Abstract
A filament for 3-D printing of chewable toys and treats suitable for dogs and other domestic animals is made by preparing a mixture of plasticized thermoplastic with reinforcement agent, lubricating agent and preservative and then extruding the prepared mixture to form a filament. Embodiments may further include aroma enhancers, flavoring additives and nutritional additives in the mixture, alone or in combination.
