Prusament PLA Azure
Well behaved and gorgeous sheen in the light
Polymaker PA6 Carbon Fiber
Stiff and nice sheen, but some cooling and stringing issues. Filament snapped and lost part of a layer because the sample wasn't on a spool
Polymaker PA6 Glass Filled
Stiff but poor cooling on smokestack
Tecbears PETG
Stringy, but shiny surface finish. A few zits in the hull too, but a solid print
Tecbears TPU 95A
Poor bridging, needs more cooling, and lots of stringing between gunwales and cabin. Also, fairly stiff for a 'flexible' filament
Polyterra Green PLA
Tested out my filament dryer, reduced the stringing
