  • Publication number: 20220363011
    Abstract: Printer control data is generated which includes a three dimensional model for a protective structure to be built around a printed object by a three-dimensional printing apparatus, which protective structure is configured to compensate for the distorting effects of uneven shrinkage during cooling. The three dimensional model for the protective structure comprises a plurality of side panels and at least one extensible member interconnecting two or more of the side panels, which extensible member is configured to be extensible in response to shrinkage of the plurality of side panels during cooling. A method and apparatus is disclosed which obtains object model data defining an object to be built by a three-dimensional printing apparatus and automatically generates a three dimensional model for a suitable protective structure that has extensibility as an integral feature of the design to compensate for uneven shrinkage.
