Here’s an in-development resource that attempts to help customers compare and contrast all desktop 3D Printers currently available: Makerwise 3D Printer Guide:

We’ve been following the 3D printing movement with great interest and like so many we’re very excited about its potential. But as new and innovative 3D printers are continually introduced, it’s becoming more difficult for potential buyers to keep track of their performance, quality and availability.

That’s why we set out to create this objective guide of each and every commercially available 3D printer out there. It is our goal to make this a platform where any individual or company will be able to find the 3D printer that fits their specific needs. So whether you’re a student, engineer, designer or just a tinkerer, we hope this site will prove useful in navigating the amazingly diverse world of 3D printers.
