what do you think of a claim of having a process that can be used for 3D printing process, a method that allows generating material that normally takes 10s of thousands of watt hours, and has no shape control, to finished sections (controllable locations) in half watt micro-seconds of energy per section? I ask because I actually have stumbled on something due to my path I have been following for developing replicator level 3D printer upgrades, that allows me to make diTitanium Trioxide (a brownish-black solid semiconductor crystal material,) out of titanium dioxide powder (never mind the lack of additional titanium metal powder to offset the balance of titanium and oxygen, nor a controlled atmosphere) by testing a 500mW 405nm UV laser diode. (plan is to use this for other materials I can make custom pathways for fluid bed catalytic reformers first before even approaching actual attempt at incorporating it into an array of tooling for 3D printing.) mind you I could do a little video that would not be very impressive but would show the process working all with out any CGI or touchup nonsense like they are using in the kickstarter video you are showing here LOL.
Thank you for the review! Loved your ending. FYI, think I figured out the "5 color vs. 7 color" issue you mention in minutes 12 and 13: the base printer comes with 2 colors. So the added 5 color tower, makes the total of 7. (You seem to have figured it out in minute 17. :) ) God bless in Jesus name.
Reflecting on your introduction…. Was 50k the cost of producing the video ads that they made?!? 🧐 was everything else earned ‘gravy’ on top…. You’re raising the alarm on this is a great service to the community, if for nothing else you’re clearly articulating what NOT to do for ANY campaign legitimate or not. ❤
The color tower can fit 5 spools and the printer itself can fit 2 spools on the bottom. But ya I’m curious how the filament change is being done. It seems like they will have an extruder motor for each color?
I don't think any of the competing AI modeling systems are open source yet, so they're probably waiting for one. As far as 3D scanning, it looks like they're doing photogrammetry instead, which is 3D reconstruction, not 3D scanning. I'm surprised that people are backing this without any actual demonstrations, but yes, I hope for the best for those who've supported the project and the industry as a whole.
Speaking from recent experience: I don't want "AI badly guessing" at my choices. I prefer exactness in my technology. That reminds me, I should stop paying OpenAI before the next month rolls over! It wrote a bunch of Rust for me that wouldn't compile. What a waste of money. Well, not a waste as I learned something, and it was only $40. What a time to be alive! :)
I feel like the 21m/s sqr and 5 material hub are delibarate "one ups" on the X1C's 20m/s sqr and 4 material hub. Even the "cheaper model without enclosure" feels like it was inspired by the P1P
if the bambu lab kickstarter taught us anything, its that it's 100% worth paying full price for the 4th or 5th revision of the machine months after the KS models have shipped
Comparing this Kickstarter to the one for Bambu lab is like comparing apples and oranges. With the X1C we saw reviewers testing actual units. I took a calculated risk; my KS X1C with AMS has exceeded my expectations.
Not really sure that's a meaningful takeaway from that kickstarter campaign, it was extremely successful and almost every printer I've kept track of has performed well - including mine.
This is why I missed the BambuX1 kickstarter. I had been burned in the past, and have sworn off of Kickstarter at least for 3D printers. I do have a X1 and a P1P, but glad I waited until I could see reviews
Thanks for this! I got an email about this kickstarter several weeks ago & was considering it as my first printer. I had concerns as the project page and videos seemed to be light on what this printer can do and was more focused on the "idea of having a 3d printer". After watching the 2 videos you made and another by someone else, I think I'll pass on this for now and look for one that has a proven track record.
So I don't do kickstarters but it seems the new thing there is to set you goal low so it's easy to exceed. Does this mean they get the money, whether the product exist or not?
The issue with kickstarters usually doesn't come with the product itself. Production and distribution are difficult to pull off at best. I kinda doubt they can get manufacturing up in the 2 months between the end of the kickstarter and when they claim to be shipping it.
