However, during the molding process of extrusion-based additive manufacturing, the influence of healing temperature, interlayer pressure, and insufficient healing time leads to inadequate healing behavior between deposition paths, making it challenging to maintain mechanical strength consistency in the deposition direction with other directions. Considering the interlayer healing theory of polymers, this study proposes a 3D printing strategy based on material extrusion, achieving enhanced interlayer mechanical properties through topologically optimized nozzle structures. Firstly, based on the rheological behavior of consumables at the nozzle of the fused filament fabrication (FFF) extruder, a molten fluid deposition model is established, and the nozzle cross-sectional shapes for different target extruded filament shapes are obtained through inverse extrusion prediction techniques. On this basis, combined with the interlayer healing strength theory of FFF extrusion molding, the relationship between extruded filament geometry, intimate contact, and contact pressure is analyzed to achieve the goal of improving the interlayer tensile strength of molded parts. A highly compatible, real-time monitorable 3D printing platform was established, and standard tensile specimens of different extruded filaments were prepared and their tensile properties measured to validate the correctness of the multi-path deposition model. Results showed that compared to traditional nozzles, the interlayer tensile strength of parts manufactured using square nozzles increased by approximately 37.8 %.

This study employs Electron Beam Drip Melting (EBDM) technology to fabricate GH4151 superalloy casting with uniform microstructures. The results indicate a significant reduction in the content of gaseous impurity elements in the casting, with an O content of only 2.0 ± 0.1 ppmw. The microstructure of the casting is dense, with grains growing axially, and the secondary dendrite arm spacing (<em>λ</em>_<em>2</em>) at the center of the casting is approximately 50 μm. The sizes of low-melting point phases between dendrites are small, with a total area fraction of &lt;0.4 %, and the number and size of these phases significantly decrease as the height of the casting decreases. The microsegregation coefficients (<em>k</em>) for three typical easily segregated elements are <em>k</em>_W &lt; 1.45, <em>k</em>_Ti &gt; 0.70, and <em>k</em>_Nb &gt; 0.45, respectively. The γ′ phases within the casting are all square-shaped, with sizes of approximately 300 nm for dendrite cores and 400 nm for the inter dendritic γ′ phases. After homogenization treatment, the primary γ′ phase size reaches 550 nm. Calculations show that during the EBDM preparation of the casting, the temperature gradients (<em>G</em>) at the center and at R/2 are 7.2 K/mm and 15.1 K/mm, respectively. Compared to other melting methods, the ability to replenish the mushy zone is enhanced, and the sensitivity to cracking is reduced. The EBDM-GH4151 casting exhibit higher levels of both yield strength and elongation compared to those produced by other melting methods. This study demonstrates that the EBDM process can refine the as-cast microstructure of high-alloyed superalloys, providing castings with a higher uniformity for subsequent heat treatment and thermal processing.</div></div>","PeriodicalId":16148,"journal":{"name":"Journal of Manufacturing Processes","volume":"141 ","pages":"Pages 1048-1059"},"PeriodicalIF":6.1,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143628326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But existing solutions either require explicit knowledge of externality variations which is typically unavailable or they render the part unusable due to infeasibly slow defect mitigation. This work addresses this issue by establishing a novel Conditional Reinforcement Learning (ConRL) approach for rapid and real-time data-driven defect mitigation based on an implicit consideration of externality variations. Validation within a smart manufacturing pipeline on a Fused Filament Fabrication testbed reveals the unprecedented ability to mitigate defects at 10× greater speed via a single control action and within the same printed line.
