as someone who works with metal powder in an SLM 280 and an EOS M290 everyday, I can tell you that it doesnt matter HOW careful you are, you are going to need to clean powder off of thigns all of the time no matter what. Working with those machines, I would NEVER put a machnine that uses powder in a place connected to where I live.

@darrend7352 12 күн бұрын

Hi all, I've worked with SLM and fully agree with this comment. I've moved to work in a university now and run additive manufacturing courses. I can say the main difference between metal powders for SLM vs the polymer powders for SLS are mainly reduced risk of fires and explosion with polymer powders (it essentially is not combustible in the volumes present in polymers). HOWEVER, the risks to your respiratory system are not reduced. This process looks an absolute death trap at the moment, rooms should have constant ventilation generally as will as extractor hoods in local area to improve safety. The PPE should really be a full respirator at a minimum, not a paper mask only. The companies selling the machines are the only people showing less PPE, bias maybe? I personally know researchers in the space who have been in the additive powder process space since before health risks were known. These people are now on oxygen tanks to breath almost constantly with doctors giving them months and years worth of remaining life expectancy. Do not do this at home, it is not safe.

Thank you for mentioning the safety side of SLS printers as I always see promotional material where no one is wearing PPE. I Interned at a full scale SLS facility while in college and as long as anyone was working with the printers, the room had to be locked down. When working with the printers you were required to wear a full respirator hood, anti-static shoes, a chemical and flame retardant lab coat, and disposable gloves to be compliant with lab safety. Clean up also required a specialized anti-static shop vacuum and everything had to be cleaned before the room could be opened again.

Based on that I don’t think this technology is ready or safe for home or hobby use. Sure he used a mask and gloves but they aren’t perfect and it doesn’t stop the powder from getting in the air or on surfaces where it will later be dispersed into the air. The particles are that fine that they will probably stick around for a while in the air so just taking a mask off as soon as you are done likely is not anywhere near enough protection.

@leogoldschmidt1549 13 күн бұрын

@@conorstewart2214 I would agree with that statement. The reason resin printers can work in the home/hobby space despite also being dangerous is because spills can be contained and fumes can be extracted. You spill SLS powder and that stuff is airborne. even after settling, it can get kicked up again and stick to clothes. Hence why SLS powder is treated a lot like you would asbestos.

You will need a hepa filtered vacuum and not just hepa type filter it has to be a explosion resistant antistatic self contained absolute hepa filter (expensive) otherwise you could cause a powder explosion or just spread the dust around even more. The fume extractors for these are normally absolutely massive the in machine filter and dust filter they ship are just going to spread the dust around so you can't visually see it. You should also have a particle counter to make sure the exhaust, fresh air intake, filters, vacuum are all working properly.

Hello, I am an Additive Manufacturing Subject Matter Expert for the Department of Defense. It is astonishing how often safety, health, and wellbeing considerations are overlooked in the context of additive manufacturing products. As highlighted by others in this discussion, issues such as static discharge, electrical arcing, and fire hazards are significant concerns. These factors make the use of such technologies in a home environment highly inadvisable. It is important to note that engaging in these activities could lead to your home insurance policy being invalidated. For instance, at timestamp 12:10 in the shared video, the use of a non-explosion-proof vacuum cleaner is clearly demonstrated, posing a substantial risk. Moreover, a simple mask is insufficient for depowdering processes; typically, a controlled environment such as a glovebox is necessary. The particulate material involved behaves like tiny marbles, spreading ubiquitously and presenting further hazards. I could elaborate further, but the key takeaway is to ensure you thoroughly understand and mitigate the risks involved in additive manufacturing.

@rsilvers129 12 күн бұрын

I agree on the dangers but your insurance won’t be invalidated except for fraud such as arson. Any accidents, such as a home burning down, would still be covered if it was not intentional.

How come none of the videos I've seen on this show people wearing the right kind of PPE and have no proper work environment for it? A home is certainly not a place for SLS of any kind. The shoddy prototype transfer buckets really show how little thought for safety there is. That fan/filter combo is just a cute way to reassure you it's safe, but fine powders get everywhere and the whole area should be a managed zone, enclosed and with with airflow considerations. You will not see most of the dusts you inhale, that's why wash and change facilities are provided where these are worked with. The OSH guidelines for working with them are pretty strict on workplace exposure limits, even "inert" ones.

