Baltic Birch Plywood, 3 mm 1/8 x 12 x 12 Inch Craft Wood, Box of 2 B/BB Grade Baltic Birch Sheets, Perfect for Laser, CNC Cutting and Wood Burning, by Woodpeckers

I bought the 100 pack 2 times now for laser engraving. 1st pack all was perfect. 2ed pack was a little warped and had some marks but was not end of the world. Cleaned up easy and used hold downs.

Beautiful light colored wood. It's a nice light natural wood. It cuts and engraves beautifully. It's sturdy and durable. I highly recommend it.

Good quality. Product is as described. Have ordered 1/8" plywood from here before and would not hesitate to do so again.

The wood is very nice, and for the most part works very well in my laser engraver. BUT. On several sheets, I've hit spots that the laser couldn't cut through, or, if it did, it needed as many as five passes - using the same power and speed settings that cut through the rest of the sheet in a single pass. I'm not sure what's causing this, but it seems like the beam is hitting something in the middle layer that's flaring up, but preventing the beam from penetrating all the way to the bottom layer. Usually this is only a few small spots per sheet (there might be more, but if there are, they're in places I wasn't trying to cut through.)

Thank you !
