same. @L00ww i whould rather not thrust 100% what a chinese company (due differents standard in safeness and hazard controll than USA or EU), say concerning "just a ventilated area". Take an extractor, if you do not have a room for the printing, like me, buy an enclosure capsule. take the filament one since the extra room are always welcome, and atleas one whit a room for fume extractor. Buy a fume extractor. For extra step, take into consideration to swap inside filter time to time. For extra step, buy two inside resin carbon filter (assuming there is space to put those inside the resin printer itself, aside for some particular combination of machine and active filters\heater there will be no printing quality issue). Take consideration in security first, then buy a printer. But to not succumb to fear or ignorance of something becouse is way better to pic up a 190% mark up already printed product.

NO STOP THIS. I am really happy that you are explaining the risks. It is something I warn people about, also spray priming models with out a mask, airbrushing. However it is important to explain the risk in a responsible way if people are going to do it. Telling people not to print at home is far to alarmist. When you sell the models to people it really does make you look pretty bad. No matter you pointing out how ironic that position is it really does not come across well. You dont need to do the BS click bate, it makes you look worse and untrusting. Please stop. Education is good in the hobby your better than this BS rubbish. Can I also point when talking about saftey. 11:23. You have an employee working in the lab in a ruddy T-shirt, Shorts, open toed sandles, you have bottles of chemical just lying on the floor in the background, you have wires and cables exposed on the ground which at best are trip hazards and you have wheely chair right next to the cables. That lab has more risks than you covered in this video.

[@sockylogic2014]

I was just about to point out the sandals and shorts. I also always wear a lab coat when I am working with my uncured resin/prints.

[@andrewramsdale]

Not defending the sandles and shorts but there in Ontario Canada there summers get into the high thirties Celsius witch is around 80 90 Fahrenheit plus humidity witch makes it feel hotter than it is so a lot of people where less clothing maybe they should say if you are working in the forge area bring a change of clothes and shoes

[@bahamutdragon1754]

@@andrewramsdale You missed the best part. That mask that employee is wearing is not designed to prevent resin fumes. Its just an empty cord with an open air outtake, you can see it if you pause at 11:32. Its not even an actual filter that he is wearing, that is a mask designed to push oxygen into low oxygen environments. The international standard for organic filters rated to stop resin fumes marks them as bright yellow. You'll notice there is no color band bands on the face mask.

I print at home. The resin printer is actually in my bedroom, but it's in a ventilated tent that goes out the window. I don't smell anything, my air quality meter doesn't even budge when I use it. Post curing/cleaning I do in my garage, which isn't fully sealed from the outside anyway. I don't wear a mask when Iremove prints but I do intentionally keep my head out of the tent with the fan still going, since why stick your face in it when you don't have to. I also transport the unwashed minis to the garage in a container so I don't accidentally drip somewhere. I think this video is a bit too harsh sounding. Resin isn't some insanely deadly chemical that if you are even around can make you sick or worse. When I was in the military I was the hazmat custodian for my squadron, I know what hyper dangerous chemicals are. Resin is a step above cleaning chemicals, not something like sulfuric acid that even the vapors of it can hurt you almost immediately. I'm not saying resin isn't dangerous, far from it. I'm just saying people have been making videos like this lately basically pegging it as something so dangerous we probably shouldn't even be allowed to buy it without special licesnes. That, it is not.

[@darthplageous5412]

I'm going to diagree here a little. I've also received various levels of hazmat training for various chemicals. And frankly this video isn't for us. We both have an understanding of how to properly deal with hazardous materials. This is more aimed at the average person who wouldn't know or think about these things. You also mention that you print in your bedroom, and that you have a tent that vents outside. That's fine for you, but for the average person that should probably be avoided if possible. For one because of your training you know how to correctly set it, and you also said you had an air quality sensor. A lot of people aren't going to necessarily know how to correctly set it up or test for leaks, and most people probably wouldn't think about getting an air quality sensor. Without one someone could accidentally cause a leak and unknowingly breathe in fumes all night. When it comes down to it, yeah these chemicals arent that dangerous. They're a step or two above household cleaning supplies. But really how many people handle those incorrectly on a regular basis. Nothing involved here is super dangerous or requires anything too crazy to use safely. More than anything this video felt like hey this stuff might be more dangerous than the untrained person might realize, here are some things to think about and basic steps to take to be safe.

