This Oscar3D MK8 ruby 1.75 x 0.40mm nozzle is ideal for intensive printer use. The core of the nozzle is ruby ground with a tolerance of ±10 micrometers. The hardness of the ruby makes the nozzle ideal for using materials that would quickly wear down ordinary nozzles. These can be materials such as carbon fibre or metals.
Using a ruby ensures a more constant temperature and more even temperature distribution. This reduces the chance of blockages. The Oscar3D MK8 is also equipped with an M6 brass screw thread with a length of 4.5mm.
