3mm 1/8" x 12" x 20" B/BB Baltic Birch Plywood (60pcs) - Perfect for Arts & Crafts, School & DIY Projects, Drawing, Painting, Wood Engraving, Burning & Laser Projects - Cherokee Wood Products

Package well, good looking sheets of wood.

Excellent material for a laser cutter. (Be aware (!) slightly bowed so set the depth of your cutter in vicinity of where you will be cutting if you are cutting a small area. I haven't tried any process for making it flatter and I haven't tried cutting anything using the full size of the sheet.)Good buy for the larger boxes of sheets. Comes very well packed against water; cardboard box should be sufficient to protect the edges. A 40 sheet box weighs 19 pounds so just expect that before you go to pick up the box if you get a large one.

I read reviews of some warping of the boards. A lot are warped. When I first received the package they were nicely packaged in cellophane(?) and looked sturdy and I was happy that they didn't look warped. I noticed immediately when unpackaging that most of them are warped slightly. I did attempt to straighten a couple but it didn't work. I use these for laser projects. I am able to clamp them to my base and straighten them and they cut lovely so far. I am not unhappy with the product. Wood is still expensive in the big box stores so this package price is reasonable. The wood has kerf-it isn't exactly 12x12.

The plywood can laser cut a bit inconsistent. No big problem, just increase the power or decrease the speed for a consistent cut.

I'm about 1/3 the way through the box. All sheets have been dead flat, and the show side is flawless. I am using 5-6% power for raster engraving @ 100mm/s and vector engraving @ 20mm/s. For vector cutting, I bump the power up to 16% @ 8mm/s. It slices the wood like butter. No issues with any voids. Even the finest cuts come out perfect. Check out the almost paper thin mask strap on the ornament picture.FWIW, the National Park Service sign is free from ThingiVerse. The ornament design was $1 from Etsy.I rarely give a 5 star review for products. This one deserves it. I will be buying more.

Yes there is some warp, which is unavoidable (if you understand 1/8" plywood). However, the benefits far out way any issues. I used this on a CO2 laser. It rasters very nice since Baltic Birch plywood has 100% solid, birch core.While it is very strong wood, you can bend the plywood in the opposite direction of the warp to get it to lay flat for the laser.The board finish comes with a rough sand, so I fine sand the laser surface before lasering. With some trial and error with stains, sanding, repeat stain, etc., you can achieve some beautiful grains! I would include a photo but all I have is an award plaque that I can't share. I will continue to buy this product for the laser.

I’m very disappointed with this wood. It's extremely warped, making it nearly impossible to work with on my laser cutter. The warping prevents the laser from cutting all the way through, and even after trying to tack down the edges, it didn’t help. As a result, I’ve wasted a lot of wood. Given the price I paid, I expected much better quality. Would not recommend.

I've purchased several times previously without too much issue. Unfortunately, my most recent box has not been great so far. A lot of the wood has extensive voids and/or are warped and/or have patches. I'd say I've had to toss 1/3rd of what I've used so far - sometimes I can't tell until I cut it that it is crappy, which wastes time and material and puts wear/tear on my machine.My machine is kept in good condition and can go through materials twice as thick but it is struggling to cut this even on higher powers/slower speeds. Also, the warping is a fire hazard. Reminder to laser users to always watch your stuff and have equipment ready in case of a fire in your machine.I understand there are probably supply chain issues at work here, as the seller has previously provided fair quality for the money wood, but I can't recommend what I got in the last box for any laser users.Might be good for other things though! The shipping was quick and the boards are the correct size.
