Hey Guys, I'm building a plywood enclosure for my Prusa mk2s.

Hey Guys, I’m building a plywood enclosure for my Prusa mk2s. I plan on installing a fan for ventilation, But i don’t know what spot would be the best placement?

For example, On the bottom where the printer will sit? The back wall, the sides, or the roof? Not sure the best spot.

I will be only printing PLA for awhile, so i’ll need to vent heat out. But may want to print some ABS in the future.

Also, Do i want the fan to blow cool air in, or hot air out?

Not sure on ventilation at all obviously.

Any advice would be very much appreciated.

Personally you don’t want to run heat from the bottom because all it’s gonna do is hit that heated bed. You want to cool electronics so I would recommend on the back wall and aiming it at the board. If you are sticking with PLA for now, make the fronts plexiglass and removable and just leave the faces off for how so that the heat can bleed off. That’s what I’ve been doing with our lulzbots.

Thanks Griffin. In my current plan the front door will have a plexi window, however for taking it off, i wouldn’t want to do as the main reason i’m building an enclosure is to dampen sound as i live in an apartment.

Ahh. In that case have you checked out adding special feet for dampening?

The box i’m constructing is mostly for sound dampening, So i have it lined with Acoustic Board on all sides. I’m going to be using the Paver Stone idea as well inside the box. And i will also be using a rubber mat as well. I’m hoping with all of that combined i’ll have a near silent enclosure.

I fully admit i may be over-engineering it.

Saw somewhere (search YouTube, try here https://youtu.be/OnfYA5QLA84 ) about placing the printer on a concrete/cement tile. It helped a lot reducing noise.

Ventilation+ABS=bad. Ventilation+hotend_nozzle=bad. Ventilation after printing completions would not ne so bad.

@Nelis_Willers ​ I guess G+ apps are annoying the bleep out of you with “can’t post” bullcrap too. You multi-posted.

You could probably exclusively cool your electronics and motors with corrugated tubing and a cage fan and some encluosures.
