Abstract: The present disclosure provides a method of making an additive manufactured article. The method includes: a) attaching a multilayer structure (300, 500) to a build platform (210); b) selectively curing a photocurable composition (219) that is in contact with a porous layer (330, 530) of the multilayer structure, thereby forming an object attached to the porous layer; and c) separating the object from the build platform. The multilayer structure includes an adhesive layer (310, 510), an impermeable layer (320, 520) attached to the adhesive layer, and a porous layer (330, 530) attached to the impermeable layer. The adhesive layer of the multilayer structure is attached to the build platform. The present disclosure also provides an object made by the method, and the multilayer article used in the method. Use of the multilayer article assists in improving adhesion between the build platform and the object.
