Embodiment Construction

[0036] definition

[0037] For the purposes of this specification and the appended claims, unless otherwise indicated, all numbers expressing amounts of ingredients, percentages or ratios of materials, reaction conditions and other numerical values ​​used in the specification and claims are to be understood as is modified in all instances by the term "about". Similarly, when values ​​are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms another embodiment of + / - 10% of the stated value. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and appended claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed...

Abstract

Computer implemented methods of producing a bone graft are provided. These methods include obtaining a 3-D image of an intended bone graft site; generating a 3-D digital model of the bone graft basedon the 3-D image of the intended bone graft site, the 3-D digital model of the bone graft being configured to fit within a 3-D digital model of the intended bone graft site; storing the 3-D digital model on a database coupled to a processor, the processor having instructions for retrieving the stored 3-D digital model of the bone graft and for combining a carrier material with, in or on a bone material based on the stored 3-D digital model and for instructing a 3-D printer to produce the bone graft. A layered 3-D printed bone graft prepared by the computer implemented method is also provided.

Description

Background technique [0001] Three-dimensional (3D) printing is an additive printing process used to make three-dimensional solid objects from digital models. 3D printing technologies are considered additive processes because they involve the application of successive layers of material. [0002] 3D printing technology is used in various industries for manufacturing and planning. For example, the automotive, aerospace and consumer goods industries use 3D printing to create prototypes of parts and products. 3D printing is also being used in the construction industry to print structural models. The use of 3D printing in private and government defense is also growing rapidly. [0003] Traditional 3D printing allows objects to be created by depositing materials one layer at a time onto a flat manufacturing platform. Once the first layer is deposited, a second layer is deposited on top of the first layer. Repeat the described process as necessary to create multi-laminated solid...
