I will get a little bit out of topic here.
We are building a stand for our Ultimaker 2 at office, mostly to keep it safe from dust, since here that is a serious issue.
My doubt is about the need of ventilation during the printing process. We designed a case that is about 600mm by 530mm by 530mm (h/w/d) made out of acrylic and plywood. The idea is to always keep the printer inside it, even while printing. Do I need to provide any ventilation system for when its printing? I didn't want to keep any ventilation slits because of the dust, but I worry that the heating of the printer might be an issue.
I don't think you need any ventilation if you have less than 10 printers. 10 printers printing PLA non-stop will make less aromatic hydrocarbons than frying one hamburger every 3 hours. That's an estimate. ABS is much worse but even ABS is not too bad. I think you should try it first and decide later if you really think it needs venting or filtering. I suspect you will conclude it's fine without even if the printers are used non-stop. Let us know (how big is the space anyway?).
