Great idea of offering filament rolls without spools for those of us who have printed our own spools.

[@survival_man7746]

And to reuse our spools, I have like 20 empty spools i don't know why I would print any

[@AckzaTV]

Or anyone with a bambu printer who has at least one banbu filament spool. Also yes we can print out own and we should give them away I literally was forced to throw away like 10 plastic spools by my parents lol didn't want to but yeah I should be able to leave them at a local 3d printer parts depot like at my san diego downtown library where they apparently have a bunch of good big new 3d printers

[@AckzaTV]

He should offer a subscription plan and most bambu users have a few reusable rolls

[@merrillalbury8214]

@survival_man7746 the printed ones can be unscrewed to put the unspooled filament directly on them and then be screwed down to fit the width of the unspooled filament. Beats getting or making a spool winder to transfer the unspooled filament onto a spool.

About the warby Parker story, it’s all about your contract. Do you sell *finished goods* or *manufacturing services*? With finished goods you have a responsibility to meet a particular spec. With services you sell your time and materials. Maybe not every customer is going to find that arrangement satisfactory, but if things go wrong they’re still on the hook for time and materials, it’s your expertise that you’re bringing to the table, not some widget.

I want a utility company to just pipe in a filament reel (and liquid 3d printer resin) imagine the little pully system in a tube nd how fast the filament could be spooled through a tube, and the giant filament reel centers distributed around the city like the power grid etc .

[@syranth8912]

We've used the original Slant3D printable spool for re-spooling material since it came out. I have three sets of print in my personal office. You have our support for spoolless packages.

[@AckzaTV]

If he offered you a bulk subscription plan that locked you in, would you buy 10 kg spools once a month ? I wonder if he could even offer that

[@syranth8912]

@AckzaTV yes. We've put purchase plans together to save money to get 25k spools, then respool down to fit the stations. We buy mostly 3k spool sizes when possible for efficiency. That's part of why we use printable spools from the Slant3d pattern.

Imagine something like etsy/ebay built into the makerworld bambu handy app that let you cloud print to any 3d printer like with octoprint for android, so an app that does print farms and helps you select models you can legally print and sell or print and sell and give a city to the original model owner so you pay them later when you make a sale and don't even print untill you get a sale order...like an crowdsourced uber or airbnb for 3d printers that helps you sell with built in store in the slicer app lol

[@rbrianlindahl5499]

Still have a box of SlantSpools - most printed with the KVP plastic that originally led me to them. Would probably use spool-less from Tangled IF... something happened to fix the one problem I've had. Don't remember it happening on the old Ender 3 ... but the Bambu A1 mini with AMS lite... the spools fit on the AMS lite, but something about how it feeds is different. The filament coming off the spool has a strong tendency to get caught in between the spool and the remaining filament, to the point where the printer jams. It got so bad with one particular remaining spool that I despooled it onto a leftover spool from another source and used the filament that way. I do like the SlantSpool design... so much so that I reverse-engineered it and made a small version (< 1" hub, 3-4" outer diameter) to store the myriad of wire that I find myself storing as a maker who is doing a lot of electronics. :)

[@davidedwards9157]

For spool-less filament... Do you know if anyone has tried center-feeding the filament? I've seen it work for baling wire and twine, and while it certainly wouldn't be a universal solution, it seems like something that could work pretty well with non-brittle filament. For those of you who haven't seen something that uses it... The coil sits in a tray, the end of the coil in the middle gets fed through a hole in the middle of the tray, and then it just gets pulled from there. Why it's a win: The coil doesn't move. Doesn't need to, what's spooled is getting pulled to the center, and there's nothing in the center to stop it.The tray doesn't rotate. Doesn't matter how much the spool weighs, because that itty-bitty extruder motor doesn't need to turn the spool. Why it's not a win: The mechanism is putting significantly more torsional force on the filament as it unspools than it would on a conventional design (where it would only be a tensile force), so brittle filaments just aren't going to work here. Also why it's not a win: Changing out filaments is going to be tricky; as long as you're pulling one end to the center, it shouldn't tangle, but once you let go of that end.... But if you basically print from one coil of a filament that can handle a little twisting until the coil runs out, it seems like it might have a niche.

[@tomasparrado873]

Spool-less is my preferred way. I can't be the only one

[@Mildly_Amused]

I thought another youtuber already 3D printed their own filament last year? I didn't think it was new.

