Problems solved by technology

[0003] Although the use of supports in 3D printing allows the printing of objects with more complex structures and designs, it suffers from certain disadvantages
Because supports are printed with the object, they tend to result in a lot of excess material being used during the build
This excess material can be costly and in many cases cannot be reused or recycled
Also, building supports next to the object may also prolong the time it takes to print the object
In some cases, the time involved in building the support may exceed the time required to actually fabricate the object itself

Embodiment Construction

[0022] Embodiments of the present application relate to the use of prefabricated support structures in 3D printing. These supports may be full model contact supports used in deposition and extrusion based 3D printing techniques, supports that are finally removed from the finished object. In some embodiments, supports may be scaffolding, lattice or lightweight structures or other support configurations known in the art. Several benefits to the 3D printing process are realized by fabricating and utilizing prefabricated support structures. For example, utilizing the prefabricated supports disclosed herein results in reduced or even eliminated material waste. This material savings stems from the ability to use prefabricated supports to make multiple parts rather than just a single part. Prefabricated supports can also improve the performance and use of single-nozzle 3D printers. This is because using pre-made supports allows the single nozzle printer to extrude different materi...

Abstract

The embodiment of the invention relates to optimized three-dimensional printing using a manufactured upholder, and discloses a system and a method for supporting a to-be-printed object in an additive manufacturing process. An upholder structure is pre-manufactured and positioned in a construction area of 3D printing equipment before the 3D object is printed. When the object is printed, the upholder is removed and the upholder structure is re-positioned in the construction area of additive manufacturing equipment for being reused for printing another object.

Description

technical field [0001] This application relates to 3D printing using object supports. More specifically, the present application relates to systems and methods for designing, creating, using and reusing supports to create objects using 3D printing. Background technique [0002] When 3D printers are used to print objects, they often include areas that are not self-supporting when they are printed. These areas are often referred to as dangling objects. In general, overhangs are those areas in an object that due to their angle will break or sag because they lack sufficient support from the previous layer. In current 3D printing applications, supports are usually added to the 3D model before printing, and their suspensions are printed together with the printed object. Once the object and support have been printed and the printed material has hardened or hardened, the support is removed or separated from the object. [0003] Although the use of supports in 3D printing allows ...
