Hepa filter for 3d printing

Why you won’t find a HEPA filter hanging on the back of our enclosures – Printed Solid

First we should talk about 3D printer enclosure designs and why you may want one. Enclosures serve three main purposes. 1) It helps keep heat in and prevent drafts over your build volume. 2) It keeps pets and hands away from hot ends and beds and pinch points. 3) It can help control VOC’s (volatile organic compounds)

• Keeping the heat in is what most people think of when they think of enclosing a 3D printer. This can be a factor to some degree but too much heat is also a problem for a lot of materials and printers. There are lots of designs for 3D printers which try to completely seal in a printer and insulate it and people try to add heating elements to make it even hotter inside. If you look at your printer it most likely have some or even a lot of plastic parts to it. Even if you have an all metal printer you might still have plastic fans, wire components, belts and so forth. Plastic gets weaker as it gets warmer, long before it gets to the melting point. So if your printer has any mechanical or structural components in it made of plastic then they can wear out or fail if it gets too warm inside a completely sealed enclosure. So heat is a friend and an enemy at the same time. Another problem with too much heat is that most extruders have a passive fan cooling the heat sync part. So if that gets too warm then you face heat creep and your extruder jams. So our enclosures have intentional openings on them to allow excess heat to escape while still preventing drafts over the build plate. It’s a delicate balance of retaining heat and releasing heat. A great example is a competitor out there completely seals up a Ultimaker printer top completely. Then as a user prints higher temp materials for a long time the plastic clips on the gantry soften and then entire XY axis drops out of the printer. Causing damage that if you weren’t watching it would be extremely expensive to repair. We have seen Prusa printers completely melt inside a hot box and even Raise3D recommends removing their hood while printing PLA so you don’t get heat creep on your extruder and it jams. So a little heat is ok but a lot is bad.
• Keeping pets and little fingers out of the printer. It’s a minor concern but one to think about none the less. Your cat will like the warmth of the heated bed and may even think it’s a moving toy to swipe at. With the hot parts and moving parts it could hurt your curious pets if they go snooping around. The same is true for kids. However with kids it has an additional factor. At home or in school people will bring kids right up to the machine so they can see the magic of 3D printing. As close range a tiny hand sticks out at touches the hot end and now you have a crying child to deal with.
• Volatile Organic Compounds. Even the words sound scary. There have been lots and lots of studies about it so we don’t have to go into the fine science of the issue. One thing that is not mentioned and is commonly misunderstood is VOC’s and HEPA. So lets get some simple numbers out there. HEPA ratings matter but you would be surprised by how much they don’t matter. Confused? That is the way they want it. Basically a 99.97% HEPA filter will capture a .3 micrometer particle, also called a h24 class filter. At the low end you have a 85% HEPA filter which is 85% or E10 rating. At the extreme high end you get into ULPA filters up to 99.9999% or U17 rating. OK, I said I would keep it simple and I haven’t, so I’m sorry for that. Let me try again and simplify these numbers even more for you. Most HEPA filter options are from 85% to 99.97% and capture particles down to .3 micrometers. The closer to 99.97% you get then the fewer amount of those particles get through the filter. You will rarely find a higher filter rating above 99.97% that won’t cost less than a car and require almost monthly replacement but those filters get you down to .1 micrometer particle sizes.

A quick summary: Most HEPA filters capture around .3 micrometer particle sizes and the better quality ones let fewer .3 micrometer particles get through.

Now to quickly shorten up all of those research papers for you about VOC’s and 3D printing.

• The particle size of the emissions from a 3D printer are between .1 and .3 micrometers.
• The amount varies depending on what material you print with.
• Most HEPA only filters will only capture the largest of these particles.
• An open window or well ventilated room will drop the levels below safety standards.

What about those particles smaller than .3 micrometers?

