摘要： 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.

摘要： One method of forming a part includes deforming a shape memory polymer from a permanent shape into a temporary shape, where the permanent shape of the shape memory polymer is a predetermined part shape and the temporary shape is a shape larger than the predetermined part shape. The shape memory polymer in each of the permanent shape and the temporary shape defines a cavity therein. The method further includes introducing a molding material into the cavity of the shape memory polymer, and reverting the shape memory polymer back into its permanent shape. Other methods for forming the part are also disclosed herein.

摘要： 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.

摘要： A medical cast and methods of using the same are disclosed. The method of making includes providing a shape memory polymer (SMP) in a permanent shape which corresponds to a limb's general shape but has a diameter smaller than the limb's diameter. The SMP is converted from the permanent shape into a primary temporary shape, which has a diameter larger than both a diameter of the permanent shape and a diameter of the limb. The limb is at least partially surrounded with the SMP in its primary temporary shape. The SMP is then heated, which causes the primary temporary shape to i) attempt to revert to the permanent shape, and ii) conform to a secondary temporary shape having a diameter smaller than that of the primary temporary shape and larger than that of the permanent shape. The SMP in the secondary temporary shape conforms to the limb.

摘要： A molding method includes inserting a preform having a predetermined part shape into an external mold having the predetermined part shape. The preform has therein a perforated shape memory polymer mandrel in its temporary shape, and a bladder positioned within the perforated shape memory polymer mandrel. The shape memory polymer mandrel has i) the predetermined part 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 part shape. The method further includes configuring the bladder such that it substantially blocks perforations of the mandrel in its temporary shape, injecting resin into the external mold between an inner surface of the external mold and an outer surface of the preform such that the resin impregnates the preform, and curing the injected resin, thereby forming a molded part.
