Acrylic - Black (Matte 1-Side)
What is it
Acrylic (PMMA) is a thermoplastic that is available in a wide range of colors including transparent tints and clear to opaque solid colors.
This variety of Acrylic has a matte finish on one side and a glossy finish on the other. By default the material will be placed matte side up in the laser so any engraving will be on the matt side. if you want to engrave on the gloss side, make a note in the shipping instructions for your order.
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.
Acrylic retains detail when laser cut and it engraves well. For tips on engraving see this blog post.
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.
Acrylic is commonly used as signage, glazing and in building applications, fabricated point of sale displays, menu holders, display cabinets, machine guards, furniture inserts, aquariums & fish tanks, jewelry and tableware.
Acrylic is non toxic and recyclable in some areas.
