An additive elastomeric manufactured part having an elongation at break of at least 50% may be made by a method comprising the following. A material comprising a prepolymer and filler is first dispensed through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the material so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base. Subsequent layers are then formed on the initial layer by repeating the dispensing and movement on top of the initial layer and layers that follow.

A process for purification of a carbon dioxide feedstock that includes carbon dioxide and gaseous and liquid C+ hydrocarbons. Specifically, a carbon dioxide feedstream is passed through one or more separation unit, each separation unit removing one or more C+ hydrocarbon from the carbon dioxide feedstream to provide a richer carbon dioxide gas stream. The one or more separation unit employs an adsorption media and has an adsorption step and a media regeneration step.

The inventions is directed to a method for recovering support materials used in an additive manufacturing process. The method comprises exposing a precursor additive manufactured article comprised of a water soluble support polymer and an insoluble material to water. The water soluble support polymer is dissolved in the water. The remaining article is then removed from the water. The dissolved water soluble polymer is precipitated from the water. The precipitated polymer is separated from the water and any remaining water removed to recover the water soluble support polymer. The recovered water soluble support polymer may then be re-used to make further additive manufactured articles.
