@@tomhsia4354 WHAT? 🙂

[@cryofom]

If you're into tinkering and improving printers, something you could do is to splice a 25 ohm 5W resistor in series with the fan to quiet it down significantly. I did some benchtop testing to measure the temperature rise of the lamp assembly and any other electronics WITHOUT the fan plugged in. I had the UV lamp on for a few minutes straight and only saw about a 5 degree C rise. The lamp assembly has a large enough heatsink to not need that huge amount of airflow provided in the stock configuration. An added benefit on slowing the fan speed is that it won't force the fumes out into the air as fast and this opens up the possibility to add downward facing filtered fans similar to the anycubic photon s. I have noticed that the photon S is significantly less smelly so I will probably mod this printer to filter fumes as well.

For Black Friday, I bought a Nova3D Elfin. Things I’ve learned since - all the precautions taught in Chem 1A apply. The LCD screen used to create the mask will fail and require replacement sooner than you might expect. It’s seems to be a good idea to use 99% IPA but I have heard that something like Everclear pure grain alcohol would also work well. Mean Green and Sprayway work well for non-translucent resins. An inexpensive one or two litter ultrasonic cleaner should get parts really clean in about 3min. A nail polish UV curing lamp can be used to complete part curing - my UV flashlight works really well. And a proprietary mind set sucks. The Elfin requires NovaMake, which has significant shortcomings that ChiTuBox could overcome but It doesn’t save in .stl and Elfin cannot seem to parse a .slc file. And finally - I need to become far more proficient with MeashMixer if ChiTuBox’s .slc files won’t work reliably with Elfin or NovaMaker won’t add “make hollow” and “add hole” features as easy to use as ChiTuBox. Both of which fall squarely on Nova3D’s shoulders. But man I sure love the quality and speed.

Hey Joel - As a respiratory therapist, I applaud that you took time to explain and warn against the potential hazards of inhaling SLA resin vapors and fumes. >15 million people have asthma in this country alone, and environmental/occupational/recreational + other types of chemical exposures contribute to that problem as well as other types of pulmonary disease. On a macro level, we can all probably appreciate that inhaling large amount of resin vapors could be harmful. However, one of the things that often goes overlooked is the effects of very low dose/long term exposure (as opposed to a brief high dose exposure). As these devices become more prevalent in homes, I can foresee that there will be some people who are adversely affected largely because of ignorance of the risks and carelessness. I think it's great that you took the time to point out the potential risks and appropriate handling and use of UV resin and I hope that everyone who watches this takes heed. Thanks for all you do. You're an excellent teacher and role model. Now, where was that Amazon link?

[@TravDadGamer]

Hi Michael - is a standard 3M replaceable filter mask, like you might get at Home Depot, good enough to protect oneself? And what about resin dust from the air getting on the skin?

[@BrenzMarie]

​@@TravDadGamer Hi Travis - I am not an absolute expert in this area but, by virtue of my professional experience, I might have a tad more knowledge or intuition in this area than the average "man on the street," but I would certainly defer to someone with greater experience than I if they are reading this and wish to contribute to the discussion. In looking at personal protective masks for any application, you would need to determine whether they are rated for just particulates, or also include vapors and fumes. Vapors and fumes are essentially gases and cannot be removed, in a mask, by particulate filtration; they must be removed chemically. This typically means a different type of mask with an absorbent cartridge whose design includes the specific chemicals you wish to exclude. These may or may not be readily available commercially. However, FDM and SLA 3D printers do not require the user to wear personal protective gear provided that common-sense precautions are observed. These include: 1. limiting your exposure proximity and exposure time if you are an asthmatic or have chronic lung disease; and 2. using the device in an area with adequate ventilation (an exhaust hood, an exhaust fan, an open window, a well-ventilated space, etc). Manufacturers typically provide device-appropriate warnings and cautions that should be followed if their devices have the potential to expose users to possibly harmful particulates or vapors. The point I was trying to make in my original comment was that some people will likely ignore those precautions for any number of reasons. Joel was probably cognizant of that and decided to error on the side of caution by emphasizing the small, yet potential, hazards. I high-fived him because, as a respiratory health professional, I was happy to see someone in an influential position being so responsible and cognizant. I believe that the vast majority of people, provided that they read and follow the precautions specified by the manufacturers, will not have any problems. Regarding your questions about resin dust getting on your skin .... I don't think there is any resin dust from the SLA printing process (only some vapors). However, in post-processing, if you are sanding an SLA resin model, for example, then there is a possibility of sanding dust and you should take whatever precautions are necessary to make sure you don't breathe it. As for me, as soon as I save up the requisite dollars, I'm going to get one of those new SLA printers. I have a spot near the window reserved for it.

