The technique of 3D printing using two or more filaments is known as dual extrusion. A print head with two extruders and nozzles allows you to blend colors or other materials. The printer prints from each loaded spool in turn, switching between them.
Although 3D printers have a reputation for being expensive, this is not necessarily the case in the modern world. If money is tight, you can get a cheap dual extruder 3D printer under $500 that performs just as well as the more expensive models available.

Like always, the answer to this query relies on the specific printing operations you need to perform. But, in general, dual extruder 3D printers are unquestionably helpful for more difficult projects, if not absolutely necessary in some circumstances.
