All SLS parts are 100% solid, unless you make a hollow object with drain holes. Even if some of the powder didn't fuse, I don't think you'd be able to tell with xray since it'd be full of powder.
@@randomblock1_ It's a problem that's been documented with metal sls parts where tiny voids form during the laser melt process and can really negatively affect the part's UTS, yield strength as well as fatigue behaviour. curious if this printer's material and/or setting combination still displays similar problems
@renchesandsords I don't think plastic SLS has that issue, thermoplastics should be more forgiving than metal due to them not having a concrete melting point. But you're right, it would be interesting to see
@@randomblock1_ SLS isnt perfect, if you dont use supports the molten plastic/metal can sink into the powder and result in a bad surface, this might lead to micro voids etc
I'm glad there's more options for SLS. SLS has been a technology that's been too expensive for most to use. At ~3K, this machine might not be cheap... but when the most popular alternative starts at ~20K, well definitely opens up possibilities.
and that alternative also requires 2 relatively beefy people to transport, whereas i can chuck this thing in my back seat, strap it in, and take it anywhere i need.
Safety is also more important with this than a lot of people realise, that powder is really nasty for your lungs and it will get everywhere. From what I have heard from people with experience using SLS machines is that they are not suitable or safe for home use and that this printer doesn’t change or address those issues at all.
@@conorstewart2214 And resin can also emit nasty fumes. Yet, it is still perfectly usable if people listen to the instructions. Conversely, you wouldn't use a power tool to drill or saw into your own hand, no?
This video's gonna need a Dune case style retitle. Formlabs bought them out because they were gonna make something just as good at a fraction of the cost. Now it will never exist or will at an exorbitantly higher price.
The thing about the build volume is that unlike an FDM printer, you can truly fill the build volume top to bottom, as there is no requirement for a "base" that's touching the build plate, like there would be in a FDM printer.
important notes to all: 1) it needs to be in a room with inlet and outlet filters. Even with that, always use masks when it is in use, no exception. 2) It is not ready yet, but soon it will be. So, they need to fix issues first.
The way how to move out the power is very dangerous. They still have a long way to go. And how they was covered with powder in the end is very worrying. This power should not find the way to your lunges in any way. It needs at least one year in further development, at least.
@@mabbasi_ofI've used their sifter and yeah the Formlabs sifter method is way better, it gets unpacked in a vacuum hood. Anyway, yes, a mask, gloves, and ventilation are needed for all SLS printers due to the nature of the powder.
people will use this exactly like they use resin printers, completely ignoring any safety or just being ignorant there was ever any need for it. I've seen people that print resin in their bedroom. But it can't hurt throwing out some good advice for the few that will listen.
There are safety concerns with SLS printers that should be talked about far more than they are. There are lots of people with experience using SLS printers that say that this technology is not suitable or safe for home use, that powder is very bad for your lungs and just wearing a mask when using it isn’t enough, especially since the powder gets everywhere and can get kicked up later. Like other things, laser cutters, it seems that LTT aren’t too concerned about making the safety aspect of things like this known.
Let me worry about my own safety. If you can have a table saw, insecticides and herbicides in your garage you can have nylon powder as well. Knowing safety risks is important. But saying the average person shouldn't have it because it's unsafe if not used properly? F that.
@@NerdSnipingBatman With nylon powder, we do have to worry about your safety because your safety is everyone elses. The powder collects in your clothes, hair, on surfaces etc and can be kicked up and made airborne at any time, making it the problem of somebody who didn't consent to the risks. Don't be so selfish, this machine *needs* a totally enclosed post processing system at the bare minimum if every average joe with a credit card can get access to it.
Now that they are acquired by the Formlab, this printer is dead. The seemingly impossible task to create a SLS printer by 2 college kids means it's doable. One of the 2 kids is Chinese so he probably knows how to source parts from ShenZhen. Therefore, an equally resourceful and innovative company should be able to build a similar printer that's within $5000. Please Bambu, sell us a $3000 S1 SLS printer! You can have more fancy post processing stations that add another 2k and people will line up to pay!
Probably the most earnest piece of LMG media I've seen in years - including the apology videos. Please let this guy chat about maker kit when he wants to! His vibe is great and really refreshing!
Must admit sometimes 3d printers more feel like 2.5d printers, when you always need to think about orientation and stuff while you are modelling the part, this thing is next level, real 3d printer.
It's exciting to see how the Micronic SLS printer revolutionizes the way parts are printed. It's great that its price makes it accessible to individual artists and small businesses.
I see Linus and Luke's son shaved his beard to match with his short dad. This printer is seriously amazing, I do FDM 3D printing at home as a hobby and I really wish I could afford this, suddenly you could get strong prints with way better finish than FDM and with way more detail, this machine looks amazing.
If you use ironing in your slicer, and you're extremely patient with your prints, you can use 0.04mm layer height and a 0.1mm nozzle and get extremely detailed almost resin quality prints. But then you have to wait a whole 2 days for that detail. If you just add ironing though you will get rid of most layer lines.
Looking at other UA-cam creators that have been given these units for advertising the kickstarter, I'm very surprised how little issues were found/shown in the
Sounds a bit like Linus and his approach with Amazon “we don’t like them and don’t use them, until it’s convenient for us”. You’ve made such a point of avoiding kickstarters and now you make an exception essentially because “we think it’s cool”
I thought that sintering *doesn't* melt/liquefy the material, it just "fuses" it together? SLS stands for "selective laser sintering", but there are also SLM or "selective laser melting" printers. At least for some metals, the melting point is too high to practically and accurately manufacture something using a laser, so sintering specifically *doesn't* melt the metal. Although Wikipedia says that sintering "doesn't have to" raise the temperature to the melting point, so maybe *sometimes* sintering does mean melting, but not always?
Maybe it depends on the material used and the time of exposition ? Here with nylon powder we can reasonably expect a laser to melt the thin layer of powder, especially since it is pre-heated with strong halogen bulbs
@@bastienx8 That's very much possible, I was just under the impression that sintering specifically means "no melting", but maybe that's not always the case. I've never looked that much into the topic, because SLS printers are so expensive (even a "budget" one like this is $3700).
@@SamiKankaristo Yes, SLS does not melt the powder, that's an easy mistake to make, I wouldn't roast Tynan for that. as in most SLS printers the unsintered powder is very loose, actually melting the powder can quickly lead to voids forming and ending up in print failures.
@@Chaosghoul I wasn't trying to roast him, I was just a bit confused whether it actually melts the material or not (I've never really understood exactly how sintering works, I've just read a bit about it).
The main difference is temperature in the chamber and output of the laser unit. For polymer sintering the chamber is brought up right under melting temp of the material used. In metal laser sintering the chamber is heated, shielding atmosfer is provided, but all of the energy needed for fusing the material comes from the laser unit. We are talking about single kilowatt laser unit in one machine depends on size and usage designation. For the SLS we are talking about couple of watts at most. Hopefully it makes sense why they differ and why sintering and melting is used for each of them
I had some contact with the devs about technical questions and the (non-)responses were fairly disappointing. Especially as a tech CTO myself I'd have given detailed responses to how I approach specific technical challenges. Additionally, the refusal to open source at least fw/sw for something like this is a really bad sign. Stuff *will* break and there's no guarantee a startup will remain in business. With OSS FW/SW/(ideally HW), I can debug and fix issues myself. For ref, the questions were stuff like "how do you handle chamber heating uniformity and waste heat?" and the answer was one word "engineering." or "is an inert atmosphere required? if no, how do you handle oxidation" and they replied "we didn't encounter any issues". Chamber heat uniformity is a huge problem in industrial SLS, to the point that printers have thermal imaging cameras built in. An answer like "engineering" does not built trust in a printer like this. Industrial SLS requires nitrogen to get proper material properties and keep the refresh rate low, and even then they're 30-50% depending on vendor. Micronics claims 10%. This all stinks like under-engineered vaporware where you'll end up sitting on a dud. Oh, and even non-technically.

Yeah, none of this souds good. I remember a company rep extensively talking about their round chamber and how it helps with uniform heating. And that's almost 4 years ago. It leaves me with an impression of couple guys macgyvering something on their knee in a garage vibes.
@@the_tiny_Rambo I'm not per se against macgyvering, especially as a startup for your first handful of units (even at that price, as long as the customer support/expectations are set correctly). But when you try to present yourself as a well-engineered machine...
@@kanetw_ I didn't mean to look down on it either. I think my sentiment is similar to yours. I think with the complexity of sls printing they should be knowledgeable enough to know how to present themselves in direct communication. And if they can't do that it raises questions about what else might not be as good as they want it to seem.
I would suggest that you watch our videos before making comments about us not being transparent - start with "designing & building the Micron SLS 3D Printer."
Very cool device but man working with powder seems like a huge pain, think I'm probably going to go the SLA direction instead when I upgrade from my little PLA extruder
The creators were clearly inspired by modern electronic Litter Boxes for cats. I mean size, colour, shape, plus you get a scooper, a sifter, and in line with that experience you wait for it to finish 'excreting' and then you have to remove what it 'excreted' from the remaining medium.
It depends a lot on which media you're using, what PSI, etc. In theory you could buy a machine to recycle the blaster media. However the powder that sticks to the sintered print is not really usable because it's significantly more fused than leftover powder. I mean you could try but it wouldn't be as good as powder you shake away.
Blasting media is almost always consumable particulate from what you are processing gets mixed in over time. Some media blasters have filters attached that help get rid of some of the powder but after a certain amount of time and material processed the blasting media gets disposed of.
Most of the time preform is great, we frequently print weird aspect ratio and sized parts and can end up with super low packing densities with auto positioning. Also the whole "self automatic packing" feature in micronics' slicer is very cool to me a a concept and in implementation.
This is cool and I love that this is on such a huge channel. Ive recently gotten into FDM and Resin is at a point where I'm comfortable with doing it when I can afford to. If this becomes affordable enough in a couple years I'm gonna cream my jorts
Small clarification. The shapes need to be hollow and closed, since you need to be able to remove the non-fused powder. A big question is how much does the powder cost. We already know how 2d printers are so affordable and the crazy prices of 2000$/kg that Markforged wants for its CF-Filament.
is it just me or does his shirt look weird or off. the way it goes from the collar to the armpits like at 6:22 it is almost bunching up like he has a backpack, posture corrector, or shoulder gun holster on. is it a pre production shirt that isn't finalized?
I kind of miss the hazard POV that comes with SLM / PBF fusion printing. The Nylon particles arent good for the Lungs normally Cleanrooms are used for SLM Workstations. Imho it s not possible to print via SLS at home or at least far from ready at this point in time
Binder-jet printers also have that powder-is-the-support thing. So with them you can also do the just-chuck-all-the-parts-in hack (that I'm embarrassed I never thought of before).
There should be an updated describtion, Title and a pinned comment with the information that Micronics has been acquired and cancelled the Kickstarter.
Scotty, from Stranger Parts, also reviewed this model. He did run into quite a few big problems, and not just with the printer. ua-cam.com/video/zmlt_FXaz1Q/v-deo.html
Not to mention VERY shady business tactics like asking him to delay the video until the Kickstarter has begun or ended *and* they demanded the printer back because they "felt their hard work was not appreciated". They also very openly told him that they want to start the Kickstarter despite all these issues because they are running out of money... It's a cool product but how many more red flags could there possibly be...?
@@MattisProbably they wrote on their website that anyways the printers will come back because they need to come back to test and they didn't wrote it yesterday but at least 2 weeks ago
dude has powder all over him at the end of the video... fuck this.. that shit is horrible. The PPE is extremely insufficient. You should do this in a bunny suit with a legit fitted mask. The top of the device should also have fans and filters; this should be done in a shop in an enclosed chamber with filtration, etc. This dust is not lung-friendly, will never go away, and gets everywhere.
If I ever need an SLS part, I'd rather pay someone to do it. There's too much toxic dust and it's a lot of work. FDM is still my favorite. It just sits on your desk, ready to print the next part. You usually don't even have to level it, just check if the spool isn't empty and hit print. And $3,000-$4,500 is still a lot of money for some metal parts, a sheet metal case, and plastic components, and all from a company with zero experience and no track record. 🤔
Yeah, SLS will probably never end up as a consumer product. Nobody wants to wear a mask and gloves and get powder everywhere. But companies will LOVE this. And so will makerspaces.
FDM releases VOCs also Especially if you're printing TPU or ABS. Really no 3d printing technology is good for your lungs. Resin of course is messy but at least because the majority of the particles are heavier than air it's more of a risk to your skin, face and eyes than your lungs. Either way: all of them should be done in a separate room with good ventilation and PPE.
@@NerdSnipingBatman SLS is a particularly nasty process and worse - it's not intuitive why. Alongside the not-well-known risk of inhaling plastic powder there are fire and explosive hazards working with large quantities of such fine particulate. Alongside extremely disciplined PPE and ventiliation you really should be buying an explosive proof vacuum to operate this too...and those are several thousand dollars themselves. I think companies should be able to make good use of this product but SLS is absolutely not something I'd ever recommend someone have at home. Even if it's in a separate room or garage.
Hi , this machine is definitely not production wise ready, there is a huge risk to loose several thousand dollars with this kickstarter campaign in despite the idea is very nice
SLS seems sooo much more useful. I've got an FDM and the fiddlyness of it really does turn it from a tool to a hobby, which may be great for some but I just want to click print and come back later and not fiddle with retraction settings or some other nonsense.
I'd love to see you take a look at resin printers too, just ordered a Saturn 4 Ultra from Elegoo and hoping its great, other reviewers love it, but your take on this stuff would be great

Tynan is so handsome I don't know a single word he said.
How do you clean your sandblasting unit after? do you throw away the blasting medium, can you recapture the nylon that comes off?
It depends a lot on which media you're using, what PSI, etc. In theory you could buy a machine to recycle the blaster media. However the powder that sticks to the sintered print is not really usable because it's significantly more fused than leftover powder. I mean you could try but it wouldn't be as good as powder you shake away.
Blasting media is almost always consumable particulate from what you are processing gets mixed in over time. Some media blasters have filters attached that help get rid of some of the powder but after a certain amount of time and material processed the blasting media gets disposed of.
LTT needs more Tynan... He's like the Henry Cavill of tech!
very very surprised you have had issues with PreForm, it's the best slicer out there IMO.
Most of the time preform is great, we frequently print weird aspect ratio and sized parts and can end up with super low packing densities with auto positioning. Also the whole "self automatic packing" feature in micronics' slicer is very cool to me a a concept and in implementation.
Tynan is an excellent presenter. More from him, please.
This is cool and I love that this is on such a huge channel. Ive recently gotten into FDM and Resin is at a point where I'm comfortable with doing it when I can afford to. If this becomes affordable enough in a couple years I'm gonna cream my jorts
Small clarification. The shapes need to be hollow and closed, since you need to be able to remove the non-fused powder.
A big question is how much does the powder cost. We already know how 2d printers are so affordable and the crazy prices of 2000$/kg that Markforged wants for its CF-Filament.
is it just me or does his shirt look weird or off. the way it goes from the collar to the armpits like at 6:22 it is almost bunching up like he has a backpack, posture corrector, or shoulder gun holster on. is it a pre production shirt that isn't finalized?
I didn't knew this was Tynan without his beard until I heard his voice in the video
SLS is what they made those new basketballs with, right?
I was looking at the kickstarter today, sadly I cant afford, would love to get my hands on one of these.
I kind of miss the hazard POV that comes with SLM / PBF fusion printing. The Nylon particles arent good for the Lungs normally Cleanrooms are used for SLM Workstations. Imho it s not possible to print via SLS at home or at least far from ready at this point in time
a grown up Linus do we have here
This looks so cool 😮
Is this guy going to replace Linus??, and make a new Mandella affect by saying Linus was never replace by this guy!!
Honestly, Tynan looks handsome without the beard.
Please give us a LTT vid on this were it is longer and you guys push prints to their limits.
Binder-jet printers also have that powder-is-the-support thing. So with them you can also do the just-chuck-all-the-parts-in hack (that I'm embarrassed I never thought of before).
This host is a real cutie and the 3d printer is epic as well....
Talk about a suck up, once the boss cuts his beard off he gets rid of his beard.
You know is a not linus proof when they use Premium Linus for the review
I was genuinely wondering who the new host was
Any difference between this and MJF printing? Seems really similar to each other
Well this brand didn't last long.
There should be an updated describtion, Title and a pinned comment with the information that Micronics has been acquired and cancelled the Kickstarter.
The cloning of Linus is getting freakier every time
That slicer 😱😱😱
It looks cool but it's missing a ton of features compared to Preform. They have said they will make it better though.
