Instead of sawing those blocks, you can just buy activated carbon pellets in filter bags from aquarium stores that are way cheaper and around longer than these blocks.
I'm SO glad I found your channel! I just bought a Mars 2 and never have I heard this mentioned in ANY of the hundreds of videos I've seen. I haven't used mine yet but will do this! Thank you God bless you
FINally! ive been researching this for like 3 hours now because i found it weird when i first heard it. and nobody talks about this. best channel, honestly.
If you’ve never used an air filter these are great. ru-vid.comUgkx_dppjvjF8BYEmPSDTcgCUdRsgWYLXNHN I ended up with three after starting out with one. The noise level depends on the 1-3 settings with how hard you want the machine to work. You can also upgrade the filters and get one better for pet hair and smells which is a must have in my home. I noticed the air seemed lighter and easier to breathe when running the machine for the first time. Works great every time. Highly recommended!
Firstly, thanks for taking the time and effort to put this video together, well done. Now on a mechanical side of things. I have a new Mars 2 Pro, so the filter is new but there is still a smell, so after investigation I am developing the new module described below (at time of this comment). * The filter fan and the carbon block housing are not sealed, the fan just inserts into a cavity in the top of the housing . As a result, when the fan starts a back pressure is created against the filter block resulting in contaminated air being pushed out past the fan body into the machine cavity, as well as thru the filter, as the fan is screwed tight to the bottom of the table the contaminated air cannot be recycled and is forced out the rear vent holes. Hence you will always have some bad air being delivered to the atmosphere and you lungs. * For effective airflow to occur you must have free flowing air at the inlet and outlet, with the main cover on and fitted with the seal the filter fan must struggle to get inlet air flow as the work cavity is almost a sealed volume and it is a small fan. Also, the fan pushes the air onto the filter, it needs to be in a draw thru configuration as this creates less turbulence and better air flow. * The idea of the small stand alone internal filter device that Elegoo market is on the write track but doesn't go far enough. There is a solution to this, maybe not the only one, I plan to remove the entire filter pack and fan, re-use the fan and filter core, rehouse them in a new unit that will sit inside the protective cover, thus recirculating the contaminated air infinitely. No external smelly exhaust to upset the neighbours. I will be using the existing fan and filter, as it is new, but it will be replaced with a 100mm filter block as described in the video. The new design will take a 100mm high block. The activated filter block shown in the video will produce 4 replacement filters (50x50x100mm) that should last for 2-3 years dependant on usage. NB: The masks that many brands supply with their printers are next to useless as they are NOT activated carbon based but merely a particulate mask, good ventilation and the correct breathing mask are a must . Side notes 1/ My filter block was only 60mm high. 2/ I saw a Elegoo youtube which showed a 0.07A 12V fan, mine is 0.1A 50x50x10mm 3/ When I removed the Elegoo filter box I found a series of 2.5mm holes widely spaced thru the bottom, this will have the effect of greatly reducing the airflow to a negligible amount. 4/ Test results...Preliminary results show an marked increase in airflow, the UV cover is installed WITH the supplied gasket. I have also installed in the new housing a square of thin micro fibre to catch any carbon particles from the reclaimed block as I chipped some of the edges removing it, unavoidable. Smell test - with the unit installed and the printers cover fitted with the gasket I could not detect any smell at all, the only time there was is when the printer cover is removed, but that is expected. Summary and Link I am very happy with the results so far and when the old filter block wears out I will replace it with 1 of the 100mm high blocks that I now have in my stock.

May I suggest a better, possibly cheaper and much longer lasting solution? I have invested in a 'Carbon Air Fan Filter' with an ultra silent duct vent + some flexible tubing and hose for my work area. Initial investment is a bit larger than those small carbon filters included with some 3D printers/air scrubbers - BUT the filter lasts up to 2 years (Rhino Pro), and 9-12 months for the hobby version - and that's running 24/7. I haven't compared to the small ones, but the large filter solution seems much more efficient to me. I use it when soldering, but it also cleans my room of any other smell (cooking, etc.) The great thing about having a circulating filter inside my shop means I don't have to vent to the outside, and heat the room up. Before getting the filter installed the vent would completely drain the room of heat within hours. When depleted it is possible to get replacement pellets, though it would require some handy work to get the filter opened/closed - and get costs even lower in the long run ;ø)
I also buy it as granular little pelltess for fishtank filters. Very easy to change. Fo the mini filters I use a 3D printed cage that fits into the mini-devices.
You could also fit the bin-extractor mod inside, I've seen mod kits to fit an extractor fan where the carbon tower fits. You do have to bore a hole in the back of the housing for a hose to come through but then you only have to deal with the hose itself and not a big bin, and of course you can watch your print progress unobstructed.
Seems like we should just make a duct that goes through the case "sealed" to a external filter... make print a new backside to the case to avoid permanently modifying the case which might not void the warranty...?
