Design notes

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.

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.

Would it be correct to assume that the matte side is up when cutting? ;)

Yes that is correct - the matte side is up when cutting & engraving. Thanks for clarifying!

Does this matte acrylic reduce the fingerprint marks that are left on regular, glossy acrylic?

Hi - In our experience there are hardly any fingerprints left of the matte side when compared to the glossy acrylics.

If I want to heat bend this material, what temp is required?

Hey Steve -

You can bend acrylic using a heat gun or an oven at 175F - 200F.

We don't have much first hand experience with this, so you'll want to start at a low heat and go from there.

I hope that helps for starters.

Cheers,
Dan

Dan, thanks for the info. On your advice I tried the oven method and found 200F would soften the materials a bit but not enough to form a tight corner. After some experimenting, 300 for 15 minutes (for a 3mm piece about 3"x5") was just the ticket. I was able to form the material into a nice tight 90 degree corner.

Also, over 350 causes the material to bubble (bummer) and be ready to work fast. the material starts to loose its flexibility very quickly.

Steve -

This is great! Thanks so much for taking the time to share this with us.

I've updated our notes on our end, so we've got these temps ready for next time.

Can't wait to see the final project!
