How to stay in good health using a 3D printer

    Good day to all. Today I wanted to touch on a very sensitive topic, which manufacturers of printers (even I) and consumables prefer not to raise. All users of desktop 3D printers are aware of the basic precautions (at least I hope so), but just in case:

    1) Before leaving the printer to work alone, make sure that the first layer has laid down well and nothing is sticking. It's no secret that printing success by more than half depends on the first layer.

    2) Make sure that the coil with plastic does not wound, and will quietly unwind from the bobbin. (I had one time when I couldn’t achieve an even supply of plastic because of the eternal distortions of the reel, I threw the thread through the curtain rod and left the bobbin on the floor. So the bobbin successfully wound onto the table, and the printer successfully lifted itself and hung in the air when I came into the room. (I was lucky because I was at home)

    3) No need to check with your hands (any parts of yourbody) whether the surface is heated. I do not advise touching anything at all. because even the carriage, can press a finger very cool. (And if it’s also a central carriage with a heating surface, it won’t seem a little when she presses her hand against one of the walls of the printer and presses it with a heated hot end). Ksati, gloves are also not a panacea, they are wound only on the road. Check everything through the readings of the printer.

    4) I hope you do not need to write about age, and all caring parents understand that this toy is for a child who is already at a conscious age.

    5) Print only in a well-ventilated area. In particular, ABS plastic.

    Today I want to talk about the last point. I missed some roofing felts, or I didn’t really see the manufacturers spread this information much. Of course, there are closed printers in which there is a special filtering system (I saw only one such one, and its price tag was 400 rubles) Just a closed camera will not help in anything, unless there is an exhaust hood that will remove all the air from the camera to the street.

    And now, after today I accidentally stumbled upon an article on a wiki about ABS plastic, where it is not recommended to use ABS plastic in 3D printers in black and white. Here is an excerpt from the article.

    “The real danger that ABS plastic can pose to humans can occur in several cases:
    Heating (acrylonitrile pairs are formed) of the material during production (casting, extrusion). Closed special boxes with powerful hoods and remote process control are needed. Therefore, it is much safer to refrain from using ABS plastic in the manufacture of prototypes using 3D printing technology. It is best to use a safer PLA plastic (polylactide) for this purpose. “

    I have a question. How dangerous is the use of ABS plastic in 3D printers at home. Please answer me this question. I think many will be interested to read about it. Please argue your answers in the comments.
