Abstract: The present disclosure is directed to additive manufacturing systems, components therein, and methods for their use. The additive manufacturing system comprises a powder material handling system comprising a virgin powder inlet. The virgin powder inlet is coupled to a virgin powder drum and configured to receive a virgin powder from the virgin powder drum. The additive manufacturing system further comprises a liquid material handling system comprising a binder inlet. The binder inlet is coupled to a binder drum and configured to receive a binder from the binder drum. The additive manufacturing system also comprises an additive manufacturing machine coupled to the powder material handling system and the liquid material handling system. The additive manufacturing machine receives the virgin powder and the binder from the powder material handling and liquid material handling systems and is configured to manufacture a work product using the virgin powder and the binder.

Abstract: An insole for footwear which includes a layer (11) of resilient plastics material shaped so as to provide support for the metatarsal region (at 14) or the valgus region (at 16) of the foot, or both, and having a covering 12 of cloth or other suitable material secured to its upper surface, wherein the upper surface of the plastics material has a number of depressions (18 and 18a) in each of which can be fitted an insert (19 or 19a) so that the user can adapt the insole to suit his or her particular foot condition by omitting an insert (19 or 19a) from any depression (18 or 18a) which corresponds to the position of a sensitive spot on the user's foot.
