Fabrication of Poly(Glycerol Sebacate)-Poly(ε-Caprolactone) Extrusion-Based Sca...
Reis, D.; Biscaia, S.; Seabra, I. J.; Veloso, A.; Morouço, P.Cartilage related diseases are on the top list concerns of the World Health Organization, being the prevention of articular cartilage degeneration a major health matter for which there are few effective solutions. Using an extrusion-based approach and a polyester elastomer it was aimed to produce 3D structures with controlled architecture and with closer mimicry to cartilage native tissue. The obtained construc...
Traffic Vertical Signposting: Materials Characterization and Structural Numeric...
Franco, M.; Fonseca, R.; Gomes, S.; Biscaia, S.; Brites, F.; Pascoal-Faria, P.; Mateus, A.The existing metallic solutions used for vertical traffic signs are associated with higher costs and environmental issues due to their manufacturing and degradation, when compared with polymeric solutions. Thus, the development of vertical signs considering the injection from polymeric materials in order to overcome problems related with sustainability, maintenance costs, and to achieve higher resistance to cor...
A Novel Biomanufacturing System to Produce Multi-Material Scaffolds for Tissue ...
Viana, T.; Biscaia, S.; Dabrowska, E.; Franco, M.; Carreira, P.; Morouço, P.; Alves, N.This research work aims to validate a new system that enables the fabrication of multimaterial 3D structures using poly(e-caprolactone) and sodium alginate for potential use in Tissue Engineering applications. To produce multi-material scaffolds for Tissue Engineering, accurate techniques are needed to obtain three-dimensional constructs with clinically appropriate size and structural integrity. This paper pres...
The Use of Polypropylene and High-Density Polyethylene on Cork Plastic Composit...
Brites, Fernando; Malça, Cândida; Gaspar, F.; Horta, J. F.; Franco, M. C.; Biscaia, S.; Mateus, A.This work focuses on studying the possibility of 3D printing of composite materials composed by cork and a polymer matrix (CPC). Initially the cork was mixed with two types of polymers (HDPE and PP) in different proportions and later processed using extrusion and injection. The composites were tested to study the physical, chemical and mechanical properties. The material was then tested on a large-scale 3D prin...
Cork Plastic Composite Optimization for 3D Printing Applications
Brites, F.; Malça, C.; Gaspar, F.; Horta, J. F.; Franco, M. C.; Biscaia, S.; Mateus, A.Among natural fillers, cork has been acknowledged as a suitable alternative of other cellular materials that are widely employed in engineering applications due to their low conductivity to heat, noise and vibration, high abrasion resistance and flexibility, high compressibility ratio, among other characteristics [1]. The eco-friendly features of natural fillers based composites make them a very promising and s...
