Greetings! When your parts demand high-performance materials like PEEK, PEKK or CF/GF-reinforced polymers, you must pick a machine built for high temperatures, stable environmental control and strong material profiles. Look for specs like 430 °C extruder, 90 °C chamber heat, robust bed and frame etc. The Epitum line from UAE addresses these kinds of uses: large build volume, composite materials support and industrial design. Their blog gives excellent explanations of how they meet engineering-material needs:
