In L-PBF an inert gas is used to protect the melt pool from contamination by reactive elements in the build chamber and to carry away by-products generated by the laser-powder interaction, including soot, condensate, etc. Spatial variations or other undesirable characteristics (e.g., turbulence, dead zones, etc.) in the gas flow distribution could enable build defects to develop that cause spatial variability in metal quality and microstructure, as well as variability in the mechanical properties. This investigation analyzed the gas flow in a full-scale model of the build chamber for a commercial system utilizing high-fidelity Particle Image Velocimetry (PIV). Planar mode views showed that the gas flow within the build chamber is not uniform and that the flow distribution across the build plate undergoes a reduction in velocity laterally of nearly 50 %; the reduction in flow downstream from the gas inlet to the exit reaches nearly 70 %. Serial views involving multiple planes of evaluation revealed regions of stagnation as well as recirculation zones that could entrain soot and metal vapor condensate. Lastly, a modified Y-Duct design is conceived and shown through analysis performed using PIV to substantially improve the flow field distribution across the build plate. Details of the flow fields, locations of concern, and benefits of the PIV approach to assess and inform improvements in the gas flow distribution are discussed. These findings can lead to improvements in quality realized by part placement and distinguish opportunities for further tuning of the gas flow overall.</div></div>","PeriodicalId":7172,"journal":{"name":"Additive manufacturing","volume":"106 ","pages":"Article 104810"},"PeriodicalIF":10.3,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949083","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}

In this context, the plume refers to the bright melt-pool-scale metal vapor and condensate. A U-Net convolutional neural network (CNN) was trained to segment the plume from experimental images. A comparison of the plume generated from different metals shows that Ti-6Al-4V has a significantly brighter and larger plume than Inconel 718 and 316L SS, which may be attributed to increased emission from the melt pool, increased scattering of the emission from the melt pool, or elemental emission lines. The effect of powder was studied for both Ti-6Al-4V and 316L SS and shows a reduction in the size and brightness of the plume in most overhead images, suggesting that the plume visibility and/or the plume itself is suppressed by the powder and spatter. Process mapping the plume in power and scanning velocity space shows that the plume transitions from ejecting toward the rear of the melt pool in the transitional regime to ejecting directly above the melt pool in both the severe keyholing and conduction-dominated regimes, consistent with the vapor depression geometry under the laser. The temporal variability of the plume increases with increasing power-to-velocity ratio, which is attributed to melt pool and vapor depression instability, but can also be large at very low power-to-velocity ratios. This experimental study aims to increase our understanding of the plume’s behavior at the melt pool scale in LPBF and can be used to validate multi-physics models of the plume and inform parameter selection for both minimal melt-pool-scale laser-plume interaction and avoiding plume interference in melt pool imaging.</div></div>","PeriodicalId":7172,"journal":{"name":"Additive manufacturing","volume":"106 ","pages":"Article 104797"},"PeriodicalIF":10.3,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949084","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}

This review addresses this gap by cataloguing key performance metrics from the literature, including input/output range, sensitivity, mechanical and electrical properties, and the specific 3D printing processes used, to enable meaningful comparison.

Additionally, underreported characteristics such as hysteresis, drift, and long-term stability are considered to provide a more complete assessment of sensor performance. Beyond quantitative comparison, this review introduces a framework for categorizing sensors based not only on electrical output type (e.g., resistive, capacitive) but also on the underlying sensing basis, distinguishing whether the response arises from intrinsic material properties (e.g., quantum tunneling, percolation) or from structure-induced mechanisms (e.g., constriction resistance).

This work introduces a sequential-crosslinking facilitated printing strategy that leverages rapid ionic crosslinking triggered by in-air droplet collision to retain structure during printing and entrap the target biomaterial, which is further crosslinked after printing. This versatile approach enables the effective printing of both photocrosslinkable and non-photocrosslinkable soft biomaterials that are challenging to be printed with normal DDC inkjet 3D printing. The dynamics of DDC process with crosslinking is revealed and two distinct DDC modes are identified, namely, coalescence and stretching separation; dimensionless phase diagrams and semi-empirical transition boundaries of DDC modes are developed to improve the stability of printing process and guide the optimization of printing parameters. On this basis, lines exhibiting a minimum width of 122 μm and delicate motifs containing intricate microfeatures are printed.
