I’m very interested in replacing my A1 with an H2D, mainly because I want to print some of the more sturdy filaments. However, I have a question about the filtering and VOCs with the H2D. Can you print ABS, ASA, etc. with a stock H2D and still be in the same room with? If you have an H2D, do you notice a smell when printing? Have you measured the VOCs in the air?
My understanding is that the “Smoke Purifier” add on would filter all these things out and allow you to print any material without breathing in harmful things. However, that unit is $600 and I’m not planning on doing any laser cutting (at least not yet) so I wouldn’t want to spend that much if I don’t have to.
Based on what I’ve read, the H2D filtration system works well for high-temperature filaments like ABS, though some users have reported a very slight odor. Additionally, the system isn’t a completely sealed solution. For optimal VOC removal, it may be best to place the 3D printer in a sealed cabinet or resin enclosure with a small exhaust fan that vents outside, to handle any VOCs that might escape the printer.
The smoke purifier won’t run when printing material that uses chamber heat. The vent is closed and the chamber fan recirculates when chamber heating is active.
While I haven’t printed ABS yet, I anticipate that the new filter system will remove a a large majority of the gases produced. I’m not sure if that will be good enough.
I’ve never been able to measure a rise in VOCs from 3D printing.
Venting H2D like the X1C/P1S is only going to work with PLA/PTEG and other lower temp filaments.
Ah, that’s right the enclosed Bambu printers recirculate instead of venting when printing VOC filaments. Hmmm… I wonder if a BentoBox would be enough to keep the particulates down. Or possibly a completely separate air purifier, like a LEVOIT Core 300-P.
I guess I’m not looking for a perfect system, just one that I can use in my basement office that doesn’t stink up the whole house and make it so I can’t even be in the same room as the printer. Right now, I can print PLA on my A1 without too much bother but PETG is a bit much.
The H2D likely has better filtration than the X/P with a bento box. The H2D is better sealed.
A typical room air purifier is good for micro particles that ABS in particular apparently releases. It does nothing for the styrene released by ABS. The interior charcoal filter should help a lot with that VOC.
A small window fan that can provide some negative pressure to the printer room is likely helpful.
There were true 100% corn based PLA back in around 2010, but they are very hard to work with. Over time, virgin polymer and other additives were added into the formula for better print result. All modern 3D printer filaments outgas toxic particles, level of toxicity varies.
The built-in filters offer minimum protection. For that reason, most of large studios don’t allow 3D printers be used in the office. They have to be in a separated room with industrial filtration system.
The best practice for home use is to put the printer in an enclosure and vent the air out side of the house. Ideally, use carbon filter before venting out.
I’ve found that the device seems to have a good seal. Not a perfect seal, but a good one. Printing with ABS leaves a much smaller smell than my old P1S. PLA is almost very hard to notice with just the stock filter.
The Air Purifier works for PLA and TPU, but not for stuff like ABS. I have my H2D in a closet with a door that has small gaps, and I really have noticed a huge difference.
I printed ABS for the first time today on my H2D. Previously printed on an X1C in a grow tent vented to outside my house which obviously takes care of the stink.
How did H2D do? Very well.
The initial purging which results in “poops” being dropped out the chute in the back DOES produce unpleasant smell. However, the actual printing did not produce any additional smell. It seems the machine is sealed very well and the activated carbon filter recirculation does a very good job. I also have a VOC meter next to my printer and it detected the increase VOC after initial purging but it did not go up during the print.
Does anyone know how to (if possible) turn on the recirculating filter while printing PLA? I find the PLA smell to be unpleasant and understand that there is a perfectly good filter in there but the controls seem to be bundled with “heating” so I can’t turn it on on the screen.
Ok, you guys are making it very hard to resist getting an H2D.
This is pretty good news and it would be great if you could keep an eye on the VOCs in the future to see how well it filters them out. Again, I’m not really expecting it to be perfect, but I don’t really have anywhere else to print and venting to the outside is not easy for me. So, a printer that can (mostly) take care of these things is much more valuable to me. If a simple addition (BentoBox?) can upgrade this easily, all the better.
Typical room air purifiers have carbon pellets too. At least the ones worth looking into. I run 4 air purifiers in my home and they all have filters just like the one Bambu put in the H2D, just different sizes of course. They’re very effective at cleaning VOC’s according to the 2 meters I have.
I’m also wondering this, I find the PLA odor pretty strong since the filter is bypass during PLA prints. Might have to throw a bento in there but that’s kinda dumb when they tout their filter being so great yet not being used while printing PLA
