Built up lettering and logo's give a dimension and a solid appeal reflecting quality. Built ups can be internally illuminated using neon or LEDs, to give a 'halo' or face lit effect.
Built ups are normally made from acrylic, de-scaled stainless steel, but can be manufactured in other materials.
Acrylics can also be vacuum formed to create 3 dimentional objects which are attractive and relatively inexpensive to mass produce.
