While I hope they succed, a few further concerns you havent pointed out from someone who has developed a SLS printer a few years back and is working with industrial ones on a daily basis. - Energy consumption: I think people really underestimate how much energy/costs it takes to heat a sls printer just below the melting point. The machines typically have to be preheated for 1-2 hours to have a uniform heat distribution and even for a small machine like this that would probably mean 2 - 3 kw/h, without even starting the print. So this means printing just 3-4 parts as the home user typically does is kinda expensive. - Maintenance: These machines have to be thoroughly cleaned before every print. Not only does the powder spill everywhere, the fumes from the process settle down everywhere and have to be constantly removed. Warping/shrinkage: There is a reason you most of the time only see rather small parts on those exhibitions. For lager parts you have to compensate for shinkage in all dimensions and futhermore the shinkage/deformation may vary on every point in the chamber as the parts cool down diffrently in regards to their position.

There's a minimum powder required to get started(fill the build chamber) and then the efficiency of the power usage. Assuming every print job you complete has a print density of greater than 30%, theoretically you get 1kg of parts from 1kg of powder forever. The reality is that about 3-8% of the powder goes to waste with each print job. That's through poor initial cleaning(more powder sandblasted off instead of being recycled) and spillage(there will always be some mess moving stuff around) Judging by the size of the build volume, I'm going to guess around 3kg for a full build volume. The Fuse 1 and Fuse 1+ build chamber requires about 7Kg for a full build volume.

There's no point buying a printer if your usage for the entire lifetime of the printer is only a kilogram's worth of prints.

We bought a Formlabs fuse SLS machine at work. At first we were like OMG NO SUPPORTS NEEDED then you spend 1h cleaning the parts and understand that if it doesn't need support it's because the cake is really tought. Then you spend more time cleaning everything and if you don't have an antistatic vacuum cleaner be careful to not be jolted by static discharges. But yes the parts are great! Selling this machine at this price is a feat in itself, but selling it for "enthusiasts" is a bit optimistic. Once you dealt with the hassle of post-processing a SLS part, you do realise that many parts are best produced on a cheaper FDM machine that doesn't need a special vacuum cleaner and a sandblasting machine on top of that. It will fit well for small companies, educational institutions, and some "heavy enthusiasts". Let's hope that it will force other actors to take a better look at their pricing, too!

If you are talking about microplastics, we just do not have enough research to have any significant data about the dangers posed by microplastics. No matter what, it is minimal compared to things like aerosolized coal dust, asbestos, heavy metals, and radioisotopes. All of which, in the west, we exposed ourselves to at insanely higher levels than we do now. For all of the aforementioned environment pollutants, the moment we started studying them with any seriousness it was crystal clear that they had pronounced negative effects on health. Microplastics are and have been studied for quite some time, so if they are harmful, the harm posed is very small by comparison. Most of the studies that I have seen that actually show harm have exposure levels that are exponentially higher than anything that people are coming into contact with. So, instead of terming it a 'very heavy environment problem that is not being talked about,' I would say it is likely a smaller environmental concern that is being researched at an acceptable rate. We live in a world where a shocking number of people are morbidly obese, huge numbers have metabolic disease, we have increasing rates of dementia and other neurological conditions with very significant metabolic components, and the average westerner is lethargic and eats a diet that is shockingly high in ultra processed foods (between 57% and 73% of the American diet in studies I am familiar with, by calories consumed). Yet I hear more about the dangers of things like microplastics than I do diet, lack of exercise, and shockingly high levels of outdoor particulate air pollution in the developing world.

The 3D Printing content on youtube draws FAR too many 'safety' concerns. Nylon is literally used in just about every implantable medical device, because it is just about as inert as a material can be. Nearly anything you could come into contact with, in any fabrication environment, is more harmful. Breathing tons of dust particles is bad no matter what they are made from, so use a p100 or N95 mask while handling the powder and you are protected. They look like they do dust control well in addition. You need to media blast the objects, and chances are if you have a media blaster, you know to not breathe in all the aerosolized blast media that is far worse than nylon. If not, there is no fixing stupid. Either way, do your thing, let any dust settle, and keep a clean workspace. The human body is insanely resilient to small exposures to tons of things that are harmful in huge doses. In nearly every case, we find that exposures at reasonable levels have no measurable effect on health or longevity. This is true for everything from VOCs and fine particulates, to ionizing radiation. Until you exceed a reasonable exposure limit, we have identified zero harms. For substances where this is less true (where the acceptable limits are very low) like asbestos, heavy metals, etc., we basically have banned any application where meaningful exposure is even possible. The excess 'safety' concern in 3D printing KZitem content has annoyed me for a while. The Q1 pro reviews that mentioned that the chamber heater could be dangerous if you stuck a conductor through the heater shield while the printer was in operation were too much. This is true. I can also think of about 1000 other ways you could get hurt doing equally stupid things with consumer equipment. 3D printers are tools and probably the tools most tolerant of user stupidity. But yet the KZitem 3D printing channels act like anything that isn't 100% tolerant of user stupidity is a huge safety concern. It is like folks complaining about the electric shock hazard of US plugs. It exists, sure, and yet if you eliminated it completely, you wouldn't have a noticeable effect on US all-cause mortality. Safety has to be a likelihood vs danger vs benefit analysis. Folks who can't do that analysis, should learn how to or stay away from anything more dangerous than baby toys. We all drive for heaven's sake.

