I work in a masterbatch laboratory and can confirm, pigments can make a colour behave very differently. Usually it's way less pronounced in a finished product, with dispersion values ranging usually between 1 and 4%, but as seen in the video - it still makes a difference. A thing I noticed for example, which wasn't mentioned here but I can tell from experience, is that silvery/glitter colorants make the extruded material way more prone to absorb moisture, it's worth keeping that in mind

This works for other products as well. My wife and I have a commercial embroidery business and one of the first things we learned was that black embroidery thread and white embroidery thread are more prone to breaking than other colors. Black thread is usually another color that didn't come out well, so it was bleached and redyed black. This is also true of white thread. It was usually another color then bleached heavily to make it white. The bleaching and redying process weakens the thread.

@SianaGearz Жыл бұрын

Good to know. Yeah i'm sure some black plastics from less trustworthy manufacturers have black be all-regrind with extra masterbatch; which is a problem for ABS in particular since it degrades heavily in the process, but would be noticeable for other polymers as well. I think some other colours can be full of regrind too occasionally, grey for example.

@longnamedude3947 Жыл бұрын

That makes a lot of sense, so dark colours are dyed black because cost wise it is easier and more cost effective to dye it black than it is to try (and fail) to bleach out all of the existing colour.

Didn't even notice that at first, maybe the weaker prints had slightly more pigment than the stronger ones? Many of these pigments are so concentrated that even a large difference in concentration wouldn't be very noticeable.

@infernaldaedra Жыл бұрын

That's the problem is that each brand has different mixes for different pigments and when we are testing all similar materials with simple tests we are going to start seeing the variation in the results itself where each individual tested filament roll might behave differently, what if the weight is different from pigment as well as moisture. So in turn we eventually do need to start testing further into the results to get a definitive conclusion

Used to work for LEGO back in the day, supervising various design teams. With LEGO, it's mostly about "clutch power" (strength required to pull two elements apart). Around 2005, we ran into a lot of trouble with our new light blue: apparently the pigment had an impact on shrinking during the cooling phase, leading to our models literally falling apart as all elements made in that color were oversized by a few 1/1000 of a millimeter...

They must be adding other additives specifically to compensate for the property changes brought on by the pigments, so they have to tune each color to be roughly the same "strength," hence the relatively small spread on the hook test, which is the most practical. So then maybe a material tuned specifically to be strong might see less of a spread between different colors, since the manufacturing goals are different. Would be interesting to see some tests on PLA+.

This is literally why I create a profile for different colors of filament using a temperature tower and extrusion calibration cube. Once they add a different color component to the plastic, every color takes on their own unique properties. I have found that by starting with the existing profile for the manufacturer and material, when one exists, and generic profile when one doesn't, that different colors from the same manufacturer typically require slightly different extrusion multipliers and temperature to achieve best results. Of course I'm only going for appearance and extrusion accuracy, not strength testing.

Thanks, Stefan, for another good video. I no longer use PLA because of its distortion over time when under load, such as shelf brackets, and always found white to be a poor performer with its layer adhesion. In those days, printer issues were more common, and filament dimensions, nozzle temperature control, and cooling were major issues. Today, I use PETG and Amphora based carbon fibre filaments. I find that black PETG is more brittle and that transparent is more ductile, while layer adhesion is similar and much better than PLA. I do print at a fairly high temperature, usually 240°C with a 0.4mm hardened nozzle on a Mk3S for all filaments. Sunlu PETG is the brand I use at the moment. I am now trying the Revo nozzle, so there are no substantative answers yet on that one, but the first models appear fine. I'm still waiting for the Obxidian nozzles for the CF filaments that you might consider investigating some time.

In my experiences, silk and matte finish pla has always given me problems, mostly with layer adhesion and bed adhesion. For colors, I’ve found to like grey and black, I feel they warp less and offered measurable difference in just about all parameters. Blue has always seemed to be very easy to print and offered very smooth, clean prints. And red the worst, I feel like it absorbs moisture much more then others, anytime I need to print in red I dry it for a minimum of a day and I store it in desiccants too, I also feel red, in my experiences, are the most fragile, but I feel that’s because the extra moisture absorption I’ve experienced. I do a lot of prints for orders, like custom Starratt tool boxes for clients, friends and family, so I do have a ton of experience in red pla and pla + printing. And I feel the differences between colors in pla+ are less then plain pla. But these are my simple experiences and thanks for the video, glad to see some I’m not just going crazy with noticing differences between colors of the same brand and type filament.

Printed one in Eyrone Blue and its sturdy AF printed another one with the red one for a budy to pain and again snapped off at the seams. So i do think Red is a poopy PLA to print if you need something sturdy and infact the blue stuff i print rarely breaks even when dropped wherass my Silk and Red just are so brittle as well as my OD green matt filament which breaks easily at the seams. Printing at different temperatures doesnt help at all when testing. Oh yeah PLA+ Deffinatly worth it if you need stronger material without switching to a different plastic type.

Then I printed some final parts with black PETG by M4P. The behaved really well. Last I tried a military green PETG, and it failed where the others already had more mileage that this. The green one broke not along the layer lines, but in a diagonal direction. I improved the part at that spot, now it holds, but I was really confused at first.

As a disc golfer this explains why we end up with different properties based on color. There are often discs that were made from the same run, just different colors that fly noticeably diffently.

