Acrylic is a plastic (Polymethyl methacrylate to be precise), and is sold under trade names of Perspex, Plexiglass, Oroglass, and many more. It is available from 1mm thickness through to 30mm, in an amazing range of colours and transparencies.

We stock clear, white, black and a small range of colours from 2mm through to 5mm thicknesses, but have a fantastic range of suppliers to order in specific colours, effects, thicknesses or sizes in for you specific needs within a few working days.

The material has a protective film on both sides, to protect it from scratching it’s highly reflective surface, we leave this on if only cutting is required. If vector or raster engraving is required, we remove this film from one side and slight residues from the laser process may remain on the surface which can be removed afterwards.

Cutting this material with a laser leaves a polished smooth edge, but on thicker material it can be noticeable that this smooth edge is made up from small vertical lines caused by the pulsing of the laser beam, we minimise this as much as possible, if a very smooth edge is required, let us know.

It can also be cut effectively with a CNC for sheets that are larger than our laser bed, or thicker than 10mm. It doesn’t leave as much of a polished edge as the laser, but we can advise you on how this can be smoothed off.

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 (see cut width image above) but this can make your components quite fragile which might not be suitable for your application – we cannot guarantee any pieces staying together which are thinner than 1.5mm or the thickness of the material, whichever is greater.

Acrylic is a thermosetting material and can be brittle and crack if placed under stress.

Acrylic sheets are either cast or extruded. Cast is slightly more expensive but is stronger, has a better visual appearance and is available in a wider range of colours. As it is a cast material, it is advised that it can vary by +/-10% plus 0.4mm (e.g. 8mm cast sheet could vary from 6.8mm to 9.2mm), so bare this in mind if pieces need to perfectly fit together and incorporate this tolerance into the design.
