Always put the filter on the intake side of a fan. That way the air will be filtered before entering the fan (=good), and the fan is better at pulling air from something, than trying to blow it through something. So you will most likely get a higher airflow and better filtering try my filter solution i posted in my Chanel
You do not want the fan to be pushing the air out of the hose either. The fan should not be attached to the printer but to the window or where you are venting air out to. If the enclosure is air tight apart from the intakes where fresh air is being drawn from then you will get more out of your fan or blower motor this way.
I'm very interested in your Prusa XL enclosure, but hopefully you can provide support for my ventilation preference. I currently use dual 40mm Noctua fans, along with 40mm ducting, to exhaust my Printed Solid MK4 enclosure directly out a window - no filters. I did the math, and the PS enclosure has slots at the bottom that add up to the same area of the dual 40mm exhaust ports at the top. This creates a perfectly balanced air flow without drafts that is perfect for PLA and PETG. I also turn off the fans for printing nylon, which allows the enclosure to warm up nicely but not overheat, as any excess heat rises and escapes via the exhaust ports. Dual 40mm airflow is sufficient to completely exhaust all fumes, can't even smell ABS, even at input shaper speeds. I know I can print an adapter for using 40mm fans, but the point here is balancing intake and exhaust area, and having intake at the bottom and exhaust at the top. While the XL is bigger, I feel that dual 40's are still ideal.
@@madebyjwillis Thanks, I saw that update, and understand the reasoning, but my impression is that's essentially the opposite of what I'm describing. You have dual 40mm intakes at the top, plus it seems like you're leaving the extra vent holes beside them operational. I only want ducted exhaust at the top, and equivalent area intake at the very bottom, working along with natural convection currents, and all other openings closed. If done correctly, the air can still flow past the idle heads, helping regulate their temps. But it's still an enclosure, and temps will rise, hopefully around 40c for printing nylon, so Prusa will have to figure out the idle heads temp regulation issue. Your attempts to cool the heads are making this a no go for me. Admittedly, I'm not up to date on the idle heads temp issue, so maybe it's way worse than I'm imagining.
No there won’t be - we’ve used printers in enclosures for years and never had a problem. I think the PSU overheating is way overblown, so if you’re worried about that, you should purchase a different enclosure
@@JohnOlson oh yeah more than enough - the standard build (without a lot to accessories) is around 500g total so even if you print a decent amount of accessory prints, you should be good to go. Use .20mm layer height and 15% infill (default settings basically)

Yeah I made an adapter for a 40mm fan that fits between the aluminum extrusions at the back of the XL - checkout some of the earlier SUMO updates

@@PaulStevensonPinball hmmm interesting - thanks for your input
Hepa filter will do nothing for organic vapors.
Will there be a way to add an intake fan near the PSU? I am concerned about my MK4s PSU overheating during use.

Will Delack be available soon? Are the printed files on Printables pretty final at this point?
Should be available by next week - we’ll be sending an email update tonight. Files on Printables are final!
@@madebyjwillis Thanks! Looking forward to the email then. Do you think 1kg is enough to print all the parts?
Nevermind.. its listed on your assembly page. LOL

@@madebyjwillis 2 or 3 walls, and 4/5 top/bottom enough? Going to print mine with ASA since my MK4 is ASA parts.
Noctua fan more like hoctua fan 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
