A tooling system may include an outer mold line (OML) tool and one or more inner mold line (IML) tools. The OML tool may have an OML tool surface. Each one of the IML tools may have an IML tool surface and may be receivable within the OML tool 202. Each IML tool may be formed of expandable material. Each IML tool may apply an internal compaction pressure to a composite assembly positioned between the OML tool surface and the IML tool surface when the expandable material is heated.

Apparatus and methods are described for manufacturing contact lenses employing dissolvable mold structure. The apparatus and methods involve approaches to dissolve at least portions of a mold and to separate a lens from the mold to present the lens for collection.

Disclosed herein are kits for use in adding degradable foam to a tire, methods for preparing a degradable foam-containing tire, tires containing degradable foam, and methods for degrading the degradable foam in tires containing degradable foam. The degradable foam comprises a combination of (i) at least one di- or polyisocyanate, (ii) at least one polysiloxane diol, at least one polysiloxane diamine, or a combination thereof, and (iii) optionally at least one polyol.

A coated tubular construct for biological and industrial applications includes a plurality of channels, where each channel is radially surrounded by a wall comprising a first polymer, and a conformal coating comprising a second polymer is disposed on an outer and/or an inner surface of each wall. A method of producing a tubular construct includes 3D printing a template structure comprising a sacrificial material and a photoinitiator, and immersing the template structure in a first prepolymer solution comprising a first prepolymer and a co-initiator. During the immersion, the template structure is exposed to light, and the first prepolymer undergoes radical polymerization to conformally coat the template structure with the first polymer, forming a coated template. The sacrificial material is removed from the coated template, and a tubular construct comprising the first polymer is formed.

Fibrous materials, compositions that include fibrous materials, and uses of the fibrous materials and compositions are disclosed. For example, the fibrous materials can be operated on by a microorganism to produce ethanol or a by-product, such as a protein or lignin.

A dispersible non-woven article, and methods of making the same. The dispersible non-woven article includes a web of fibers and a dried binder having a plurality of ultrasonic energy treated portions and a plurality of non-ultrasonic energy treated portions. The web of fibers has a basis weight of from about 10 gsm to about 150 gsm. The dried binder comprising a polymer having at least one functional group that is reactive with the fibers. The fibers have at least one functional group that is reactive with the polymer. The article has a cross direction wet tensile strength that is developed by the ultrasonic welding. The article is flushable.

In 3-D printing a platen moves toward an intermediate transfer belt (ITB) to have a sheet positioned on the platen contact the ITB to electrostatically transfer a layer of different materials to the sheet, and then the platen moves to a heater to join the layer to the sheet. This processing is repeated to have the sheet repeatedly contact the ITB (with intervening heating at the heater) to successively form layers of the materials on the sheet. The sheet having the layers thereon moves to a rinsing station, where a liquid is applied to dissolve the sheet and leave a freestanding stack of the layers. The freestanding stack is fed to a platform to successively form a 3-D structure of freestanding stacks of the layers. Light and/or heat are applied to the 3-D structure to bond the freestanding stacks to one another on the platform.

In 3-D printing a platen moves toward an intermediate transfer belt (ITB) to have a sheet positioned on the platen contact the ITB to electrostatically transfer a layer of different materials to the sheet, and then the platen moves to a stabilization station to join the layer to the sheet. This processing is repeated to have the sheet repeatedly contact the ITB (with intervening stabilization at the stabilization station) to successively form layers of the materials on the sheet. The freestanding stack is fed to a platform to successively form a 3-D structure of freestanding stacks of the layers. Heat and/or pressure and/or light are applied to the 3-D structure to bond the freestanding stacks to one another through the sheets of collapsible media on the platform.

A three-dimensional-object forming apparatus generates a three-dimensional object such that from a formation intermediate product obtained by sequentially depositing unit layers each including a curable build material and/or a curable support material, a support made of the support material is removed. The apparatus includes a stage, an ejection unit, a curing unit, and a composite arranger. On the stage, a multilayer structure of the unit layers is placeable. The ejection unit ejects the build and support materials toward an uppermost surface of the multilayer structure while moving relative to the stage. The curing unit cures the build and support materials on the uppermost surface. The composite arranger controls the ejection and curing units, when the support includes a foundation between the object and the stage, to cause the build and support materials to coexist in a lowermost surface region of the object contacting the foundation.

Simulated anatomical components, such as simulated vascular vessels, produced by a method that includes forming an anatomical component mold from a soluble polymer such that the mold defines an interior void of the simulated anatomical component. One or more layers of an elastomeric material is applied around the anatomical component mold and the material is allowed to cure to form a wall of the simulated anatomical component. At least a portion of the mold is dissolved to form a passage for liquid within the simulated anatomical component. Simulated anatomical components are connectable to other components of a surgical simulation system and can be modularized.
