You can send us pretty much any format – Maya, 3ds Max, Zbrush, Mudbox, Modo, and we’ll clean up and prep the model and make sure that it is watertight, scaled, articulated, cut up for manufacturing, etc. before sending to the printer.
The files that get sent to the printing facilities are either STL or OBJ, but we prefer to work with a native format – that is, whichever program you used for the modeling, we’ll attempt to use the same software.