[@vineheart01]

Same, I've had an air quality meter running when printing in my room (water washable resin) and it barely moves on any scale to the point where I was concerned it wasn't working, but then I saw the way it moved when I de-dusted my PC or bleached the toilet on the other side of the house.

I cure all my solid waste before tossing it. That includes gloves, support material, paper towels, empty resin bottles, etc. It doesn’t take much time to do in a one square foot curing box. Dirty IPA gets saved up and carted to a local hazardous waste cleanup day. The printer enclosure is vented to the outside and sealed to be negative pressure relative to the room so no fumes leak out. The fan runs even when opening the enclosure during the brief times I’m swapping the print off the build plate as in a chemical hood.

@@JustinBrown-gh9vv there is a huge difference between encouraging basic safety precautions and saying DO NOT 3D PRINT MINIATURES AT HOME, suggesting that resin printing is some ultra-toxic, ultra dangerous activity tantamount to handling nuclear fission.

This video is outright misinformation as it misrepresents the facts and frames it in a way that is detached from the reality of the fairly minimal dangers of resin printing.

[@thomasrieber8722]

Just an extra safety precaution for the miniwargaming folks, please urge your employees to wear proper close toes shoes and pants, not flip flops with exposed feet and shorts 11:23, when working in an environment with hazardous chemicals. As you had said in the video, when (not if) you spill resin everywhere, it is better to have it spill on your pants/shoes which you can remove, rather than your bare feet and legs. Otherwise, you have made good points on safety precautions for resin printing. I think it’s also important to point out that most of the 3d printing community is only running 1 printer intermittently and not 30+ printers 24/7 so the scale of “dangers” of resin printing are very different for the average hobby user.

[@TRENCHESandTREADS]

The resin isn't that hazardous lol. I've put my raw hand into a vat a few times over the years and it comes out fine, all you have to do is make sure you wash it off fully and completely sooner rather than later. The idea that getting a small spill on a bare leg is going to cause problems is a little bit alarmist tbh. You are correct though that what MWG is doing is *radically* different from the norm for most people. A room full of running printers is far different than a machine that runs for a 4 to 5 hours and then sits idle for a few days.

[@thomasrieber8722]

@@TRENCHESandTREADS I would hardly say that avoiding open toed shoes and shorts when working with potentially hazardous chemicals is “alarmist”, it’s basic lab safety procedures. And while I agree that resin is pretty far from the most toxic thing you can handle in a lab, it is still an acquired allergen and proper lab safety protocols should be followed.

[@andrewarmstrong3098]

@@TRENCHESandTREADS There is no way to know if you have a potentially lethal allergic reaction to the resin prior to getting exposed to it. Its likely not a common allergy but it is not something worth chancing due to a lack of basic safety procedures. It is far better to take proper safety precautions and avoid getting resin on you in the first place.

[@TRENCHESandTREADS]

@@andrewarmstrong3098 If you have a lethal allergic reaction to the resin the safety advice offered in this video *does nothing*, period. The only way someone with a lethal allergy should be working with resin at all is in a full blown hazmat suit, because when you pour resin, when you clean resin prints, or when the printer is printing small particles of it enters the air and can sit on surfaces for days. No amount of breathing apparatus is going to stop that from settling on skin and causing the reaction. So, like, it doesn't matter wearing shorts or not, if the advice in this video is followed then an extreme allergic reaction is going to occur regardless.

I'm amazed at how much you smell / fear the fumes. get an air purifier with HEPA filter or multiple + access to fresh air. I've worked in chem labs and I've worn less safety equipment than what you are sporting. More safety is rarely bad, unless it hinders you in the safe execution of your tasks, but feels a bit overkill

[@AlainPilon]

I did extensive research regarding HEPA filters as part of setting up my woodshop and 99.99% of what is described and sold as HEPA filter does not do the job it is advertised for. They just manage to get the requirement under very specific conditions (ex: when installed right after opening the box) or when they have X hundred of hours of use (because the filter cells get clogged up). Good ventilation, as you said, is the best solution and unless you have laboratory level equipment, the only valid and effective solution. My father died due (in part) to inhaling too much wood dust, so I am very sensitive to the topic and in the same manners back in the days they never feared the wood dust, now people arent afraid of resin fumes.

