Process Monitoring of Extrusion Based 3D Printing via Laser Scanning
Extrusion based 3D Printing (E3DP) is an Additive Manufacturing (AM) technique that extrudes thermoplastic polymer in order to build up components using a layerwise approach. Hereby, AM typically requires long production times in comparison to mass production processes such as Injection Molding. Failures during the AM process are often only noticed after build completion and frequently lead to ...
متن کاملVision based error detection for 3D printing processes
3D printers became more popular in the last decade, partly because of the expiration of key patents and the supply of affordable machines. The origin is located in rapid prototyping. With Additive Manufacturing (AM) it is possible to create physical objects from 3D model data by layer wise addition of material. Besides professional use for prototyping and low volume manufacturing they are becom...

The Three Dimensional Printing (3DP) Process hasbe~nadapted for processing of fine ceramic powders to •• prepare structllraLceramic components. Our preliminary study was designed to reveal those aspects ofthe.3DPprocesswhichmust be modified for use with fine ceramic powders. The basic elements of the modified process are to spread submicron alumina powder and printJatex binder. Several methods ...
متن کاملProcess Parameter Optimization of Extrusion-Based 3D Metal Printing Utilizing PW–LDPE–SA Binder System
Recently, with a broadening range of available materials and alteration of feeding processes, several extrusion-based 3D printing processes for metal materials have been developed. An emerging process is applicable for the fabrication of metal parts into electronics and composites. In this paper, some critical parameters of extrusion-based 3D printing processes were optimized by a series of exp...
متن کاملOptimal Offline Compensation of Shape Shrinkage for 3D Printing Processes
Dimensional accuracy is a key control issue in direct 3D printing. Part shrinkage due to material phase changes often leads to final shape deviations, requiring extra postmachining steps for correction. Shrinkage has traditionally been analyzed through finite element simulation and experimental investigations. Systematic models for accuracy control through shrinkage compensation are hardly avai...
