The SPARKX i7 uses an integrated hotend, which combines the nozzle, hotend, heat break, and heat sink into a single assembly. The printer is shipped with a 0.4 mm integrated hotend as standard. In addition, the i7 also supports 0.2 mm, 0.6 mm, and 0.8 mm integrated hotends.
Different hotend diameters are suitable for different application scenarios. Please refer to the notes below for usage considerations for each hotend size.
