Capture - If your desired print is of something that already exists, like a human or dog bowl, the first thing we need to do is make a digital 3d model of it. This is called capture and there are a few ways we do this:
3D laser scanning: scan object, no larger than a car engine, with a 3D scanner. Here we use a Kinect scanner with Artec Studio 9 software.
Photogrammetry or Image Based Modeling: Thus uses photos to create 3D model. Photograph object, any size, from multiple angles, run photos through software suitable for processing images into a 3d model. Here we use VisualSFM software. Models could also be made from a series or MRI's or CT scans.
Modeling - If your desired print is an "idea" of something you want printed for rapid prototyping or other uses, programs such as Rhino, Blender, Solidworks, Sketchup are used to build the model from scratch. Here at Photo and Imaging, we use Non-uniform rational basis splines (NURBS) to create and edit models. We then convert models into a mesh and prepare it for printing. Once a mesh, the model is made up of no curves but faces that make up a curve whose resolution is controlled by the polygon count (more polygon faces make up a smoother curve). These faces can be edited in programs such as Blender. Adding solid surface texture mapping, color, motion and environments for presentation purposes are also part of the modeling process.
Downloading printable files - If you found something on the web and would like it printed just download the (stl) file associated with the model you found and send it to us.
