Unfortunately complex and intricate is not something that goes hand in hand with 3D printing. The currently available printers work off a process called FDM (Fused Deposition Modelling) which basically lays down layers of melted plastic from a nozzle. It's technology that's been available to industry for years. So far, the best process I've used for intricacy is SLA (Stereo Lythographic Assimilation), but the resultant parts are extremely brittle as they're made from a laser-cured resin. Mid-way is SLS (Selective Laser Sintering) which uses a laser to fuse polymer powder into the required object. Much tougher parts, but the surface finish is rough, and intricate detail is not so sharp.
Rapid prototyping processes all have their pros and cons, but certainly you're not going to get much more than simple novelties from home 3D printing.
