How to check and repair STL files for 3D printing
STL (stereolithography) is a widely used type of file in the world that revolves around 3d printers.
First steps with the OpenSCAD language
This language is based only on some basic concepts. These concepts are quite elementary, but thanks to their combination you can generate any 3d structure.
OpenSCAD: how to create solid 3D objects
is a CAD application (freeware) that serves to create solid 3d objects and is available on all platforms: Windows, Linux and Mac OS X. You can download the latest official website version directly.
T-slot framing: an alternative mechanics with aluminum profiles
T-slot framing is a technology that is widely used for industrial automation, robotics and machine enclosures for the past 30 years. Lately, these framing systems have been increasingly miniaturized and their purchase cost has dropped significantly.
How to make a hexagonal binning using D3 library
This article is linked to the article Hexagonal binning in which this method of aggregation of data is shown starting from a scatterplots representation and then ending with a representation that uses Hexagonal bins.
Hexagonal Binning – a new method of visualization for data analysis
Scatterplots are a simple way to visualize the distribution of data on an XY plane, especially when we want to highlight the presence of clusters or particular trends.
How to make a 2D histogram with D3 library (tutorial)
Before starting with this article, I suggest you read the article Hexagonal binning, in which is explained and shown this method of aggregation. The article compares the scatterplots generated by two different sets of data. It is thus highlighted that for particular sets of data, especially those that are presented as a distribution "sparse" on the XY plane, it can be difficult to detect any clusters or linear trends.
