摘要： The invention relates in a first aspect to a process for preparing a 3-dimensional body, in particular a vitreous or ceramic body, which comprises at least the following steps: a) providing an electrostatically stabilized suspension of particles; b) effecting a local destabilization of the suspension of particles by means of a localized electrical discharge between a charge injector and the suspension at a predetermined position and causing an aggregation and precipitation of the particles at said position; c) repeating step b) at different positions and causing the formation of larger aggregates until a final aggregate of particles representing a (porous) 3-dimensional body (green body) having predetermined dimensions has been formed; wherein the charge injector includes i) at least one discharge electrode which does not contact said suspension of particles or ii) a source of charged particles. A second aspect of the invention relates to a device, in particular for performing the above process, comprising at least the following components: - a vessel for receiving an electrostatically stabilized suspension of particles, - a charge injector, in particular including one or more electrodes or a source of high-energy charged particles, - means for moving the electrode and/or the vessel in the x, y and z directions, - a counter electrode arranged in the vessel for a contact with the suspension of particles, - one or more sensors for determining geometrical and physical parameters within said vessel. In one preferred embodiment, said device further comprises a means for directing a beam of gas-ionizing radiation, in particular a laser beam, to a predetermined position within the vessel.

摘要： Provided herein are biocompatible scaffolds and methods of preparing such bioscaffolds. The methods provide a superior high surface area, interconnected nanomacroporous bioactive glass scaffold, by combining a sol-gel process and polymer sponge replication methods. The formation of a uniformly nanoporous and interconnected macroporous bioscaffold is demonstrated using a starting material comprising a 70 mol% SiO2-30 mol% CaO glass composition as an example. The bioscaffold includes a series of open, interconnected macropores with size from 300 to 600 µm, as desired for tissue ingrowth and vascularization. At the same time, coexisting nanopores provide high-specific surface area (>150 m2/g), which is needed for enhancing the structure's degradation rate. These bioscaffolds hold promise for applications in hard tissue engineering.
