TEST METHOD, TEST DEVICE AND EVALUATION DEVICE FOR RESIN FILAMENT

摘要

To provide a test method for resin filament that contributes to an improvement of molding processability by a 3D printer.SOLUTION: The present invention provides a test method for evaluating a resin filament F for a 3D printer, in which a filament feed part 4 is set to a predetermined feeding speed Vo, the resin filament F is fed into an extruder 1, and is melted by the extruder 1. While extruding from a nozzle 2, an actual feeding speed V of the resin filament F and a pressure load Tq during feeding are measured over time with respect to the feeding speed Vo by the filament feed part 4.SELECTED DRAWING: Figure 3
