Abstract: A method for three dimensional printing of a large sized object is provided. The method includes creating a three dimensional model associated with the object to be printed and analyzing a geometry of the three dimensional model. The method also includes placing seams on a deflated support member to form pathways on the support member such that the pathways are formed based on the analyzed geometry of the three dimensional model. The method further includes introducing a pressurized fluid into the pathways and further inflating the support member to conform to the analyzed geometry. The inflation is done to a predetermined pressurized geometry associated with the support member. The method also includes supporting the three dimensional printing of the object by the inflated support member. The inflated support member is configured to prevent at least one of an overhanging or a collapse of materials of the object prior to solidification.

Abstract: A method for determining a welding sequence including a plurality of welding operations is disclosed. The method includes steps of determining a population of welding sequences based on a set of user-generated constraints, and simulating welding for at least one welding sequence in the population of welding sequences to obtain a multi-objective dependent distortion model of the at least one welding sequence. The method further includes steps of comparing a merit value of the multi-objective dependent distortion model for the at least one welding sequence with one or more predetermined criteria, and outputting a set of welding sequences as potential welding sequences based on the comparison between the merit value and the multi-objective dependent distortion model.
