In MIT they do not cease in their innovation and development work to continue advancing in all kinds of technological sectors, we have a proof in how a group of their engineers have managed to develop a novel system capable of substituting petroleum-derived polymers, a material that is normally used in the manufacture of filaments for 3D printing, for a type of vegetable cellulose which offers many more advantages.
As MIT has not hesitated to praise, the use of this type of vegetable cellulose, in the first place, ensures that any object made with this material is renewable and biodegradable, something that is always a point in its favor, although, as they have commented, 3D printing is also achieved more economical and even that the results are more resistant.
MIT engineers promise very interesting features in this new material designed to be used in 3D printing.
As a final advantage, it is especially important that those responsible for this research praise that this material also has antimicrobial properties, something that I personally have to admit that particularly catches my attention.
Leaving all this for a moment 'sideways', tell you that apparently what this group of engineers has used as the base material for the creation of this filament is cellulose acetate. Thanks to this, the material is solidify quickly. In the words of a team spokesperson:
After printing in 3D, we restored the network of hydrogen bonds through a treatment with sodium hydroxide.
