I am with a small design consulting firm who is looking to build a materials samples library. We’re looking for good sources for free or low cost material samples of metals, woods, plastics, rubbers, finishes and coatings, composites, ecological…pretty much anything and everything. Any suggestions?? Thank you.
Not free by a long shot, but might be useful anyway (maybe they’ll lower the cost or offer just the research): http://www.inventables.com/