As a mini sculptor I like to do my own test prints and when I do them I take as many precautions as i can. I wear a nitrile lab suit that buttons, a full face respirator with chemical filters (dated to make sure I replace them at proper intervals), the printer in its own enclosure/room with an exhaust line drawing the fumes outside. The one thing I do different from you is I cure my solids until they are solid/crunchy then dispose of them in my normal waste. It doesn't take long to run an extra UV cycle after my test prints are done and it SHOULD render the solid waste inert as long ad I lay them out properly in the chamber.

I have 3d printed with resin for eseveral years and have found that everything you've mentioned are important thoughts to have when printing. Gloves, a mask, and where I print are always something I take into account. Usually I print in my garage which goes mostly unused and I feel pretty safe about that since the smell does not travel even into the basement where the garage is connected to. As for disposing of waste, I actually take the time to let my supports that I've used cure in the sun in order to feel okay with throwing them in the rubbish after. The harder part is the disposal of the liquids which I know I've generally tried to let the alcohol evaporate with sun exposure and the any leftover liquid resin I again leave out to cure in the sun. Those are just my thoughts on the topic, but I think k it's so great that even after years, you're wanting to make sure that people are educated on this topic!

I probably mentioned this on the last video you made about 3d printing, but after seeing just how much ends up being required for Resin 3d printing, I basically shelfed that idea. I absolutely would not have been as safe as I needed to be with resin. That might not have been that big of an issue, cause when I considered getting into FDM printing, I came to the conclusion "Man, I'd just print a bunch of stuff and get burnt out by the need to paint it all... I'd better not get an FDM printer". So I'd probably have printed a bunch of stuff and then never touched it again.

[@jowo__]

Came to the same conclusion, I'm probably overthinking the process but the idea of potentially causing harm to my dogs and my girlfriend in our small apartment is enough for me to put the idea of 3d printing on pause until I get a bigger place at least.

[@Naveication]

​@@jowo__it's specifically resin printing which is this dangerous. FDM printing with regular PLA is just fine. And modern FDM printers are good enough to print tabletop miniatures, too. The BambuLab A1 Mini is 200 bucks right now, prints hassle free, no health concerns as it's not a resin printer. Would recommend if the health concerns are the only thing putting you off from getting into 3D printing, just go for an FDM printer 🤷

[@ripath]

I work in a factory with polymer elastomers. If you are looking for a good mask I would only go with a full face respirator, specifically 3m's 6900 series. All of the components are replaceable, and it is comfortable enough to wear for hours on end. For gloves go get stripping gloves from your local paint store. Parts can go through a weakened glove before you realize that it has been compromised. We use Xylene to clean up resin spills. Toulol works better but the fumes are among the worst I have dealt with.

I would add on that a putty knife (which most people use to scrape stuff off the print plate) requires proper knife safety even if it isn't as sharp as a normal knife and it's primary purpose isn't cutting. Especially since you're handling toxic chemicals at the same time. I forgot this lesson when removing a print late one night. The knife slipped and my offhand was in its path. It caught me right where the thumb meets the rest of my palm and the fact that I was wearing nitrile gloves did not help at all. The putty knife went right through the gloves and put a decent cut in my hand that bled quite profusely. It was not a good moment and I am lucky there was no permanent damage to my hand. I have not forgotten to observe proper knife safety when removing prints since.

[@EternalQuestion]

I've been printing at home for a while, but my printer is in a garage with an extractor, on its own separate workbench, and I don't have any pets children in the house. I always use a respirator, gloves etc. and I've carefully designed my work flow so that the risk of spills and need to handle uncured resin is minimised. IMO having a washing solution that allows you to wash models before you remove them from the build plate is the way to go. Then you minimise the amount of excess resin that goes anywhere other than into your IPA. If I lived someone where this setup wasn't possible, then I wouldn't even consider resin printing at home.

