摘要： A method for fabricating a custom cranial remodeling device for correction of cranial deformities in a subject is described. The method comprises generating a three-dimensional head data file for the subject and determining contour lines on the head. The method further comprises automatically generating a modified head shape data file and juxtaposing the modified head shape with the head represented by the three-dimensional head data file having the contour lines thereon. Still further the method includes utilizing the modified head shape data file to generate a shape for a desired custom cranial remodeling device, the shape having an interior surface to contact the head and an outer surface. The method also includes projecting lines outward from the contour lines to the outer surface and utilizing the projected lines to establish cranial remodeling device contour lines for the custom cranial remodeling device.

摘要： A system includes a memory module configured to store a computer model of a part for manufacturing with an additive manufacturing machine, and a processor communicatively coupled to the memory module. The processor is configured to receive the computer model, discretize the computer model into a mesh, predict a deformation behavior the plurality of nodes of the mesh under a simulated sintering process, determine a buckling factor for the part based on the predicted deformation behavior of the mesh, determine whether the buckling factor exceeds a threshold, in response to determining that the buckling factor exceeds the threshold, export the computer model to the additive manufacturing machine for pre-build processing, and in response to determining that the buckling factor does not exceeds the threshold, output, to a display of the system, at least one of an alert that the part is unstable or the buckling factor.

摘要： Systems and methods for fabricating indirect bonding trays are disclosed. Physical models of a patient's teeth can be created with non-functional placeholder brackets, impressions of which can be transferred to indirect bonding trays. This can create wells in which functional brackets can be placed into, reducing errors created from transferring functional brackets from the physical model onto the indirect bonding trays.

摘要： A method (1100) of fabricating a personalised orthopaedic cast (900) is disclosed. The method (1100) includes 3D scanning of a body part of a user, generating a Computer Aided Design (CAD) of an orthopaedic cast (900) for the scanned body part, and simulating real-life conditions to determine mechanical stability of the modelled cast. The mechanical stability is determined through Finite Element Analysis (FEA). The method (1100) includes determining whether the mechanical stability of the modelled cast is acceptable. The method (1100) includes finalising the CAD model when the mechanical stability of the modelled cast is found to be acceptable. The method (1100) includes 3D printing the finalised CAD model to fabricate the personalised orthopaedic cast (900).
