Yes, it is a rare title, but IC3D is the new plastic filament that you can check as a consumable for your 3D printer. An open source plastic filament, as the title says, since the companies that manufacture 3D printers sell only proprietary hardware and original materials such as plastic consumables (the equivalent of the vat or toner cartridges of conventional printers for those of you who are not familiar with 3D printing).
In addition, the plastic necessary to create the three-dimensional printed figures is sold at quite high prices, since manufacturers inflate prices and they take advantage of users in this regard. It is an ABS multimeter like the one found in LEGO blocks that can reach up to hundreds of € / kg. And many companies threaten their customers that they will lose the warranty if they use other compatible or cheaper filaments. Fortunately, with the launch of free printers like the RepRap 3D came a reduction in costs, but it is still insufficient for many pockets ...
But the problem of the filaments remains, since they were all materials created in laboratories by companies and with proprietary rights to the "recipe" for plastic. They patented these and could play with the prices as they pleased. But now efforts have been made to create a detailed list, in addition to software such as OpenSCAD, and FreeCAD, and the recycling possibilities (see recyclebot) of polymers to put them at the service of 3D printer users. And now it comes IC3D with your IC3D ABS OSHWA (Open Source HardWare Association) certified. They also promise to improve the consistency, precision, diversity and quality of the material for the industry.
