The laser is not designed to cut food, and people cut things that create poisonous/noxious substances such as wood smoke and acrylic smoke. Use rubber made for laser cutting that contain no chlorine. Contains a lot of glue so avoid fumes. Best and most popular plastic used for lasercutting. Gets a white "textured" look when etched. Also known by the tradename Plexiglass, acrylic is another very popular material for laser cutting. This article is one of a series of TWI frequently asked questions (FAQs).. Click here to see our latest technical engineering podcasts on YouTube. With laser processing, you can change the color pigments to achieve anything from a subtle whitening effect to dark brown shades depending on the paper and laser settings. Make has a How-To for identifying unknown plastics with a simple process. Make sure it's held down. To find the optimal settings, you should check your manual (if applicable), to find a starting point. Great for gears! Flimsy but great for testing and prototyping. Your email address will not be published. Difficult because of the vertical strips. The materials that can be cut by a laser cutting machine including metal matrix composites, leather, wood and fiber. Laser cutting is a process that uses a laser to cut different materials for both industrial and more artistic applications, such as etching. Higher energy and power consumption 5. 100% power, 50% speed or less works well for etching. Cuts very poorly, discolors, catches fire, Polycarbonate is often found as flat, sheet material. Plastic Acrylic Cast Black 2025.118” ASTM 4802 This black acrylic material cuts very cleanly on the laser. Other factors that impact consistent cutting. So check and double-check what you're cutting. Cutting ABS plastic emits hydrogen cyanide, which is unsafe at any concentration. Not using the optimal settings could lead to charred or bent edges. Common laser cutters that hobbyists use cannot cut metal, but you can send your files to a laser cutting service. Releases fumes and could catch fire. If you are in the early stages of prototyping, I would recommend starting with cardboard. Metal hardening 4. Additio… Thingiverse is a universe of things. Three passes at 80% power, 7% speed, and it will be slightly connected still at the bottom from the vertical strips. Let us know in the comments below! ). Typically can be set from 0 to 100% (maximum power). Check this article for the next steps on how to quickly find the optimal settings. This is a rigid plastic material with a premium looking high gloss finish. The laser can cut or etch. Polycarbonate is slightly bendable in most thicknesses under 1 inch. However, the material being cut and its properties often limits the suitability of some cutting mechanisms, assist gases, and laser types. Cardboard is cheap, easy to cut and easy to come by. Glass (etch, no cut) and epoxy resin (fumes). Woods that are oily/resinous are more likely to catch fire. Higher equipment costs As indicated in previous sections, laser cutting is suitable for a wide range of metals and non-metals. However, for different materials, due to their different thermophysical properties and different absorption rates of laser light, different laser cutting adaptability is exhibited. Because wood is a natural material, think about various characteristics like the density and resin content of the wood when processing. Stronger than acrylic, but not easy to use. The problem with foam is that it melts easily and can catch fire, so it must always be watched. Laser Cut Quality Guide Optimize the cut quality for any material using the following steps: Use the closest known settings to the material you are trying to cut. We frequently modify ABS enclosures that are .125 thick and we cut thin gauge ( .060) fire retardant on a regular basis. ABS does not cut well in a laser cutter. Laser Materials Guide ABS , cuts cleanly both films & sheet up to .250 (1/4″) in gauge. Emits dangerous cyanide gas and melts. Commonly used to make model aircrafts and other toys. Test to find the optimal speed and power settings. Download files and build them with your 3D printer, laser cutter, or CNC. Cutting metals with fiber lasers of up to 50 watts and without auxiliary process gases is a multi-stage process. Inconsistent production rate 3. I wouldn’t recommend it for later stages of prototyping or a final product, however. Your email address will not be published. Etching can be done on almost anything, wood, cardboard, aluminum, stainless steel, plastic, marble, stone, tile, and glass. Delrin comes in a number of shore strengths (hardness) and the harder Delrin tends to work better. Cuts extremely well leaving a beautifully polished edge. Don't ever cut this material as it will ruin the optics, causes the metal of the machine to corrode as chlorine is released and ruins the motion control system. Veneers have similar properties of the wood it's made from. It is thought that the molybdenum sulfate in the dry lube breaks down to molybdenum which either oxidizes or reacts with the underlying surface to create the mark. Our lasers can be used in lace-making. Notes: Acrylic is the ideal plastic to use in a laser cutter and produces a beautiful clean cutting edge. Speed & Power. Every material reacts differently under a laser and you should be prepared. It is highly rewarding as long as you are protected from the possible hazards. Vynil type plastics are especially dangerous because they release fumes that are known to make people faint. It's safe to 3D print but not to laser cut. Knowing what to expect will ensure your safety while laser cutting. Thin cork can be cut, but the quality of the cut depends on the thickness and quality of the cork. High power is used for cutting thick materials and lower power is used for engraving and cutting of thin materials such as paper. Acrylic is an ideal material to be cut on the CO2 laser. Home Services. Laser cutting is the process of precisely cutting or engraving a material using focused high-powered laser beam, directed by CNC (Computer Numerically Controlled) machine from a CAD vector file. Plywood is stronger than cardboard and it is still easy to cut, but it’s not as cheap or easy to find. Engraves well, cuts poorly. Copyright © All rights reserved. Notify me of follow-up comments by email. It also does not engrave well (again, tends to melt). Green seems to work best...looks sandblasted. Must have a good air filter system becuase teflon is toxic. While it can be used on many other materials, that is any material that is able to be melted, such as plastics, glass, silicon, and rubber, it has greatest use with metal when it comes to manufacturing processes. Hard to find good power setting. How does it work? There are two main types of lasers used in cutting, CO2 lasers and neodymium (Nd) and neodymium yttrium-aluminium-garnet (Nd-YAG). Engineered cork has a lot of glue in it, and may not cut as well. Serious Note: Never laser cut anything without doing extensive research on the material first, as some materials (especially plastics) can release harmful gasses. Yet acrylic - which looks, smells, feels and tastes just like Lexan - cuts smoothly and cleanly and is one of the best materials to use with the laser! Foam core gets burned and eaten away compared to the top and bottom hard paper shell. It does tend to discolor when cut on the laser. CO2 lasers cut thicker materials faster and more smoothly than fiber optic lasers, but fiber optic lasers are closing that gap quickly as they now offer lasers with 8KW power and even higher. ME 677: Laser Material Processing Instructor: Ramesh Singh Cutting • Laser cutting is able to cut faster and with a higher quality then competing processes: – Punch, plasma, abrasive waterjet, ultrasonic, oxyflame, sawing and milling • Can be automated • 80% industrial lasers in Japan are used for metal cutting 7 Services Material Guide Learn. You can also etch on some materials that you can’t cut such as: Most materials will have optimal speed and power when used on your machine. All of the materials that you can laser cut can be laser etched or engraved. Some people have had some luck using dry moly lube spray to the same effect. prepages.pmd 9/25/03, ... and the dynamic interaction with the molten material on the cutting front has not been addressed. Avoid cutting thicker cork (5mm). They direct the laser beamgenerated on a small zone of the material. Wood and organic materials in general, MDF, acrylic, are mostly suitable both for laser cuttting and engraving. The range of suitable materials 2.
