Polylactide (PLA) parts can be crystallized via two procedures. In the first procedure, i.e. a 2-step post-mold annealing process, the complete crystallization of PLA parts can be done after molding in a secondary operation called as post-mold annealing to make higher heat-resistant PLA parts. There are limitations to this 2-step operation, namely, a) warpage of parts with complex geometries, and b) scaling up higher production volume times. In the second procedure, i.e. 1-step in-mold annealing process, the complete crystallization of PLA parts can be done in the mold itself by holding the temperature of the mold at the crystallization temperature of PLA which is about 100° C. The 1-step in-mold annealing process using a masterbatch blended with neat PLA results in a highly crystalline article produced in a significantly lower cycle time.

An example medical device includes a balloon that is inflatable to an inflated configuration. The balloon includes a non-compliant layer coextruded on an inner layer, and an outer layer coextruded on the non-compliant layer. The non-compliant layer is configured to delaminate from the inner and the outer layers in the inflated configuration. The non-compliant layer may be configured to rupture in the inflated configuration. An example technique includes inflating the balloon to a predetermined pressure sufficient to rupture the non-compliant layer and insufficient to rupture both the inner and outer layers. The example technique further includes deflating the balloon, and introducing the balloon into a vasculature. Another example technique includes coextruding a non-compliant layer on an inner layer, coextruding an outer layer on the non-compliant layer, and forming a balloon from the inner layer, the non-compliant layer, and the outer layer.

An example system for molding a photocurable material into a planar object includes a first mold structure having a first mold surface, a second mold structure having a second mold surface, and one or more protrusions disposed along at least one of the first mold surface or the second mold surface.

In an example method of forming a waveguide film, a photocurable material is dispensed into a space between a first mold portion and a second mold portion opposite the first mold portion. Further, a relative separation between a surface of the first mold portion with respect to a surface of the second mold portion opposing the surface of the first mold portion is adjusted. The photocurable material in the space is irradiated with radiation suitable for photocuring the photocurable material to form a cured waveguide film. Concurrent to irradiating the photocurable material, the relative separation between the surface of the first mold portion and the surface of the second mold portion is varied and/or an intensity of the radiation irradiating the photocurable material is varied.
