Well, I believe polymer chain alignment is used quite a lot in manufacturing to improve strength in the desired directions. However, given that I couldn't see any info on what this '3DRSR' actually is, I am also sceptical. At the end of the video the bloke mentions needing to pay for tooling.... is this for their '3DRSR' machine, or do you need tooling to be made for each 3D printed part, in which case it isn't really 3D printing?

Sounds rather like they're throwing in some buzz words to make their plastic moulded wheel sound cool.