Technically is more stable due to lower centre of gravity, less vibrations and make it more stable so fast 3D printing is more reliable , that was all of the benefits that i can remember
The 7 color thing is slightly misleading because they mention it can load a two-color filament (I am not sure what that is, gonna ask them) and the additional 5-color tower, so 6 spools in total. It seems like an ok buy if they can nail the closed-loop motors, radar, and camera, for $600, and if it is indeed an inverted CoreXY with a PEI bed or equivalent.
@@3dpprofessor Found their comment, it's a translation error, it seems like the printer itself has a one nozzle dual extruder design and holds two spools already, though a purge tower is necessary when changing the filament. I'll look at more information regarding how the filament tower works.
Well, I updated the app, and the 3D avatar doesn't work any better, it still just maps a picture of my face on the 3D model of someone else's. The update notes say the 3D scanning portion has opened up, but when I tried to use it it still wouldn't let me upload any images. So I uninstalled and reinstalled the app, and now I can't log in.
I see you have a spool of Polymaker behind you. My favorite filament. Love their PolyTerra. All this hype on multi-color printing or printing with different types of filament, I would get an IDEX printer instead. Granted that means 2 colors or 2 types but I do not like one module with multiple hot ends and nozzles in that one unit. Plus the IDEX can mirror a model or duplicate it. Super fast print speeds "for prototyping" is very useful and the sacrifice of definition is acceptable. I have a LulzBot TAZ 5 where I built a Moarstruder with a 1.2mm nozzle using 2.85mm filament. I can print 4 times faster, I could potentially push it even faster if I bypass the recommendations. The quality and definition is definitely of prototype quality but that is exactly the purpose. I can push my printers, I have 10 of them, to higher speeds vs. the CURA defaults but I really haven't as I don't need faster prints with less definition plus I use the TAZ for that. I did try to push my Snapmaker A350 to a 150mm/s speed and it printed a "fair" benchy and layer shifted. Now I did not study as to why it layer shifted. I don't believe my build plate moved and how could the tool head have moved. I might try it again and see why/how it happened. Or I could see what the quality is at 100mm/s. Before I would risk a kickstarter, I did not buy my Snapmaker on a kickstarter, but before I did I would need to see some reviews of a printer in your hands and other reviewers hands. Or, at least companies like Ankermake have been in manufacturing for a long enough time with enough products to give us confidence. Nice video as always, thanks.
Your analysis of acceleration is a bit off. If they could actually do it (they can't/won't because they don't know anything about making printers), 21k is really useful despite not having seconds over which to do that. Roughly you want acceleration at least numerically equal to the square of your target velocity (reaching full command speed in 0.5 mm).
I backed it yesterday... About the 7 colour printing... 2 rolls are in the base. 5 are in the tower. Look it up in the FAQ. Under the point "which filaments are supported?"
I would think so, but maybe it just flings it out of the way. Again, I'd love to try one out, but they decided launching a half-baked kickstarter was more important than showing their machine in action.
I am thinking I have seen this design somewhere else but cant remember where! and I have just realised it is the upside down printing I have seen before by Kraylyn 3D, this was an awesome design that unfortunately did not reach its target but was a genuine design by an extremly clever guy. This all seems very sketchy, I dont take part in Kickstarter things as I consider it as gambling and I dont gamble or give in to getting something for nothing or cheaper as these are the tools of the con merchant, if this thing comes to market and was something I wanted I would be happy to pay the full price.
@@3dpprofessor Especially when you consider the Bambu Lab machines can be purchased right now and have the capability of 16 colours and all their features are real!
i'm all for being sceptical but you missed a basic function of the main unit bein 2 colour 2+5=7. loses you a lot weight to your words when you miss simple basics
@@hightechjoe1 Sure. But until we see that they have an actual working prototype, especially in the hands on unbiased reviewers, it's all just words on the screen. It's all just what they *want* to do. Buzzwords and promises is all this campaign has offered so far.
I certainly think they are exaggerating the printer's capabilities. Considering they are marketing to novices and enthusiasts, it will be a huge disappointment. First off, while FDM printing upside down is possible, it's really not practical. Sure, it looks cool. However, when I have a failed print due to an adhesion issue, I'll get spaghetti on my current printers. By upside-down printing, it will probably be a blob of death every time. Fundamentally, I don't see the value in their printer even if they can deliver on all of their claimed features.
