Researchers are doing a sustainable way of printing large objects from cellulose



June 6 (UPI) – Researchers have developed a way to print sustainably large objects with cellulose, a performance previously complicated by a variety of scaling problems and environmental considerations.

Since cellulose is one of the most widely available commercially available compounds, material researchers have tried to find ways to use it in additive production. However, previous methods gave too many toxic byproducts, demanded the use of plastic and cost too much.

Researchers at the Singapore University of Technology and Design could avoid previous problems with a new method of culturing cellulose. Researchers introduced small amounts of chitin, a derivative of glucose, into cellulose fibers. The technique gave what scientists call spongy-like adhesives, or FLAM.

According to researchers, FLAM is completely biodegradable and requires no synthetic plastic to produce. It is also much cheaper to grow than traditional filaments used in 3D printing.

"This reproduction and manufacture with the material composition found in the oomycete wall, namely unmodified cellulose, small amounts of chitosan ̵

1; the second most common organic molecule on earth and low-concentrated acetic acid, is probably one of the most successful technological achievements in bio-inspired materials,

Buoyed by their success, researchers developed a unique additive method to accompany their new cellulose materials.

Researchers reported their breakthrough in the journal Scientific Reports.

[19659002] Researchers are now hoping to collaborate with industrial partners to get their technology from the laboratory to the factory and to develop real applications for FLAM.
