3D printing of FILAMENT-Oss as novel biodegradable and bioabsorbable composites for bone regeneration applications

The printing process of FILAMENT-Oss  is carried out by a Fused Filament Fabrication process (FFF/FDM). As any other Additive Manufacturing technique, the FFF creates a physical 3D object from a digital model (usually a CAD representation) which is sliced in layers at consecutive height levels.  The process requires of a thermoplastic material like polylactic acid (PLA), polycaprolactone (PCL), or acrylonitrile butadiene styrene (ABS), FILAMENT-Oss fulfill this requirement combining a thermoplastic biodegradable matrix and a bioactive ceramic or metallic phase. The method has several steps:

• The procedure starts with the filament drying  at 60ºC before the printing process.
• The CAD representation with extensions STL, OBJ, 3DS, etc. could be obtained by a 3D scanners, design tools software or even internet apps with the digital information of the pieces to be fabricated.
• The computer interface controls the bed position and temperature, the head position and height as well as the nozzle temperature, which depends on the type of filament used. For FILAMENT-Oss a bed temperature of 30-60 ºC,  a printing temperature around 155 – 165 ºC, and a printing speed of 30 – 60 ºC is highly recommended.

FILAMENT-Oss is a  bioactive material supported by a biodegradable polymer matrix for personalized bone regeneration which allows obtaining customized, osseoinductive and readsorbable scaffolds.
