Professional dual-head 3D printers can 3D print in mirror mode with dual independent 3D extruders, while also allowing you to print two objects at once. In addition, you can easily print two different 3D models, using materials such as PLA and PVA, PETG and PVA or HIPS (for high temperatures) in combination with technical materials such as Carbon Fiber, ASA, and ABS. PVA and HIPS are soluble filaments, so with one session of 3D print, you can make the 3D model with its support.
