However, their high cost often makes them inaccessible to hobbyists, early-career researchers, and citizen scientists. With advancements in 3D printing, several do-it-yourself (DIY) thruster designs have emerged, allowing assembly using off-the-shelf components. However, most existing designs provide only printable files. These often lack detailed source information and, more importantly, performance data. This work presents the design, and an updated and expanded evaluation of the open-source OpenThruster project, with a focus on performance variability, fabrication methods, and dynamic modeling. OpenThruster is an open-source, low-cost, and mostly 3D-printed thruster for marine applications. The thruster itself is designed and simulated using open-source software. Performance evaluation is performed using off-the-shelf components and, wherever possible, open-source hardware. To ensure broad accessibility and long-term availability, we selected one of the most widely available drone motors and tested units with identical specifications from various vendors to assess consistency. Experimental validation involved a VESC6 driver board and bollard thrust measurements using a load cell setup in pool water. We also evaluated propellers produced, via three different 3D printing techniques. The thrusters consistently produced an average peak thrust of 18 N at 310 W, with fabrication costs kept under 500 INR (approximately $6). While thrust variation across ten motors from different vendors reached up to 11%, a one-way ANOVA test indicated no statistically significant difference between them. However, propellers made with different printing methods demonstrated significant differences in thrust output.</div></div>","PeriodicalId":37503,"journal":{"name":"HardwareX","volume":"23 ","pages":"Article e00680"},"PeriodicalIF":2.1,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144739504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DIW can be leveraged to print a wide range of multi-material components with unique geometries, which would otherwise be challenging to produce with traditional manufacturing techniques. However, despite their unique capabilities, DIW extruders are costly to purchase and labor intensive to clean, limiting widespread adoption. To address these challenges, an automatic tool changer with tool sharing system was developed to reduce printer capital costs, minimize operator interactions, and increase extruder utilization. Unlike conventional tool changers popular with fused filament fabrication (FFF) printers, which allows a single printer to swap between multiple tools, this novel tool sharing system enables tool sharing and coordination between two adjacent printers. By effectively halving the total number of extruders and associated cleaning operations, DIW capabilities are greatly improved, increasing production, lowering system cost, and minimizing operator involvement.

Traditionally, excised tumor masses are manually sliced for microscopic examination, which is a resource-intensive, time-consuming process, and prone to human error. The proposed work addresses these challenges by developing a cost-effective US gantry system integrated with a deep learning algorithm to automate the tissue slice selection process. This system scans the entire tumor and by integrating a deep learning algorithm predicts the optimal slice to assist its preparation for microscopic analysis. Automating this process reduces the time and resources required while minimizing the risk of human error. Optimal tissue slice reduces sampling associated uncertainty in diagnosis and treatment planning. Thereby determining tumor grade and type, and helping to reduce the treatment risks. The initial development focused on a linear US gantry that moves in one direction to acquire B-mode images. However, this design is limited, as it cannot fully capture the tumor’s structural complexity. In order to overcome this, we developed an angular US gantry that can maneuver along multiple angles, acquiring a broader range of images for comprehensive geometric analysis. The angular gantry demonstrated significant improvement, achieving 98% accuracy in selecting the optimal tissue slice.</div></div>","PeriodicalId":37503,"journal":{"name":"HardwareX","volume":"23 ","pages":"Article e00676"},"PeriodicalIF":2.0,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144685747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
