Item type:Publication, Access status: with files , Experimental and analytical investigation of cemented tungsten carbide ultra-short pulse laser ablationUltra-short pulse laser processing of hard materials, such as cemented tungsten carbide, requires an accurate and agile experimental and analytical investigation to obtain adequate information and setting parameters to maximize ablation rate. Therefore, this study presents a systematic approach which, first, experimentally searches for the variables with the most significant influence on the objective using a design of experiments method; and second, analyzes by means of existing ablation theory the interaction of the material and laser taking into account the Beer-Lambert law and incubation effect. Therefore, this places a basis for future analytical-experimental validation of the examined material. © 2013 The Authors.Publicationtype: Conference PaperScopus© Citations 20 235 312 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Laser additive manufacturing of gas permeable structures(Elsevier, 2013-04-09); ; ; ; Laser additive manufacturing offers a variety of new design possibilities. In mold making laser additive manufactured inserts with conformal cooling channels are already state of the art. Pneumatic ejectors for injection molds are a new application for laser additive manufacturing. The pneumatic ejectors require a durable gas permeable material. This material is produced by placing the scan vectors for the laser additive manufacturing process in a defined pattern. Trials with different plastics proofed the function and reliability of the pneumatic ejector concept in the injection molding cycle. © 2013 The Authors.Publicationtype: Conference PaperScopus© Citations 15 294 252
