    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
      @SianaGearz Pƙed rokem +3

      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
      @longnamedude3947 Pƙed rokem +1

      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
      @infernaldaedra Pƙed rokem +7

      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.

However after a few days the filament was breaking in places and when I picked it up, it was like I left a cheap toy in the sun for a year because of the way it broke apart like an autumn leaf.

    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.

    With some of the graphs the standard deviation (thanks for putting those in!) makes it a bit tricky to see if it's very significant (looking at the layer adhesion test). Super interesting though and quality content as usual!

    I went through three different manufacturers of silk PLA and two of them had major problems with delamination no matter what temperature I printed at, I have sacked silk PLA now but I am using a lot of matte PLA and carbon fibre strand PLA and PETG-CF and PA-CF Nylon, the first matte PLA I used was problematic to start with but I persevered with it and now can print perfect parts with all these new filaments.

    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.

      no no i think you are on to something here. i use Eyrone filament mainly. Black seems almost seamless and perfect. Blue seems sturdy as heck, The red one i used for a MK50 infinite articulating pistol imediatly snapped of after pulling the slider a few times. 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. Ofcourse not a huge difference compared to normal but a bit more sturdy is often enough for Airsoft purposes

    I noticed this in CNC machining too with different colors for the same plastic (Propylux) Some were harder to cut and had worse surface finish

    • @chipwallaceart
      @chipwallaceart Pƙed rokem +2

      Yep, I've worked with thermoplastics for decades, and colors always make a difference. Black PVC takes a hit on strength and dimensional stability because it's packed so dense with colorants.
      Machining colored cast acrylic, yellow cuts smooth, beautiful shavings of plastic come off the part. With red, small chips and a rougher finish, so I had to compensate for it.

    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.

  • @toma.cnc1
    @toma.cnc1 Pƙed rokem +1

    Yes, noticed a lot of difference in layer adhesion and strength while using Gembird filaments, over 70 KG of it. Lately switched to Plasty Mladec and C-Tech, first is very very good, second also good and i found out they have Orange HIPS boxes with Orange PETG inside, so i keep buying it as it is cheaper here! Also got some other HIPS colors from C-Tech that i will have to test. Gembird Red and White HIPS is very good, much easier to print than ABS or ASA by a long stretch.

    Out of the PLA varieties I use, Clear PLA feels like it has the best resistance to flexing to me. It also seems less vulnerable to becoming brittle due to moisture, which is invaluable, as I'm based out of Japan where summer gets unpleasantly hot and humid.

  • @WouterNederstigt
    @WouterNederstigt Pƙed rokem

    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.

    When i print parts that i have to paint afterwards i always print with uncolored material aka natural. Parts come out stronger, have less stringing, curling, warping... your get the point.
    White filament gives me the most trouble, while "galaxy" colors even clogged the nozzle a few times when changing to other filaments after printing.

    My company works with PLA+. If a client needs a strong piece (within the possibilities of what PLA can achieve), white is everyone's colour of choice and there are no complains. Other than white, blue.
    Orange, grey, red and green were other colours I've worked with, but white is by far THE one requested.

  • @fhuber7507
    @fhuber7507 Pƙed rokem +6

    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
      @infernaldaedra Pƙed rokem

      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
      @H0mework Pƙed rokem

      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.

  • @rabenklang7

    Very interesting Test, loved it! It would be awsome if other CZcamsrs would do the same, to get evidence in repeatability with different products. Also your visualisation with all the graphs are top notch, a radar chart for each filament would show ther overall properties at one glance, bit it would be hard to compare all in one page.

  • @YensR
    @YensR Pƙed rokem +1

    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.

    • @mjb10

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

  • @BanjoJeff
    @BanjoJeff Pƙed rokem +1

    If you revisit this, you should control for batch variation within the same colour. This variation could be partly explained by each colour necessarily being from a different mix. Is the relationship consistent between different batches of the same colour?

  • @kaylor87

    I really like your comment about white amplifying any inconsistencies in your prints -- I've been trying to dial in my settings lately, and been getting really frustrated that I can't seem get a perfect result like I usually can. Now I'm starting to wonder if it's because of my white filament, just making issues more obvious than normal. I'm gunna swap colors tomorrow (:

    Indeed, I experienced a difference between different colors of PETG. I use PETG for parts which get hit by metal parts. My prototype was made with transparent green PETG, and had no problems. 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.

    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.

  • @ChristianBehnke
    @ChristianBehnke Pƙed rokem

    I've never had to use any of my prints for strength comparison purposes but I have found different colours from the same manufacturer will have different properties in the quality (eg. stringing), so I've been ordering different options as I continue to explore.

  • @TrippyRiddimKid
    @TrippyRiddimKid Pƙed rokem +2

    You should do a test on annealing/warping based on print speed. It would make sense that a model printed slower would have less internal stresses, so should warp less when annealing, in theory.

  • @fwiffo
    @fwiffo Pƙed rokem +3

    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.

    • @SianaGearz
      @SianaGearz Pƙed rokem

      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.

    Hey Stefan, are the print layer inconsistencies you show at 6:34 fixable on a Voron 2.4? I have a 2.4 that I have tuned a lot and my layers look similar to yours in this video. I had watched your video "(HOW) I fixed the ugly layers on my 3d printer" and the layers you showed post fix seemed absolutely perfect. So I'm wondering if these inconsistencies on the V2.4 could be related to the Clockwork extruder? I'm currently running CW2 in a Stealthburner. Thanks!