Part of your discussion of unloading and loading back has been tried. I've tried to do it on different machines with specialized hardware it's very unreliable. Consider what happens when you retract, you create a little bulge at the end of the filament. A lot of projects have tried to retract and shape the filament on the way out of the cold end, retract in steps to have it shaped so that it can re-inserted back into the hotend and not jam, it's been tried over and over again, even using special forming heatbreaks, IT DOESNT work, at least not how you need it to work so that you can expect thousands of filament changes and trust it. Best I've seen is 90% reliability and that already means you get a jam within minutes of starting a multi- color print.
Did I not mention the bulb in this take? Darn it, I didn't mention it in this take. In an earlier recording that I threw out for being too long I mentioned what you did, about the bulge. Bambu, instead of dealing with that, chose to cut the filament above the heat break, but the result is they purge a lot. This one can't purge that much, so they've got to unload completely, and as you say, that creates problems. Problems that I don't know if they can sort out in 3 months when they promise delivery.
Greetings! Thank you for your comments! You are clearly an expert in the field of 3D printing. You are correct that unloading and reloading the filament can cause issues if the hardware is not designed appropriately or make proper modifications, such as the problem of filament bulging and potential jamming. We have dedicated countless hours to addressing these issues by designing specific mechanical structures and flow control approaches that eliminate filament bulging and other potential issues. As a result, our mass-produced KOKONI SOTA units now feature reliable color-changing approaches. Stay tuned for further updates!
Bambu has 20K accel, so 21K for something this small isn't that special. "The 100" printer even has 100K accel. I also didn't see an actual max. speed mentioned. So far this sounds like baked air ...
@@projecthivemind3239 That's not how it works. You have to integrate to get x=a×t²/2 (after solving v=a×t to find where it reaches cruise and stops accelerating). I'm getting 8.232 mm.
@@daliasprints9798 Indeed and then you have jerk or PA settings influencing what happens when you reach the end of a straight movement. Bottom-line is that the lack of details on how exactly their motion system tries to achieve what they claim and how they counter the issues that fast motion brings (PA, input shaping, lighter print-head, super cooling power, more heat transfer in the nozzle, ...) makes it likely that whatever they deliver will be nowhere close to the wonders a Voron or Bambulab deliver. Also on multi-color: the cutter of the Bambulab is there for a reason - reduce the risk of clogging due to heat-creep. Retracting fully might slightly lower the amount of purging, but at the cost of way higher risk of clogging.
And here's another thought, if it can almost instantly get about the print-space wouldn't it become a safety issue selling it without a cover? Fast enough to mangle a hand or something. Wouldn't want that near small kids for sure. And yes, I thought this was a bit fishy too.
I signed up for the combo, I got already 6 other 3d printers so it will for sure be interresting to see how the 7 colour printing works for this printer compared to my Bambu Labs X1C, the Snapmaker J1 and sooooon the Prusa XL with 5 tool heads...
With how much this is on facebook ads, they have 100% spend more on marketing than product development. They went to CES, but are using kickstarter? Yeah no. 100% a scam. They may have a prototype, but there is 0 chance they have a functioning product.
It's a copy of the positron. When you point that out they deny it and claim they invented everything from scratch as their own original ideas. Naomi Wu already recently had interaction with these folks, she said to stay away.
Again with the crazy claims of 10-12x faster. A box stock Prusa MK3S+ with default settings adjusted to the speed boat settings does it in just over an hour. 20 minutes isn't 10x faster than an hour. Also of note, that machine was shaking quite a bit during that print. They also use low quality footage and never show a close up, but it's pretty obvious that print is ROUGH. The most worrying thing is that the printer is obviously still in development as the 20 minute benchy video has a MASSIVE extruder assembly compared to all the other videos, and that's going to eat up a lot of Z travel. Prove me wrong, but I'm not giving them money for a product that is still in active development.
