Biobased granulate for 3D-printing

Reference number
Coordinator Swerea SICOMP AB - Swerea SICOMP AB, Piteå
Funding from Vinnova SEK 499 000
Project duration October 2017 - March 2018
Status Completed
Venture The strategic innovation programme Bioinnovation

Purpose and goal

The project aimed at adept low-value raw materials such as sawdust and forest residues (treetops and branches) so that they became suitable for 3DP after mixing with thermoplastics. The pre-study showed that it was not only possible, but also much cheaper. Two prototypes were shown to industry which ended in a increased consortium. Nefab, large in packaging solutions, and EcoRub, material manufacturer in the future (?) have joined the consortium aiming for new relevant products.

Expected results and effects

This prestudy has shown that it is possible to 3D-print packaging solutions with biobased materials. Knowledge of which parameters can be optimized has provided a good foundation for future projects. The preliminary study also showed that it is a cost saving to use the biomaterials (especially cave) which can also give an increased value. This is important not only to this products with possble products but also important to be able to show to other companies with similar aims to use biomaterials. Two prototypes have been made to show to the industry.

Planned approach and implementation

The project aim was to adapt low-value raw materials such as sawdust and forest residues (treetops and branches) so that they become suitable for mixing in thermoplastics. Various pellets with biomass and plastic were manufactured at Swerea SICOMP. The manufactured pellets were sent to BLB Industries, who evaluate its processability in their unique 3DP. Two prototypes of suitable demonstrators was manufactured, and evaluated, and used for marketing purposes to industry.
