Did someone ever try to use a 3D printing pen to fill-in those nasty seam lines that a printed 3D model has on each layer? Usually I sand them away after optionally filling them with super glue and baking soda. I wonder if closing the gaps with a 1.75 mm filament compatible pen could be an option, as I could use the same filament used to print the model. #3Dprinting#3Ddruck#PostProcessing#Nachbearbeitung
