3D Printer Filament is not round!

[JohnA136]

Another issue is with the amount of filament being extruded. Your software will use the diameter you input to calculate how much plastic to extrude.

I agree that there is a good deal of China bashing going on in all fields. I suppose the best estimate of how good Chinese filament is, is its price. If it is selling at an equivalent US of European price, then there is a good chance it is OK. If it is cheap, then expect it to perform cheaply.

I think there is something that goes something like you get what you pay for. Like any country, there are a few shady characters that want to make a quick buck, or Yuan, and don't care about repeat customers, or quality. However there seems to be developing a supply base of quality products coming out of China, maybe. I seem to remember something like this in the early 60s (I know the Jurassic) when Japanese products were really poor quality, now Japanese stereos, and cars are some of the best. Do the Japanese make 3D printers ?
