Purpose: the Purpose of This Grant Is to Improve Additive Manufacturing Processes by Synthesizing Laser Powder Bed Fusion Additive Manufacturing Scan Planning With Targeted Thermally-induced Part Property Development.activities to Be Performed: Activities Will Include Generating New Scan Patterns That Achieve Targeted Thermally-induced Properties. the Applicants Will Then Quantify the Accuracy of the Reduced-order Models for Scan Patterns. Such Models Can Serve as Descriptors of the Part Properties and Are Necessary to Use Custom Patterns for the Generation of Process Plans at the Part Scale. This Activity Focuses on Constructing the Fundamental Correlations Between Design, Material, and Process Primitives. the Project Will Formulate and Validate a Multi-scale Approach for Predicting Path-to-part Scale Thermally-induced Properties in Terms of Reduced-order Models Constructed in the Previous Activity. Finally, the Applicants Will Demonstrate the Ability to Generate Island Scan Patterns That Can Control Thermally-induced Properties.expected Outcomes: in the First Year of the Project, the Research Will Result in New Scan Patterns That Achieve Targeted Thermally-induced Properties and Quantify the Accuracy of the Reduced-order Models for Island Scan Patterns. in the Second Year of the Project, the Research Will Result in a Validated Approach for Predicting Path-to-part Scale Thermally-induced Properties, Designing Island Scan Patterns to Improve Thermally-induced Properties, and Determining the Feasibility of Controlling Solidification Sequences.intended Beneficiaries: U.s. Manufacturers and Solution Providers Will Benefit From an Improved Knowledge Base for Additive Manufacturing. Researchers Will Benefit From Access to Data Sets and New Algorithms for Am Scanning. Targeting Thermal History and Thermally-induced Properties in Tool Path Design Is Critical to Producing High-quality, High-performance Parts. the Proposed Research Is Synergistic With the Ongoing Nist Efforts in Measurement Science for Additive Manufacturing and Data-driven Decision Support for Additive Manufacturing.subrecipient Activities: the Proposal Does Not Include Sub-awards.
