3D-Cellfilament – step 2

This project is the continuation of the project “BioCell-filament“: Hypothesis testing in BioInnovation step 1. The aim is to replace carbon fiber with nanocellulose as a strength agent in FFF filament for 3D printers.

Today, carbon fiber is often used as a strength agent in plastic- and biocomposite parts in need of good mechanical properties. But carbon fiber is made from non-renewable petrochemicals, instead the project wants to replace carbon fiber with nanocellulose which is an environmentally friendly material of renewable origin.

3D filament is made in an extruder where granular material under heat and high pressure is formed into filaments (thread) and wind up on a coil. However, natural polysaccharides degrade under the conditions prevailing in 3D filament production. Mid Sweden University and Organofuel Sweden AB modify nanocellulose that is mixed with plastics and compounded into biocomposite granulate. Infold AB then extrudes the granulate into 3D filaments. Filaments with different compositions will be analyzed for 3D-printability, chemical- and mechanical properties and up-scaling processes for commercialization.

Budget & time plan

The project’s total budget is 4 MSEK and the project runs during 1,5 years – between May 2022 and December 2023.
