Delta Plus is the most user-friendly 3D printer. Its modular design allows users to replace worn out parts and easily swap between printing materials by installing different cartridges. Changing cartridges is a tool-less procedure: the new cartridge will automatically re-initiate calibration and synchronize with the printer. The heated bed module helps improve the print quality by regulating the temperature of the printing surface and environment. The built-in air filter absorbs any unpleasant smells while printing. Delta Plus can be controlled through WiFi, bluetooth and even from the Cloud.
