Hey Brian.

Might want to fact/type-o check that article
Unlike the company’s other extruders, the Lite6 is not ‘all-metal’ since it uses a PTSE liner, meaning that there is a lower limit to the temperature it can achieve. For those worried about melting the liner, unlike many extruders on the market, the liner in the Lite6 can easily be replaced. In fact, a new liner will cost you under $0.50.
So...is it PTSE or PTFE? And does it really limit the LOWER or UPPER temperature?