Thanks for pointing out to people the possible flaws. I really don't know what people would back this? Why would people who know about 3d printers not see the dodginess of this ie we've all seen photogrammetry fail whenever it's used. So why would this not? Upside-down printing, it just seems any benefits are far outweighed by prints falling off. Why would beginners buy a printer on Kickstarter when they're are hundreds of printers already out there working fine? At £500 I cant see why people are backing it like lemmings. There does seem to be this video of a reviewer with one on youtube watch?v=lLPJvChIwpU
@@3dpprofessor People did comment his video was a bit biased and wondered why he had been sent out over other proper 3D printer UA-camrs. His channel does say he's in Shengen China.
I paid to support SprayPrinter, but as they dragged time on, they said they wont ship the devices because they said they wanted to make a more accurate version of a software interface, even though they already had one that was shown to work reasonably good enough. Their 2nd last video was them showing one of the development team being shoved into a drum and sealed in there like a hostage, all hollywood production-like. Their last one was of them standing around in another parkinglot scene with some walking coke spoon of a telsa investor who they claim convinced them to not release the product until they got more organized, and after that, no more uploads from them ever again. Really pissed off alot of crowdfunders..and the devices were said to have been already made and able to ship to their prepaying customers. I followed up over a year or so after to find out whats going on, because I saw one of their new version2 multicolor SprayPrinters actually owned and being used by an artist in the same country overseas that SprayPrinter is from. I said to the artist on his youtube page a compliment of his nice wall mural that he created with it, and he replied back saying thanx. Following up invovled the owner flat out lying about who his name was, as he chose to use a fake name that I noticed was being used in another one of his uploaded content examples as he was participating in some text based forum type website while i researched the tracks that sprayprinter CEO left like easy to find crumbs on a path in the woods for detection, inadvertently. He replied back to me with that fake name saying about feeling bad about it, which only pissed me off further due to the obvious boldfaced lying manipulative tactic, but I have yet to produce a documentary or encourage others to expose their flaky scam. The really did seem legit at first, but they pissed away all the crowdfunded money on a whirlwind vacation in the sun, while taking the time to make an appearance at a big 3d printing event, yet they were not invited nor expected to show up there, so they did a little video of them basically standing around in a parking spot of the parkinglot marketing their product for a few hours. They even got a contract from a large auto manufacturer to print a billboard on a wall, might be Toyota or Honda or something like that. Feel free to expose such disingenuous among the world of creativity, it's only going to help educate and help to prevent victims of fraud, make em streetwise with shared vulcan knowledge, like this very caring peaceful nonviolent atheist just did.

@@p_serdiuk Assuming starting speed is 0 (it isn't, but close enough), average speed is (600+0)/2, is 300mm/s. So, 300*0.028 = 6.9mm
@@projecthivemind3239 That's not how it works. You have to integrate to get x=a×t²/2 (after solving v=a×t to find where it reaches cruise and stops accelerating). I'm getting 8.232 mm.
@@daliasprints9798 Indeed and then you have jerk or PA settings influencing what happens when you reach the end of a straight movement. Bottom-line is that the lack of details on how exactly their motion system tries to achieve what they claim and how they counter the issues that fast motion brings (PA, input shaping, lighter print-head, super cooling power, more heat transfer in the nozzle, ...) makes it likely that whatever they deliver will be nowhere close to the wonders a Voron or Bambulab deliver. Also on multi-color: the cutter of the Bambulab is there for a reason - reduce the risk of clogging due to heat-creep. Retracting fully might slightly lower the amount of purging, but at the cost of way higher risk of clogging.
21m/s would be faster then a tesla i guess
And here's another thought, if it can almost instantly get about the print-space wouldn't it become a safety issue selling it without a cover? Fast enough to mangle a hand or something. Wouldn't want that near small kids for sure. And yes, I thought this was a bit fishy too.
I signed up for the combo, I got already 6 other 3d printers so it will for sure be interresting to see how the 7 colour printing works for this printer compared to my Bambu Labs X1C, the Snapmaker J1 and sooooon the Prusa XL with 5 tool heads...
Do you're who's backing this.
