Technical Field
The present disclosure relates to the field of 3D printing, and more particularly, to 3D printing using a dynamic build platform having one or more individually adjustable support members.
Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
The platform (also referred to as a "build platform") used with three-dimensional (3D) printers is typically a flat, fixed surface, i.e., the surface does not move during the 3D printing process (also referred to herein simply as "printing"). A first surface of a 3D printed part (also referred to herein simply as a "part") to be printed is defined as a base surface and is typically printed on and in contact with a build platform. Unsupported portions of the part spaced from the underlying surface, such as overhanging bosses, shelves, flanges, etc., may need support during printing in order to prevent the unsupported portions from sagging before curing can occur. Therefore, the support material may be printed under the unsupported portion before the unsupported portion is printed to ensure the structural strength of the part. Once the 3D printing of the part is complete, the support material must be removed and discarded. Thus, the support material is wasted in terms of the additional material required for support, the time required to print the support material, and the time to remove the support material.
The present disclosure addresses the problem of reducing the amount of support material required during 3D printing.
Disclosure of Invention
In one form of the present disclosure, a method of 3D printing a part using a dynamically adjustable support member is provided. The part has at least one portion that requires support during 3D printing, and at least a dynamically adjustable support member is moved to support the at least one portion during 3D printing of the part. The at least one dynamically adjustable support member may be moved from a retracted position to a support position after printing the first portion of the part, and the at least one portion that needs to be supported may be supported by the at least one dynamically adjustable support member in the support position. The method may comprise: 3D printing the part in a 3D printing room. In some aspects of the disclosure, the 3D printing chamber may include a base and at least one wall, and the at least one dynamically adjustable support member may include a first dynamically adjustable support member extendable from the base and a second dynamically adjustable support member extendable from the at least one wall. In addition, the at least one portion of the part requiring support may include a first overhanging portion and a second overhanging portion. During 3D printing of the part, the first overhanging portion may be printed over and supported by the first dynamically adjustable support member, and the second overhanging portion may be printed over and supported by the second dynamically adjustable support member.
In one aspect of the disclosure, the first dynamically adjustable support member may be moved from a retracted position to a support position after printing the first portion of the part, and the first cantilevered portion may be supported by the first dynamically adjustable support in the support position. In another aspect of the disclosure, the second dynamically adjustable support member may be moved from a retracted position to a support position after printing the second portion of the part, and the second overhanging portion may be supported by the second dynamically adjustable support in the support position.
The method may comprise: 3D printing a first portion of the part; moving the first dynamically adjustable support member from a retracted position to a support position after printing the first portion; and 3D printing the first overhanging portion of the part such that the first overhanging portion is supported by the first dynamically adjustable support member in the support position. A second portion of the part may be printed, the second dynamically adjustable support member may be moved from a retracted position to a support position, and the second overhanging portion of the part may be printed such that the second overhanging portion is supported by the second dynamically adjustable support member in the support position. In some aspects of the present disclosure, the first overhang portion extends from the first portion, and the second overhang portion extends from the second portion.
In another form of the present disclosure, a method of printing a 3D part includes: 3-D printing a first portion of a part in a 3-D printing chamber, wherein the 3-D printing chamber comprises a first dynamically adjustable support member. The first dynamically adjustable support member moves from a retracted position to a support position after the first portion of the part has been printed, and the first overhanging portion of the part prints after the first dynamically adjustable support member has been moved from the retracted position to the support position. Additionally, the first overhanging portion of the part is supported by the first dynamically adjustable support member in the support position. The 3D printing chamber may comprise a base and at least one wall angled relative to the base, and the base and the at least one wall may each comprise at least one dynamically adjustable support member such that the first dynamically adjustable support member in the support position protrudes from the base and the second dynamically adjustable support member in the support position protrudes from the at least one wall. The first overhanging portion of the part may be printed over the first dynamically adjustable support member prior to moving the second dynamically adjustable support member from the retracted position to the support position. Additionally, a second overhanging portion of the part may be printed over the second dynamically adjustable support member after the second dynamically adjustable support is moved to the support position. In some aspects of the present disclosure, the first overhang portion extends from the first portion, and the second overhang portion extends from the second portion.
In yet another form of the present disclosure, a method of 3D printing a part includes: printing a first portion of a part in a 3D printing chamber, the 3D printing chamber having at least one wall, and the at least one wall including a dynamically adjustable support member operable to move from a retracted position to a support position. The dynamically adjustable support member is moved from a retracted position to a support position after a first portion of the part has been printed, and a second portion is printed and supported by the dynamically adjustable support member in the support position while printing. The second portion is spaced apart from the first portion, and the dynamically adjustable support member in the support position is positionable between the first portion and the second portion of the part. In some aspects of the disclosure, support material is printed on the dynamically adjustable support member prior to 3D printing the second portion of the part. In these aspects, the second portion of the part may be printed on the support material.
Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

It should be appreciated in light of the present disclosure that a method for reducing the material, time, and/or cost for printing a part is provided. The method comprises the following steps: one or more dynamically adjustable support members are extended during printing of the part so that no or reduced support material is required to support the overhanging portion of the part. As used herein, the phrase "overhanging portion" refers to a portion of a 3D printed part that is supported during printing of the part. In some aspects of the present disclosure, the overhanging portion is supported such that the overhanging portion is allowed to cure and not sag due to gravity until curing is complete. Reducing the amount of support material required to 3D print a part reduces the time required to print a part, the amount of material used to print a part, and the cost of printing a part. The one or more dynamically adjustable support members may be part of a 3D printing chamber having a base comprising the one or more dynamically adjustable support members and/or one or more walls comprising the one or more dynamically adjustable support members. The method comprises the following steps: after the first portion of the part has been printed, at least one of the dynamically adjustable support members is moved from the retracted position to the support position such that the support member does not restrict access to the first portion by the printer head. Thus, one or more overhanging portions of the part may be supported by a dynamically adjustable support member that is placed into a supporting position during printing of the part (particularly after printing of the first portion under the overhanging portions).
As used herein, the terms "upper," "lower," "above," and "below" refer to the location or position of a surface in the drawings, and not to the precise or particular orientation or position of a pointer to a surface of a part or a part formed by a method in accordance with the teachings of the present disclosure.
The description of the disclosure is merely exemplary in nature and, thus, variations that do not depart from the gist of the disclosure are intended to be within the scope of the disclosure. Such variations are not to be regarded as a departure from the spirit and scope of the disclosure.
