Compositions and processes for producing additively manufactured and/or thermally converted composite articles in 3D form are disclosed. The final products are optionally (i) produced by closed-loop recycling processes, (ii) achieved by electroconversion processes, (ii)i glazed prior to thermal conversion, and/or (iv) exposed to energy efficient conversion techniques, such as microwave heating and/or combustion synthesis, to promote and/or preserve nanograin or micrograin morphology. L'invention concerne des compositions et des procédés de production d'articles composites fabriqués de manière additive et/ou convertis thermiquement sous forme 3D. Les produits finaux sont éventuellement (i) produits selon des procédés de recyclage en boucle fermée, (ii) obtenus au moyen de procédés d'électroconversion, (iii) émaillés avant conversion thermique, et/ou (iv) exposés à des techniques de conversion efficaces en énergie, telles qu'une synthèse par combustion et/ou par chauffage par micro-ondes, pour favoriser et/ou préserver la morphologie des nanograins ou des micrograins.