So as a Fuse1 owner, that powder cleaning setup is absolutely not going to be sufficient. ;-) Even with Formlabs' Sift cleaning station (with a giant filter and suction system) powder *still* sneaks out everywhere just at every step once it's out of the printer... Doing that kind of cleaning in an open container as shown will be a HUGE mess after a couple prints. (Especially since you need to brush the partially sintered powder somewhat aggressively-- it doesn't just fall away loose like with MultiJet Fusion or EOS powders.) I'm also a little skeptical of the claims for supporting PA+CF powder as I believe that would really require an inert atmosphere in the machine. I can see a lot of print problems in their sample parts (possibly just from powder that was reused too many times or with too low of refresh rate), but for an entire printer that costs about as much as just the build chamber for the Fuse1... Might be worth a shot!

Packing the build volume is actually rather complex if you're looking for dimensional accuracy. Parts too close together can cause "creep" of the heat and make the melted areas creep towards each other. For real precision you also want the laser scan time per layer to be rather uniform, which helps maintain uniform temperature deformation. Lastly, for very fine details you still need to take into account the wavelength of the laser. Prime example is small holes, where even a single pass may cause enough creep to close the hole.

It’s not entirely true though once you dig a little deeper. Prints can fail and the more complex they are the more likely they will be to fail. When just looking at one off items and not considering any failures then complexity is free. Also post processing is more complex for complex models and hence takes longer, again complexity is not free. SLS parts needing media blasted is a good example of this, the more complex the model the harder it will be to post process, especially if you have print in place mechanisms that you need to find a way to get the powder out of. Looking at other forms of 3D printing complexity is also not free when you have to add supports to support your complex models, especially when you get that complex that you have to use dissolvable supports. So complexity being free is not true, it can cost more in terms of time or money, it is however much cheaper than other manufacturing processes which may not even be able to produce your part.

I have serious doubts about the safety of this machine in the hands of "typical" end users. An N95 mask really isn't enough. This machine needs to be limited to enclosed spaces away from living spaces, because there IS going to be dust getting everywhere, and despite nylon being non-toxic, the fine particulate itself poses a physical risk to your lungs. Hopefully with future iterations this can be better addressed. I also hope that they have done their research on manufacturing. There is no doubt that in order to get the machines manufactured to sell at this price point, they will be using a Chinese factory, and manufacturing in China comes with a lot of caveats. Most factories over there will make undocumented changes to your parts if you don't stand over them micromanaging everything, and this can have pretty serious results. It really is necessary to have someone in the factory working directly for you, not the factory ensuring that quality is maintained and there are no changes being made to your specification.

That glass cantilever screen needs to have plastic laminated to it so when it pops it doesn’t ruin your powder or cause injury . I worked with pinball machines and when pulling out the glass it had to be supported, if you didn’t the cantilever would stress tempered glass to much and you would get an explosion. I saw 3 pinballs ruined from careless service guys or arcade staff when cleaning the glass and moving a jammed ball.

One accidental advantage of FDM is you get your polymer chains lined up as the model is built. Obviously not isotropic, yet I bet it's stronger along the extrusion paths than something fused from a fine powder. Would be nice to see a bench test tho, maybe I'm wrong. For now I'm quite happy with how my tactically positioned parts work together to make really resilient mechanisms, pretty close to what you would expect with injection molding. Metal SLS sounds more sensible, there you don't rely on larger molecular structures, as long as the powder fuses properly, it can be as good or even better than cast parts.

As you say FDM can be very strong if the parts are designed for FDM printing with the best possible print orientation.

Adding the post processing (you can't batch process the blasting part), the printed parts will be a lot more expensive.

On the side, SLS is also a very confusing name. There's nothing to do with sintering in a plastics process. Sintering in a single media system sintering is an entirely solid phase process. SLS is also just melting. To be fair, I don't wanna use the ISO names either (PBF-LB/M instead of SLS). Furthermore, the preheating thing in the video is claimed to be something special. It's not. All SLS works like that, that's the entire reason you don't need supports. Because the temperature differences are minimal and the thermal gradient is small. Compare that to SLM, where the temp difference is above 1000K and the gradient enters the million K per s range. That's the major difference between SLS and SLM. The reason those machines are cheap is because they don't use laser optics but basically a laser mounted to a basic 3d printer. That's not something horrible but I felt the need to point out that speeds will be much lower due to that. Credibility? I literally study this at University

