摘要： This invention relates to processes and systems of rapid prototyping and production. Its features includes flexible material deposition along tangential directions of surfaces of a part to be made, thereby eliminating stair-shape surface due to uniform horizontal layer deposition, increasing width of material deposition to increase build up rate, applying the principles of traditional forming/joining processes, such as casting, fusion welding, plastic extrusion and injection molding in the fabrication process so that various industrial materials can be processed, applying comparatively low cost heating sources, such as induction heating and arc-heating. Additional features include varying width and size of material deposition in accordance with geometry to be formed and applying a differential molding means for improved shape formation and surface finishing.

摘要： Some variations provide a method of making an additively manufactured single-crystal metallic component, comprising: providing a feedstock comprising a first metal or metal alloy; providing a build plate comprising a single crystal of a second metal or metal alloy; exposing the feedstock to an energy source for melting the feedstock, generating a melt layer on the build plate; and solidifying the melt layer, generating a solid layer (on the build plate) of a metal component. The solid layer is also a single crystal of the first metal or metal alloy. The method may be repeated many times to build the part. Some variations provide a single-crystal metallic component comprising a plurality of solid layers in an additive-manufacturing build direction, wherein the plurality of solid layers forms a single crystal of a metal or metal alloy with a continuous crystallographic texture. The crystal orientation may vary along the additive-manufacturing build direction.

摘要： A method for manufacturing an additively-manufactured object, includes: an additively-manufacturing step of building a layered body by depositing a weld bead obtained by melting and solidifying a filler metal, the layered body having an opening along a forming direction of the weld bead and an internal space surrounded by the weld bead; and a closing step of forming a closing wall portion connecting an edge portion of the opening with the weld bead for closing. In the additively-manufacturing step, the opening is formed with a width dimension larger than a bead width of the weld bead, and in the closing step, the closing wall portion having a width dimension larger than the bead width is formed by the weld bead to close the opening.

摘要： An additively manufacturing method includes: measuring a filler metal feed speed at which the filler metal is fed to the welding torch during the formation of the weld bead; acquiring a reference welding speed that is a moving speed of the welding torch corresponding to the measured filler metal feed speed; measuring a height of the formed weld bead; acquiring a welding speed correction value with which the height of the weld bead to be formed is adjusted based on a difference between the measured height of the weld bead and a height of a tip of the filler metal that protrudes from the tip of the welding torch; correcting the reference welding speed with the welding speed correction value and determining a welding speed at which the weld bead is formed; and forming the weld bead at the determined welding speed.

摘要： The present disclosure provides a wire and arc additive manufacturing (WAAM) method for a magnesium alloy. The method includes the following steps: step 1: performing a WAAM process assisted by cooling and rolling; step 2: milling side and top surfaces of an additive part; step 3: performing, by friction stir processing (FSP) equipment, an FSP process on the additive part, and applying cooling and rolling to a side wall of the additive part through a cooling and rolling device during the FSP process; step 4: finish-milling the top surface of the additive part for a WAAM process in the next step; and step 5: repeating the above steps cyclically until final forming of the part is finished. The present disclosure completely breaks dendritic structures and refines grains in the WAAM process of the magnesium alloy, thereby effectively repairing defects such as pores and cracks.

摘要： A method for manufacturing an additively-manufactured object in which deposition is performed by melting and solidifying a metal depending on three-dimensional shape data of a target shape, includes: acquiring the three-dimensional shape data; creating a deposition plan in which a formation track and a heating condition of the metal are determined; determining a difference between a shape of the additively-manufactured object that thermally contracts by cooling after deposition and a shape of the three-dimensional shape data by an operation; modifying the deposition plan until the difference falls within a predetermined allowable range; and additively manufacturing the additively-manufactured object based on the deposition plan in which the difference falls within the allowable range.

摘要： A tool bit with a surface layer metallurgically bonded on a substrate layer using electrospark deposition (ESD) that allows the tool bit to reduce camout and engage a fastener head for one-handed starting and removal. The surface layer has a rougher finish, compared to conventional tool bits, and therefore better grips engagement surfaces of a mating recess of the fastener during use. The reduction of camout provides greater durability to the tool bit and resists erosion and wear of the engagement surfaces of the fastener.
