FILAMENTS for 3D printing with customized functionality

The Process

Our technology is based on a colloidal dispersion method which results in the production of highly homogeneous printable feedstocks with different inorganic phases. Thanks to our technology, we can customize the composition of our products varying both the inorganic load and its volume ratio with the thermoplastic phase

Printable in FDM equipment

Easy to print from digital designs

From small batches for strategic % high added-value materials

Customizable compositions

Funded Projects

FILAMENT-OSS HA

 

COLFEED4Print, an innovative company based on the knowledge generated at the Institute of Ceramics and Glass (ICV) of the CSIC, has generated a solution for the elevation of the maxillofacial sinus on which dental implants are placed.

 

FOss-HA is a resorbable and osseointegrated biomaterial in filament format for the in situ 3D printing of customised osteoinductive structures. The most significant features of our materials are their mechanical consistency and their ability to be customised to the patient. With our innovative colloidal wet-mixing process, a high degree of dispersion and homogenisation of the osteoinductive phase within the resorbable polymer is achieved, which is not possible with conventional processes.

 

This project, funded by the Centre for the Development of Industrial Technology (CDTI), is dedicated to the implementation of an exclusive production line for FOss-HA, with the aim of achieving the necessary certifications that will allow it to be used for the printing of 3D parts for maxillofacial bone regeneration. For this, it will also be necessary to verify and validate the biocompatible, biodegradable, osteoconductive and osseointegrative properties of the filaments both in vitro and in vivo.

VIVALDI: “CERAMIC AND METALLIC WASTE VALORIZATION THROUGH DUST GENERATION FOR ADDITIVE MANUFACTURING AND OTHER HIGH-VALUE-ADDED APPLICATIONS”

 

The VIVALDI project is a collaborative business initiative, funded by the Centre for the Development of Industrial Technology (CDTI), whose general objective is to carry out industrial research into the recovery of composite, metallic and ceramic material waste by generating recycled powders for incorporation into the feedstocks of additive manufacturing processes, such as Fused Feedstock Manufacturing (FFM) and Selective Laser Melting (SLM) and Laser Cladding (LC). 

 

The VIVALDI project will investigate how to obtain recycled powder from high-tech materials, such as titanium (Ti), aluminium (Al), tungsten carbide (WC) and carbon fibre (CF), using different routes and/or processes, such as centrifugal atomisation or microwave plasmonisation and thermochemical processes for the prior recycling of the composites. The revalorised powder will be incorporated into the raw material in additive manufacturing technologies, such as FFM or SLM, benefiting from the synergy of the project by simultaneously researching in manufacturing equipment engineering (FFM, SLM) and valorisation/granulation processes, in order to offer feedstock and equipment currently not available on the market.

 

In the VIVALDI project, recycled particles will be combined with commercial particles when generating feedstock for additive manufacturing in order to maintain the properties of the final parts. The project has set an ambitious target of generating print feedstock with at least 15% recycled material by volume. The project will also investigate the 3D printing process, as well as the subsequent debinding and sintering processes of these new materials.
