A method of fabricating a conformally coated article from an assembly that is housed in a vacuum chamber of a fabrication device; wherein the vacuum chamber contains an applied vacuum; wherein the assembly comprises a preformed lamination layer and an object having a surface in need of lamination; wherein the preformed lamination layer has a first surface and a second surface opposite the first surface, and a heat-softened middle portion at a first temperature and surrounded by an edge portion; wherein the object has a first surface and a second surface opposite the first surface, and the first surface being in need of lamination and comprising an inner portion and a perimeter portion surrounding the inner portion; wherein the assembly is configured such that the first surface of the preformed lamination layer is positioned facing the first surface of the object, wherein the edge portion of the preformed lamination layer forms a gastight seal to the perimeter portion of the first surface of the object such that the assembly contains a gastight inner region defined by a combination of the gastight seal, the first surface of the preformed lamination layer and the first surface of the object, wherein the heat-softened middle portion of the preformed lamination layer is spaced apart from the inner portion of the first surface of the object by the gastight inner region, and wherein the gastight inner region contains a reduced gas pressure; wherein the applied vacuum in the vacuum chamber is effectively equal to the reduced gas pressure in the gastight inner region of the assembly; and wherein the method comprises: conforming the heat-softened middle portion of the preformed lamination layer to the inner portion of the first surface of the object by increasing gas pressure within the vacuum chamber such that the gas pressure within the vacuum chamber is greater than the reduced gas pressure within the gastight inner region, thereby conformally pushing the heat-softened middle portion against the inner portion of the first surface of the object so as to fabricate the conformally coated article; wherein the conformally coated article comprises a conformed lamination layer and the object, wherein the conformed lamination layer is formed from the preformed lamination layer and has a first surface and a second surface opposite the first surface, and a middle portion and an edge portion surrounding the middle portion; wherein the object has a first surface having an inner portion and a perimeter portion surrounding the inner portion, wherein the inner portion of the first surface of the object is conformally coated by the middle portion of the conformed lamination layer; and wherein the edge portion of the conformed lamination layer forms a gastight seal to the perimeter portion of the first surface of the object, wherein the middle portion of the preformed lamination layer is heated in one heating step, characterized in that prior to the conforming step, sealing, under the applied vacuum, the edge portion of the preformed lamination layer to the perimeter portion of the first surface of the object by contacting the edge portion of the preformed lamination layer to the perimeter portion of the first surface of the object so as to form the gastight seal and the gastight inner region of the assembly, wherein during the contacting the edge portion of the preformed lamination layer is being heat-softened at a second temperature, wherein the first and second temperatures are the same or different. conforming the heat-softened middle portion of the preformed lamination layer to the inner portion of the first surface of the object by increasing gas pressure within the vacuum chamber such that the gas pressure within the vacuum chamber is greater than the reduced gas pressure within the gastight inner region, thereby conformally pushing the heat-softened middle portion against the inner portion of the first surface of the object so as to fabricate the conformally coated article; wherein the conformally coated article comprises a conformed lamination layer and the object, wherein the conformed lamination layer is formed from the preformed lamination layer and has a first surface and a second surface opposite the first surface, and a middle portion and an edge portion surrounding the middle portion; wherein the object has a first surface having an inner portion and a perimeter portion surrounding the inner portion, wherein the inner portion of the first surface of the object is conformally coated by the middle portion of the conformed lamination layer; and wherein the edge portion of the conformed lamination layer forms a gastight seal to the perimeter portion of the first surface of the object, wherein the middle portion of the preformed lamination layer is heated in one heating step, characterized in that prior to the conforming step, sealing, under the applied vacuum, the edge portion of the preformed lamination layer to the perimeter portion of the first surface of the object by contacting the edge portion of the preformed lamination layer to the perimeter portion of the first surface of the object so as to form the gastight seal and the gastight inner region of the assembly, wherein during the contacting the edge portion of the preformed lamination layer is being heat-softened at a second temperature, wherein the first and second temperatures are the same or different.
