Methods for producing spatial objects are disclosed. The methods generally include printing a spatial object, in an amorphous phase, using a three-dimensional (3D) printer and a printing material that consists essentially of polyaryletherketones. The methods further entail placing the spatial object in a container and submerging the spatial object in a suitable charging material. Next, vibrations are applied to the container that includes the spatial object and charging material. The container, charging material, and spatial object are then heated until the spatial object transitions into a semi-crystalline phase (at which point the spatial object can be removed from the container and charging material).
