AIMPLAS expands R&D capability with new filament extrusion line for 3D printing
AIMPLAS, the Plastics Technology Center in Spain, has installed a new extrusion line to obtain filaments from a wide range of thermoplastic materials that can be used later to print parts by means of Fused Deposition Modeling (FDM) 3D printing technology.
This filament extrusion line is equipped with a single-screw extruder, controlled cooling bath, haul-off unit and winding system to obtain filaments with thicknesses of 1.75mm and 2.85mm. It can also be modified for other thicknesses.
AIMPLAS said it is now able to process conventional, technical and biodegradable plastics, elastomers and modified materials for R&D projects, such as acrylonitrile butadiene styrene (ABS), polyethylene (PE), polypropylene (PP), thermoplastic polyurethane (TPU), polylactic acid (PLA), among others.
One of the aims is to identify commercial materials that can be used to produce filaments, or to develop customized and optimized materials by means of physical or chemical modification to reach the defined requirements.
It will also allow modifying materials to get functional properties, such as conductivity, solubility, antimicrobial, etc. with applications in different sectors. Assessments will be carried out when the filaments are being used to further optimize the processing parameters for commercial practice.
The filaments extrusion line is complemented by a complete equipment of 3D printers to produce prototypes. AIMPLAS is able to obtain designs by using flexible or rigid filaments of materials with a melt temperature up to 350°C.
