A powder bed (32) is built up by repeated deposition of a slurry that contains powder. Layers are made by depositing a liquid dispersion of the desired powdered material, which then slip-casts into the forming powder bed to make a new layer (34). The slurry may be deposited in any suitable manner, such as by raster or vector scanning, or by a plurality of simultaneous jets that coalesce before the liquid slip-casts into the bed, or by individual drops, the deposits of which are individually controlled, thereby generating a regular surface for each layer.
L'invention concerne un lit (32) de poudre formé par dépôt répété d'une boue contenant de la poudre. Des couches sont constituées par dépôt d'une dispersion liquide contenant la matière poudreuse voulue, qui est ensuite coulée en barbotine dans le lit de poudre de formage pour produire une nouvelle couche (34). La boue peut être déposée par tout moyen approprié, tel un balayage de trame ou vectoriel, par plusieurs jets simultanés qui coalescent avant que le liquide ne soit coulé en barbotine dans le lit, ou par des gouttes isolées dont le dépôt est commandé individuellement, ce qui permet de produire une surface régulière pour chaque couche.
