  • Paste filled with metal powder and metal products obtained with same
    Patent number: 6974656
    Abstract: The present invention relates to a paste composition, including a bonding agent charged with a metallic powder, to be used in a prototyping procedure, a procedure for obtaining metallic products from said composition, and a metallic product obtained from said procedure. The composition is characterized by the fact that it includes: a bonding agent comprised of at least one photopolymerizable resin, with a viscosity of less than 4000 mPa.s, measured at 25° C., a photoinitiator, in a concentration greater than 0.2% by mass with respect to the mass of the resin, and a metallic powder in a volumetric concentration greater than 40% with respect to the composition, with said composition having a minimum reactivity on the order of 5 mm3/s per watt of lighting power.

  • Metallic filled pastes
    Patent number: 6630009
    Abstract: A paste composition, including a binding agent charged with metallic powder, to be used in a solid freeform fabrication procedure, comprising: a) a solidifiable binding agent comprised of at least one polymerizable resin, with a viscosity of less than 4000 mPa.s, measured at 25° C.; b) at least one initiator, in a concentration greater than about 0.1% by mass with respect to the mass of the resin; and c) a mixture of at least two metallic powders, said mixture having a volumetric concentration greater than 40% with respect to the composition, wherein said mixture of metal powders is either i) a bimodal or trimodal mixture in nature, or ii) is a majority of stainless steel with an amount of NiB or NiP and combinations thereof effective to lower the sintering temperature.
