    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...

    Children under six should be banned from stereoscopic technology such as 3D movies, computers and video games, says France’s health and safety agency, ANSES. It is also calling for children up to 13 to moderate their use of the technology.


    The call follows recommendations by the agency’s Italian counterpart last year and cites “pioneering analysis” of scientific research into the possible effect of 3D viewing on the developing visual system.


    So is its recommendation reasonable? Not if it’s based on existing evidence. Crucially, the agency’s report is unclear about what exactly this “pioneering analysis” is. However, what is clear is that there is no published research, new or old, showing evidence of adverse effects from watching 3D content other than the short-term discomfort that can be experienced by children and adults alike. Despite several years of people viewing 3D content, there are no reports of long-term adverse effects at any age. On that basis alone, it seems rash to recommend these age-related bans and restrictions.
