I know a lot of people are concerned about the fumes produced by melted plastics. As I understand it, many people "prefer" the fumes of PLA over ABS. I say "prefer" because it really is a choice about which is less offensive since both are not exactly pleasant fumes, unless you are into that sort of thing. While you will be able to use both PLA and ABS with the printer (simply adjust the settings from ABS to PLA), some people simply cannot deal with the fumes because it makes them sick or just because they don't like it. This is especially true for this project as its intended use is in the classroom where parents may not appreciate having their child exposed to fumes and the potential chemical burn-off associated with melting plastic. So, in an effort to make this project as kid-friendly (especially for people who may want to build this printer as a family project/ science fair project/ class project) I have come up with some ideas how to minimize exposure.
- Place the unit near an opened window (if there is no cross breeze, a fan directed at the window may help with circulation)
- Choose a printer option with a case and affix some piping to the back to lead out a window. (this will probably be an extra option)
- Print in a garage or a room that is not being used (I chose my bedroom with the door closed)