Well you can get one of those filters that cost as much as a car every month or you can used activated carbon. Activated carbon comes in many flavors and some of the facts can be misleading but to simplify it I will keep the scope limited. Basically the size of the activated carbon matters, smaller the size of the carbon the better. Then the amount of activated carbon matters. More is better. Activated carbon works using adsorption. No that is not a misspelling, I said adsorption which is different than absorption. Basically activated Carbon holds those VOC’s to its surface. So the size of the activated carbon matters because the smaller it is then the more surface area it has and the more VOC’s it can trap. Then there is the amount. Small amounts trap less than large amounts. The worse activated carbon filters out there are the woven mat filters like you find on a fish tank filter. They weigh nothing and are usually a plastic or cloth mesh covered in a thin coat of activated carbon and you can see light pass right through it. So even if they captured every particle passing through them then it would fully adsorption all of the VOC’s in a week or two.

Finally! Why we don’t put a small HEPA filter hanging off the back of our enclosures.

Those tiny fans with “HEPA” filters hanging off the back of some enclosures or printers do almost nothing and even less after a week of being on. It’s great marketing for sure and that is it. They barely move enough air to pull VOC’s through the filter. A total build volume of a printer is around 2 cubic feet. The recommended exchange rate at that size would 30 CFM after the filter. So those tiny filters that say 30 CFM fans are saying the fan moves 30 CFM but after the filter that number can drop to under 5 CFM. So not only do those small filter not capture enough particles, wear out in a week or two but they don’t even move enough air to actually move the particles through the filter to be captured.

Another issue is that a one way filter like those negate the entire purpose for an enclosure. The filaments with the highest particle emission’s like ABS, Polycarb, Nylon are the ones that need a warm enclosure. So if you are filtering air out of your printer then where is the new air coming from to fill the void? You’re not creating a vacuum so air is coming into the printer from somewhere. Cold air from outside the printer is being drawn into the printer and creating cold drafts across the print area and creating warping and de-lamination of your prints. Or worse those small filters are pulling cold air from gaps near the filter and not your print area and not capturing any particles, making you believe you are being safe and actually not filtering anything.

This is why we teamed up with BOFA and their line of filters. With the Print Pro 3 you get a true 88 CFM after the filter rating and a 3 stage filter with a pre-filter to capture 5 micrometer particles, then a true 99.997% HEPA filter and over 4 lbs of activated carbon to capture the .3 micrometer particles and VOC’s instead of just an ounce or two on the other solutions. On top of that it also has a supply and return hose to get the heated air back into the chamber without creating cold drafts over your print area. Then to top it off it has a warning indicator to tell you when to replace the filter. We searched high and low and found the BOFA units to be the only solution out there in this price range. While the science is still out on how the VOC’s might affect users over long time exposure, we don’t want to offer a solution that is just a placebo. We wanted a solution that actually addressed the issue. Since most consumer’s don’t have a way to test for VOC’s and UFP’s to find out if a filter is actually working we want to make sure the ones we sell actually do it.

Review

This air purifier is one for the long term. It does everything you need it to do plus a lot more as you can see in the features. Other than the wide range of positives that this machine has, the big downside is the price of the filter. Sometimes you just have to pay for quality because LEVOIT has plenty of it.

Many users have used this and been pleasantly surprised with its results. At first, air purifiers may seem like they don’t do much, but a high quality one really makes the difference.

One user described how he has a neighbor who constantly chain-smokes day and night and it drove him mad. Not only that, but he had kids who were breathing all the contaminated air which isn’t an ideal situation.

After purchasing a LEVOIT LV-h233 machine, their problems were cleared up so much better. Simply running it on high for 10-20 minutes totally cleared the smell and it’s no louder than a white noise machine. They also moved to a dusty, dry desert area which was also fixed with this air purifier.

If you have a filament or resin 3D printer, this air purifier should significantly reduce the fumes and provide you with cleaner air.

It looks professional, well-packaged and has made a massive change to many people around the world.

Review

It covers 465 sq. ft. area for cleaning which is more than enough for most rooms in a house.

