To a 100% capitalist pig, every normal person who doesnt support him is a communist.

That crunchy 8 bit intro music is bad, lol.

So weird YT algo just decided to show me this video after a year. For the person who have been born in USSR and lived portion of the life thru USSR legacy it's so stupid to hear someone playing "Communist" card to Justify practically "invalid" patent... Slice got hammered with defending this patent once with Voron Community when Dragon was released and now they are definitely buying a good faith by throwing Vez under the bus - THE guy who have showed the world how cool fast 3D printing can be... nice choice...

As others have said ethanol seems to dissolve the PVOH much better than IPA. In the US hardware stores usually sell denatured (methanol added) ethanol as a lacquer solvent.

My PVOH simply won't dissolve no matter what I try, heating from cold, adding a drop of ethanol, even NaOH as suggested on the internet, just becomes a sticky mess at the bottom... What specifically did you buy?

It's so dumb to me like why on earth would this be patentable in the first place? It's literally screws/struts acting as structural reinforcement. This is pillars people. Pillars are thousands of years old tech...geez.

Changed careers and stopped following 3dp news for a bit, so I've been wondering about the vz/slice kerfuffle since I got back into it a couple weeks ago. Thanks for enlightening us about the situation! Outdated response to old news, I know... When I was building my voron 2.4, I was doing it on a minimalist budget. I ended up going with a dragon, but learned about slice and their products while researching what components I wanted in my machine. Then - as I am now - I was VERY impressed with the concepts and quality they brought to market. At that time, I intended to invest in their products for upgrades when my budget supported it. Fast forward a few months, and the tone deaf nature of their communications, holier then thou attitude, and hardline stance on perceived injustices back when they came after the dragon (understandable) and the small 3dprinting resellers (less palatable) in the US ruined their reputation for me. I continue to respect their contributions, but choose to vote with my wallet and refuse to support them as a business. I consider them to operate similar to sawstop - a company with potentially great ideas operated in a manner I won't condone and won't support financially - taking advantage of the patent system in ways that I consider to be unfair practices with overly broad patents paired with overzealous defense of those patents, especially when there are numerous examples available publicly preceding the patent by years. And after being a self righteous duche in explaining how you're the one being harmed, it airways feels like a super republican American-politics-style move trying to distract from the message by talking about donations. If you're going to be an a-hole, don't hide behind Sanjay and veterans. As a veteran, I do not approve of your tactics and I don't want to be your shield - and am even less inclined to give you my money. It plays back into their systemic inability to control their own message - get emotional writing the press release, choose not soften your message enough, try to walk back the sting at the end with a little mild deflection. Honestly, the good they're doing is commendable, butrelease a different dedicated statement about how much good you're doing, don't try to temper the outrage you know your statement will induce by adding a blurb at the end to pander to the community and deflect from the actual message.

Galeaf is the most interesting thing to happen in this market lately. If there is a way to circumvent this bureaucracy, users will gladly support the VZ BOT team. They make a really cool product. Slice have earned themselves a reputation as assholes in a market where there are plenty of options to do without them.

I had no idea slice engineering were such freaks. From now on, I'll buy anything but their product.

I dont understand, why 4 extra screws make a big difference? They still transfer heat upward, right?

Slice could EASILY quash the controversy in one day. They could blame the C&D on "legal department" doing what they just do outside the awareness of Slice ownership, which is probably true anyway, then license the "incredibly awesome innovation" of four post mount to Vez for a token amount, like a dollar or $1000 or whatever, and drive on. This would demonstrate that they indeed believe in the benefits of human innovation Of course their pithy ridiculous letter is another matter, but they could simply explain it was an emotional reaction, which is probably also true anyway. I mean OK, in "Reasonable World" we like free markets. On one extreme you can lean toward communist utopia and the other extreme is called facism. In my opinion, current patent system is broken and enables facist leanings. Patents should only be allowed to last 3 years or 5 years or something. Get an idea, flood the market with it and make your mark while you can, then continue stacking innovations so your business can survive. Alas, that's my personal pipe dream. Anyway, Slice could do damage control and fix this easily if they chose to do so. They've laid the groundwork by claiming that they don't enforce bimetal heat breaks. Then do a solid for the 3D print community and support innovations. Their choice whether to or not will demonstrate whether they are facist bullies. OK yeah, legal yada yada. Obviously the actual problem for them is past that and about something else now. Something more important and more valid in my opinion. Goliath is fairly unique other than the four legs. Maybe Vez can simply make it 5 or something?

hoho

I ve necer and will never buy a slice engineering product

where are those tests ;)

Patents are so stupid. Stifling innovation and progress

It may have been a stretch bringing Apple into this conversation. They are only known for proprietary technology, and will go as far as going after their own customer base to protect their IP.

Slice engineering will never see any of my money

🤣 they don't care about introducing new and better hotends. They don't want open source

What till they figure out how air cooled engines are put together

Can I use this one in standalone mode

the fact that they even got the patent in the first place is a mystery, and just goes to show how much of a joke the american patent office and courts are. there's been hotends with screws as spacers long before slice engineering was even a thing.

THANK YOU I FEEL INSULTED BY SLICE AND WILL NOT BUY ANY OF THEIR PRODUCTS

slice are just a bunch of trolls. They're good for nothing.

Their handling of parents is bad enough but that paired with their released statement has assured I'll never buy one of their products.

Taking stuff from the community? Of course! Giving back? Of course not! Fuck these greedy asses.

Open source is for people with a principle, patents are for people why want to make more money by sniffling competition instead of bolstering cooperation.

