An interesting fact about white filament

So I’ve worked in plastics for quite a while, up until a few years ago it was only known within the industry that white plastics are made using titanium dioxide, now in 3D printing it’s pretty common knowledge.Amazingly I’ve only just realized it’s Mohs hardness is actually higher than brass, so it should be abrasive on regular nozzles. I asked a guy at the filament company I use a lot and he told me that common grades are coated to prevent clumping, which has the side effect of lubricating the TIO2 to prevent the abrasion. Just something interesting I learned I thought I’d share. https://ift.tt/2RBtNAY
