As a long time user of 3D hubs, I describe it to colleagues as the Uber of 3D printing. You upload your model, have people bid on your project and completion date and then order them. Huge success using this service and you will too! The easy to upload and get a quote has been super helpful to our design practice. Review collected by and hosted on G2.com.

Some people might say this isn't "instant" in terms of having the printed model in your hands right away. While that's true, its not a big deal to wait a few days for it to print and ship. Review collected by and hosted on G2.com.
