Laminated manufacturing (LM).

Selective Deposition Lamination
	Invented in 2003 by MacCormack, SDL must not be confused with laminated object manufacturing (LOM) technology. LOM uses a laser, laminated paper and an adhesive that fixes the model and support material.; The SDL technique works by depositing an adhesive in the area required, both of the model and the support, and a blade that cuts the outline of the layer [7].
	LOM: The layer thickness is 0.165 mm. The maximum model size is 170x220x145 mm.; SDL: Layer thickness corresponds to the thickness of the paper used plus that of the layer of adhesive.
	Sheets of PVC with the following properties are used: tensile strength: 40-50 Mpa; elongation at rupture: 30-100%; flexural modulus: 1200-200 Mpa; deformation under load temperature: 45-55°C.
	Advantages and disadvantages; Pieces of high quality aesthetic objectives are obtained. The starting materials are low cost. The pieces obtained can be painted. The equipment is of average cost. No functional parts are obtained.
