Abstract

3D - Inline - Process - Control is getting more attention in any fields of manufacturing processes to increase productivity and quality. Sensor systems are necessary to capture the currently process status and are basement for Inline-Process- Control. The presented work is a possibility to get inline information’s about the additive manufacturing process Fused Filament Fabrication. The requirement is the ability to manipulate the machine code to get free field of view to the topside of the object after every manufactured layer. The adaptable platform layout makes possible to create different approaches for inline process control. One approach is the single camera layout from bird view to get 2,5D information’s about the manufactured object and the other one is the active stereoscopic camera layout with pattern projection. Both approaches are showing a possibility to get information’s of the manufactured object in process. Additional this cases allow a view inside the manufactured object and defects can be located. Deviations in the manufacturing process can be corrected and relevant parameters can be adapted during slicing process to increase the manufacturing quality.
