However, the nonuniform distribution of mechanical properties in large-sized HPDC products adds complexity to part property evaluation. Therefore, a methodology for property prediction must be developed. Material characterization, simulation technologies, and artificial intelligence (AI) algorithms were employed. Firstly, an image recognition technique was employed to construct a temperature-microstructure characteristic model for a typical HPDC Al7Si0.2Mg alloy. Moreover, a porosity/microstructure-mechanical property model was established using a machine learning method based on the finite element method and representative volume element model results. Additionally, the computational results of the casting simulation software were mapped with the porosity/microstructure-mechanical property model, allowing accurate prediction of the property distribution of the HPDC Al-Si alloy. The AI-enabled property distribution model developed in this study is expected to serve as a foundation for intelligent HPDC part design platforms in the automotive industry.</p></div>","PeriodicalId":7342,"journal":{"name":"Advances in Manufacturing","volume":"12 3","pages":"591 - 602"},"PeriodicalIF":4.2,"publicationDate":"2024-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140154470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the advancement of four-dimensional (4D) printing, the programming of sequential motions of smart structures is endowed with more design and manufacturing possibilities. In this research, we present a method for physically programming the timescale of shape change in 4D-printed bilayer actuators to enable the sequential motion and self-assembly of smart structures. The effects of the geometric and printing parameters on the time-dependent behavior of 4D-printed bilayer actuators are investigated. The results show that the thickness of the active layer directly affects the timescale of motion, and increasing the thickness leads to faster motion until the thickness ratio is close to 4:6. Similarly, a higher printing speed results in faster motion. Conversely, a higher printing temperature and a greater layer height result in a slower shape change. The effects of the length-width ratio, line width, and filling ratio on the timescale of motion are not as straightforward. Finally, we demonstrate several smart structures that exhibit sequential motion, including a labyrinth-like self-folding structure that is choreographed to achieve multi-step self-shaping and a flower-shaped structure where each part completes its movement sequentially to avoid collisions. The presented method extends the programmability and functional capabilities of 4D printing.</p></div>","PeriodicalId":7342,"journal":{"name":"Advances in Manufacturing","volume":"12 4","pages":"726 - 741"},"PeriodicalIF":4.2,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140148389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the industrial application of nano-enhanced biolubricants (NEBL) in grinding wheels and workpiece interfaces as a cooling and lubricating medium still faces serious challenges, which are attributed to the knowledge gap in the current mapping between the properties and grindability of NEBL. This paper presents a comprehensive literature review of research developments in NEBL grinding, highlighting the key challenges, and clarifies the application of blind spots. Firstly, the physicochemical properties of the NEBL are elaborated from the perspective of the base fluid and nanoadditive phase. Secondly, the excellent grinding performance of the NEBL is clarified by its distinctive film formation, heat transfer, and multiple-field mobilization capacity. Nanoparticles with high thermal conductivity and excellent extreme-pressure film-forming properties significantly improved the high-temperature and extreme-friction conditions in the grinding zone. Furthermore, the sustainability of applying small amounts of NEBL to grinding is systematically evaluated, providing valuable insights for the industry.

