​3D printing has been around for nearly 40 years, but its only in the more recent history of the evolution of 3D printing that we’ve really seen 3D printing changing manufacturing in major ways.

Channels are integrated into molds and die so that they dissipate heat more quickly, reducing the cooling time needed for the part and the tool. This makes it possible to crack open the mold or die and inject more material for faster production.​

Several manufacturing technologies exist for making plastic parts. All over the world, injection presses, 3D printers and CNC machines are at this moment cutting, extruding and forming plastic into usable parts. All are highly useful machines, all of which offer their own particular advantages.
