A question came up at the office today, and, knowing as they do of my dallying on a questions message board, my colleagues asked me to ask you.
We were examining an acrylic desk, uh, object to display. It’s clear acrylic, with a 3D (not truly, just graphically) map, what appears to be a clear plastic strip with black lettering on it, and a company logo embedded. Dimensions are approximately 3/4" D x 4" W x 5" H.
While my colleague who possesses it described how the creating artisan had carefully mounted the 3D map at 2º off the plane of the obelisk, to create a lens effect enhancing the 3D imagery, on close inspection, no, Larry, you’re a good exploration geophysicist, and that’s why you say these things. The map appears just very slightly warped, as a piece of paper lying “flat” on water might.
The company logo appears to be more rigidly planar and the strip with lettering looks to be of the type one might get off of something like a Kroy lettering machine. It is mounted in a plane 90º away from that of the map and the logo.
While I’ve seen many metal objects (little metal baby drilling rigs and the like) embedded in acrylic cubes, spheres, etc., I never really wondered too much about 'em. But this one (and another popular in my biz - an acrylic with a perfect teardrop shaped airspace filled about halfway with oil) has me wondering.
Close inspection revealed no seams. I’m guessing that since heat would damage some of the embedded objects, and the teardrop airspace is otherwise a mystery, this must be a case of whipping up a cool slurry that can be slow poured into a mold, where it then sets.
But I don’t know that.
So OK, TM, how do they make these things?
