These are the Cadillac of 3D letters and are produced in a multi-stage process. First, a thick sheet of acrylic is laminated with an alluminum sheet. The letters are then cut out with a CNC guided router which leaves a small lip on the back of the letter. A matching CNC cut is given to the skin of the wall/ counter that the letters will go on. The letters are pushed through from the back side leaving about a 1/2 inch of exposed clear edge. The whole thing is illuminated from the back side creating a beautiful halo light effect.
