I’ve recently had the opportunity to try the Ciclop, an open source hardware desktop laser scanner. The recommended software is Horus, which will export a colored point cloud in .ply file format. You can’t print a .ply directly, because the slicing engines available are designed to work with manifold surfaces, like those found in good .stl’s, .obj’s, and .amf’s. As Horus is developed, I think we will see more file processing options, like trimming, alignment, “fusing”, “flattening”, hole filling, and other various file-prepping tools. In the mean time, Meshlab and Blender offer these tools, and can be used to make printable files from point cloud data.
Nothin’ to it but to do it!
First: let’s just open the file in blender and isolate some patches to see what we are working with. tab gets you into edit mode for the selected object. a deselects everything. c or b can be used to do a circle select or border select. Scroll the wheel to change the size of the circle and hit esc when you are finished selecting. shift+h hides all but the selection. alt+h shows everything.
