The current three-dimensional object manufacturing technique relies on the deposition of a pseudoplastic flame retardant material in gel aggregate state. The gel flows through a deposition nozzle because the applied agitation and pressure shears the bonds and induces a breakdown in the material elasticity. The elasticity recovers immediately after leaving the nozzle, and the gel solidifies to maintain its shape and strength. La technique de fabrication d'objets en trois dimensions actuelle selon l'invention comprend le dépôt d'une matière ignifuge pseudoplastique dans un état d'agrégat de gel. Le gel s'écoule à travers une buse de dépôt, car l'agitation et la pression appliquées cisaillent les liaisons et induisent une rupture de l'élasticité du matériau. L'élasticité se rétablit immédiatement après que le gel a quitté la buse, et le gel se solidifie pour conserver sa forme et sa résistance.
