    Is 3d dangerous good for kids?

    i saw some article that stated some(or may be all) 3d printer is dangerous to kids especially the FDM one because they use heat to melt the filament which oxidize the toxic out of the plastic.

    Some plastics are more toxic than others. PLA is low on the toxicity scale, although it may emit hormone-mimicking nano-particles when heated. ABS is worse, though. SLS printers melt particles of plastic or metal with lasers, so they require positive ventilation as well. Other types of printers have problems of their own - the photo-reactive resins used in SLA or DLP printers aren't something you want in your kid's mouth or on their skin, while powder-bed printers (like the Z-corp machines) use proprietary powders and binders of unknown composition, so it's hard to say how toxic they might be, although no powder is good to breathe. Probably the safest type are the LOM printers, like the Mcor Iris, which use regular paper as a feedstock, laminate them with glue and print on them with inkjet inks. They aren't cheap, though...

    3d printed objects are safer for kids over the age 3, depending upon the material used and construction of the object. The process of 3d printing has many potential risks, but one product especially, Cube is suitable for kids over 8.

    The heating pan is dangerous for kids as well. If you put your hands in the darn hot thing. Of course, if printer is cheap, it's probably made of cheap and not very high-grade parts.

    I agree with @Harley, never leave young kids alone with a 3D printer. By all means, 3D printers are not any toys. So, must be handled with caution.

    Hidden dangers of 3D printing

    3D printers also emit ultrafine particles that are impossible to see with the naked eye. Although small in size, these particulates are particularly harmful because of their ability to get permanently stuck in the human respiratory tract. Additionally, small particulates have a larger total surface area that creates an increased physical exposure risk between body surfaces and hazardous particulate surfaces.

    It can be dangerous if they touch the extruder or if the room is too small because of some material are not good for the health.

    I agree with you, 3D printers are not for kids, it is not good for them. Nice information.

    Parents should notify their child about the probable dangers; do not abandon them unwatched, and use precautions (gloves, glasses, etc.) when handling a 3D printer.

    It's dangerous for children. We need to keep this kind of equipment in a locked room or outside the house.
