Material that can be used in Clean room

Posted · Material that can be used in Clean room

Hi community,

Had a quick question, would anybody have an idea which material I can use in a Clean room manufacturing environment? I am not looking at printing inside the clean room, however the material needs to pass the tests to be used in a clean room.

Basically looking at material

1. To be less than 1E11 ohms (surface resistivity).

2. And performing outgassing test to ensure, there is no gas coming out while using it

Would love any help

    Concerning outgassing, it is not only the material itself. 3D-prints do contain lots of small holes and "channels". These voids may contain air, gasses from the plastic when it was still hot, glue, hair spray bottle gasses, alcohol from cleaning the glass plate, or water vapour from removing and washing the model, or water vapour from absorbing moisture from the air. If it is a vacuum clean room, these are going to come out too.

    So I don't think anyone could give valid official specs. If the model should not outgass, maybe you need to put it in vacuum for several days, prior to use? Not sure what this would do to the chemical structure (as some composites get destroyed when put in vacuum, if their chemical structure contains bonded water, and that is dislodged in the vacuum, for example glass ionomer cements).

    At least, FDM prints generally do not smell, so they probably do not outgass very much at atmospheric pressure. Other 3D-prints, made by lasers or UV-lamps solidifying a liquid resin, do smell very strong for months and months. This indicates that there is a substantial amount of uncured resin present, that is outgassing. I have some models that still smell very strong after two years, in UV-cured resin.
