Double sided, the designs shows on both sides.
12x19 inches. Materials are advertised at 12x19 inches. There is some variation though due to the manufacturing and cutting process that can result in pieces being narrower in some cases. We will not send out boards less than 11.75x18.75 inches.
1/8th inch / 3mm although there is variation between 2.6mm - 3.4mm due to manufacturing process leading to some variation. We recommend a focus height of 3mm. But calipers can be used for exact thickness.
Both sides are masked to prevent scratches damage during shipping. It is laser safe. However, the masking sometimes does not adhere well to the acrylic. Paper masking that that is not adhered can be a fire hazard. The masking is not necessary on the top face to prevent scorching, so we actually recommend cutting without the top masking but leaving the bottom masking in place.
We purchase the material in 4x8 foot sheets then cut down to size with a saw. Although we take precautions to avoid chipped edges and corners, this does sometimes occur. Because the acrylic is intended for laser use, we assume that the very edge is not used. These chips will not encroach more than 2mm and so should not affect the usable area. But if you are using the material for a project that requires perfectly smooth edges, please purchase the material and email us at firstname.lastname@example.org and let us know of your needs so we can select the pieces.