[@KX36]

I just really wanted SLA because it seems like less dicking around and insane detail (was looking at elegoo mars or the anycubic photon)

I snip the supports of before curing because it's usually more flexible at this state. after curing, snapping thin supports can stress and break a connected thin part.

[@Arctic611]

The reason to cut the supports off before everything cures all the way is that when you do wait they tend to snap and not cut. When they snap they make a small concave on the part itself so if you're not extremely careful you will get pits on the part and depending on your tolerances that could make it useless. When the resin is still that little bit soft, it will rip and shear. It looks worse at first but it rips straight across or even sometimes pinches so it leaves a convex surface on the part that you can sand down later (or take off with a Xacto). Also with more delicate parts, letting the resin cure all the way could make the support just as strong as the part itself so sometimes cutting it can make a piece of the part snap off just from the movement of your blade or snips. TLDR: It's faster to cut if it's all cured and often a lot of the work can be done with pressure rather then tools; it's more precise and cleaner cuts that have less of a chance at ruining detail on the part when it's not cured all the way.

[@elfpimp1]

Wow, that's some sick detail for a printer at that price. I can see myself using this to reproduce casting molds for small metal parts no longer available for classic cars.

[@Diegesis]

there is a benefit to snipping before curing. pre cured resin is softer and easier to snip. once it's cured it's quite brittle and increases your odds of breaking your model while snipping.

[@ckaiser022]

To help get the parts off of the printer buy a piece of stainless steel the same size as your build plate and keep it in the freezer. When you are ready to take the part off place the build plate onto the freezer plate and leave it for around 10 ish minutes and it should pop right off without any breaking or any effort. That is what we do with our resin printer at work and the parts basically fall right off the build plate!

[@Heavens_Rejected]

So I have both an FDM printer (plastic filament) and a DLP Printer (resin). If you break the support material off before curing then I believe you would be less likely to take small chunks of your model but I personally chose to do it after curing because of the fact that I also have the FDM printer. I do so after so that I don't need multiple sets of tools I need to keep track of since you don't want to use the tools coated in uncured resin while working on other projects.

[@truantray]

I have a couple FDM printers, recently bought an Anycubic Photon. For small detailed prints, LCD resin is the way to go. It's faster, easier, and printing 6 of something takes as much time as one. No layers, none of the plethora of issues with FDM, literally 100% build success and small parts are far stronger than any filament. Resolution in XYZ is measured in microns. They polish or paint beautifully. Prints can be optically clear. You can see why industrial printing is mostly resin-based and this is likely the future. It basically is a tool any 3D printer needs to make small prints. Small point: UV wavelengths are below 400nm, 405nm is blue light. This is used because under 400nm light would generate ozone. As for the fumes, yes, do not breathe, but fumes from ABS filament are just as bad.

[@bboydradle]

There is a distinct advantage to trimming support before curing. Because the uncured resin is less brittle, you can get cleaner snips that don't leave negative pocs in the surface and then sand anything remaining off. If you snip after cured, you risk shattering and pulling more material away. Also, the resin is actually more flexible before curing, so it is not as you said less strong before curing.

Pro-tip, when you buy gloves buy two different sizes. That way one fits extremely tight, and the other one will be looser. Reason being that when working with prints, there will be times that you have soaked gloves but aren't done working with the print. At those times, you take off the outer gloves leaving the print inside of them if possible. Then the other set of gloves are ready to go and you don't lose time putting another set of gloves on...

From my experience I prefer to snap off supports before curing as its generally easier (supports are flexible and easy to tear off), if removing supports after curing it can require a bit more effort as they're stronger and more brittle and can in turn cause blemishes on the surface (not an issue if you plan to do any post print work like sanding), though I just do it when reasonable, if I print a miniature with a thin weapon like a sword I'll remove supports on chunkier stronger areas of the print, cure it all for a few minutes under a uv nail lamp, and then clip off supports around the sword

[@LincolnWorld]

Thanks for another good video Joel and Sean. I got a different resin printer that uses the LCD masking recently. The results are amazing! But the messiness and potential safety issues are not great. Most people from what I've been reading clip off the supports before final curing because they tend to come off cleaner and don't shatter like after final cure. That has been my experience as well.