Tynan is doing great as a host!
please watch the : stranger parts video. The product was not so successful. He also gave it a fair review.
I would have liked info about and a comparison to FDM. What are the cons and pros?
Scotty, from Stranger Parts, also reviewed this model. He did run into quite a few big problems, and not just with the printer.
ua-cam.com/video/zmlt_FXaz1Q/v-deo.html
Not to mention VERY shady business tactics like asking him to delay the video until the Kickstarter has begun or ended *and* they demanded the printer back because they "felt their hard work was not appreciated". They also very openly told him that they want to start the Kickstarter despite all these issues because they are running out of money...
It's a cool product but how many more red flags could there possibly be...?
@@MattisProbably they wrote on their website that anyways the printers will come back because they need to come back to test and they didn't wrote it yesterday but at least 2 weeks ago
Scotty has previously advertised medical psuedoscience and represents what he got as a final review unit, which it obviously is not
The hype I have for this machine is unreal. Hobby level SLS is gonna change the game, so excited to see how the tech advances
Young Linus best Linus
Question:
Does the powder change volume when it turns into a liquid or when it changes back into a solid?.
Shrek when he turned human
And Canadian/American still not sure. Definitely 51st Stater tho.
He speaks very clearly and efficiently, you can tell ge is educated
dude has powder all over him at the end of the video... fuck this.. that shit is horrible. The PPE is extremely insufficient. You should do this in a bunny suit with a legit fitted mask. The top of the device should also have fans and filters; this should be done in a shop in an enclosed chamber with filtration, etc. This dust is not lung-friendly, will never go away, and gets everywhere.
Man I have been hoping for non industrial sls for a long time. Cant wait for it to get even cheaper
If I ever need an SLS part, I'd rather pay someone to do it. There's too much toxic dust and it's a lot of work. FDM is still my favorite. It just sits on your desk, ready to print the next part. You usually don't even have to level it, just check if the spool isn't empty and hit print. And $3,000-$4,500 is still a lot of money for some metal parts, a sheet metal case, and plastic components, and all from a company with zero experience and no track record. 🤔
Yeah, SLS will probably never end up as a consumer product. Nobody wants to wear a mask and gloves and get powder everywhere. But companies will LOVE this. And so will makerspaces.
FDM releases VOCs also
Especially if you're printing TPU or ABS.
Really no 3d printing technology is good for your lungs.
Resin of course is messy but at least because the majority of the particles are heavier than air it's more of a risk to your skin, face and eyes than your lungs.
Either way: all of them should be done in a separate room with good ventilation and PPE.
@@NerdSnipingBatman SLS is a particularly nasty process and worse - it's not intuitive why. Alongside the not-well-known risk of inhaling plastic powder there are fire and explosive hazards working with large quantities of such fine particulate. Alongside extremely disciplined PPE and ventiliation you really should be buying an explosive proof vacuum to operate this too...and those are several thousand dollars themselves.
I think companies should be able to make good use of this product but SLS is absolutely not something I'd ever recommend someone have at home. Even if it's in a separate room or garage.
Hi , this machine is definitely not production wise ready, there is a huge risk to loose several thousand dollars with this kickstarter campaign in despite the idea is very nice
I hate and love at the same time the fact that 3d printers are less of a scam compared to regular printers😂
SLS seems sooo much more useful. I've got an FDM and the fiddlyness of it really does turn it from a tool to a hobby, which may be great for some but I just want to click print and come back later and not fiddle with retraction settings or some other nonsense.
Tynan and Linus remind me of Schwatzenegger and Devito.
It works quite similar to metal printing right?
Why does clean shaved Tynan more manlier than bearded Linus? lol
I genuinely thought he was just linus in the thumbnail like usual
I'd love to see you take a look at resin printers too, just ordered a Saturn 4 Ultra from Elegoo and hoping its great, other reviewers love it, but your take on this stuff would be great
Interested when it actually hits the market, because lets face it many kickstarters promise the world and then never deliver.
so this product now no longer exists...
Linus and john Krasinski had a baby
This thing can't print any enclosed shapes, can it? I.e. if one prints a sphere, will it have powder inside its shell?
Auto tetris of pieces is really cool but you miss out on all that game time.
Thanks for a great video Tynus
