Blocks of acrylic GS can be used very well as a solid construction material in model making. Because the GS material does not tend to melt when being machined, the building of transparent steel and glass constructions with lightly roughened acrylic blocks - especially in small dimensions - turns out remarkably well (sand with 400 to 600 grit paper).
Acrylic glass GS sheets and blocks are produced by means of liquid PAMMA polymerizing between two sheets of glass. This process produces a material with outstanding characteristics: it is fracture resistant (compared to glass), weather resistant, highly transparent and lends itself to being shaped and processed.
Acrylic glass GS can be milled, drilled and sawn and, as a thermoplastic plastic, can be shaped (deformed) at temperatures between 160 and 180 degrees. When processing it with a CNC milling machine please take into account the thickness tolerances (the variability) of the acrylic glass. The values for the possible tolerances can be calculated with the help of the following formula: Tolerance = ± (0.4 + 0.1 x thickness) mm. For intricate milling work like that which often is required in model making, we recommend you use cast PRECISION ACRYLIC GLASS.