[@Lionnnn.n]

iirc CNC Kitchen did a proof of concept video

[@stevencullen6261]

Going spooless has its pros and cons if i were to weight the decision i would say the end grade is a wash handling as a reload could work but tangling could be a nightmare but can reduce packaging size not to mention the cost of the spool itself but if the cons can wrangled the cost of filament could (in theory) could drop by quite a bit

[@ChineseSweatShoppe]

A lot of places fail because of the exorbitant prices. My buddy needed a part printed, it was 599grams of pla and 2.5 days of printed. $12ish for filament and $2 for electricity. The overhead can’t be that much where that warrants $400 🤷‍♂️

[@RNMSC]

So following the channel, wondering when the new building grade filament is going to be available on Tangled....

[@davydatwood3158]

What I find interesting about the BMW story is that it implies BMW is starting to embrace the idea of "print the part where you need it instead of shipping it" aspect of 3d printing. obviously only in baby steps, but it's still a good sign. Also, you get a thumbs up for realising that "Jens" starts with a different sound than English calls for. :)

[@bernarrcoletta7419]

Any chance of a video on accounting for shrinkage in your prints for functional parts?

[@AckzaTV]

Can you make filament directly from crude oil? Could an oil company make filament? Is that what petg is and pla is from corn? If corn prices got cheap enough could petg get super cheap?

[@Slurgical_3D_Terrain_Channel]

I could see that to benefiting to my niche. I create 3D terrain for tabletop gaming. In the hobby we often run LED to light part of the terrain. If this could be integrated into the printing it would make it reachable and cheaper in production time if I were to create physical part of my terrain to sell.

[@Geoff_W]

Honestly going spool-less will make me buy more. Needing to re-spool off the cardboard spools is a huge pain point for me and it makes me want to pay more for the Bambu refills. Considering the number of people using the Bambu spools, it might make sense to just use one of the many printable spool centers that are used for re-spooling. There are plenty of them that are support free and completely ejectable. There are lots of good printable spools on that side of things too...

[@ThisisDD]

100%

[@Reewen]

isn't there a fix for the spool ams issue. I believe you can get an adapter on printables that essentially just ads an outline to cardboard spool so they don't get ripped to shreds

[@Geoff_W]

@@Reewen Sure is. Comes with all sorts of extra problems and caveats, might just casually break, have to be customized per-spool (re: inconsistent spools mentioned...grr 😡) and even after all of that still limit the flow rate of the machine because cardboard spools simply don't spin as cleanly as plastic ones do. Also cardboard holds MOISTURE, so it makes it harder to dry the filament....I could keep going but basically cardboard sucks. It was never a good solution for spools. Spool-less was always the best option.

Basically: "Here's the filament, get your own damn spools and figure it out!" Haha I love it Basically if the spooless "hub" is as big or bigger than most spools, anyone can print a few of their own reusable adapters if needed.

[@jimbrookhyser]

I want spoolless filament buying as an option.

[@MaebhsUrbanity]

On the largest print farm and being a uniquely diverse client, I think your point is fair within the west, but services like JLC3DP that do on-demand instant quoting with FDM and a similar PLA price to you. Though you still have a larger FDM scale I would think (and an API). There are other similar more domestically focused farms in china too I think. PCBway also operates a west facing FDM farm in china and maybe France too but I don't know much about it. I would be interested in your opinion on these as your competitors rather than talking about companies operating farms for their own products.

[@Jerrie-Lenore]

Differentiate your product! Sell 3.33Kg spools for makers. Sell a 3 pack of 3.33Kg spools as a 10Kgprint-farm pack. And fine, okay, make some spool-less 1kg for the masses.

It's annoying how much Bambu's AMS gets in the way of making cardboard spools. I really hope they are working on an improved AMS that is more compatible. Cardboard is much more recyclable than the plastics used in spools.

[@wolframherzog636]

The idea of the Bambu AMS to refill the plastik spools several hundert times, which is even more environmental friendly than cardboard spools which can be used only once.

[@DaveEtchells]

Easy solution: Paint the rims of your spools with clear nail polish. Very quick to do, no more residue on the AMS rollers :-)

[@logicalfundy]

@@wolframherzog636 you need really good buy-in from customers to make that happen. Polymaker tried, but shut down the program because nobody was buying the refills. I suspect Bambu's sales of refills is low.

