3" Clear Acrylic Sheet
Color 000 · 3" thick
3" Clear transparent acrylic (plexiglass), cut to your exact size from 11″ to 48″ per side. Choose a standard size or enter custom dimensions, add flame- or diamond-polished edges, and see the price instantly.
3" clear in practice
Transparent stock at 3" reads as a piece with visible depth, where the edge color and the thickness itself become part of the look.
This is heavy plate. It behaves like a block: it can be machined, polished on the edge and stood on its own, and both the weight and the price scale accordingly, so size it deliberately.
In a laser: a CO2 machine cuts this cleanly and leaves a flame-polished edge, though at 3" expect slow, multiple passes and plan for a wider kerf. A diode laser will not cut it at any setting — the beam passes straight through transparent acrylic.
3" clear (color 000) starts at $6952.96 for a 12″ × 12″ piece at this thickness, and weighs about 18.71 lb per square foot, so a 24″ × 48″ piece comes to roughly 149.7 lb — worth knowing before you size a panel someone has to lift or ship.
Special order · sourced to order
This thickness is sourced to order, not held in stock. Once your order is placed we confirm availability with our suppliers — lead time runs longer than our stocked thicknesses and is confirmed per order, and if the material cannot be supplied we cancel the order and refund it in full. Sizes too heavy for parcel shipping go by LTL or FTL freight, quoted separately and agreed with you before the order is finalised; if timing matters, contact us before ordering and we will check availability first.
Why 3" clear acrylic?
At 3″ the material is genuinely optical. Light entering the face travels through real depth before it leaves, so an object set behind or inside the block appears to float, and a machined feature — a bore, a chamber, a lens seat — has a visible interior you can inspect from the side. That is why it is specified for optical blocks and light-guide prototypes, for viewing windows in tanks, chambers and enclosures where a single monolithic panel is wanted rather than a laminate, and for the vitrine bases and museum-style pedestals that need to read as solid glass. Machining is slow and deliberate at this thickness: cuts are taken in passes, heat is managed, and a polished edge takes real time — plan the part around that.
About Clear acrylic
Clear acrylic is the original — optically clean, about as transparent as glass but roughly half the weight and far harder to shatter. It's the default for glazing, display cases, tabletop covers, sneeze guards, and picture-frame glazing: anywhere you want the material itself to disappear and the contents to be the show. Polished edges on clear stock look like water.
Made to order. Not every color and thickness is stocked at all times — if yours is temporarily out, we make or source it and ship as soon as it's back in stock. On a deadline? Email us before you order and we'll confirm your expected ship date.