[@mislavenart]

Some advice when resin printing: - if you want even more detailed print, try using a painters brush when the print is in clear alchocol al gently brush off the surface to get all of the uncured or halfcured resin off. - when pouring the rest of the resin back, try using a plastic funnel and put the filter in the funnel. This means there is no additional hands needed, and fiter hole is not to big. - before pouring it back, shake the bottle to get the resin in homogenous state - clean the platform and all the tools used with alchocol. - if print delaminates it is posible to weld it back by just brushing resin back on and curing it - best way to cure is with a curing station, but also there is that thing girls who do manicures use. It also emits UV light and is fairly cheaper. This reduces the curing time. - ALWAYS WEAR GLOVES P.S. Its easier to get the support before curing, but it's also a way to breake yout print if there is some thin shapes or geometry

Yes these printers are more messy than filament ones but they’re not that bad. With a little organisation it’s really easy to keep things clean and deal with new prints off the machine. I haven’t found any issues with the resins regarding contact with my skin or smell even in a small environment. I would always recommend you follow the manufacturers instructions but you’re not dealing with toxic waste. I find a lot of these reviews exaggerate how bad it is to work with resin when its safe and easy if you have any common sense. Don’t use a playing card unless you’re planning on wasting a tone of them, use a plastic tool that can be cleaned and reused.

[@7525916]

Often it is easier to remove uncured supports because they are softer. It's a judgement call, you can remove them while the model is soft, but small thin pieces are more likely to break off. I will pull/snip off supports usually after an IPA rinse but before curing.

[@jonnyBgood3]

What about glasses as well as gloves, I wonder the effects of getting a splash in the eyes and it soaks in then cures?

[@MikeHammer1]

Since the printer does a full layer at a time, the center of a non-hollow print should be solid, though perhaps not as well cured as the surface, since UV finishing light won't penetrate much beyond the first millimeter of the exterior.

A note on the safety aspect: I once spilled resin over my hand and to be honest it caused some irritation (burning sensation). Another time, while tearing away supports by hand a stray support ripped my glove and cut my thumb. Resin got into the open wound and... nothing. No sepsis, superpowers, nothing. But the area around the wound would burn as I mentioned before. Apparently some people feel nothing while others have extreme responses. And anywhere in between. Rather don't take the chance.

Seeing this cheap resin printer has me excited to see what will be coming in the future and I would like to try resin printing, but for an entry level hobbyist, it's still impractical even at 229, imo with all of the other factors taken in to account. You need to live in a sunny area or build your own uv curing box. You really need ventilation, and it looks like this machine does not come with any parts for that, I've seen a dangerous attitude in the community that if a resin does not smell it's fine to breath in, even non-smelly resins are still emitting toxic fumes. Respirators if you want to be really safe (especially when sanding). I'm not sure if you've covered this in other videos, but that uncured resin slurry also needs to be recycled at a center as hazardous waste, it cannot be poured down the drain or capped off and put in the trash (ethically at least). The resin itself is expensive, and more suited for jewelry or prototype casts for molds than making the usual desk trinkets hobbyist tend to print. All that said, I do think it's amazing to see SLA/resin printers reach these low prices. I just think the average FDM enthusiast does not really need an SLA printer or is going to prepared to do all of the secondary things you need to do when resin printing. (Outside my mini rant(?))

Anycubic, and from what I can tell most other companies, have a 12 month warranty that covers everything besides the LCD screen which has a 3 month warranty. That's because these companies regard the screen as a consumable, as they so often fail with regular use. They're relatively inexpensive to replace ($40-75) and easy to install. You'll notice that a lot of companies have videos on their youtube channels showing you how to replace the screen as well as the motherboard. That should tell you something. The 12 month warranty on everything else allows them to send you replacement parts that you have to install yourself. And I like to remove the supports before I fully cure it but after I do my first rinse. The small bumps and nodes left behind by the supports are much easier to scrape or sand off before the resin fully hardens and gets brittle. But to each his own! Then finally with the filter funnel. I purchased a cheap funnel from an auto parts store and I place the filter inside of that to prevent that overflow spillage. I lost half a bottle of my first resin after it spilled over the sides. Hope this helps someone!

It is super cool to see that the resin world is getting cheaper so that we can see more people in it. I do have a couple of questions, as you stated, resin printing dose have some risks, do Longer3D provide sufficient warnings and instructions in the box to inform newcomers that dont know anything about the printer? And are we going to see resin 3d printing on the channel in the future as a staple other than machine review?

[@jesondag]

So much easier to remove supports before curing. Gives a cleaner result too. Even easier, in warm water.

[@KevinRank]

This is what I do. Pre cured are softer and come off easier and are MUCH less likely to leave divots.

[@jordongingrich8913]

I see sean was having fun with Vanellope..

[@AndrewStAngelo]

At 8:25, at least. Until I started stepping through the frames, I thought, maybe, I was seeing things. That's crazy. Does Vanellope often make an appearance?

