RAPID MANUFACTURING OF TAILORED PREFORMS
A method for rapid manufacturing of three dimensional discontinuous fiber preforms is provided. The method includes the deposition of a polymeric material containing fibers on a surface to form a tailored charge for compression molding. The reinforced polymeric material may be a thermoplastic or a reactive polymer with viscosity low enough to allow flow through an orifice during deposition, yet high enough zero shear viscosity to retain the approximate shape of the deposited charge. The material can be deposited in a predetermined pattern to induce the desired mechanical properties through alignment of the fibers. This deposition can be performed in a single layer or in multiple layers. The alignment is achieved passively by shear alignment of the fibers or actively through fiber orientation control or mixing. The fibers can be of the desired material, length, and morphology, including short and long filaments.
Method and apparatus for automated composite-based additive manufacturing
An apparatus and method for the automated manufacturing of three-dimensional (3D) composite-based objects is disclosed. The apparatus comprises a material feeder, a printer, a powder system, a transfer system, and optionally a fuser. The method comprises inserting a stack of substrate sheets into a material feeder, transferring a sheet of the stack from the material feeder to a printer, depositing fluid on the single sheet while the sheet rests on a printer platen, transferring the sheet from the printer to a powder system, depositing powder onto the single sheet such that the powder adheres to the areas of the sheet onto which the printer has deposited fluid, removing any powder that did not adhere to the sheet, optionally melting the powder on the substrate, and repeating the steps for as many additional sheets as required for making a specified 3D object.
