Ordinary mechanical engraving cannot engrave dots of different thicknesses in an economical way, so it does not have a grayscale representation. The laser engraving machine realizes engraving in the way of dots, and has natural advantages in grayscale performance. For this reason, the grayscale expression is used as much as possible in the engraving design. The advantage of this is that on the one hand, the coloring process is reduced and the cost is saved; When the user is using it, first fill the graphics with different grayscales (the text must be converted into graphics first), select the black and white mode for the engraving output, and try the effects of different dots. The accuracy is generally not more than 500dpi. Desktop laser engraving machines are now popular. Although they are small in size, they can basically meet people's engraving needs. The more popular brands are Sculpfun, Atomstack, Ortur, etc. More brands can be found on the HTPOW website.https://www.htpow.net/sculpfun
Wood: Log (unprocessed wood) wood is by far the most commonly used material for laser processing and is easy to engrave and cut. Each type of wood has its own characteristics, and some are denser, such as hardwood, and require higher laser power when engraving or cutting. We recommend researching the engraving properties of unfamiliar woods before engraving. Plywood Sometimes customers may ask you to engrave on plywood. In fact, it is not much different from engraving on wood, but it is necessary to pay attention that the engraving depth should not be too deep. The edge of the cut plywood will also be black like the wood, the key is to see what kind of wood the plywood is made of. Coloring: After wood engraving, there will generally be a burning feeling. It has an original artistic beauty when matched with the wood background color. The depth of the color mainly depends on the laser power and the engraving speed. But some woods are usually softer and you can't change the color anyway (eg: birch). Occasionally a client may ask you to color the finished product, using acrylic paint. Sculpfun S10 laser engraver can cut 15mm plywood, 20mm light wood, 10mm walnut and teak, and the cutting surface is very clean with the help of the air-assisted compressor, and it is not easy to carbonize.
Density veneer: Ordinary density veneer This type of MDF is the kind of wooden pallet that we often use as a sign liner. The material is high density board with thin wood grain on the surface. Lasers can engrave on such materials, but the engraved patterns are uneven and black, and generally need to be colored. Laser-specific density veneer This type of density board is specially designed for laser engraving. The engraved pattern has a uniform color and has a good effect without coloring. Cleaning: The MDF surface can be cleaned with a damp cloth after engraving. Filling: Acrylic paint or alkyd paint can be used. When engraving, the color of the graphics can be set to 60% grayscale, so that the bottom surface of the engraving is somewhat pitted to improve the adhesion of the color. The S10 laser engraving machine can cut 6mm MDF boards and even 15mm acrylic, making it a very powerful machine that can meet the basic production needs of small businesses.https://www.htpow.net/90w-scul....pfun-s9-laser-engrav
