3D Printing at a scale greater than a couple of parts is often referred to as Additive Manufacturing .
Selective Laser Sintering (SLS) can be thought of as an injection molding machine without hard tooling. Thin walled, plastic parts at a low volume are affordable, tool-less, and give you the strength and durability of Nylon.
A build size of 17x13x11" can handle a number of parts at once. Part builds can be turned around in as few as 2 days for dozens of parts.
Ask about painting, dyeing, and moving assemblies printed as a whole. There are so many applications and design freedoms gained from an additive approach.

We can even make SLS parts look great for photography and market research which has historically been the weakness of SLS technology.
