摘要： Disclosed is a method and apparatus for making a prototype injection molded part. An extruder of the type used for fused deposition modeling injects production thermoplastic material into a heated nonconductive plastic mold tool slowly at low pressure in an isothermic process. The mold tool may be built from a CAD drawing by fused deposition modeling or another rapid prototyping technique. Using the present invention, an injection molded prototype part can be made from a digital representation of the part within 24 hours by an engineer in an office environment.

摘要： Disclosed is a method for making a prototype plastic injection molded part from a mold tool (10) built by fused deposition modeling. The mold tool (10) is built by depositing roads of a molten thermoplastic resin in layers in a predetermined pattern defined by computer file data representing the inverse of the desired prototype molded part, and is used in an injection molding machine without the addition of any reinforcement fill material or layers to create the prototype part. The disclosed method provides prototype plastic injection molded parts within a twenty-four hour time period.

摘要： Data corresponding to a desired shape of a prototype is transmitted to a rapid prototyping system. The system calculates a sequence for extruding flowable material that thermally solidifies so as to create the desired geometric shape. A heated flowable modeling material is then sequentially extruded at its deposition temperature into a build environment that maintains the volume in the vicinity of the newly deposited material in a deposition temperature window between the material's solidification temperature and its creep temperature. Subsequently the newly extruded material is gradually cooled below its solidification temperature, while maintaining temperature gradients in the geometric shape below a maximum value set by the desired part's geometric accuracy.

摘要： A digital manufacturing system for producing first and second objects comprises a platen, a gantry, a pantograph extrusion head system and first and second sets of extruders. The platen defines a workspace upon which the objects are produced. The gantry defines a headspace displaced from the workspace. The extrusion head system is mounted to the gantry for movement in the headspace. The sets of extruders are connected to the extrusion head system and are configured to deposit extrusion material on the workspace to build the objects. Each set of extruders comprises a first extruder mounted to the extrusion head system; a second extruder mounted to the extrusion head system so as to be actuatable from a first to a second position; and a flexible linkage connecting the extruders. The flexible linkages position the second extruders in approximately equal known spatial relationships to the first extruders in the second positions.
