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.
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 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.
Please note: The laser cuts at a slight taper (1-2 degrees) since the laser beam is shaped like a cone. The tapering causes one side to be slightly smaller than the other side. The taper is almost unnoticeable in 1/8" material; the thicker the material, the more noticeable the taper. When using laser-cut parts such as wheels or gears, you might need to position the parts in an alternating pattern so that the tapers “cancel out”.
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.
Adhesives, joints & fastenings
Acrylic can be joined with epoxy, Weldon 3, 16 and 40. Dichloromethane and chloroform. Screw joints should be pre-drilled to avoid splitting.
