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

Orders using this material generally ship in 1 week. Find out more.


Design notes

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.

Typical uses

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.

Environmental info

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.

Tips from other designers

Alex says:

Curious how flexible the thinnest acrylic you offer is, the 1.5mm sheet. If i get the P3 size (approx 31 inches by 15 inches), and you held it up by the center, how much sag would there be on the longer dimension at the ends? I am trying to recreate an acoustic lens and need thinness and rigidity (not so much strength) where originally metal sheets were used.

The 1.5mm acrylic sags by ~2 inches at each end when held as you described.

Do the custom acrylic parts come with finished edges like the sample piece does, or do customers have to finish the edges once the piece is delivered?

Dan says:

The images and samples show how the material comes off the laser cutter, without any additional finishing. With acrylic the finish is similar to flame polishing.

" Acrylic has a thickness tolerance of +/-15% of the material thickness. " what does this mean? does it mean that the 3mm thickness can actually be anything between 2.55 to 3.45mm ?? can this never be guaranteed ??

@Akin - that is correct, the thickness can be between 2.55 to 3.45mm. This is the tolerance that the manufacturer makes the acrylic to and is typical among different manufacturers.

Generally the thickness is not at the extreme ends of the spectrum. 2.7-3.3 is more common.