I've noticed differences in colours of the same materials before. Most recently, when printing a lot of Overture pla for accent colours, it's been very noticeable how much more difficult to remove the supports are of orange, whereas white almost falls off on its own. So very interesting to see the results in the video.

Glitter filaments are usually significantly more hygroscopic, which makes sense, since many contain mica. I have to regularly dry my galaxy-black Prusament ASA, but never have to dry non-glittery colors. The same seems to hold true for PLA, and glitter PLA also becomes more brittle as it sits on the shelf vs. non-glitter. For PETG I find that the more heavily pigmented, opaque colors have better print quality with less stringing and blobbing. The biggest problem with PETG is that it's very sticky and goopy, and pigments seem to reduce this property. But it probably lowers strength.

I have natural PETG here behaving like a dream, and sunlu opaque blue and it's giving me trouble, like i sure can get decent looking prints out of it, but i do not get any sort of semi decent layer adhesion! Infuriating. I have to drive the temperature way up to get it to stick to itself, and then it blobs and strings more than the natural.

As usual, great video Stefan! I think a good baseline would be to do a tensile strength on the filament itself right off the roll. Measuring the diameter with a micrometer would give you great precision since a small variant on 1.75mm makes a big difference.

Yes, I have considered that (10 years ago) and that's why I've been printing structural parts preferably from natural white ABS.

Please create a series of videos comparing the properties of filaments types across manufacturers. - The manufacturers probably won’t release their raw materials manufacture and mix recipes. As well as added modifiers. I would really like to know which manufacturers ASA, ABS, PC, and nylons have the properties I’d expect when choosing a material. I’d like to know if a manufacturer adds modifiers that improve general user performance but negatively affect properties.

For your extension metering, I know there is software that can use video footage to calculate the displacement field in a specific sample, also resulting in a strain field. The software I know of is called DICengine. I haven't used it before, but seeing as you already film your tests this might be an easy addition.

Interesting ! My intuition has always been white is the best overall, seem to be held out by these results. Black I have always had issues with. Silver is an eye opener though - always assumed it would be super weak, and have not used it, tended to print white and then spray paint, but looks like if I want to make a mount that I need to anneal in particular its worth a try - cool to know ! Contains real metal particles I guess ?

I am basically only using DasFilament filament in matte black and white. From time to time I have issues with bed adhesion, but that's more on my leveling and my extruder. I really like their filament

@YensR Жыл бұрын

Very interesting, I've wondered about bed adhesion as a function of colour, seems it also affects other properties. As a point for potential improvement of such tests, there are some missing graph numbers (ductility) and some graphs with supressed zeros which make small differences appear larger than they are.

Second the point about misleading graphs. Quite annoying having to pause and try to figure out what the actual difference is

Great video and very interesting! In a similar way, I have recently wondered if print speed affects strength. With the wider availability of super fast machines like the Voron, RatRig, and Bambu; I'd be curious if the strength is affected. I imagine it would come down to material, cooling, and a number of tuning choices, but if those could be kept constant it might make for a good video.

@TheFabo1981 Жыл бұрын

Very interesting test! Thank you for the great videos and the invested time. I have also observed that filaments behave differently across different colors. Basically, each color variant requires its own calibration. This means that the extruder steps, flow, and PA/LA must be adjusted and determined for each color variant, taking into account the different shrinkage of the materials and compensating for it. Have the appropriate calibrations been performed for each color variant in the test trials? I'm looking forward to many more videos.

I have generally found white fillaments of any type print differently than other colors. Especially the case with ABS. I didn't expect it to do as well as it did in these tests.

The testing and results you show are amazing. Thank you. In the future, can all graphs start at 0? Some of the results for strength and such were trunkated and make the difference seem more significant than they are.

Have had same-filament-color-to-color differences several times, but never had enough batches or precise knowledge of filament condition to distinguish between color-to-color or spool-to-spool dependency. Though always thinking about it because you know - additives.

Have you tried any layer adhesion tests with/ without an enclosure? Seems like it would also create less stresses in the part aswell.

I use Zyltech PLA a lot for prototyping and making brackets and enclosures for my various vehicle projects because it's really cheap but still reasonably good quality. I have found that silver, clear, and clear blue are the most durable and are the least likely to have threaded inserts spin or get torn out. But if I want something to be super precise; I use milky white as it seems to be the most consistent with almost zero blobbing or stringing.

I work with industrial plastic extrusion machines used to put plastic/PVC/silicone insulation on wires. We used all sorts of colors, even custom ones. From day one during training we drill in the fact that color pigments are actually a contaminate for the plastic, reducing their effectiveness, thus the percentages we use are important and not to be deviated from since it will change the characteristics of the insulator. While we generally don't care about the mechanical strength of the insulation, we are aware that the natural/clear version is generally stronger than the colored added version. It is especially noticable with purple. For whatever reason, all the purple pigments we have do not show as well as the others and we end up using a much higher percentage than other colors. It creates a minor but noticeable difference in the quality of the finished plastic.

I haven't done actual measurements, but my prints with "natural" (pale translucent white) have seemed strongest and have had a little more flexibility, making the "minies" for TTRPG break less often if dropped.

@infernaldaedra Жыл бұрын

What polymer blend? Or filament type? Pale translucent white doesn't sound the same as natural but neither is regulated or standardized but usually natural means free from additives. Translucent white might mean they actually tried to brighten up and clear the filament

@H0mework Жыл бұрын

That actually sounds like it's the weakest of the materials with low rigidity and higher flex and ductility, which is a good thing for when you accidentally drop them.
