Problems solved by technology
However, in large-scale additive manufacturing, such support structures consume a lot of resources, such as material, printing time and energy consumption
Furthermore, the properties of the support structure cannot be flexibly selected, so removing the support structure can be difficult
Even if a support structure is printed using a sparse fill pattern, it can still be difficult to remove the support structure, and the problem of printing across gaps in a sparse fill support structure discussed above still exists

Embodiment Construction
[0107] figure 1 An exemplary system 100 for additive manufacturing is shown. System 100 may include a 3D printer configured to print object 200 by extrusion deposition (or material extrusion). Printhead 120 is shown including nozzles configured to deposit one or more polymer layers onto print substrate 140 to form object 200 . Print substrate 140 in figure 1 is shown to provide a printing surface 110 for receiving initial printing material deposited from a printhead 120 .
[0108] Print substrate 140 is shown including print bed 160 . Print bed 160 may provide a uniform or flat surface. Print bed 160 may include heated and / or unheated stages. Print substrate 140 may include any alternative type of print bed as well as any other intermediate structure (not shown) that at least partially covers the print bed. The stacking direction of the layers is the z direction, and the printing direction is the x direction.

Abstract
An additively manufactured structure and methods for making and using same. An object (200) can be printed at least partially on an attachment portion (240). The attachment portion can be bonded to the object upon the printing. The object does not need to be removed from the attachment portion. The need of providing a print surface (110) to allow easy removal of the object is eliminated. The object can be a flat panel and can eliminate the need of printing a large flat layer using additive manufacturing. The attachment portion can be cut prior to the printing, so no trimming needs to be performed after the printing. The attachment portion can be made of a material that has one or more selected properties to expand functionalities of the object. A secondary operation for attaching the attachment portion to the object after the printing can be eliminated.
Description
[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application Serial No. 62 / 683,527, filed June 11, 2018. Priority to this Provisional Patent Application is expressly claimed, and the disclosure of this Provisional Patent Application is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The disclosed embodiments relate generally to additive manufacturing, and more particularly, but not exclusively, to additively manufactured structures and methods of manufacturing the same. Background technique [0004] Three-dimensional (3D) printing, also known as additive manufacturing, is a technique that deposits material only where it is needed, and thus differs from traditional manufacturing techniques that typically form parts by reducing or removing material from bulk material. Significantly less than material waste. While the initial three-dimensional (3D) printed articles ...
