    Abstract: A method for making a preform includes creating a pressure differential between an inside and an outside of a perforated shape memory polymer mandrel in its temporary shape. The pressure differential is such that pressure outside the perforated shape memory polymer mandrel is greater than pressure inside the perforated shape memory polymer mandrel. The perforated shape memory polymer mandrel has i) a predetermined preform shape as the temporary shape and ii) a shrunken shape as its permanent shape, wherein the shrunken shape is configured such that it is removable from the predetermined preform shape. The method further includes depositing, as the pressure differential is maintained, at least one material onto a surface of the perforated shape memory polymer mandrel. The at least one material is set in the predetermined preform shape, thereby forming the preform.

    Abstract: A method disclosed herein includes packaging and de-packaging a part. The part is packaged by placing the part adjacent to a shape memory polymer (SMP) while the SMP is in a permanent shape. The SMP is heated to a temperature above a switching temperature of the SMP, and a force is applied to the heated SMP such that it conforms to i) a shape of the part and/or ii) a desired shape for packing the part, thereby changing the SMP from the permanent shape into a temporary shape. The SMP is cooled to a temperature below the switching temperature to set the SMP into the temporary shape. The part is de-packaged by heating the SMP to a temperature above its switching temperature, thereby reverting the SMP from the temporary shape into the permanent shape and releasing the part. The part is removed from the SMP in the permanent shape.

    Abstract: A method of forming a part with a feature having a die-locked geometry is disclosed herein. A molding tool used in the method includes at least one die having a cavity defined in a surface thereof, and a protrusion formed in the cavity. The method includes disposing a shape memory polymer insert on the protrusion, where the shape memory polymer insert has i) the die-locked geometry as its temporary shape, and ii) a geometry that is removable from the die-locked geometry as its permanent shape. A material is established in the cavity such that at least a portion of the material conforms to the die-locked geometry, thereby forming the part having the feature with the at least one die-locked geometry.
