Definitions

• Print setting selection system 100 may generate from the printable 3D object model a print job with print settings associated to object portion 116 based on the specifically selected print setting. In some cases, it might be required that print setting selection system 100 transform object geometrical data into a valid printable 3D object model. Generally, how object geometrical data is transformed depends on the particular type of 3D printing system to print object 106. Examples of transformation of a 3D object model into a valid printable 3D object model are illustrated in the US application with application serial number US2011/0087350, which is incorporated herein by reference to the extent in which this document is not inconsistent with the present disclosure, and in particular those parts thereof describing transformation of 3D models into a valid printable model.
• Memory 402 is shown to include an operating system 408 and applications 410.
• Operating system 408 represents a collection of programs that when executed by processor 404 serve as a platform on which applications 410 can run. Examples of operating systems include, but are not limited, to various versions of Microsoft's Windows® and Linux®. Applications 410 represent program instructions that when executed by processor 404 function as an application that provides 3D model data to print setting selection system 100. Applications 410, when executed, may also function as a service that enables a user to generate or modify 3D model data.
• Design of a manufactured object may start from 3D model 806, which includes an object formed by parallelepiped 802 and hole 804.
• FIG. 8 illustrates cross-sections of objects 800, 808, 810.
• Objects 808, 810 illustrate manufactured objects using conventional techniques for 3D printing, which, for the sake of illustration, do not provide for a specific selection of a print setting for an object portion. Therefore, design of the object bodies of objects 808 and 810 is restricted to a uniform density. More specifically, object 808 is designed with a relatively high density of object body 812 to provide a robustness sufficient to enable generating a thread at the interior wall of hole 804. However, design of object 808 requires a relatively high material usage as well as a relatively high object weight. Object 810 is designed with a relatively low density of object body 810 to keep material usage and object weight low. However, due to its low body density, design of object 810 increases the risk of object breakage during generation of a thread at the interior wall of hole 804.
• FIGS. 5A-6 show specific orders of execution, the order of execution may differ from that which is depicted.
• the order of execution of two or more blocks may be scrambled relative to the order shown.
• two or more blocks shown in succession may be executed concurrently or with partial concurrence. All such variations are contemplated.
