Use this to make length marks in standard SHAB test bars (for testing clay body or clay material drying shrinkage, firing shrinkage and fired porosity). This can be 3D printed. The markers are 10cm apart (outside edges). Most printers can achieve this measurement accurately. To be sure check yours using a caliper, if it is not close to 10cm adjust using sand paper or reprint using an adjusted dimension.

This is for making test bars of slip casting clays bodies for use in the SHAB test (to measure drying shrinkage, firing shrinkage and fired porosity). I designed it in Fusion 360 and 3D printed the light-duty rails and case mold. I poured plaster into that to make the two plaster working mold halves (top right). The funnels provide a reservoir so the bars be cast solid. This mold can produce a set of three bars in less than an hour.

This type of stamp is ideal for marking code number and ID information on SHAB test specimens (and many others) while in the plastic form. Set up the run or recipe number on the left and the specimen number on the right. You can find these stamps on Amazon by searching "12 digit rolling alphabet symbol number stamp".
