FILAMENTS for 3D printing with customized functionality

Funded Projects



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.

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.

Eco-efficient 3D printing of MultiMaterials with photo- & electrochemical activity for water treatment and the green H2 generation


This project addresses the challenges of rapid prototyping of advanced, environmentally friendly, low-cost and high-efficiency photo- and electrochemical devices as part of the 2030 Agenda for Sustainable Development of the United Nations General Assembly.

COLFEED, in collaboration with the Tailoring through Colloidal Processing group, plans to validate and demonstrate fused filament fabrication (FFF) technology as a prototyping method for these membranes. Moreover, in the case of membranes whose semiconducting particles have electrochemical properties, the direct application will be not only water treatment, but also water splitting photoreaction for the generation of green hydrogen. In this way, the project pursues the optimisation and eco-efficiency in the manufacturing process of membranes with photo and electrochemical activity, trying to tackle not only the current problem of water resource pollution but also the energy crisis, providing a suitable solution for obtaining green hydrogen as an energy vector, as an alternative and/or complementary technology to current hydrogen storage systems.

The industrial doctorate is developed by Pablo Ortega Columbrans, Senior Chemical Engineer under the direction of Dr. Begoña Ferrari from Tailoring through Colloidal Processing group (CSIC-ICV) and Dr. Juan A. Escribano.

NET4MAT – Building knowledge and tools for the sustainable microbial fighting through sensing and responsive polysaccharide-based materials


The worldwide pollution triggered by non-biodegradable plastics requires alternative sustainable/eco-friendly materials for all applications. On the other hand, pathogenic microbial resistance is demanding the development of materials that accurately detect and actuate against pathogenic microorganisms. To exploit an approach that answer both these issues, NET4MAT will bring together experts with complementary skills, building an interdisciplinary and intersectoral consortium between academia/research institutes/industry. NET4MAT network will explore the feasibility of combining microbial sensing lanthanide-glycoclusters and antimicrobial
porphyrinoids with biodegradable and biocompatible polysaccharide-based formulations. With UAveiro focused on synthesizing porphyrinoids and processing 3D structures using the functional polysaccharide-based formulations; CSIC dedicated in extruding bionanocomposites; and DTU focused on electrospinning of NET4MAT materials, it will be created knowledge for developing microbial sensing and responsive biodegradable materials. In a complementary way, UCD will be focused on the synthesis of lanthanide-glycoclusters; GINP, pioneers in using nanocarbohydrates as biocomposites fillers, will improve the materials processability; and HUJI will evaluate the materials antimicrobial activity, biodegradability, and biocompatibility. All together with NOFIMA, SPARTHA, BLAFAR, COLFEED, BEEVC, and COMPONIT will define pathways to scale-up/demonstrate the NET4MAT prototypes, generating skills in different interconnected fields. HISEEDTECH will help NET4MAT partners to create value from knowledge through technology entrepreneurship and open innovation. This is a consortium involving early-stage/senior researchers that by sharing know-how will optimize the best strategies for developing microbial sensing/responsive polysaccharide-based materials, raising up a disruptive breakthrough towards on-demand development antimicrobial biodegradable plastics.
