We recommend using wear-resistant nozzles made of tungsten caroffere or hardened steel to print engineering materials and replacing them regularly.

Engineering materials have high shrinkage stresses and are prone to cracking when printed at low ambient temperatures.Therefore, closed printers or thermal enclosures are required for printing.Open prints have a higher failure rate;
