Python freecad1/31/2024 Open source scientific hardware not only allows a more affordable laboratory equipment, but also contributes to the development of Open Science by facilitating the replication and comparison of the scientific experiments. Inspired by this movement, an engineering research area has emerged to develop open source scientific hardware and laboratory equipment. As a result to this movement many efforts have been made to define open source hardware and set its best practices. This trend has been empowered by open source hardware projects such as the RepRap 3D printers and the Arduino platform, which have made manufacturing and electronic technology accessible and affordable. Over the last years there have been a movement towards creating and sharing Open Source Hardware (OSH). Thus, making it more appropriate to design open source hardware for scientific equipment. The main benefits are being able to export to standard parametric models using Python language with its libraries and the ability to use and integrate the models in its graphical interface. Our findings show that although Python for FreeCAD is more arduous to learn, its advantages counterbalance the initial difficulties. We have created a parametric open source hardware design to compare these tools. In this work we analyze OpenSCAD and compare it with FreeCAD Python scripts. This is an important deficiency because it is key to share the design in the most accessible formats with no information loss. However, OpenSCAD lacks the ability to export to standard parametric formats thus, the parametric dimensional information of the model is lost. OpenSCAD is the most widely used scripting tool for parametric modeling of open source labware. Parametric design using a solid modeling programming language allows customization and provides a source file for the design. In addition, parametric modeling is encouraged in order to facilitate customization for other experiments. Another way, you can also copy the code in Macro editor and create your own custom executable macro with your custom parameters.Open source hardware for scientific equipment needs to provide source files and enough documentation to allow the study, replication and modification of the design. To test the above code, simply copy it and paste in the Python console of FreeCAD and hit enter. In the below Python code mentioned, we tried to parametrically model a sample house. Then by some slight manual interpretations, the code can be refined as per the requirement and reused whenever needed as a separate portable program. Its macro recorder gives you all the commands that you’ve executed so far to build your objects through GUI. In my opinion, so far what I’ve experienced, FreeCAD has got the most friendly ever (and the most powerful too) Python console that even WRITES THE WHOLE CODE FOR YOU. Thanks to my friend Kirandeep Singh for accompanying me for this task. Though, it has been very tough to spare some personal time but still I tried this weekend to spend some time experimenting on FreeCAD’s Python interface and it was a great feeling. Especially, I’ve not posted anything regarding my favourite BIM tool FreeCAD. It has been a year that the blog has been inactive. How are you all doing! Hope you all are great.