So instead of just firing off 10,000 parts into the dark, if a client wants that many of something. Do prototyping with the client, make a single part and sent it to them, if it works and its what they want, fire away and make the batch. If its not, re work, fix and have them be able to see what they want and what problems might show in the original design.

[@RNMSC]

@@jtmoore42 There are a couple of solutions out there for that. Things like spindle inserts and spool edge adapters that cost simply the time it takes to download the model and print them, or at worst design up a model and print that. That said, no one wants to add work to their process of swapping out filament. For me that is a strong argument against spoolless filament, as nothing I've seen indicates that the time involved in getting a spoolless filament roll onto a 3d printer is going to be less effort than the adapters. I think it is a niche market in the long run.

[@NoMercyFtw]

Filament shouldn't come on spools if you want to spool you can 3D print a two-part one and the size one that you need or want

[@RNMSC]

I think that spooless filament users should be considering switching to bulk pellets that they can customize the color of what gets extruded, and never have to deal with filament at all. I don't see it being a major movement any time soon, though I've seen a few different videos over the years of people doing just that. I'm afraid that the same is true for filament. I'd realy rather that retailers like Amazon allowed you to specify whether you wanted spooless or not, but their search platform is more likely to start including bulk spools of sewing thread into their search results, than narrow down the results to what you're looking for.

[@NoMercyFtw]

@@RNMSC i cant wait til this happens

[@stefan-bayer]

@@RNMSC do you think pellets will become the alternative in the next 2 years? Up to now I am not aware of a company in the consumer segment that offers a printer in that field

[@RNMSC]

@@stefan-bayer I think the actual problem is that at this time there isn't a consumer avenue for buying the pellets. The ability to use pellets as a modification for off the shelf printers is generally available already. I don't see it as an option for the more recent high speed printers, but for pretty much everything from the reprap through most printers in the 200 mm/s print speeds, there are feeders that are effectively bolt on solutions that replace some or all of the filament path into the hot end. As to whether something like this will take off and become massively popular in the next couple of yers? No, I don't expect so. It could happen, and if there is one place where I would think it to be a likely update is in the commercial 3d printing space, A company like Slant3d that's already buying the pellet level stock, and is using that with pigments to generate filament that's then used in the print farms that they run, seems to me to be a company that may look at the filament making process and wonder if they can engineer a solution for printing from pellets that's highly reliable and can be replicated in volume. That solution may be using a fixed extruder hot end with the x-y and z axis all moving. That feels to me like a really bad option, but that fixed hot end is likely to be something that could be in a Z lift, with the bed being slung in x and y. I would presume that at that point we're not going to be using nema17 steppers, perhaps moving up to Nema 27 or larger, simply for rigidity to reduce the various movement artifacts. I don't expect that Slant3d themselves will do this, and I don't expect to see this on consumer end printers, where the price of the hardware involved is likely to be prohibitive, but I've been wrong a lot of times, and don't hold it against others who develop the things I'm wrong about.

[@viktorfoggo5692]

I'm sorry but your new master spool plan is an incredibly bad take. Most manufacturers work with their own spool designs due to sunken cost and greed. You however, are basically starting from scratch, so why not make your refills compatible with an already widely accepted master spool and help push the entire industry as a whole towards a real standard? I realize you think you can do it better, but so does everybody else: This is the death knell of standardization. One of the few potential good things to come out of Bambu Labs' "ecosystem" was an overnight widespread adoption of a good master spool system. Please don't let it go to waste (or be left behind) we desperately need standardization.

[@AckzaTV]

You deserve federal subsidies. Taking manufacturing from china back to USA is a very easy political issue that BOTH sodes get passionate and competitive about. JOE bidens administration seems like a perfect target for a 3d printer filament lobby, and theres plenty of 3d printer owners who would LOVE for federal funds to go to subsidize CORN OIL based pla? Seems like a dream for our government...use all that surplus corn and make something here in america thats relatively easy to manufacture so that americans can cheapky manufacture even more stuff at home in 3d printers. I want 5 even 1 dollar per kg filament delivered in bulk , so much that people are worried about where to store it :) so it will firce us all to buy more 3d printers just to process the fimament into toys and useful tools that never get thrown away and theres a lot of models that are insanely valuable and wont be thrown away
