-The most common question asked when selecting an advanced filament is "What is the maximum temperature <plastic> can handle?" While the question is reasonable, it is completely unanswerable.

 Broadly speaking, the higher the temperature rises, the weaker the plastic becomes. This often happens gradually; therefore, the higher the strain in an application, the lower the "Maximum Temperature" is considered to be.

 Some plastics also exhibit [[wp>Creep_(deformation)|creep]], a situation where a plastic component slowly deforms in response to continuously applied force. This effect can also vary with temperature.

+===== "Optimistic Usable Temperature" =====
+This phrase is commonly found on this wiki and generally refers to the temperature that a well-calibrated print at that temperature can support some loads (e.g. AB Motor mounts on Vorons) at that ambient/chamber temperature.
+This number lacks a certain //scientific rigor// and should only be used as the starting point for your own research.
+===== Takeaway =====
 Identifying the "Maximum Temperature" of a particular polymer for a particular application is non-trivial. While datasheets or HDT testing can provide critical inputs or points of comparison, no one number is likely to provide directly applicable data for your project.
