Polypropylene has a low melting point and have a tendency to heat up when being cut which can cause the sheet to warp during the cutting process. ... Do you have to wear safety glasses while operating the laser cutter? A laser cutter is a cutting device which focuses a high energy laser beam onto a material resulting in a high quality and dimensionally accurate cut. These devices can be used to cut, etch, engrave, or drill a variety of materials. Subscribe to our newsletter to receive the latest news and events from TWI: Polypropylene, polyethylene and polycarbonate all generate benzene, a carcinogen, during laser cutting. ii. <> The cutting and marking of polystyrene (PS) with CO 2 laser systems is characterised by its high precision and flexibility. The laser cutter has the ability to accurately cut or etch numerous materials such as wood, paper, cork, and some kinds of plastics. Apart from these, laser cut foam is also used for artistic applications, … It catches fire quickly, burns rapidly, it melts, and only thin pieces cut. Emits pure chlorine gas when cut! Polymers vaporize quickly when cut with a laser beam, resulting in smooth edges with minimal heat affected zone. The rule is that low-power CO2 lasers cannot cut or engrave Metals...!!! Laser cutting of polystyrene can be performed with a 9.3 or 10.6 micron CO 2 laser, resulting a clean, smooth, slightly melted cut edge, free of discoloration. ABS Emits cyanide gas and tends to melt ABS does not cut well in a laser cutter. Skin, Eyes and Lung Irritation Exposure to polystyrene dust as a result of cutting Styrofoam can result in skin, eye and lung irritation. The hazards associated with a laser cutter include the possibility of fires and the generation of hazardous and/or irritating combustion products. Certain types of material should not be engraved or laser with a laser because of their chemical make-up. For examples of materials I love to use, check out my list of favorite things, including materials and some places to buy them! ii. Use the air assist feature and verify it is working properly when cutting. ... Keep the laser cutting grid area clutter free by cleaning frequently. It can poison you, cause a fire, or damage the laser system; If a material you want to cut isn’t listed on the approved list below, please consult with a Peer Mentor and have an MSDS sheet ready for the Peer Mentor to look at. Drawbacks of laser cutting polystyrene. PolyStyrene Foam or PolyPropylene Foam (not to be confused with EVA foam, which is laser safe) I hope this information about what is and isn’t safe to laser is helpful! Cut very poorly, ... it melts, and only thin pieces cut. Follow the manufacturer’s documentation for safe use of laser cutters. <>>> The Fiber laser can cut through thin sheets of foam (up to 1/8” or 3 mm). ... Laser Cutting. %PDF-1.5 Keep in mind when you read the Material Safety Data Sheets (MSDS) for the foam you look up that they often are referring to possible safety hazards when manufacturing foam, not cutting it. stream 3 0 obj Polyethylene – Laser cutting of PE foils. SURVEY . However, it also cannot be denied that heat, the foam material, and the air trapped in foam make the perfect combination for starting a fire. <> These points indicate that workers involved with laser cutting of plastics may potentially be exposed to unacceptable levels of hazardous substances. Foams made of polyester (PES), polyethylene (PE) or polyurethane (PUR) are well suited for laser cutting, laser engraving and laser marking. It tends to melt rather than vaporize, and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid. Many plastics also give off ultra fine particles, plus carcinogenic polycyclic aromatic hydrocarbons. For this reason, it is recommended that these materials are not welded above their recommended weld temperature and that a good standard of local exhaust ventilation should be used. Polystyrene Cutting Example Marking Example Name Also Known As Type Laser Wavelength General Cut Quality General Mark Quality Barcode Mark Successful Safety Polystyrene Thermoplastic 10.6 µm nFair-good: Moderate melt & residue nFair-good: Engrave marks with some melt-back nNo endobj B Many wowoods 1/4" Avoid oily/resinous woods relatively poor choice of colours. :���V*�5b�R�q���O7�)�5�M��5em3����(R2�AW����=�N��X���p����;&�*� ?�懳ݰ��~���|̶� ��� ��S���`��o���S�}��2�����AZs��H�Q�>j(�?���n�����?�G��ED������]o�4{�j�g�R $�4�.q�7�O}�~��Q��a~�>�;�F4�fAu�>ȏz���U51��LJyh�N��th�s������3�)Y���t����G�ۿ�19[���I Polystyrene releases styrene, while PVC emits hydrogen chloride. ABS, HDPE, polystyrene and polypropylene, and anything with poor thermal properties is going to ignite rather than cut cleanly. However, there may be a health risk where the welding takes place in confined spaces in which the welder's head is close to the welding operation, and where ventilation is restricted. Laser Coding. not suitable for engraving. Due to contactless laser cutting, the PE foils will not be damaged. Yes. Producing the same gasses that were used in gas chambers seems pretty darn dangerous and like there should be red flags up everywhere. The laser doesn't work on polystyrene. Exposure to fumes given off during the hot gas welding of plastics such as PVC, nylon, PMMA, polycarbonate and polypropylene is not normally likely to give cause for concern. Register laser cutters on the appropriate groups’ BioRAFT equipment page. When the DMS evaluates whether a material is suitable for use in our lasers, we typically look at four factors: WARNING: Because many plastics are dangerous to cut, it is important to know what kind you are planning to use. The laser will be unfocused, won't cut properly and the material might catch fire. endobj For an efficient production, eurolaser offers numerous system sizes and options for laser cutting of foils and thin plates. “melty” raised edge if you’re not careful. The laser cutter high powered laser can cause damage to eyes and skin, and it must be contained within the cutter. This is the #1 material that causes laser fires. Ceramic based foam is not usually cut with a laser because it is very brittle and can crack. The copper wire test would identify ePVC as a problem. Hips has a tendency to heat up when being cut which can cause the sheet to melt and warp during the cutting process. While these machines can be of a reasonably high wattage and cut many materials with ease, most metals cannot be cut by the laser machines offered for sale here! See more on cut widths and Kerf (how much the laser takes away.) Safe Materials The materials that the laser can cut, are materials like wood, paper, cork, and some kinds of plastics.

Many plastics also give off ultra fine particles, plus carcinogenic polycyclic aromatic hydrocarbons. i. What is confusing about this is that polyurethane is generally considered a very "laser friendly" material to cut (stated all over the place on laser hobbyist and professional websites under acceptable materials). Of greater concern is exposure to hazardous fumes during hot gas welding of fluoropolymers such as PVDF, ECTFE, PFA and FEP, which can cause influenza-like symptoms known as "polymer fume fever". Polystyrene releases styrene, while PVC emits hydrogen chloride. It … Polycarbonate is a poor choice for laser cutting. Home. A fire safety plan will go a long way, but you can avoid ruining your laser cutter by being aware of what materials frequently catch fire.
