Not for the 3D printing beginners! Filament in this category will require more patience and understanding, but enables you to get the best out of your printer. Products vary from flexible filaments, to stronger thermoplastic and filament with metal powder.
How much 3D printing experience is recommended before using this material.
Determines how easy the material adheres to the printbed and can be removed from the bed without damaging either the bed or the print.
How tough is the material. From 1 star (very brittle) to very tough
The speed at which the material can be extruded. This is determined by how fast it melts and how viscous it is.
How much smell does the filament produce while printing and how bad is the smell. More stars is better
The amount of energy that a material can withstand when a load is suddenly applied to it. It may also be defined as the threshold of force per unit area before the material undergoes fracture/
How well can the material handle temperatures before it starts to deform.
