An apparatus, method and manufacture utilizes additive manufacturing techniques to produce architectural manufactures such as windows and doors. The manufactures may have a composite construction and may feature inclusions like metal plates and reinforcements. The model used for controlling the manufacturing process may be derived from digital scanning of the structure on which the manufacture is used. Optionally, a finite element analysis is used to test the model and alter it in response to stress and/or thermal requirements.