Fun fact: following an internal presentation, WWF printed a pamphlet saying scientists suggest that one might be consuming UP TO ABOUT 5g of plastic a week on average. The proverbial credit card. But the press reproduced it subtly but crucially wrong, "up to" kind of just disappeared. It was unclear for a while how the involved came up with this conclusion, but a paper by the same scientists came out a few months later. They took existing consumed particulate count estimates (confidence interval about 1-2 orders of magnitude, not great), and fitted various shapes to them up to 1mm in size (correctly but somewhat generously deciding that anything larger than that would no longer count as microplastics). The resulting estimate has a 7 order of magnitude confidence interval. At the top of it was the figure of 6.3g if memory serves, at the bottom a zero with many zeroes, and their estimate for highest-likelihood amount was 0.3g or was it 0.03g i forget, i can look it up for you if you really care. Not that it really matters with a confidence interval this loose, because these are effectively all slightly better than fantasy figures. I'm not saying 0.3g of plastic are healthy in microplastic form, and particulate count and area are likely more of a health hazard indication than bulk weight, and there is indication that we should be worried, but... please it's not 5g, that's absurd and very unhelpful and misleading.

One issue with SLS printers is that you can only re-use the material so much. So you have to throw out so much of the powder that enters the build chamber. This has a big impact on the economics of printing as a small part with tall geometry costs more than a larger part with shorter geometry. For small scale this tends to discourage prototyping, or one offs, and is more for predictable batch printing.

@hanelyp1 13 күн бұрын

How much of that could be addressed by sifting and grinding used powder?

@Anthromod 12 күн бұрын

@@hanelyp1 Not really as the issue is the high heat + oxygen chemically changing it. Basically the powder is heated to just below sintering temp and the laser pushes it over. I'm sure the suppliers over estimate the amount of powder you need to refresh, but for engineering parts you can't guarantee part properties with a low refresh rate. Powder near the printed parts also ages quicker so for dense builds it has more of an effect.

Filtered, outdoor extraction is really the only true safe way for these types of printers. Home printing is super cool, doesn't mean it's also super safe for your lungs / body.

@conorstewart2214 13 күн бұрын

@@jeb101 yeah filters aren’t perfect and they do need replaced over time. From what other people in the comments have said, when working with SLS professionally it is done in a sealed but outside ventilated and filtered room whilst wearing full respirators with flame resistant lab coats and anti static everything to prevent sparks and the room needs cleaned up before it is unsealed and they are allowed out. That isn’t something that is feasible with a hobbyist in their home. Now micronics have commented and said not to do it in your bedroom or living space and to do it in a garage but that doesn’t seem enough, especially considering how the powder will get everywhere and kicked up into the air later. I don’t think this is ready for home use. Edit: unlike FDM which is safe and releases no particles or gasses when not printing, resin is constantly releasing fumes unless put back into bottles and sealed, SLS may be similar with powder getting spread through the air and onto surfaces, without proper cleanup it may stay in the air for a while.

Hey Joel, thanks for checking out our printer! Sorry the bin broke in so many places during shipping - for the production machines, we plan on switching to Reaction Injection Molding (RIM) for the bin, or adding sheet metal inserts to reinforce the FDM print, which should make it much more durable. Regarding the safety aspects, you should definitely wear a N95 respirator and gloves when handling the powder. However, it is worth mentioning that unlike metal powders, Nylon 12 is inert and non-toxic (though inhaling large quantities can still cause discomfort). The sift bin and dust extractor can keep you workspace pretty clean, but spills can still happen and of course, the sift bin can break. (also, we recommend placing the powder scoop on the build chamber BEFORE raising it up). We do NOT recommend setting this up in your bedroom or living/work space - instead, put it in your shop or garage - somewhere out of the way. For the brushing part, it is actually only necessary if you don't have a media blaster. If you have a media blaster, simply take the parts, break away the large chunks, and blast it directly. This make it much faster. Of course, we are planning to do another round of beta testing before the production machines - which is why we are stating a delivery time of 8-12 months after launch. Other creators have also experienced some manufacturing related tolerancing issues that are causing print issues, and we do plan on working with our sheet metal and CNC shop on dialling them in. Let us know if guys have any other questions!

Some additional refining of the product to allow multiple air filters or some other method of moving the part from the powder without directly transferring the material post print would be ideal.

Really nice to see what they are working on! I will be curious in the future to get one in house, but not from Kickstarter. I find fascinating how you can easily swap polymers without need to do a crazy amount of cleaning in the machine. I'm running for quite some time SLS production and even with all the right tools still a messy process. To be honest I think if they will have a better post-processing unit even if that mean pay 5k for it, it could be really worth it for the workflow but most importantly the safety of people. Highly recommend having a dedicated space, powder will be everywhere, even with industrial equipment you still find it on top of any surface. As well, SLS powders are not themselves explosive, but there is a risk of explosion when they are mixed with air, so highly suggested a static dissipative industrial vacuum to clean the spills of powder. Looking forward to seeing what they will do in the next 12-24 months.

