thanks to this selective process, the part of the paper that served as a support is removed quickly and easily after the printing is finished.
In the old LOM technology, everything was glued at the same intensity, including the support material around the model. At the same time, removing the support material turned into a pain that often led to the breaking of the model.
Deposition
Deposition refers to the method of applying glue in the form of droplets on a sheet of plain paper. Wherein it is taken into account that a certain part of this paper is cut, and so the process is repeated for each sheet of paper.
This process is quite different from LOM technology. Here, the glue is applied to the previously placed material and applied over the entire surface before cutting.
Lamination
Lamination is a word that describes the process of successively stacking materials, in this case ordinary office paper. This paper is glued together to produce a final, healthy and sustainable product. Although the printed prototypes are made of plain paper, they are extremely durable and do not need to be reinforced. You can use them safely as soon as they come off the printer. The models are not fragile and will not be damaged or broken if dropped. You can also drill them, carve them, manipulate them in various ways and even make them waterproof with just one dip in varnish (sealant).
