Design notes

This variety of Acrylic has a grey finish on one side and a clear glossy finish on the other. The grey side is the reflective coating that creates a mirror effect on the other side (just like standard glass mirrors).

Design files for mirror acrylic should be mirrored, otherwise they will be fabricated back to front.

By default, the material will be placed coated side up in the laser cutter, so any engraving will be on the coating. The engraving will remove the reflective coating making that section of the acrylic translucent.

If you want to engrave on the gloss side, make a note in the shipping instructions for your order. Engraving on the gloss side can only be done through the protective backing paper, so only heavy raster and vector engraving are suitable.

Acrylic retains detail when laser cut and it engraves well. For tips on engraving see this blog post. The engraving can be painted with great results see this blog post. for more information.

To determine the optimum engraving depth for your design, we suggest prototyping or purchasing a sample of this material from out sample store.

Acrylic is hard and stiff as plastics go. It is sensitive to stress concentrations sharing a certain fragility with glass. This is most evident if parts are small or thin. Details should not be smaller than 1mm/0.04" as they are likely to be too fragile.

Adding radii to corners can reduce the risk of breaking. For some tips on how to design for acrylic see this blog post. .

Acrylic has a thickness tolerance of +/-15% of the material thickness.

Acrylic can scratch easily and should be cleaned with a mild solution of dish detergent and warm water. Never clean with a other cleaners not suitable for acrylic or with a dry cloth.