I own a Sintratec SLS kit for 5K USD/EUR. The biggest issue is closed software code or microcontroller hardware. it's really off-putting when you can fix or tweak the process, especially on something delivered as a kit. The worst aspect of SLS is the non-uniform pre-heating of the powder. Any reflection of the IR halogen bulbs on the chamber walls does lead to spot being hotter than others. Some areas will melt and clog up the slider distributing the powder ruining your prints in progress. other areas will not get hot enough to properly melt and solidify. not bond properly. Also, fine tuning of the unused material not caking up gets hard, ramping up excessive deterioration of the powder. You would need to access the sensor reads and tweak them in code, both of the slicer and the microcontroller level. Which you cannot do if it's not fully open source. in the case of my Sintratec kit it isn't, so I would have to design a board and software from scratch. I resorted to black super high heat resistant paint to cover the chamber walls and reduce reflections. However this interferes with the powder slider operations and the microswitches controlling the endstop positions, as these are not heat resitant enough. It's tricky to find and source better reliable heat resistant switches or come up with simple solutions. In the end of it I use other techniques than SLS and still do most prints on a single extruder FDM Ender 6 machine. I only needed a set of a dozen small hydrodynamic surfaces FDM could do from that machine. Eventually using a second FDM machine with a dual extruder would be the better option. The only advantage of any truly open source SLS machione would be the functional parts nylon PA12 can achieve. In FDM this si the realm of carbon fibre enhanced filaments and Sinter metal FDM filaments used in conjunction with washable support materials. The powder cost and especially the powder waste is exceptionally high. Actually without very delicate tweaking all the powder in the chamber is lost once exposed to to the IR light heating process. I would tend say more laser power in the 15 W range is better as you do not have to preheat uniformly very close to the melting point. 5 W isn't really does enough for getting the job done properly. Light reflections in the build chamber do cause way too much uneven heating of the thin top layer of powder. Throwing multiple parts into the chamber isn't such a great idea either. Many parts will warp and any of them might cause a failed print. it's near impossible, even from recorded video footage, to discern which print largely submerged did cause the slider to crash into such a warped part or dislocated part. So maximizing your build chamber utilization is really workable either unless you have super good heat mangement and can tweak it in open source accessible stuff. On the other hand providers don't want to be liable for you tweaking high power laser gear. So very likely the stuff you need to get at is locked down. Also working with lasers is highly dangerous. For me it's just a few burned rubber gloves so far, even when being super cautious. You don't see laser light path. Also the Sintratec machine needs mirror cleaning and significantly had to improve ventilation flow and filtering to make it work more reliably. The Micronics filter system looks more serious but I would have to look at the specific machine before deciding to buy / not buy one. As modifying filters would impact the exposure timing, heat management and heat tuning I would also insist on a fully open source accessible platform in both software slicer suite as well as in microcontroller access you are no likely to get here. Managing poweder as a desktop printer is impossible. This is only suitable for dusty workshops. I use a cyklone filter on a shopvac. Then build a powder sieve for recycling powder from a 100 micorn lab sieve, ikea boxes a few springs and an old swing grinder. Only to be used outddors. I also build myself a sandblasting chamber and bought a compressor. The need for accessories is high and needs to be factiored into the price. I would skip on the their sieve and directly sandblast the cake recovered from the chamber. Sieve the excess powder after. keep in mind it is questionable if you can reuse it after heating. Again, you would only get a working powder economy if you have full access to the source code of the temperature management. Also posititioning and access to the IT sensor signal is key. Huge difference if that IR sensor scopes black melted or grey unmelted plastics in the previous layer. Another thing you want access to understand what the machine is failing at. Stuff likely not exposed by any closed shop software you may be ending up to being to tied to for good or bad. I hope this gives you a much better SLS insider idea what you are betting 3k plus bucks onto.

They missed a market with this printer with 30% trash rate, and $80/kg. The printer should be alot smaller, especially if made for hobbyist. This would be a good printer to make small parts FDM couldn't make and attach them to bigger FDM prints.

Using Kickstarter "as it was intended" is absolutely doomed. I don't know how many people gave small support pledges vs "get the product" pledges. But fundamentally they haven't layed out to us their plan for budgeting RnD and production. And it's pretty much impossible to produce the machines once the money is spent on actually making them work/manufacturable/shippable. So assuming they actually haven't even drafted a full plan yet... They need "real" investment help, not vouchers to send machine they could take massive losses on.

It's really ingenius in many ways, even if there are some hiccups. The slicer especially. Just needs some more thought to post processing, such as recycling used nylon powder. Post processing SLS prints is a major hassle in my experience. At least without something like you get with the Formlabs Fuse 1 setup (downdraft table, vacuum, air blaster, etc).

So and how much does a kilo of that "powder" cost ? :P (ah 6 kilo is only $599,-) And heating that stuff while printing. don't know how long that take, do know 1 halogen is 1200w (at 220v)

As someone who uses a Formlabs Fuse and Fuse 1+ at work, I don't think the technology is appropriate for household use. I've had employees not take the respiratory health risks seriously and wind up with lasting headaches and weight loss(not the good kind). The waste is difficult to dispose of, and its recommended that you use a static dissipative vacuum system because the dust can be explosive under some circumstances. The build volume is frustratingly small after coming from FMD printers. Post processing is messy and requires a dedicated separate area for blasting in order to prevent contamination of your materials. FDM is much more home gamer friendly.
