Thanks for taking the time to visit this post. I'm a newbie here and to 3D printing in general. My background is in Aerospace and one of my graduate degrees is in Materials Science. I'm here in part to learn more but also to explore my entrepreneurial itch. I've assembled a team of other mechanical engineers and materials science guys to start tackling some problems we've encountered. I would also like to dabble in this arena. So I'm here to ask what problems you guys see that could be solved? Or to phrase it a different way, what sucks about 3D printing? Any help is greatly appreciated. Thanks.