3D printers set in that room size will benefit by cleaning the air thoroughly, much more so than not having an air purifier at all. This is definitely a machine that shouldn’t be taken lightly in terms of its ability to get rid of bad odors and transform your air quality to something very ideal.

This machine has a genuine A+ pre-filter which is the first level of filtration for those larger particles that we can see, like dog hairs, lint and dust. These should be replaced every 3 months or so.

We then have certified true HEPA filters which capture the commonly-known 99.7% of microscopic allergens floating in the air. For the best performance, you should replace this filter every 12 months.

It is equipped with cooling modes such as germ, allergen and a turbo mode which does a great job tackling the levels of air pollution you require.

It doesn’t have a remote control like some other air purifiers, but that isn’t a necessary feature. The Honeywell HP300 is a good product to have if you are looking for a serious product.

Review

If you are looking for an air purifier for small space even for homes to get protection from polluted air quality then you are looking for the right product.

It can be used for purifying air polluted from your 3D printer. Although we can’t see these small particle, they are definitely being put out in the air and we don’t have the best ways of getting rid of it. The LEVOIT Core 300 does a great job filtering these tiny particles.

Its smaller size and lightness add easiness to portability. It would be an amazing addition to a small office or home. This is pretty much quiet. On average, it uses just 35 watts of power and that is not bad for any user.

There may be reports or you may see this in comments that it gets warm after operating for months, but it is quite simple to release this concern by turning it off and keeping windows open for some time.

You should go for this product if you are on a budget because it is quite a new product and there would not be any issue to recommend it for small places air purification.

Alveo3D, a filter kit for safe 3D printing at home and in the office

August 20, 2020

Alveo3D is a young French company that has developed a nanoparticle filtering system for 3D printers. Its goal is to reduce toxic emissions from machines by reducing the risk of air pollution when they operate in poorly ventilated environments. Ultimately, these particles can be hazardous to the health of users. These small filters are installed in small boxes, also developed by the startup. The whole system is made of plastic elements printed on a 3D printer. They are now available as kits or ready to use with boxes that can be customized to fit the size of the 3D printer. We caught up with Lucas Martini, CEO of Alveo3D, to learn more about these solutions. nine0007

3DN: Could you introduce yourself and your relationship with 3D printing?

My name is Lukas and I represent Flexee System, the company behind the Alveo3D project, which addresses the issue of toxic emissions from 3D printers. We are the three partners behind this project, which started back in 2018. Victor is an industrial product designer and Laurent is a team developer. 3D printing has become an important tool in our arsenal for prototyping our models and demonstrators. nine0007

3DN: Why did you create Alveo3D?

We quickly started using 3D printers in small spaces like our workshop or home. We have become aware of the potential hazard associated with our machines due to throat and eye irritation and the unpleasant smell of melted plastic. We know of some manufacturers that have mentioned the same symptoms, especially when using thermoplastics such as ABS or HIPS. Some reported headaches, and the symptoms were more severe in smaller, less ventilated spaces. The same descriptions were found on the forums, with some members suggesting homemade filter solutions. nine0007

During 3D printing, we can actually encounter two types of harmful emissions: toxic emissions associated with volatile organic compounds (VOCs) and nanoparticles. That's all it took to convince us to equip our 3D printer with a filter system. Speaking a little about toxic emissions, it is important to point out that this is a long-term risk with potential chronic consequences. Pollutant emissions enter the air in low concentrations, and the regular presence of a 3D printer can be harmful. When 3D printers are used in poorly ventilated areas, the accumulation of nanoparticles and VOCs can pose a risk of air pollution. nine0007

The risk associated with volatile organic compounds is well known to industry and air quality authorities. Some gases emitted by thermoplastics are known to be carcinogenic. Even in PLA, which is naturally based, the amount of additives added to it makes it toxic. Other filaments, such as POM, naturally release formaldehyde and there is a risk of inhaling toxic air when opening a bag from a spool. For nanoparticles, the risk is less well defined, but probably even more dangerous. They can be found in the body, organs and brain and are difficult to eliminate by the human body. nine0007

CNRS recommends using a HEPA filter for nanoparticles and activated carbon for VOCs. We searched for existing filtering solutions and were surprised to find that there were few 3D printing solutions available for less than 150 euros. Many manufacturers create their own air filtration systems that they place on the body of their printer to draw air in and filter it before it enters the room.

