Abstract: A three-dimensional (3D) metal object manufacturing apparatus is operated to compensate for surface deviations of overhanging features differently than for non-overhanging features. The compensation technique used for the overhanging features depends on whether an edge of the overhanging feature being formed in a next layer has curved or sharp corners.

Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a liquid silicate application system to apply liquid silicate to a surface of a build platform prior to manufacture of a metal object. The liquid silicate layer is permitted to air dry and then the platform is heated to its operational temperature range for formation of a metal object with melted metal drops ejected by the apparatus. The liquid silicate layer forms a glassy, brittle layer on which the metal object is formed. This brittle layer is removed relatively easily with the object after the object is manufactured and the build platform is permitted to cool. The silicate layer improves the wetting of the surfaces of build platforms made with non-wetting materials, such as oxidized steel, while also preventing metal-to-metal welds with wetting materials, such as tungsten or nickel.

Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a silicate slurry application system to build support structure layers with fused particulate suspended in the silicate slurry or to apply a layer of the silicate slurry to a metal support structure prior to manufacture of a metal object feature that is supported by either type of support structure. The fused particulate of a silicate support structure or a layer applied to a surface of a metal support structure forms a glassy, brittle layer on which the metal object feature is formed. This glassy, brittle structure is removed relatively easily from the object after the object is manufactured.

Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a borate solution application system to either build support structures with a borate solution containing silica particles or to apply such a borate solution to a surface of a metal support structure prior to manufacture of a metal object feature that is supported by the support structure. The silica particles in the borate solution structure form a glassy, brittle structure on which the metal object feature is formed. This glassy, brittle structure is removed relatively easily from the object after the object is manufactured.

Abstract: A three-dimensional (3D) metal object manufacturing apparatus is equipped with a borate solution application system to apply a borate solution to a build platform surface prior to manufacture of a metal object. The borate solution is permitted to air dry before the platform is heated to its operational temperature range for formation of a metal object on the platform. The evaporation of the solvent from the borate solution causes the borate salt to form a glassy, brittle anhydrous borate layer on which the metal object is formed. This brittle layer is removed relatively easily with the object after the object is manufactured and the build platform is permitted to cool. The borate layer improves the wetting of the surfaces of build platforms made with non-wetting materials, such as oxidized steel, while also preventing metal-to-metal welds with wetting materials, such as tungsten or nickel.
