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 size and volumetric output of an extruder was scaling down. Verification was done by mechanical testing, and electron microscopy. The positive result is opening the path to a more accessible composites for both researchers and home producers.
