3D Hubs Talk

I'm new at this with 3D printing. I'm going to make a new pump wheel to our old dishwasher. It's only 20 year old so I think it's too early to buy a new one, and I also thinking about the nature whit alls this electronic junk. My question is what material I'm going to use? The original is in some sort of plastic.   Is there some good tutorials I can read on Internet?  
I'm looking for a simple way to create surface nurbes (iges format) from my scans to import into solidworks. I've been through all the solidworks solutions to no avail. I do simple but organic sheet metal scans with no intent to print. Obviously free solutions always welcome but cheaper solutions more realistic. Geomagic gets a lot of mention but at $10K it's not doable. Thanks for all your help.
MakerBot is hosting a series of Makeathons this summer to help educators bring 3D printing to classrooms across the country. Over the course of a weekend, we will collaborate on projects and lesson plans in STEAM subjects. You do not need to be a teacher to attend, just someone with some level of experience in 3D printing and an interest in helping educators.  
Hi, my name is Vadim and I'm a freelancer from Ukraine. I would like to offer my services. More than 3 years I've been working with computer graphics and I'm experienced in creating models for 3d printing. I work with CAD (SolidWorks, КОМПАС 3d, AutoCAD, Rhino) and also: Maya, Blender.Primarily specialized in the engineering and architectural directions. Here you can find samples of my works:
Yep, that's right! Turns out PLA is not only stronger than expected at the human-scale, but is also buoyant!   Last week we had the pleasure of taking our intern Akshay's inspired 3D printed surfboard out on the waves in Sligo, Ireland. Seven surfers took it out in two locations and were able to stand up & hang ten.
