    This C-Arm model was designed for SLS 3D print, designed with integral pivots and linear tracks.

    Interesting. Not sure what the 7-degrees of freedom can do.

    Looks to me like it could be used in some kind of medical imaging device.

    These images were posted over two years ago, and yes it looks like a medical x-ray device with the source and detector on opposite ends of the C-shaped part that swivels around the patient.

    Makes sense. Thanks!

    This is the problem with people using "model" these days without specifying the scale. "Model" is inherently ambiguous: either a representation or a prototype (or a product of certain specification, such as "year and model of a car").

    This is a concept (C-arm) model of an imaging device. OK. But when one says it's a printed model without specifying the scaling down concept, I would presume in this context it uses 3D printing technology to achieve certain useful function. This post is a good demonstration but has bad explanations.

    In all fairness the images may have been quickly posted for a specific customer or potential customer with no explanations required, or to just highlight some specific elements that can be achieved with 3D printing for some other project. It may not have been posted for anyone connected to Shapeways or other shop owners to admire. It's not even in the poster's shop.

    As far as the device itself goes it appears to be the moving parts of something called a Mediguide system used to help physicians navigate the movement of catheters inside subjects. Instead of using constant X ray emissions it uses a low level EM field in combination with sensors on the probe that locates the probe spatially in 3D space. It only takes X ray images once in a while to calibrate the subject with the probe location to help physicians guide the probe properly.
