Product request: High speed PLA filament

High speed PLA filaments will be a good addition to BL’s PLA line. If no one else, model designers will welcome them. Can start with black, gray and white to test demand. For prototying or at least in the early stage of it, these 3 colors are good enough.

You knew this would happen, blame yourself.

Warned you

None of those are colours.

  • Black is the absence of colour
  • White is the combination of all colours, nit a colour of it’s own
  • Grey is a weird pretender sitting between nothing and all.

I disagree. They might not be monochromatic colours, but most natural existing colours are composed of light with several or even many wavelengths.
Black / white / grey are colours with zero saturation. And even that is relative to a reference light colour. So they are definitely colours, even if not very colourful :crazy_face:

Coming back to the topic :stuck_out_tongue_closed_eyes::

Actually, I think there is no clear definition of what constitutes a high speed PLA. In my experience, they behave very well at the highest speeds, so I would say, they deserve the title highspeed PLA even if it does not say so in the title. What is current PLA basic missing for you?

A high speed PLA is specially formulated to have a significantly higher melt flow index (MFI) than regular PLA. It allows for faster extrusion and quicker cooling.

Even if all the printing speed setting are the same, high speed PLA will have higher max volumetric speed (MVS) which reduces printing time. I have tried editing the MVS of another brand and it worked. But still I don’t want to keep doing that because:

  1. I don’t want to run into problems down the road
  2. When publishing a print profile, I don’t want to have to tell users that in order to achieve the printing time as shown, they should go editing the MVS of their filament, which not only defeats the purpose of the one-step printing, a benefit of having print profile, but also the possibility of users’ filament cannot be printed at the MVS.

If BL PLA Basic filaments have been formulated to have the property of high speed PLA, then I haven’t been made aware of. In that case, it could be a simple rename of the brand.

I thought that’s white, because in color theory, white is the absence of color. For example, Mont Blanc was so named because of that.

Another example is that African Americans are called black, or people of color, not people of no color.

In my view, black, white, and different shades of gray, are all colors, even though they are not the primary ones. But we can differ, as long as we know what color, or not color, one refers to.

White is the combination of all visible wavelengths.

Imagine space, remove the stars (like our sun), there are now no light sources.

Now everything is black, the absence of colour.

You may be thinking of subtractive colours vs additive colours.

If you start with black, you add the colours you wish to see, by adding lightwaves for red and green you get yellow. *

If you start with white (like paper, the most common way as kids we experience colour) You add paint with the colours red and blue and get purple. *

  • Additive colours: Red, Green & Blue.
  • Subtractive colours: Red, yellow, Blue.

* (edited the above as I rushed and inadvertently swapped them from the correct way noted above.)

A suitable short-form article if you are interested.

You switched at the end.

Subtractive Colours: Red, Green & Blue.
Additive Colours: Red, yellow, Blue.

It’s the opposite. Additive color primaries are red, green blue (RGB).
Subtractive are red, yellow and blue.

Subtractive is when a material manipulates the light hitting it, by absorbing certain wavelengths and reflecting the remainder. Thus the term “subtractive”.

Additive is when we simply stack wavelengths to achieve the combination.

Regarding the whole debate of the term “colors” (or colours for those of you who prefer British), saying that black and white are not colors is only for the theoretical representation.

When we create what we call “black” and “white”, in filaments or otherwise, we can never hit true black or true white. And since that’s the case, we can say “black filament color” without it being wrong. We could refer all filament colors to the RAL or PANTONE lookup tables, and see that there is no way we can ensure perfect neutrality in physical form. As data, sure we can say that #000000 is the hex for pure black. But that’s additive colors - not subtractive. And for subtractive, we can never create anything that’s perfectly neutral.

I bet that PLA-HF will come when Bambu Lab creates a printer that hits north of 700 mm/s print speeds with 30,000 mm/s2 accelerations - because then it’ll be a necessity. As it is now, with the current crop of printers offered, we don’t really need a high flow PLA, since Bambu Lab filaments clocks in at around 35-40 mm3/s, and that’s only a limiting factor for rare situations - such as using a 0.8mm nozzle at high speeds when using 3rd part hotend/nozzle, such as the one from E3D. With the stock hotend and nozzle, we’re closer to 18 mm3/s although Bambu Lab’s own PLA profiles states 21 mm3/s (I have made custom presets that dial them down to 18 mm3/s because our printers simply can’t maintain the correct wall thickness if run at 21 mm3/s).

It is what happens when you try to reply to all the forum messages while uploading a new model with seven profiles and several ratings.

I rushed the last part, I will edit it to fix it.

But, we can’t say black is a colour because it isn’t. I was talking about colour theory, which all started as a joke from above.

It is weird how many people do not think colour theory can be fun. I bet if I were doing stand-up, my absence of colour line would bring the house down.

It is more that we speak it, being British and all.

As I have said to other people, Webster removed all the cool spellings because he thought Americans were too stupid to learn to read and write it if there were basic rules attached; his words, not mine.

I noticed that, too. Artificially increasing MVS won’t help if the filament doesn’t have a higher MFI.

There no need to wait for higher printing speed before making a high speed filament. Even with the current speeds, having a much higher MFI will cut down a chunk of the print time. For those of us who go through multiple iterations during prototyping, it could mean hours saved each day.

This depends on if you are talking Light color or pigment color. They are different and they react differently.

No, not at all. Yellow and blue to get green. :wink:

I use the Munsell color system for pigments. Linky

As I said earlier…

Clearly the image I provided showed what I meant to say.

I am fixing it now.

At least I know you all read what I write!

I could not help myself when I saw that, and yes, I do read what you write.

PLA-HF might be hard to create, like TPU hard, if they want it to have similar qualities to PETG-HF. PLA normally doesn’t have a high melting temp nor good UV resistance, but if they’re just going for speed I say it might take 2 months (it wouldn’t be high priority), considering that they haven’t started.

Don’t rely on what I say though.

If this gets released, I don’t want to see a thousand “High-speed Benchies”.