[@LordWiggle]

Hey, to reduce the toxic waste, why don't you cure it first before throwing it away? You can do this by laying the uncured resin and soaked towels in the sun or a big uv light. Drop a small uv light into the empty containers for a bit to cure the inside. Then throw it away like you do, to a chemical waste processing company. You will reduce the amount of harmful and toxic material. Also, be careful with storing IPA soaked cloth into the closed off metal drum. It will evaporate and create highly flammable gas inside. A tiny spark by opening it can do the trick. You can reuse much IPA by putting it into uv light for a while and filter the cured resin out of it. This also reduces waste. There are alternatives to IPA which are less harmful to breath like ResinAway. Nice to warn people about the dangers, sad to see this clickbait title though. It is good you are trying to reduce dangers and follow regulations, yet you are far from perfect yourself with your setup and protective gear. Think about the cloths you wear and tied up hair and hair covers. The floor should be so resin won't soak into it, can be clearly visible when spilled and can be cleaned off easily. Cable management. trays under the printer so resin won't drip off onto the racks and down to the floor when spilled. Yes, you do need uv protective goggles, even with the uv protective covers down. Don't place the empty bottles in plastic bags but in drip safe containers.

[@robutegurllyman9228]

My basement is big. I have two printers next to an air purifier and two doors leading outside, I don't shock or wash minis in IPA. I spray them once or twice with IPA in a spray bottle, then I wash them in soapy water. I then take them off the build plate, put them in a ventilated box, and place it outside for a time (overnight usually). Then I bring them back in to be cured. I feel like this video may not apply to me but please correct me if I am wrong. EDIT: I also wear gloves and a mask when working with it.

[@Ryu62Alpha]

I pretty much do all this already, so this was really reassuring to watch The only thing is that I need a better dedicated space for my printer, but I have so many carbon filters around it hahaha I haven't resin printed anything new in about a year because I want to have a better set up soon

[@terricon4]

Tip, for your trash/supports disposal container, when you're done for the session, day, depending on your size of operations, take a small plug in UV light, the $20 types or so, and just hold that over the bin for a bit, turn much of your runny/soft UV waste in solid/soft instead, not perfect but definintely helps especially if you're just gonna trash it normally, like for many personal setups. In my case I also once done leave everything outside in the sun for a few days (translucent bags/storage tubs used for everything) before actually tossing. Same for water washable or washing fluids, leave them in outdoor containers that are translucent with lids off to evaporate away the liquid and cure any gunk left over. With my garage setup, if it's warm enough to print, it's warm/sunny enough to cure stuff outside like this.

[@powerup3005]

I hope this video is helpful to some people, a lot of this is purely common sense though. When I first ordered my Elegoo resin printer, they included a few pretty N95 masks, a bag of disposable nitrile gloves, and a straightforward, thorough, safety guidebook about why ventilation is important and how to dispose of resin. If you don't already know that rubbing alcohol is harmful to your skin and even worse if ingested I would implore you to take a lab safety course because I now worry about the baseline knowledge you have interacting with common household cleaning agents, and if you don't know the damage UV can do to your eyes and more I would also recommend you study up on the effects of the sun's UV radiation on human skin. Not only can it cause skin cancer, but it also just wears your skin out and makes you look older, discolored, etc. I agree that this information is important to know but honestly if you don't already know most of this outside of 3d printing I think you need to retake high school chemistry.

Great video. I have developed a severe allergy to either the resin fumes, but more likely the alcohol fumes. It manifests above my eye-lids and I get super dry, puffy and pain in that area. I now use a home build ventilated box, in a separate room, ventilating to the outside. I also wear a mask, gloves and full cover glasses. Despite this, I still feel some of the sting in my eyes sometimes.

This all the standard MSDS. Definitely good to go over for those weekend warriors. Glad to see you make a safety video

[@sicariuscat]

I appreciate the safety focused perspective from an often careless online community, but the offhand statement at the end about filament printing might be a bit too broad. Here are some quick notes: - PLA is the ‘safest’ filament, but it can still emit particles that can irritate the respiratory system - PETG releases VOCs (same class of pollutant as 3d resin) - ABS and ASA release styrene, acrylonitrile, and VOCs - Carbon reenforced filaments have the potential to deposit carbon fiber splinters on contact I’d say that the bare minimum for FDM printing is ventilation of the space the printer occupies. It’s still not a toy or something you’d want in a 'lived in' area.

[@wheelerm100]

Although not directly related but just something that you might want to consider. I became allergic to whatever chemicals are in nitril and vinyl gloves. I would have extreme hives where my hands would initially swell up, i would have hive patches over my torso and more worryingly hives on my face and head, so I would end up with a vey swollen head and face. After several trips to the hospital without much luck I came to the conclusion myself what as actually causing the hives. The simple solution for me was to stop using the nitril & vinyl gloves. This is just my experience but I felt it worth sharing to highlight that you may not be initially allergic to a chemical but can become allergic. Be sensible & safe.

i bought a $1000 SLA Printing setup, put it all in my basement, printed once and then stopped because of the fumes. i have never been able to use it since, and all my resin expired (only like 2 big bottles and 2 small ones), and i have no other place to set it up. :-/ was a major waste of money imo.

