Three different candidate sacrificial materials were studied for this purpose: PEEK, PPS, and PC. Preliminary DSC test showed that the melting temperature of the PEEK was close to the range of the chosen resin.
According to the company, by introducing an all metal hot-end extruder capable of attaining temperatures up to 400°C (much higher than what is required to melt PEEK), their filament can be used.

Expandable Braided Sleeving. MONOFLEX™ PEEK is a great choice and delivers outstanding performance when it counts in the toughest aerospace, military, and marine applications. This construction provides abrasion and cut-through resistance in high-temperature environments. It is rated to 260°C and available in Black and Natural colors. For that reason, it is crucial to have good control of the temperature of your printing chamber. Given that the glass transition temperature of PEEK is about 150 °C and its melting point is around 343 °C, Solvay suggests the following temperatures as conditions for printing PEEK: Chamber temperature: > 180 °C; Bed temperature: 180 - 220 °C.

Plastics with low temperature properties. Most engineering plastics are generally well suited to temperatures below zero, although the extent to which this is the case depends mainly on the material and the specific application conditions. Due to the specific nature of thermoplastics, it is difficult to determine a low-temperature threshold.

Melting point of Polyamide - Nylon is 257 °C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition.

As a starting point, I recommend at least 130 F feed-throat temperature, unless you are dealing with a wax or some super-low-melting thermoplastic. From the point of view of venting (as noted above), warmer is better. If the polymer has to be dried, the feed zone could certainly be set 10° to 20° F lower than the drying temperature.

The melting point (or, rarely, liquefaction point) of a solid is the temperature at which a sustance changes state from solid to liquid at atmospheric pressure. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at standard pressure.
