Zusammenfassung:	Manufacture of three-dimensional scaffolds with bioactive mesoporous glasses by rapid prototyping. A macroporous scaffold (200 - 1,000 microns) is manufactured from a mesoporous bioactive glass of previously known porosity (2-50 nm) that is mixed with the necessary components to obtain a paste of the necessary consistency so that it can be injected by a rapid prototyping robot. The subsequent elimination of these coadjuvants by calcination leads to the obtaining of a pure and manageable ceramic material. The method allows to conserve this initial porosity and obtain a scaffold of three-dimensional porosity designed and interconnected. In addition, the scaffolding does not present polymers in its composition, thus avoiding the possible toxicity problems that may result. The composition and structure of the manufactured scaffolds make them optimal for use in tissue engineering for bone regeneration and as a release system for bone regeneration. Active principles.
