Hey everyone. I'm new to 3D design and my first product was met with mild success. I have a few questions that I was wondering could be answered by the more experienced community. First, what is the recommended plastic to use on Shapeways? I've tried the nylon with matte finish, but I don't particularly like the texture. Would the polished nylon be a better choice? Does this affect painting? Second, how well do small details show up using the recommended plastic? I have created a small articulated hand with some detailing that I'm afraid will be lost in the printing process. Lastly, does anyone know how much clearance should be used in ball joints to allow them to remain tight? I made the area of the negative space to be 1.1 times larger than the ball for my first print and it was too loose. I'm unsure what size to make it and was wondering if someone would have an idea. If I am unclear, please ask me to clarify whatever is confusing. I hope to get some good answers from you all! Thanks.