[@misatokitty76]

For me, it's getting a bit confusing. I picked up a resin printer a year ago, and washer/curer, but have yet to set either of them up because I don't really have much of a place to set them up at the moment. More than likely, it'll be in my room. I've asked multiple dealers (who 3d print at home in their spare time) about the safety aspect, and they've advised don't touch the resin, don't drink the resin, be slow, careful and methodical to prevent bumps or spillages, etc. Most suggest an extractor fan to a window, or a decent fan pointing at said window from the other side of the printer. Which sounds a bit unsafe, but... I'm not so worried about me. But I do have an 83 year old here who won't necessarily be around the printer, but is in the same house. From reading some of the comments, people are suggesting the resin is maybe a bit stronger than some cleaning products, which we have plenty of, so maybe I'll look at the extractor fan idea and see if I can make that work here. We do have a garage, and that would be my preference, but that's chocka already and dust just blows in from outside, and I don't think that's going to be good for any printing setup.

[@Philtopy]

To anybody thinking about resin printing, consider going for FDM instead. FDM printers have really reached a new peak in detail in the last year. if you use a 0.2mm nozzle, you reach amazing print qualities not seen before for that kind of printer. Yes it is still not on par with resin printers, and it will likely never be, but the level of detail is so good that an average tabletop player finds it even hard to spot that. You are sacrificing a little bit of detail you likely wont even notice that much for the advantages of: Cheap, non-toxic materials; non-toxic printing process; little to no issues with waste, cleaning or maintenance. To me thats an absolutely fine tradeoff. And think about that: If FDM printers have reached this stage in such a couple of years, they will likely improve even more in the coming years. I print minis with my Bambo A1 and after painting I find it hard to even spot the layers anymore. I am happy with that.

[@doombringer4519]

Please note that while FDM is far less toxic then resin, it is still toxic. FDM releases a ton of PM 2.5 particulates that should be vented outside as they negatively effect your indoor air quality

There is no smell in the house while printing, and barely any vocs produced. When washing the miniatures in alcohol, that's when the vocs and smell goes high, you put a mask on, blast the window fully open, it is gone in a minute - back to standard levels. Have a separate room, an open window, a mask and just don't drink the resin, you'll be fine.

The printer itself vents to the outside and is sealed in a tent and safey precautions are in place at all times when the printer is in use. So far Only my wife (who bought the printer) has used it and for the few prints I have made I have had her do the printing portion and I only did the design portion. The layout of our house keeps the printing close enough to the other areas to be easily usable but far enough to be safe.

I went into 3D printing as well before fully knowing all you need to be aware of, but at least aware of breathing and hand protection. Got my setup in a small storage room that connects to my garage, which then goes to the laundry room, then hallway and then rest of the house. But I also have the hobby room for playing board games next to the garage area. I've installed ventilation to suck the air out of the storage room, and that room isn't connected to the ventilation of the house. I've also tried to seal up the door to the garage a bit more, and sealed up the door from the garage to the rest of the house. Partly due to heating, partly due to increase the probability that air only flows out from the room and not into the garage to begin with.

Outstanding video! 👍 Question: I've purchased 3d printed items online. Some have been soft or sticky. Should I leave them in the sun? 🤔

If it's sticky it means it wasn't properly washed. Resin curing is inhibited by oxygen, so at this point you'll never fully cure that resin. Wash with IPA and an old toothbrush, wearing gloves. Do so in a bucket and not your sink. As Matt said, resin can't and shouldn't go in the drain. But a good wash /should/ help. Then evaporate the liquid.

According to everything I read, the alcohol and resin go through neoprene and nitrile nearly just as fast as latex, so what really matters is the thickness. My skin never itches or burns like it occasionally would using other gloves and they’ve never just torn apart or had holes mysteriously appear while being worn.

