You can indeed get it printed it fully-formed on its landing gear. The best people to direct this question to, though, is the company you're thinking of using. They'll be best placed to answer questions regarding the capabilities of their 3D printers.

Printing this fully formed on your typical hobbyist 3D printer that fuses filament would be difficult and require several hours of hand-finishing to get it to an acceptable level. However, there are other technologies available at a commercial scale (such as SLS, or selective laser sintering) that are up to the job. Caveat: the landing gear may come out a bit fragile.
