Engraving Blank Materials ABS Double Color Plastic Sheet, Black/White (7" x 11" x .040", 12 Pieces) for Interior Signs, Badges.

This engraving plastic works as well in my laser as any other I have tried. It comes with a plastic protective film on top. You want to leave that film on when you cut and then carefully remove it afterwards as it will keep your material from getting all sooted up. Raster engraving will not leave a smooth surface. I've tried the stuff from Trotec laser and I didn't get a smooth raster finish with that either. What does work is cutting, and it's cousin - vector engraving (which is just cutting, but with less power and faster so it doesn't go through). The top coat on engraving plastic is REAL thin, so you'll likely find that the fastest movement and the lowest power your laser will do will be enough to leave marks. THE MOST IMPORT THING IS SAFETY!! I run a Middle School makerspace. The most important part of onboard training (Which i do for each and every tool in the space, for each and every student that comes in) is how to work with a tool safely. Lasers work by cutting things with heat, so a risk with laser cutting is always FIRE. I've had fires start when cutting cardboard, paper, foamcore, and rubber. You should ALWAYS have a fire extinguisher next to your laser cutter. You should always check before you start cutting that you know where said extinguisher is. You should NEVER leave the laser while it's running. Watch it work! Also, you might keep a spray bottle full of water near the laser. Most laser fires can be extinguished with a few swirts of water and that's a lot easier to clean up than a fire extinguisher. You will need the following upgrades on your laser to use this material: 1) FUME EXHAUST: Folks, having an exhaust to take your fumes outside is super important no matter what you are cutting in the laser. Cutting WOOD in the laser results in ultrafine (<2.5pm) particles that are hazardous to your health. This stuff is ABS plastic, read up on burning ABS - it will release formaldehyde which is REAALLY bad for you! Don't skimp out, get a fume exhaust system in place. 2) Air assist: ABS is known to be a fire-prone material when laser cutting. Having an air assist is really important for blowing out most fires that will start when cutting this material. Again, don't cheap out, an air assist costs less than a new laser cutter or house.

i have a engraving sideline ,getting material was a problem

First of all, laser cutting ABS does not produce Chlorine gas like burning PCV does. So never cut PVC with a laser. That being said, burning ABS can produce hydrogen cyanide gas. How much? Difficult to say, but hydrogen cyanide gas is produced by burning many things, including cigarettes. Lasering wood also produces many toxic compounds. So no matter what you engrave or cut on a laser good ventilation and avoiding inhaling any of the fumes is necessary. Now to this particular material. Finding the right setting for your laser may take some significant trial and error. I have a Boss 1630 105W CO2 laser and ran at least 30 combinations of speed, power, air and painters tape before getting so reasonable results. The pictures are from a 6 inch wide placard I made. From 12 inches away the engraving is smooth and clean. If examined closely, you can see ridges in the cut from the laser scanning. The settings I settled on are 400 mm/sec at 35% power for the fill and 35 mm/sec at 60% power for the outline cut. Air was on and the surface was covered with painters tape to prevent smoke staining around the edges of the engraving and cut. I tried leaving the top film on instead of the painters tape but the result were not as good. The engraving was done at 300lpi. Lower lpi increased the ridges in the engraving. My only real complaint is that the "white" bottom layer is not very white - more of a grey.

Don’t waste your money, this material is garbage. I have used many two color plastics before with my laser, but for some reason, this material does not provide the expected results. I actually used 6 sheets in this pack, just testing all my settings, trying to pinpoint exactly what would be the best setting to use. After four sheets, I actually took my entire laser apart, thinking that maybe something was misaligned. 2 hours later, got it all back together, realized there was nothing wrong with the laser, and that it was definitely the material. Total waste. No matter what I did, every engraving would come out with a gray hue inside the (what was supposed to be white engraved area), DEFINITELY not white. I have a 40W CO2 machine, and it works perfectly fine with other 2 colored material (TroLase). It would be really helpful if the company provided at least some sort of a “starting point” for what settings they recommend for the material, but they definitely don’t. The company website is no help at all. Like I said, save your money. I should have read some of these other reviews before I purchased.

Good stuff for cnc machine

My first disclaimer is an apology for this being a little long. My second disclaimer is that I am a novice laser user, and I am still learning applications on both the Glowforge and CO2 laser machines. I lean heavily on reviews when I am purchasing items that I am not that familiar with or I'm looking at purchasing something totally new for the first time. Because the reviews were so conflicting, I wanted to see if I could help the person like me who may be looking at this product. It is possible to cut/engrave on this material with a Glowforge or CO2 laser machine. Like with all things in life, there is a learning curve and here is what I learned. If you want a clean cut/engrave and you are using a Glowforge machine, you should remove the plastic film. When I attempted to cut/engrave without removing the film the plastic bubbled, warped, and was hard to remove. If you want a clean cut and you are using a CO2 machine, you should not remove the plastic film. When I attempted to cut/engrave without the plastic film, the charred areas turned white and the print and material looked old and badly worn. I even had to use multiple settings so I would not cut through the material when I was engraving words. Ultimately, I was able to produce a rather nice print on both machines. Most of the bad prints that were produced were from me not knowing the correct settings for my machine and not from the product. Now with that being said... the material was slightly warped after the cutting/engraving was completed on both machines. If you bend it a little and place it under something a little heavy, it will take out some of the warping, but it wasn't completely flat again. The white is 100% grey on the product that I received. I gave it three stars instead of the four that I wanted to give because of this reason. I was supposed to produce a black and white sign, and I produced a black and grey sign. For the naysayer, the grey was not that color because of the engraving. If you take a new sheet and place it beside any white material, the sheet is clearly light grey and not white. So, if you need a truly black and white sign, this product will not give you that finish. Also, the finish is not a glossy black. It is a matte finish, and it is very easy to leave fingerprints. After all of that... I would purchase the product again if I needed to make a quick sign and didn't need a true white. However, I probably would not attempt to sell it to anyone. I do plan to try some of the other colors to see if I get the same results.

Great Quality. Used to make Halloween earrings and they turned out great!

purchased to go with an engraver that doesn't work - but you can use manually. Husband reports it takes a few tries to get what you want - there is a film on the outside that you need to remove. Once you get that down, they work as they should. I never hesitate to update my review should new info seem useful.
