hello everyone, I am a toy designer working with another 3D artist to build a number of action figures that I wish to have printed through shapeways. I wish to get your feedback on what the resolution should be on the components that will make up the figure. the figure is 6" tall and made up of the following pieces: Head Torso Shoulder joint x 2 Upper arm x 2 Forearm x 2 Thigh x 2 Calf x 2 Foot x 2 Hand x 2 Should the file be uploaded in pieces? or one entire file? Thank you, I am not sure how to go about doing this.
