The cutting and marking of polystyrene (PS) with CO 2 laser systems is characterised by its high precision and flexibility. 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. The laser cutter has the ability to accurately cut or etch numerous materials such as wood, paper, cork, and some kinds of plastics. iii. <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 9 0 R] /MediaBox[ 0 0 612.18 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Home. It catches fire quickly, burns rapidly, it melts, and only thin pieces cut. The versatility of laser cutters is remarkable, considering they can cut, mark and etch. Polystyrene releases styrene, while PVC emits hydrogen chloride. Safe Materials The materials that the laser can cut, are materials like wood, paper, cork, and some kinds of plastics. No. The hazards associated with a laser cutter include the possibility of fires and the generation of hazardous and/or irritating combustion products. iv. For example, if cutting from 2mm Hips, it’s best not to allow anything less than 2mm in width. ۉFx�׻'���;�鍕�u~@3,�@w�Qn���됎��s� ����e��W탧�����>��RY�(�>��0��W���9H@f!�j�Í��T���ϹEADd�8oO��mچ����ٛm��S��a����Ђ6XԳ�wM�7�� � ��Yz����ѻ?j��`��7� B.֬�?��� ��?n�$�h�i ucՔ��]�4�:�V��d���.o�/ౕ�㍴8ze�Q� ��{���&P7��o��8��/m�qh���۫_셍#06�V �� ?���|��7�4���ɤ�4���1��%��fיPN̙BCa� Ą��ȋm�*y���K3��)� ޘ��p�T����nWr. 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! 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. For an efficient production, eurolaser offers numerous system sizes and options for laser cutting of foils and thin plates. <>>> Polystyrene foam Catches fire This is the #1 cause of laser fires! It creates harmful gases. 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! The risk of fire is too high. Styrene on its own is considered a hazardous chemical. 2 0 obj The EPA says its "a suspected toxin" to the respiratory system etc. Another fluoropolymer that can cause polymer fume fever when overheated is PTFE, which is used as a non-stick coating for hot plates that are used for welding other thermoplastics. Hips has a tendency to heat up when being cut which can cause the sheet to melt and warp during the cutting process. ... Do you have to wear safety glasses while operating the laser cutter? ... Laser Cutting. 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. comes mostly in thin sheets. ABS Emits cyanide gas and tends to melt ABS does not cut well in a laser cutter. Laser technology produces heat in a highly controlled manner because of how quickly it moves across the foam material. 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. These points indicate that workers involved with laser cutting of plastics may potentially be exposed to unacceptable levels of hazardous substances. 5mm is a safe distance. 4 0 obj In addition, the filters that are commonly used to clean up the fumes that originate from laser cutting of metals will not remove the fumes produced from plastics. ii. They say when burned, polystyrene emits styrene, carbon monoxide and other hydrocarbons. 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.