Not even thinking about ever 3d printing myself for all the reasons in this video. I have a appartement with no dedicated safe place to put it, let alone ventilate well. Small kid walking around, pets and I have allergic reactions to uncured resin (which kinda gives me second degree chemical burns with skin contact. And the fumes alone are enough. I used pourable AB resin once with all safety in place. Was not enough. And the reaction is not instant... takes over a day to really show fully... so no timely warning either. So gave it all away and decided to stay away from any uncured resin and it's components. Once cured it is totally fine for me though.

I have two Saturn 3 Ultra in my utility room. There are no VOCs or other harmful fumes I've seen on my air quality sensor with Elegoo ABS-Like 2.0. Been printing since 2020. My skin has come into contact with resin a few times, but I quickly cleaned it up with IPA and water. Haven't developed any allergies from handling processed minis or being around the resin yet, but I make sure to limit my exposure and handle everything very carefully to minimize mess. Helps to have a big stable work bench with silicone mats to move from printer to wash to cure. It's the IPA cleaning that sees a spike on the VOC sensor but it's still not in the red. Easy solution is to set up a fan in the window or do your IPA cleaning elsewhere. I've heard water-washable resin reeks so I don't bother with that. I'm surprised you don't have an air quality sensor in your lab, or maybe you didn't show it. I would NOT recommend putting IPA in a spray bottle. Last thing you want is atomized IPA in the air to get in your eyes, mouth, nose, or lungs.

I have my printer in a well ventilated room with the door closed and have air purifiers as well as a fan to that right behind my printer pointed out a window that I open when printing. I also have rubber mats on all my work spaces while cleaning. My wash station has an air tight seal on it. I always wear gloves and a quality face mask though not a full blown respirator because I am never doing it for a long enough period of time to really be too worried about fumes. I also post cure everything. I will cut off the supports before curing then put all the material including supports into my UV oven before throwing the supports away. For the uncured resin in the wash station I will usually let it settle out for a few days after a print (again in an airtight container) and the put the whole container outside in the sun for a few hours which will cause all the resin to cure into a spongy block which then gets removed from the vat and left in the suns for another couple hours until dry and hard. Also nothing gets left on the print bed for more than 20 minutes after it's finished printing. I also make sure before I take anything off the print bed that anything I will need to do post processing is set out and ready to go before even take the bed out of the printer so once I touch the bed I don't need to open anything or look through drawers or whatever and I have a place for everything to live while the post processing is being done. Basically make sure every step is planned out before I take the first step including emptying the excess resin in the vat back into the bottle. Been doing it a few years now and never had a spill or any other problem.

3d print at home just take sensible precautions and understand the risks. Ive been running a print shop from home for 3 years and had zero issues or ill effects. Thats not to say im immune or it cant happen in the future, just my experience so far. If you are a business that employs people the law states you follow specific rules that maximises staff safety. As in your case you are quite clearly following those rules. At home you just need to take sensible precautions. Keep it away from kids n animals. Make sure its vented. Protect from spills and wear PPE. You dont need to go nuts its not toxic waste were dealing with. At worst its a mild skin irritant and COULD inflame respiratory issues if you have any. Dont let this put you off. 3d printing changed my hobby life and my career since i do it for a living now. Its awesome and it never gets old how i can pull dope minis out of a pool of goop.

Another reason for the full face mask is to protect the eyes. I find on my extremely large prints that the fumes can get overwhelming for the eyes. Lots of burning and tearing up. Not a fun time. The chemical goggles you mentioned are probably good enough, but having the full face mask from the beginning is probably better in general I would guess. I don't notice it nearly as much on smaller prints, but when I'm running my Mega 8k pretty much at max capacity, it is a huge problem I have to be concerned about. I've also been considering getting insemination gloves that go up to the shoulder since my prints are large enough where I'm reaching elbow deep to remove supports. Haven't tried yet though, and given my glove size is typically xl or xxl I don't even know if they'd have any that would work for me. If they do work, they would probably be an affordable alternative to a lot of the nitrile options that go to the elbow.

I've put a lot of thought into how I want to get into it and I decided to take my cold cellar which is concrete on all sides with outdoor ventilation, then buy a grow tent for the printer and heat that with it in it and vent both the tent then the entire room outside with an in-line fan behind a filter. The venting system is complicated and honestly the peripherals for all this will cost more than the printer lol. I just got done sealing any potential cracks to the cold cellar and also re-weatherstripping the door. My wife and I are planning on kids soon, I don't want any risk at all. If it turns out none of that works I'll just build a bunkie in the backyard.