This is a really cool technology. Also special thanks to you and the commenters for mentioning that working with these requires respiratory protection to prevent inadvertently breathing in the dusts. I am not sure that I like the way they do the "fan" thing tho. I think it might be better if they included a "plastic tent vent hood" for you to place the cake in ... and have the fan attached to it so that it always pulls air out of the tent, and prevents you from accidentally getting particles in your "environment" (Which clearly happens as you shake the container). If they include a mobile vent hood, it would not add too much to the cost, since it would essentially be low cost probably clear plastic and maybe some structural pieces and it would likely improve the safety, as long as it was properly filtered and vented.

@riakata 5 күн бұрын

You have the right idea the dust processing should be done in a hood with all three sides covered the mfg solution is to reuse the glass to cover the top which isn't enough and the thin fan body is extremely risky as the airflow can be easily disrupted and blow back on the dust hazard.

See the major problem with this """Desktop""" SLS printer is that you need a whole workshop to use it too. Something they very avidly avoided mentioning in their videos showing the printer off. Yeah you can fit it on a desk where you would put your computers and stuff if all you were doing is sitting it there as it prints, but you need a dedicated table to do all the things, a dedicated sandblowing box thing, etc. It's really not a desktop SLS printer because of this. If I wanted a desktop 3d printer, I'd get either a resin printer which needs only 3 small machines. The resin printer itself, a washing bin, and a UV spinning stand, and you could fit all that on a table with ease. But honestly my biggest issue is that they are marketing this as a "cheap" "affordable" and "very easy to use" SLS printer, when it very much is not.

I am not too sure you should compare Micronics with Bambu Lab. Bambu Lab pushed out an excellent polished product that is easy to use for the masses but on a fairly established technology. Micronics’ product is far from easy to use or seem polished in anyway. Clearly SLS technology is not anywhere near as established as FDM filament is at the moment. It is messier than the resin printing process; but the final finished part could have the potential to be phenomenal. It seems to me that Micronics just want to make this printer functional while keeping it low cost. I don’t think ease of use is even high on their priority list at the moment. This is the opposite of what Bambu Lab is trying to do. So comparing the two is like comparing apples and oranges.

I like some of the features of SLS (integrated support, fine resolution, etc), but there are aspects that make it less desirable compared to FDM. 1) cost: powder is expensive and it can only be used so many times during print 2) materials: it currently is inherently single-material and single colour 3) cleanup: it's messy, and time consuming, and there is some danger of inhaling particles (which can't be good). I think FDM will eventually rival all of SLS's benefits and there are good examples of many, though they have yet to all be integrated. SLS still offers quality and layer uniformity that can't be matched by FDM currently, making this useful for specific applications, and certain enthusiasts.

Pro tip for your sensor buddy. Use deep sleep on an ESP32 and you don't need the distance between the micro and the sensor as there will be no heat buildup. With an ESP32 you can get the entire sensor smaller then the PCB of your micro controller. With ESPhome you don't even bother with firmware. Just configure it in .yaml and you are done.

You're missing the other huge danger of the nylon powder: it becoming air borne as a dust and then catching fire from an ignition source. It then doesn't just burn, but it will detonate like fine sugar, flour, or any other powdered substance that can be oxidized or burned. A room that has its air if filled with the dust is an explosion waiting to happen and any ignition source can set it off. Proper ventilation with a filter on the intake of the ventilation, is needed when working with powders like this. You also need to clean up any spills promptly and regularly clean off fallen dust from surfaces in the room to prevent buildup since the dust being knocked airborne off a surface is just creating another explosion danger. This is why no company has made an SLS printer for the home. They are worried about the dust. Now, this is no more dangerous than aluminum metal powder, but that stuff is still really dangerous and should be treated with respect and not just allowed to get everywhere when you use it.

@riakata 12 күн бұрын

The miconics mfg is claiming the powder is safe in small quantities which is a very dumb statement of course a small amount of toxic powder is relatively safe but it ignores what happens in the worst case if someone drops the cake or spills a bottle on the ground now what do they do. Some might reach for a home vacuum and literally cause an explosion. The mfg is spreading dangerous misinformation about the safety hazards in an attempt to sell more printers. Done correctly you can print sls at home but it is nothing like resin or fdm PPE requirements you need a lot of specialized equipment to do it right.
