Compounding composites from raw materials with extrusion directly on 3D printer

Rundbäck Martinsson, Oscar LU ; Nordin, Axel LU and Tavčar, Jože LU (2022) 17th International Design Conference, Design 2022 In Proceedings of the Design Society 2(DESIGN2022). p.1431-1440
Abstract
The materials most commonly used in 3D-printers are in a filament form. This is a barrier for users who want to have new types of filaments with different material compositions. A 3D-printer which can extrude and print directly from the raw material was assembled. Compounding with the common additive types; fibres, and metal powders was performed. The key contribution is that scaling down the size and volumetric output of an extruder positively affects the compounding. Verification was done by mechanical testing, and electron microscopy. The positive result is opening the path to a more accessible research field for both researchers and home producers.