The first version of our filtration system was made by hand. HEPA filter, granular activated carbon and 3D model to fit everything on our printer body. The results were encouraging, but we wanted to make sure we were dealing effectively with all the toxic emissions. What should have been a simple accessory for our 3D printer turned out to be a real piece of work. We then mapped the risks associated with most of the gases we could detect during printing. We synthesized the results of studies on the release of nanoparticles and realized that the processing of these elements of the order of several tens of nanometers would require further development. nine0007

Over the course of 3-4 months, we tested dozens of filter configurations on our test machine. We have worked with European and Chinese manufacturers to find the right combination for capturing VOCs and nanoparticles. We wanted our work to remain accessible to all users, because the danger is no different from an entry-level machine or a professional model.

3DN: How do Alveo3D air filters work?

Alveo3D filter blocks have been designed for 3D printing, for easy use and easy replacement of filter cartridges. They combine a powerful high pressure fan and a filter cartridge specifically designed to combat harmful emissions from FDM 3D printing. This filtration system includes an activated carbon bed that allows it to handle a wide range of VOCs.

We are often asked about the life cycle of our filters, but the answer depends on many factors, the main ones being printing time, filament type and extrusion temperature. As a precaution, we recommend 600 hours of use. This is mainly due to activated charcoal. When it is saturated, it will let all the VOCs through, so it is important to change the filter regularly until saturation is reached. 600 hours of filtration is approximately one change every 6 months for printers that operate occasionally and every 3 months for printers that operate regularly. nine0007

Our filtration systems are mounted on the 3D printer body. It's an essential tool to protect your equipment and print successfully, especially with some plastics that are harder to print like ABS. It also reduces the noise level of the machine. First of all, it allows you to capture all the vapors even after the plastic has cooled down. In fact, we have 3 goals: to maintain a stable ambient temperature, to limit the negative effects of deformation, and to process the air in general. We produce custom boxes according to the dimensions of each printer. Conventional design with aluminum frame and plexiglass or polycarbonate fronts. The boxes are equipped with our filtration system and we can add options according to the specific needs of our customers. nine0007

Finally, as I said, all the plastic parts of our boxes are 3D printed, allowing us to make continuous technical improvements as well as customize the final solution. They are available as kits or ready to use.

Two models have now been developed. The alveoONE filtration model is used with a box equipped with an air intake that does not need to be closed. It draws air into the case, creating a small vacuum, and exhausts clean air. It is suitable for printing common thermoplastics, PLA, ABS, PET. The alveoONE-R filtration model is used with a waterproof housing and works with internal processing. If you require an ambient temperature above 40°C, this type of internal processing allows you to increase the temperature. nine0007

3DN: Do you think users are aware of the dangers of 3D printing?

We did a little research on this topic, and according to our results, half of the users are not aware of the risks. Both professionals and novices are aware of bad odor and irritation after a few uses. The adoption of security measures is not yet automatic. However, some of them believe that the use of PLA is enough to protect against toxic emissions. Although PLA is less harmful than other thermoplastics, it does contain additives to improve certain performance and technical properties. Therefore, it can be toxic. One of Alveo3D's mission is to provide information about security risks and best practices. nine0007

3DN: What are the future projects of Alveo3D?

We have several areas of development for the coming months. By the end of July we will be able to deliver our first V2 e-cards. They are used to monitor filter housings and monitor filter wear. We are also preparing a model specially designed for companies, alveoONE PRO. This will be a filtration system capable of handling the air of two printers at the same time, or a high volume printer with individually tested and certified filters. nine0007

3DN: A few words for our readers?

Basically we have a few more agreed projects for the future. But we must also monitor current demand and developments for 2020. You can find our various solutions on our website HERE.
