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.en1875-38922013873880Elsevierhttps://creativecommons.org/licenses/by-nc-nd/3.0/Laser Additive ManufacturingGas Permeable MaterialInjection MoldingPhysikConference Paperurn:nbn:de:gbv:830-882.03572110.15480/882.227710.1016/j.phpro.2013.03.16110.15480/882.2277Other
