Underextrusion is common due to the drive gears compressing the TPU - I used to run as high as 130% flow rates on older printers even for 95A with big 1mm nozzles for low backpressure.

I had to design my own extrusion idler assembly to combat this on my printer. It grips the filament only tight enough for the drive gear to engage and no tighter. That was the only way for me to solve the extrusion consistency problem on my printer.

I love these filament deep dives! It would be cool to see some metal-infused filament

the "reflect internally" from wikipedia is total internal reflection. when light hits a medium that has a higher refractive index than the medium on the other side at a larger angle than the critical angle, the light will be reflected instead of refracted

Retro reflective glass beads were used in certain projector screens in the days of cine film projection before we had LED video projectors. I would say the phrase 'silver screen' but that is slightly different, with a wider viewing angle where as glass bead was brighter on axis but less bright for people off axis seated to the side of the cinema.

I love the macro shots! I remember when Kai Parthy started pumping out weird filaments, sadly it seems like they’ve disappeared from the 3D printing space.

Can you polish the surface? (Maybe after freezing?) And while I'm conjuring up side projects: Does it gain strength through annealing?

Dig the black and white noir intro. Sweet

I love these explorations. You should see if Zack at VoidStar still has some of that cursed beef jerky filament. I bet that's gnarly under the macro lens.

I'm glad people are appreciating the weirdness of the colour grading in the vid, I was hoping for that 😁

Before watching the video: glass sounds like a nice way to ruin your nozzle.

Literally thinking a real world use case for this could be to print on fabric for custom reflective designs.

I never thought I'd watch a video that clearly shows that the balls are smaller than the nozzle orifice. Gotta feel for anyone addicted with that condition.

i literally had this idea once, and was hoping it would be a thing. Im sad that its, not really for sale, when it is its price is high, and that it dosnt seam to print well, or last. they should reduce the amount of retroreflective balls, so it is able to have some strength.

So an interesting extra modifier would be to add some fumed silica to improve flowability of the mixture

@SianaGearz

2 ай бұрын

Improve flowability? I think this will just thicken it up and make it REALLY difficult to push through the nozzle! Plus it may mute the glass bead reflection.

@zapl80

2 ай бұрын

Fumed silica probably just acts as a thickener in that case. It helps flow in powders. And due to it's porous structure it might make prints less shiny but could also make it more moisture absorbing. It's apparently used for powder based laser sintering as a de-clumping agent and in resin printing to thicken the resin but I doubt it would help in a material that is already a messy goo. Most additives in FDM printing decrease viscosity or melting point in some way. Would try with less or smaller particles to improve flow.

@SianaGearz

2 ай бұрын

@@zapl80 My familiarity is from epoxy work and it's used for thickening. It's why your typical 2k epoxy adhesive isn't as runny as oil. My second concern is that it'll cloud the carrier by presenting a structure of different refractive index to base polymer; in turn its refractive index may be so close to glass beads, that it'll touch and break their total internal reflection effect on incident light, allowing more light to escape into the resin and get diffused instead of being thrown right where it came from. I don't believe hygroscopic property is a concern, it's a feature in air but not when resin has been allowed to fully absorb into it and de-aerated. It can reduce hygroscopicity of polymer. I think also why you can't just have a retroreflective glass bead filament with a better behaved carrier polymer such as PETG or PS is because the refractive index of these is indistinguishable from glass, so it'll just look like normal PETG maybe just a little cloudier.

Does it become more elastic if you pre-heat the filament a bit? (so, not more stretchy, but more form retaining)

As a Dutch person I'm not entirely sure what exactly those letters stand for but the data I do have says not to heat it over 260 degrees however nothing about cyanide. Probably gonna look up more about the material from other suppliers before I'll use it again. So far I've had it running for hours and I'm still alive so so far so good but maybe I do need to finish my fume hood before I proceed using more of it. Bloody hard to get good prints instead of blocked print heads using below 85 hardness filaments though, even with my direct drive extruder.

Yeah a release agent would have been useful. I don't normally bother but this stuff is weak enough to break off.

Just some retroreflective filament, not all that useful in that color but would be good in red and orange.

.... Thats a lot of balls.... So.... Hmm...more balls than the locker room at LVAC 😂 Also the filament is...really pretty honestly. You could dual filament print with this and use it for text to be very bright and visible.

I might consider printing it if it didn't look like such a pain in the glass..

Hmmmm, this would be great for printing out your own glass files for model making, and if you nead a more coarse option just print with "fuzzy skin" option turned on. Just think of all the diferent custom shapes and forms you can print them in.

I fail to see an application for this filament that isn’t done better with some simple retro reflective paint. My first thought was ”cool, it’s flexible and wouldn’t flake off”, but considering how easy it was to break that doesn’t seem to be the case :(

Saw this on Zack Freedman, awsome to get a bigger dive

I should finish a retroreflective thing. Currently i am using a hat with LEDs and batteries and an IR modified PS3 Eye as my head tracker for simulation type games. Ideally i wouldn't need to wear a battery and wouldn't need a wire either. I know it's not much weight and it doesn't cause discomfort but the LED based build somehow lacks elegance to me. I have bought some retroreflective tape circles from a bicycle store, allegedly from 3M material, but they haven't actually worked that great. Maybe my LED placement wasn't great, even with light quite close to the lens. I think next step is to deshroud the camera lens or build a really tight LED array and ALSO to give the retroreflective targets a bit of a curve, make them at least cylinder shaped if not ball shaped. Yes the tape appears to be made with glass micro spheres. It seemed to work very well straight on but i didn't get enough of a working angle out of it - considering i can't get a ton of distance between my targets and the camera/light. But i have never considered printing an inside corner and applying some chrome paint to it... perhaps i should... I have some Chinese chrome marker pen which is sort of a clone of unobtanium Molotow pen and which turned out surprisingly decent and really really nicely put together, it's actually much better sealed and much smoother action than paint marker pens that you get as store brand around these places... not to speak of the unique paint. And the price was ridiculously low as well. But i still think tape is going to work better. How to determine how much of this filament is balls? Well you could sacrifice some of the filament to a suitable solvent and then wash out the balls... somehow. To then weigh the balls vs. source sample. Modulor will sell you methylene chloride after you give them a signed note that you're going to use it as a plastic welding agent and not say as a paint stripper. Not that i think it's worth it and i'd bet on this failing in a myriad of ways at the filtering stage, but you asked so i had to think about it. I can't see myself printing retroreflective filament. I'd much rather apply a surface treatment like sticky tape, fabric or paint or something of a kind on top of a normal 3D print. But also it's good to know that it exists and is sort of terrible.

Interesting stuff. Great video!

I tend to print at 30mm with a 110 flow rate for better results