[@PatrickHodge86]

I'm glad someone else saw it too.

[@kaldo_kaldo]

I saw her like 10 times in this one video.

[@maxmoors]

11:28 - Sort of, since the resin isn't fully cured it means it is easier to break off the supports but you have the downside of breaking the models easily. I used to work with the Black High Def Acrylate in Shapeways (mainly printing the Hero Forge models), and we always used to cure the models after removing the supports.

[@camoman619]

I wonder if you could take the rail system of an FDM printer and mount an LCD to it to combine the volume of FDM with the precision of Resin. You could use the software to have the screen scroll through the pixels as it moves, almost like a magnifying glass over a picture. Obviously speed is the major drawback here but if you have to make something very precise or without the problem of layer adhesion, then this could be a cheaper solution than a larger LCD

[@evo-labs]

Lol, that was exactly what I was thinking while watching this video. It seems like a logical solution.

[@andreas.grundler]

I recently saw a review of another Resin 3D printer on the channel Design Prototype Test. In this video you can see how someone behaves who ignores all the safety instructions in the manual.

[@DBijl]

You mean you start seeing Chinese conspiracies everywhere? Must be due to the fumes.... ;-) But yeah, safety is key with these things.

[@andreas.grundler]

He also touched the printed objects with bare hands instead of using the gloves. Some of the resin has dripped onto his skin.

[@Ron_Ventura]

DPT doesn’t “do” instruction manuals. He’s above all that. He’s a “FIGJAM”. What’s that? “F#@k I’m Good, Just Ask Me”. I find his rants irritating. Won’t watch any more of his videos.

[@DBijl]

@Nick F It is not the short term that is the problem. It is about long term use, repeated contact with the skin can create a sensitivity for the components in the resin and being exposed to the fumes can eventually cause brain damage. How fast that will happen differs from person to person. Some people are super sensitive, others will never notice anything.

[@DBijl]

@Nick F Not sure where your other response went, can't see it, only got a notification. But here is a study of the long term effects of chemical fumes (in paints and glues, the same components are also in resins) Occasional use generally is not going to be a problem, but if you make a long term hobby out of it, it is better to be safe than sorry: www.aan.com/PressRoom/Home/PressRelease/1285

[@DanFrederiksen]

We need to combine the raw material side and the non mechanical guided development side of 'resin printers'. Not just general plastics but indeed metals and any combination of materials. We are actually pretty close to some genuine scifi stuff. I think a vacuum cold vapor deposition direction will get us there in first incarnations. It doesn't matter that it's a little elaborate or expensive at first, there is tremendous value in getting it actually right instead of ugly frail STM prints. Think of the power is being able to print a small jet engine and electric motor. Including all the structure, insulation and copper wiring. Or silver if you feel fancy. At cast strengths or better. You could print a functioning loud speaker. A good one. The best one. One so good that all traditional manufacture will be abandoned.

[@bipolarchemist]

Love that you mentioned ventilation. I would argue that is a bigger issue than getting a small amount of resin on you. Esters of acrylic acid or methacrylic acid smell horrendous unlike the esters you probably made in o-chem.

[@SculptyWorks]

How hard is the fully-cured resin, compared to say... a PVC pipe type of plastic?

[@SculptyWorks]

@@Michael-nn2ho Thanks! 👍

[@TimPiatek]

Question: why not filter OUT of the bottle rather than going in? In the event of an over-spill, it just enters the tank of the printer. Any real downside except the danger of forgetting?

I was an early bird for this Kickstarter and I’m really pleased to see the first few hands-on reviews. I’ve been using an FDM printer for a couple years now and I’m looking forward to getting into the resin arena. Can’t wait to get this (noisy smelly) baby in my own hands.

[@3DPrintingNerd]

Wait was the 10 a kickstarter? I thought the 30 was the Kickstarter one?

[@DTyrannosaurus]

3D Printing Nerd Yes, sorry, the 30 was the Kickstarter. Supposed to be shipping in August.

[@dmthandmade5674]

I use a disposable jaegerbomb cup with the bottom of the shot section cut out for draining my tank. Filter goes in the shot section poking through the hole where the bottom was, the shot section slips down in the neck of the bottle and the outer part of the cup serves to catch runoff if you pour too fast or it clogs and spills over.

