PEEK is an exotic material with exceptional strength, thermal, and chemical resistance qualities. In many cases, it is used in applications to replace metal parts.
High Heat Deflection
One of the most valuable qualities of printing with PEEK is its heat deflection. With a heat deflection temperature of 160C, PEEK is excellent for prints that need to withstand high heat.
What makes PEEK an exceptional material for functional use is its chemical resistance. This filament is known to not only bring strength but to not break down under extremely harsh chemicals.
