Abstract
A method of 3D printing a part with an overhanging portion requiring support during printing is provided. The method includes moving a dynamically adjustable support member to support the overhanging portion during printing of the part. The dynamically adjustable support member may be moved from a retracted position to a support position after a first portion of the part is printed and the overhanging portion may be supported by the dynamically adjustable support member in the support position. The part may be printed in a 3D printing chamber with a base and at least one wall. The base may have a first dynamically adjustable support member and the at least one wall may have a second dynamically adjustable support member. A first overhanging portion and a second overhanging portion of the part may be printed over the first dynamically adjustable support member the second dynamically adjustable support member, respectively.
