A clear thermoplastic with a reflective backing on one side. Coloured Mirror Acrylic has a grey or white finish on the back and a clear glossy finish on the front. This reflective coating creates the silver mirror look through effect. Hard, stiff and sensitive to stress concentrations. This is most evident if parts are small or thin.
Mirror Acrylic sheet is supplied with a protective plastic film on the glossy side. When only laser cutting is required, we cut with the reflective side up leaving the plastic film on. We also apply protective paper backing to the reverse side. This helps to reduce heat marks and protects the surface from scratches.
Cut widths & Kerf
As a benchmark, we recommend that minimum cut widths be no smaller than the corresponding thickness of the material. For example, if cutting from 3mm acrylic, its best not to allow anything less than 3mm in width. We can go smaller but this can make your components quite fragile which might not be suitable for the application. See more on cut widths and Kerf (how much the laser takes away.)
Acrylic laser cuts with a highly polished edge. We achieve this using a high laser frequency (ppi. pulses per inch ) that melts the edges as it cuts. If you look closely at the edge it is not entirely smooth and is made up of lots of tiny vertical lines. This is caused by the pulses of the laser.
We have established optimised engraving settings for all our supply materials. On all mirrored acrylic the engraving is carried from the reverse / non reflective side. Prior to this (if you have not done this already) we will “mirror” (reverse) your artwork so that it remains the right way round when viewed from the reflective side. The engraving setting is optimised to remove the reflective coating from the reverse producing a look through effect on the mirror side. We keep the protective film on the reflective side to protect the surface from markings when cutting is also required.
Vector engraving is also carried out on the reverse side of the sheet.
