In July last year, UPS started to offer a 3D printing service to the masses, and taking into consideration that such an effort was in its infancy back then, it made plenty of sense to see the 3D printing service being limited to just several stores and not see a widespread adoption rate. However, it looks like the experiment to deliver in-store 3D printers apparently went on just fine, and UPS has decided that it is time to start expanding the availability of the vaunted 3D printing services.