With how much this is on facebook ads, they have 100% spend more on marketing than product development. They went to CES, but are using kickstarter? Yeah no. 100% a scam. They may have a prototype, but there is 0 chance they have a functioning product.
It's a copy of the positron. When you point that out they deny it and claim they invented everything from scratch as their own original ideas. Naomi Wu already recently had interaction with these folks, she said to stay away.
The Positron isn't the first inverted FDM printer , but saying that they invented everything from scratch is bs
Again with the crazy claims of 10-12x faster. A box stock Prusa MK3S+ with default settings adjusted to the speed boat settings does it in just over an hour. 20 minutes isn't 10x faster than an hour. Also of note, that machine was shaking quite a bit during that print. They also use low quality footage and never show a close up, but it's pretty obvious that print is ROUGH. The most worrying thing is that the printer is obviously still in development as the 20 minute benchy video has a MASSIVE extruder assembly compared to all the other videos, and that's going to eat up a lot of Z travel. Prove me wrong, but I'm not giving them money for a product that is still in active development.
Seems extremely sketchy.
Thanks for pointing out to people the possible flaws.
I really don't know what people would back this?
Why would people who know about 3d printers not see the dodginess of this ie we've all seen photogrammetry fail whenever it's used. So why would this not? Upside-down printing, it just seems any benefits are far outweighed by prints falling off.
Why would beginners buy a printer on Kickstarter when they're are hundreds of printers already out there working fine?
At £500 I cant see why people are backing it like lemmings.
There does seem to be this video of a reviewer with one on youtube watch?v=lLPJvChIwpU
Well there's at least one out in the wild.
@@3dpprofessor People did comment his video was a bit biased and wondered why he had been sent out over other proper 3D printer UA-camrs. His channel does say he's in Shengen China.
Backed obsidian lost £400 got nothing, no way I am backing anything on Kickstarter
And you say worse case scenario is that the printer may be delivered, I would disagree, worse case scenario is that you get nothing.
ChatGPT 3D printer scam?
I paid to support SprayPrinter, but as they dragged time on, they said they wont ship the devices because they said they wanted to make a more accurate version of a software interface, even though they already had one that was shown to work reasonably good enough. Their 2nd last video was them showing one of the development team being shoved into a drum and sealed in there like a hostage, all hollywood production-like.
Their last one was of them standing around in another parkinglot scene with some walking coke spoon of a telsa investor who they claim convinced them to not release the product until they got more organized, and after that, no more uploads from them ever again.
Really pissed off alot of crowdfunders..and the devices were said to have been already made and able to ship to their prepaying customers.
I followed up over a year or so after to find out whats going on, because I saw one of their new version2 multicolor SprayPrinters actually owned and being used by an artist in the same country overseas that SprayPrinter is from. I said to the artist on his youtube page a compliment of his nice wall mural that he created with it, and he replied back saying thanx.
Following up invovled the owner flat out lying about who his name was, as he chose to use a fake name that I noticed was being used in another one of his uploaded content examples as he was participating in some text based forum type website while i researched the tracks that sprayprinter CEO left like easy to find crumbs on a path in the woods for detection, inadvertently.
He replied back to me with that fake name saying about feeling bad about it, which only pissed me off further due to the obvious boldfaced lying manipulative tactic, but I have yet to produce a documentary or encourage others to expose their flaky scam.
The really did seem legit at first, but they pissed away all the crowdfunded money on a whirlwind vacation in the sun, while taking the time to make an appearance at a big 3d printing event, yet they were not invited nor expected to show up there, so they did a little video of them basically standing around in a parking spot of the parkinglot marketing their product for a few hours.
They even got a contract from a large auto manufacturer to print a billboard on a wall, might be Toyota or Honda or something like that.
Feel free to expose such disingenuous among the world of creativity, it's only going to help educate and help to prevent victims of fraud, make em streetwise with shared vulcan knowledge, like this very caring peaceful nonviolent atheist just did.
Movie magic!
i saw it advertised on instagram so yeah its a scam
one word..."fictionalized"
Truth based fiction.
Dude do you not know how to read? The machine holds 2 rolls and the tower holds 5, 5 + 2 = 7.