@@Keep-Making can't find it anymore, they was no commentary on how to do it, they just ripped out the old one and place a new in one. Never explained which one to replace it with
I don't think this fan design is suitable for that. The problem is static pressure, or lack thereof, as the fan is designed more for low-impedance airflow than for pressure needed to traverse obstacles. When the airflow impedance is too high, the fan stops pushing air, there can even be a tiny reverse airflow instead. This sort of filter lattice is very open for the air to pass through; this isn't the case with pellets. Maybe if you used only a small layer of pellets, much smaller than the size of the block, that might just work. Another trick that might just work is to print a set of vanes, essentially such a lattice, to be attached to the fan and sit above the pellets, this can linearize the fan exhaust airflow and prevent turbulence from forming an air plug. I'd say these are directions worth experimenting in, if so inclined. Someone else has demonstrated printable attachments that look almost like a set of fan blades but stationary and differently shaped that also provide airflow to static pressure conversion, but the specific engineering behind them eludes me.
Thanks for the video! Am I seeing that basically there is no active fan pulling/pushing in the air through the filter? I mean it looks like it just sitting there with a vent in and out into the bottom of the casing? What the heck?
I am awaiting my Mars 2 Pro so thank you for this video. I purchased a larger room air purifier and have the elegoo purifiers on order (delayed until March) so i hope with it all it should be enough. Some also had indicated you could purchase filters some use for aquariums and the like
Is this still a problem with the mars 3 and the mars 4? i am looking to buy a printer for miniatures for around 150-250$ and would prefer if it didnt kill me
Appreciate the intent of this video but that filter setup isn’t sensible. Unless there is inflow of air the fan won’t draw to exhaust fumes. It seems much more reasonable to remove that filter unit and take advantage of the vent holes to connect to an exhaust hose such as used for tool dust collection. Just vent it outside using standard fittings.
Would it be a bad idea to just disconnect the filter/filter fan entirely? I have a venting setup already from my original mars and honestly it's just such a hassle to do this every few months if my current setup will work. Only thing is I don't want the fan just spewing chemicals into the rest of the machine
FYI it's probably worth inserting brass threaded inserts into the screw holes for the holder and go to M3x7mm button head screws. Then you can more or less take it apart as much as you'd like.
Carbon filters are good at filtering out bad smells but not good at filtering out actual harmful gases. They're no going to filter out enough of the VOC's to make enough of a difference. And one of those tiny filters especially is going to do bugger all. You need a ventilated room with air running in and out. Even then you should be wearing an A2 mask at all times.
Like someone below mentioned I would just duct the fumes to the outdoors. I might have to design a duct fitting to do this. Don't want to cut a hole in the cover, so I would have to design another cover so as not to void warranty.
Another great video. Replaceable filters that are not changed are so often silent killers, both of machines and people. Of course it often occurs because of extortionate prices that put people off. Hope your efforts are rewarded with plenty of sales!
There is an easy answer to this... you take a plastic kitchen waste bin, and a bathroom extractor fan kit. Cut a hole in the bottom of the bin, fit the fan, fit the hose to the fan, drop the hose out of the most convenient window, set up your print and then put the bin over the printer. It will draw all that resin vapor off and leave it outside. yes it takes another socket to run the fan, and its a little noisier, but you're not breathing crap.
The next step is to design a cartridge that people can print that is easier to remove. I also like the idea I saw in the comments of using carbon pellets instead. So maybe make a removable cartridge/basket for pellets too.
Slight difference between the fumes from a laser cutter (have a 40 and a 60 watt Co2 Epilogs) the nature of literally burning materials is a ton more hazardous. Most of the resins I use are VOC free anyway. Uber click bait title.
Same. It doesn't help that it feels like 50% of the info out there is stuff like "You're gonna die if you're even in the same country as your printer when it's running!!" and the other 50% is like "Idk I cuddle with my running 3d printer when I sleep every night and I've never had a problem"
@@Keep-Making I would agree saying, that it lowers the amount of VOCs, but not that it is able to catch it all. For example carbon activated filters in industrial tobacco pipes are able to get rid of 80-90% of the bad chemicals in smoke. Same thing we have with filters like you show. They will not catch alle the bad stuff out of the air that resin is able to contaminate. As only the tiniest amount of these VOCs is pretty health related you definitely should not take a filter like this as a no brainer. Even if you use filters like these, wear a filter mask to protect yourself. There is a reason why industrial workers in the chemical industry always wear masks, even if they have very big air purifiers to lower the initial concentration of their fumes. I don’t want you to get me wrong. But don’t let people think things like these will solve a problem and it does not. At the end, they risk their health cause it isn’t a save way to go.
i don't have a mars 2 or even a risen printer but the video was soo fleuwed in explaining if found myself at min 9:15 without knowing . a really good job you did there 10/10.
thanks for this vid I’ve been doing research for my mars 2 pro that’s arriving in two days and wanted to be as prepared as possible, are you sure the disassembly for carbon swap won’t possibly affect the way the printer works?
Keep in mind the screws he loosened may change the level of the machine. It makes sense to re level the build plate after opening the case and flexing it as he did
Sorry for the off-topic comment. I'm choosing timing over context, as I just saw that Blender 3.0 is now out of beta and officially launched. Is there any chance of an update to the setup and add-on video guide for the new version?
So, basically these "air quality" filters the manufacturers are worried more about appearances and profit margins than effectively protecting our health.
The cure for this issue is DO NOT BUY the Elegoo Mars 2 pro... Any company that would sell something this flawed should not be in business in the first place. They care nothing for their customers or their customers health, only for their profits.
