Misleading information on website, material section.

[JFD-Mtl]

Hi, the materials section of the website(https://docs.vorondesign.com/materials.html) has misleading information.

It says that the Nylon has a Tg (glass transision temperature) of 180C. That is false, it has a Tg around 60-75C but has a 0.45MPa heat deflection temperature of around 140-180C, depending on the type of Nylon and blend.

The Tg is defined by the softening temperature of the amorphous phase. A github ticket is not the place to give a course on semi-crystalline thermoplastics but it roughly means that the Nylon will only hold its shape up to 120-140C only when it is weakly loaded. Nylon's glass transition is not as sharply defined as other common plastics and creep increases significantly when its amorphous phase is softened. Hence I do not think it is wise to say it is a "viable option" for anything that is loaded, inside the chamber, especially on anything near the heatbed. I am not sure either where the comment about PA12 being more resistant to creep than PA6 comes from...

This section also says that the PETG has a Tg of 55-60, which is also false. It is around 80-85C.

I would change the Nylon paragraph for the following:
Nylon (PA6 and PA12) has a low glass transition temperature but some blends can withstand temperatures of 180C when under a minimal amount of load. It has moderate stiffness and moderate ductility. It is not recommended for Voron parts due to the tendency to creep (slowly deform) under the constant pressure exerted by the bolts clamping on the parts.