[@Deadpool_collector247]

I just started with 3d printing at start of year, got the Anycubic Zero, wash cure station and 1l resin for £170($210ish). Looking forward to getting the mono x soon

[@evankemp]

Thank you for making a video around the safety of resin printing

[@Yakeru35]

What's the state of LCD panels durability when subjected to UV light ? A few year ago, when reading about DIY resin printers, the premature wear of LCD and DLP panels subjected to strong UV light for long period of times was a serious concern. I know Prusa uses LCD panels in their SL1, and I believe we can trust them, but cheap printers like that ? Is there a range of UV resistant panels now ? If so, is there a way to know if that's what they are using ? Was it a non issue in the end ? So many questions :-D

[@MaxGoddur]

Several questions: How long after you print an item do you have to place it in the alcohol tank? How long must it remain in the tank? If you forget it is in the tank of alcohol will it hurt the item? How long after you take the item out the alcohol to you have before placing it into the UV curing step. And lastly how long will the need to be under UV light?

[@NextLevelTech]

11:19 There is no advantage to snipping off the supports before it has cured. Thats like taking Ice out before it has frozen, thats like sitting on a bench with fresh paint and a sign that says wet.

[@Tuitjemobiel]

if you use square containers with alcohol you don't have to remove the prints first. You can rinse them with plate and all.

[@pesto12601]

You are not supposed to get the plate full of alcohol..... it can ruin it.... BAD IDEA!

[@Tuitjemobiel]

@@pesto12601 OK, Sorry.

[@maclaird1]

Clipping the supports before curing will give you a cleaner surface. I often have no bumps left at all when I do it this way

[@laurarosario532]

How many D&D size minis can you get out of 1 bottle of the resin?

[@EMDream1990]

I'd like to know this as well thinking about getting it to print my own minis

[@beaug.2326]

This is the exact reason I'm watching the video! I want to print my own minis

[@ninetails6218]

“D&D” isn’t a size. It also depends on how big your bottle is.

[@laurarosario532]

Well, let me reword the question. How many 28mm figures can you get out of a small (500ml) bottle of resin?

[@ninetails6218]

I have heard somewhere between 20-30, though assuming for support waste I’d lowball to 15-20.

[@jimmcclure3657]

I totally want to get into resin printing. That is, as soon as nitrile gloves, rubbing alcohol, and protective masks are available again-someday. (If you're reading this years later. Still the coronvirus pandemic 07/2020) I'm curious if you had resource you could share that shows the multitude of resins available that can used. I'm curious to see if resin jewelry can be made with a "resin flow" technique. And also, lastly, I'm seeing metal based resins now. Do you have anything on your channel(s) that show how durable that might be? Great video. Very helpful. Thank you!

With this machine could you replicate a diecast car body? Not the entire car, but the hollow body? Or even model car parts?

[@brianbright7501]

So the resin sells for 50 dollars for a bottle 500g, roughly how long will that last. How many of those rings will a bottle make?

[@MrPruske]

Not enough. Lol if you are efficient with your modeling, it should be only marginally less than pla

[@andy-in-indy]

The FEP film lasts a few prints (5-20 depending on how much bonding any particular area gets) and can be sourced on Amazon and other places ($20 for 8-12 replacements). There is a "Pickle Strainer" jar that is an easy way to soak the pieces in alcohol and pull them out without sticking your fingers in there. Not the cheapest version, but here is an example: smile.amazon.com/gp/product/B002KKCLI2/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 *The resin in alcohol is more hazardous to you than the resin by itself (the alcohol helps it absorb into your skin faster) so don't be tempted to pull things out of the alcohol without gloves!* Using a box fan (the cheap $20 fans from the hardware store) on high to pull the air out of the room will provide good ventilation for a garage or similar sized room. Make sure it is pulling the air away from you.

[@samueldennis8343]

We had this machine and the orange 120 at work along with a photon s, Uniz slash, FF Hunter, LD001 and the only one er couldn't not get a single success on was the orange 10! Their 120 machine is insane for the price and we use it all day everyday!

[@3DPrintingNerd]

Thanks for the info, I’ll look into the 120!

[@samueldennis8343]

@@3DPrintingNerd Would be good to hear your opinion! In its current state it only prints over ethernet or WiFi, longer are working on firmware so you can print from a USB. A tip if you come to testing one over either of those, make sure you disconnect the machine/close the slicer as it eats up all the bandwidth and basically makes browsing the Internet impossible. Strange because it uploads the file to the machine first so whilst printing you are just monitoring the print but hey ho! Amazing printer nonetheless! Keep it up Joel! 👍

[@alexstixx]

So, snipping the supports off before curing makes it less likely to crack the printed part at the points where the supports connect to the model. Curing the part with the supports intact after an IPA bath means it's less likely to warp during the final cure.

[@xaxuelx7987]

In the future, when you present several model examples to viewers, I recommend printing two of the same model; a plain version and one with an acrylic or ink wash to pop the detail. Cheers.
