Abstract: A method of designing and engineering a building element (e.g., a staircase) that is structurally verified and may be easily certified. The method uses a parametric three-dimensional (3D) model of the building element and a constraint space definition. It ensures that the building element will fit in the building and will comply with functional, legal, and/or other requirements, such as strength, dimensional requirements, or use of certain materials. A computer system provides a user tool for easily amending the building element while visualizing it in its specific use. It also converts the amended building element to processing instructions for 3D manufacturing, such that the end product complies with the constraint space definition. A user without extensive knowledge of engineering, complex computer-aided design (CAD) programs, or 3D manufacturing can easily amend a design to his or her personal need and have the building element custom produced.

Abstract: An additive manufacturing machine includes a build platform being movable along a build direction and a powder supply assembly for dispensing additive powder above a build plane. A recoating assembly is used for spreading the additive powder into a build layer on the powder bed. The recoating assembly includes a support beam that slidably supports a recoater blade and moves along a recoater direction over the powder bed. A blade positioning mechanism adjusts the vertical position of the recoater blade in response to measurements from a sensing device which measures a tip clearance between the recoater blade and the build plane. The tip clearance may be measured along the length of the recoater blade while stationary and while moving along the recoater direction to obtain a smooth and level layer of additive powder.
