Apart from these, laser cut foam is also used for artistic applications, … These points indicate that workers involved with laser cutting of plastics may potentially be exposed to unacceptable levels of hazardous substances. This is the #1 material that causes laser fires. 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. Tags: Question 8 . You can cut this stuff and the universe will be safe if you cut thin pieces and watch closely. 4 0 obj See more on cut widths and Kerf (how much the laser takes away.) Hips has a tendency to heat up when being cut which can cause the sheet to melt and warp during the cutting process. Follow the manufacturer’s documentation for safe use of laser cutters.

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. comes mostly in thin sheets. Tags: ; but its really hard to say how much styrene is actually burning during the laser cutting process and if that translates into a hazard. that corrode the interior of the laser cutter. relatively poor choice of colours. Many plastics also give off ultra fine particles, plus carcinogenic polycyclic aromatic hydrocarbons. For metal based foams, a Fiber laser is most effective. For example, if cutting from 2mm Hips, it’s best not to allow anything less than 2mm in width. Safe 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". Make sure you leave lots of space between each component. The laser will be unfocused, won't cut properly and the material might catch fire. 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.

It creates harmful gases. Foam is used for suitcase inserts or padding, and for seals. We also ship internationally. Like PolyStyrene, it melts, catches fire, and the melted drops continue to burn and turn into rock-hard drips and pebbles. They say when burned, polystyrene emits styrene, carbon monoxide and other hydrocarbons. Drawbacks of laser cutting polystyrene. 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 Certain types of material should not be engraved or laser with a laser because of their chemical make-up. 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. Producing the same gasses that were used in gas chambers seems pretty darn dangerous and like there should be red flags up everywhere. Cut very poorly, ... it melts, and only thin pieces cut.

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. Laser processing these materials creates dangerous gases or dust. Register laser cutters on the appropriate groups’ BioRAFT equipment page. Polypropylene, polyethylene and polycarbonate all generate benzene, a carcinogen, during laser cutting. 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. Surfaces near cut edges discolor badly. Emits pure chlorine gas when cut! The laser cutter has the ability to accurately cut or etch numerous materials such as wood, paper, cork, and some kinds of plastics. endobj You can call our toll free number at 1-866-735-9255 and we can give you the tech-support number for DOW which manufactures Styrofoam. x��][o��~7��0��`�j�}=ص�� ���}���]_��ٜ����O'/���l�����gO7?�~���9۰�i�y����Gl�����޲�(憉��O�������Go��=����ذ=�;���=�O����w�U���eǺ��ݸ=��X�}�{"[���S�a�_�Ǐ��_ �������?
