This will be my first time getting something made with 3D printing. My design is basically a electronics enclosure, it will have buttons which will also be 3D printed The material I will choose will probably be the black detailed plastic I did consider another company, they had a minimum volume requirement that made it annoying to create buttons. Do you have any such requirements? I am using SolidWorks. Which axis do I need to specify as the vertical axis? Or is this determined by your machine automatically? Is the volume of the design calculated using the amount of model material or the model material plus the supporting material? If it is the combination of the two, is it possible to optimize the cost by putting multiple designs into one file in a compact way? Is it better to upload each solid object as a single file? Or can I combine all the solid bodies into one file? Thank you.
