such as a bolt going through the mounting holes 11 on the sides of the stable mesh can be used the cast volume 29 contains stable mesh structures 5 and stable mesh openings 15 fig4 shows a detail of the stable mesh 1 illustrating the stable mesh mounting holes which are used to attach and register the stable mesh to the mold also shown are the stable mesh sheet fiducial 16 and the master pattern fiducial 27 the easily observed stable mesh fiducial is in a known relationship to the master parent fiducial fig4 also shown the stamp material hatched area and its relationship with the master parent 26 and the stable mesh openings 15 fig5 shows the finished stamp 30 after removal from the mold with the stable mesh 1 and a surface pattern 33 cast by the master parent fig6 shows a second embodiment for the mesh pattern for the stable mesh 1 inside the finished stamp 30 with the surface pattern 33 cast by master parent after removal from the mold fig7 shows a third embodiment for the mesh pattern for the stable mesh 1 inside the finished stamp 30 with the surface pattern 33 cast by master parent after removal from the mold referring now to fig8 a and 8b the stabilizing effect of the mesh on the pdms stamp will now be shown the invar stable mesh is strongly resistant to deformation due to changes in temperature or moisture content of the stamp in response to environment or applied heat including radiation.