Dear Slice, If you want to beat another company, BE BETTER THAN THEM! I own MULTPILE - AND *EXPENSIVE* Slice hotends. I HIGHLY doubt Vez will bankrupt you guys. I would stand down and let this go, if I were you. BTW, can't "prior art" get a patent revoked? Great arguments here, Jonas! BTW, New sub.

Im just now finding out about this. It's a shame too, I was going to use one of their hotends in my upcoming voron build and I was considering strapping one to my ender too. I'm glad I saw this before I pulled the trigger.

Yeah except Prusa isn't actually open source. They hide behind that label while gobbling up and shutting down any real innovation in the 3D printing space. Prusa hasn't been relevant in almost a decade but still has the balls to charge people ~1k for an upgraded freaking Mendel in 2024. The XL is the ONLY interesting thing they've made in a decade and even that is just an evolution on the E3D toolchanger. Plus Josef Prusa is such a fucking narcissist toolbag. I decided to take a look at Prusament the other day and "MADE PERSONALLY BY JOSEF PRUSA" (or something extremely close to that) is plastered on each product page in giant letters. Fucking really dude? You had as much to do with producing Prusament as Elon Musk does with producing his rockets. While I love the open source community and ethos I don't think patents are inherently evil. Slice's patent, however, is invalid in my eyes and should never have been issued. Wow they changed the standoff design from 1 to 4? aMaZiNg! This one act/situation ensures I'll never give Slice a cent of my money; no matter how much I want to try their plastic repellent paint.

Yeah I'm about as libertarian as anyone, and as anyone that isn't currently ODing on copium will tell you, that means very definitively not communist, but "we added spacers to stop hot thing from touching cold thing" isn't patentable 'technology'; it's adding fucking spacers. "How do I stop the hot thing from making the cold thing hot? Oh, I know, I'll just not let them touch" "you can't do that, I invented that technology, I own it" You didn't invent not letting a hot thing touch a cold thing, I mean WTF? 3:45 literally the entirety of linux would like to have a word with that graph

slice engineering customer service sucks as well. I'm done supporting greedy companies.

I refuse to backup patents. If we want to grow our knowledge as a species, we need to innovate and tweak. The lightbulb was not the invention of one man alone, it came frome that man that made glass, electricity, wire. It came from the man who decided to have gas lit homes, it came from everyone before who created the base idea and it was tweaked and improved until today, we are much farther than we could have immagined because multiple people saw a problem, 1 fixed theirs, letting the next fix theirs and so on. Locking this down is greed. If you want to sell a product, make a good product, if someone makes a worse product that looks like yours but has their name on it, looks beter for you, to sell a product then make a good damn product. Dont say "i dont allow you to make a better product than me" and claim that its all to HELP innovation. It is backwards and unfortunately while i have always loved the mosquito hotend. I actually never intend to give slice a dime of my money and ill look elsewhere....

I don't agree with slice response, but to be honest I don't agree with yours either. Patents are not evil, they protect a company from copies so it can recoup its research investment. Yes Prusa succeeded without patents, but they got into market the right time and started from a country with low manufacturing cost. Patents in injection moulding don't expire fast, all patents last 20 years. Bimetal was not patented probably because it wasn't slice engineering's idea. Their patent is unique because they are using hollow spacers with screws in the middle. I am sure people have used those before but the patent office does not look for prior art online (yes, this is wrong ) only in other patents. The Buda-style hotend A and B posted in RepRap forums does not use hollow tubes as standoffs so it wouldn't be prior art anyway. The heating element around the goliath extruder is similar to Dyzedesign Typhoon which is similar to what you will find is some injection moulding machines. The comments about communism are nonsense, even communist countries had a patent system, however Slice is right to try and defend against hot ends with tubular standoffs. The big issue in 3D printing is that the patent office doesn't search online. As a result a few companies have patented other people's ideas posted online.

But remember, if you don't want the government to enforce a monopoly on the ability to make products, you just want communism, apparently.

Such an American thing to sue people who want to innovate. Heck, they would patent turds so everyone has to pay every time we take a dump ... ha ha ha. Fk slice.

The statement is just stupid af. I dont even bother with a company thats so unprofessional.

This is awesome and I can't wait to try it! One question though - I gotta be missing something stupid but can someone ELI5 how 10g:2g is a 70:30 mix? What am I missing here as far as how this calculation works?

After reading the patent, I think if we don't use spacer made of stainless steel, zirconia or any combination of the two, we're not infringing the patent. Titanium will be okey like they do right now.

It’s 3 pins not 4? Or maybe there thing is actually a copy. Patents basically invent creative ways to work around. Just pay first for a patent for your thing as they typically don’t even check if it infringes.. I‘d guess if they could have patented bi metal they would have. Should be as simple as making a round object that holds the sides. Patents are from my side seen a unfair advantage in a free market as its monopolizing the space.

great video! I am working on a different method of decoupling. I will publish everything in some open format, and would be more than hapyp to slam the door for slice and their funny little patent. i love the bimetal principle, but always disliked simply bolting on the hotend. theres another way, but it has to be very sturdy - which is the hard part. but it is possible, in my opinion. slice is not the best thing ever, even if was close - for its time.... today, VZBOT smokes them, by a mile, and they know it. seems like the mosquito was all they really got.

In 2019 Toyota released nearly 24,000 of its patents for royalty-free use, including patents for its modern electric and hybrid vehicle technology. 24000! Do you hear this Slice Engineering?

Thanks for making this video, i was about to buy the Slice Mosquito and saw the Goliath on Aliexpress, I was torn between the 2 and after watching this, I'll be going with @Vez3d and buy the Goliath.

The best way to fuck your whole company over is to mess with the big and loved creators within the community that makes up most of your customers. This statement cost them way more customers than the Goliath hotned ever will…