Electroless plating is a potential method for metalizing plastic 3D-printed parts; however, conventional approaches rely on pre-surface activation and catalyzation with expensive metal catalysts and hazardous acids. To address these issues, the current study represents a novel eco-friendly and low-cost approach for direct metallization of non-conductive 3D-printed parts, without using hazardous, toxic, and expensive conventional pre-treatments. Using the developed methodology, we electrolessly copper plated polymer-copper infused 3D-printed part as well as plastic components for the first time, directly. We initiated and implemented the idea of exposing the copper particles embedded in the polymer to the surface of copper-polymer parts by applying a sustainable mechanical or chemical method to make the surface conductive and ready for direct plating. A formaldehyde-free (green) electroless copper solution was developed in-house in addition to skipping conventional etching pre-treatment using harmful chemicals, making this a real step forward in the sustainable metallization of 3D-printed parts. In this study, the mechanical properties of copper-polylactic acid (PLA) 3D-printed parts revealed a 65% reduction in tensile strength and 63% increase in tensile modulus, compared to virgin PLA. Furthermore, the morphological characterization of the copper coated 3D-printed parts showed a homogeneous copper coating on the surface after direct electroless plating, with a plating rate of 7.5 μm/h. Allowing complex and functional devices printed in this manner to be quickly metalized without modification using toxic and costly solutions is a significant advancement in lowering the cost and manufacturing complexity of 3D-printed parts, increasing efficiencies, and lowering weight, and thus is a game changer in the technology’s adoption.</p></div>","PeriodicalId":7342,"journal":{"name":"Advances in Manufacturing","volume":"12 4","pages":"784 - 797"},"PeriodicalIF":4.2,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140047051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The demoulding stage of the micro injection moulding can adversely affect the surface integrity due to friction, adhesion and thermal stresses between the metallic mould and polymeric replicated part. In the present work, we propose the use of precision electropolishing (EP) as a shaping and polishing process to control the draft angle and fillet radius of micro features in order to ease demoulding. Typical defects that occur in replicated polymer parts include cracks, burrs and distorted features. A nickel mould having multiple linear ridges and star shape patterns was designed for the present investigation to have characteristic dimensions ranging from 10 μm to 150 μm and with various aspect ratios to study the effect of electropolishing on modifying the shape of micro features and surface morphology. A transient 2D computational analysis has been conducted to anticipate the effect of shaping on the Ni mould after electrochemical polishing with non-uniform material removal rates, based on the distribution of current density. The experimental results indicate that after shaping using EP, the draft angle of star-patterns and linear patterns can be effectively increased by approximately <span>(3.6^circ)</span>, while the fillet radius increases by up to 5.0 μm. By controlling the electropolishing process, the surface roughness can be maintained under 50 nm.

However, most users cannot test the strength of printed parts, and little information is available about the mechanical properties of printed high-impact polystyrene (HIPS) parts using desktop 3D printers. In this study, the user-adjustable parameters of desktop 3D printers, such as crisscross raster orientation, layer thickness, and infill density, were tested. The experimental plans were designed using the Box-Behnken method, and tensile, 3-point bending, and compression tests were carried out to determine the mechanical responses of the printed HIPS. The prediction models of the process parameters were regressed to produce the optimal combination of process parameters. The experimental results showcase that the crisscross raster orientation has significant effects on the flexural and compression strengths, but not on the tensile strength. With an increase in the layer thickness, the tensile, flexural, and compression strengths first decreased and then increased, reaching their minimum values at approximately 0.16 mm layer thickness. In addition, they all increased with an increase of infill density. It was demonstrated that when the raster orientation, layer thickness, and infill density were 13.08°/–76.92°, 0.09 mm, and 80%, respectively, the comprehensive mechanical properties of the printed HIPS were optimal.

Thus, the upper limit of the weld window is governed by the evolution of dynamic stresses and temperatures at the weld interface. Current formulations for the upper limit of the collision weld window assume that both the flyer and target are made of the same material and approximate stress propagation velocities using the acoustic velocity or the shear wave velocity of the weld material. However, collision welding fundamentally depends on the impacts that generate shockwaves in weld members, which can dominate the stress propagation velocities in thin weld sections. Therefore, this study proposes an alternative weld window upper limit that approximates stress propagation using shock velocities calculated from modified 1-D Rankine-Hugoniot relations. The shock upper limit is validated against the experimental and simulation data in the collision welding literature, and offers a design tool to rapidly predict more accurate optimal collision weld process limits for similar and dissimilar weld couples compared to existing models without the cost or complexity of high-fidelity simulations. </p></div>","PeriodicalId":7342,"journal":{"name":"Advances in Manufacturing","volume":"12 2","pages":"365 - 378"},"PeriodicalIF":4.2,"publicationDate":"2024-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139584282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
