The UltiMaker Factor 4 is capable of reaching 340°C using the UltiMaker HT core. The UltiMaker HT core is an abrasion resistant print core, with a similar TIN-coated tool steel nozzle as CC print cores. The heater block of a HT core is made of copper, instead of an aluminum. This allows print temperatures up to 340°C.
HT core is available with a 0.6 mm nozzle size.
