An anonymous tipster has provided the solution to last week’s Solidscape event.
We were directed to a patent describing a composition for 3D printable concrete. This would certainly be a very useful capability, as the many attempts at 3D printed buildings using concrete extruders have had mixed success. However, most, if not all, of them have been using standard concrete materials. We know from experience with thermoplastic… Continue reading Look Who’s Patented 3D Printable Concrete

It may be in their self-interest, but they have a valid point. The infographic indicates that a surprising amount of newly released products are subject to recall… Continue reading Autodesk Battles Bad Design
If you’re using an extrusion-based 3D printer, you’re likely familiar with the problem of seams. It’s an annoying strip right up the side of your object that disrupts the otherwise smooth surface of your 3D print. The seam is actually composed of the vertical accumulation of start / end points from each layer’s perimeter.… Continue reading Stratasys Solves Those Troublesome 3D Print Seams

This was totally inevitable. Earlier this week a new object posted to Thingiverse was widely discussed. It was a great object – apparently able to visually simulate an impossible object: The Penrose Triangle, except in reality. And the design succeeds, at least when viewed from the correct angle. But then the fun started. Ulrich… Continue reading 3D World Gets DMCA’d
We’ve just been going through a rather lengthy patent application submitted by Eduardo Napandensky and Diana Ravich – and the patent is assigned to Objet Geometries, one of the top line commercial 3D printer manufacturers.

We’ve been wondering how property rights will work in the future, when anyone will be able to punch out objects on their 3D printer as necessary. Will you go to Home Depot to get that bolt? Or perhaps you will just print one? Do you have the design for the bolt? Maybe you need to… Continue reading Fab-onomics
It’s not exactly Fabbing as we know it, but the World Intellectual Property Organization now includes an entry on printing live tissue. Yes, I mean punching out “mammalian cells” via an ink-jet process. Evidently the cells are deposited in layers, much like 3D printing, onto an existing substrate. In some cases the substrate is itself… Continue reading Printing Tissue by Ink-Jet
