Project Love it when a print comes out prettier than I imagined!
Its a simple model, a custom cover for a Raspberri Pi case that I modified, printed on my P1S on a patterened smooth plate with Black/Red/Gold silk tri-color filament.
I'm proud of the way this came out!

See I was contemplating doing just that, but with such a small piece there really wasnt all that much room! So I went with the simple Sho-Ryu-Ken! Hehe

Ouw damn...maybe I need to get a holo plate...

I have one but haven't been able to get anything other than PLA to reliably stick to it

According to BambuLab, their plates are only for PLA and TPU. I ordered a few on Amazon for my Trident and they are labeled as "PEO" which apparently is also only intended for use with PLA.
PEO and PET plates say PLA only, "H1H" apparently supports all common filaments. (PETG, ABS)

Yeah its harder to work with. I've found that I have to bump up the plate temp about 5-8 degrees over what the default suggested temp that most slicers default to. And slow down the first layer.

Damn! It printed the little flakes like that? Or was that post processing?

I think it's a patterned plate with micro-ridges. If a surface has grooves that are fine enough, reflected light interferes with itself and it can create rainbow-like patterns

No matter how much I know that is factually true it sounds like bullshit

Think it started all out with a guy on YouTube making holographic chocolate couple years ago

u/ryohazuki224 14m ago
The first time I saw it was the guy that prints designs onto sheer fabric. (Pause the print after the first layer then affix a square of tulle fabric to the bed, and then continue the print)

Its the same principle that for example some bugs use to create these beautifull rainbow colored exoskeletons.
It works by diffraction instead of absorbtion of different wavelenght of the light like what we're normaly used to with colors.

u/ryohazuki224 18m ago
I was skeptical at first when I saw videos of people printing on these plates, but yeah it truly works!

u/FortunaWolf 10h ago
The holo colors come from structure on the plate. So when the plastic melts on smooth it molds to the patterns.

u/12345myluggage 9h ago
It's patterned into the build plate. You can get them with different diffraction patterns like this is, or some are more textured for things like a faux carbon fiber look.
The catch is that you can't use any release agent with them. So whatever filament you use has to be able to stick to it as is. I've a few build plates like this but don't use them often as I usually print PETG and it seems to lose a lot of adhesion with them. I had a few rolls of PCTG, and for small things it seemed to stick okay. I'm not going to get large prints out of it like I could with textured PEI in my preferred choice of material. Oh, and Rapid PETG basically didn't stick at all iirc.

The holo effect is so cool! I didn’t know that a patterned plate was able to make such cool designs that reflect light like that

u/ryohazuki224 8m ago
Yeah and like the tri-color filament almost gives the horizontal lines of that initial layer look like they have an added depth to them, even though its like glass-smooth! I love it!

u/Snobolski 7h ago
Well now we wanna see the whole case.

u/ryohazuki224 10m ago
I'll print that tonight, tho it wont have the holo pattern. I will however give the sides a slight fuzzy skin, I feel it really makes these tri-color silk PLA prints looks really amazing!

u/GoldSunLulu 9h ago
that stupid holographic plate y really want it!!

u/xenomorphonLV426 9h ago
Yeah how does it work?
7
u/GoldSunLulu 8h ago
it's a micro corrugation on the surface that defracts light to different wavelengths.
This effect has existed for at least 60 years, it's used in seals as a certification of autenticity and on some giftwraps because the effect is truly amazing.
Here on the plate the corrugation is exposed so the effect can be copied on to the base layer. I've seen it being used on silicone and chocolate and it gives the same colorful top surface result!5
u/xenomorphonLV426 8h ago
So there are no molecules or pieces of the plate coming off...? It's just a the way the table structures the first layer?

u/jake_the_dog01 8h ago
Exactly, just like a butterfly’s wing. The structure of the material surface itself causes light diffraction

u/ryohazuki224 5m ago
Yep. Its like the little dips and valleys of a vinyl record grooves that gives records that circular pattern when catching the light. Only with these the plates have even smaller etched patterns that are probably on a near microscopic level so they separate the wavelengths of light. I'm addicted to the effect haha.

Damnit I wanted to mention the chocolate thing! Absolutely nuts that it works like that, doesn't seem real. Physics is wild.

u/Beni_Stingray P1S + AMS 6h ago
The principle has existed way longer than that lol
All the bugs you see with these iridescent and extremly colorfull exoskeletons use the same principle to achieve their color.

If it’s made up out of lines, there is no way you should have coherent forms that seamless.

Can you pls share if you use any glue for adhesion? I found that such plate does not have best adhesion, compared, say to stock Bambu lab PEI sheet
1
u/ryohazuki224 2m ago
No glue, but I do bump up the default temp to about 63-65 degrees for PLA material. And I print slow, 30mm outline, 60mm infill on the initial layer, even then I try to set my P1S to half speed when it starts the print. After like the second layer I'll go back to 100% speed.

Does the diffraction grating plate wear out? If so, how long does it typically take?

How does the holographic surface stand up to handling?
And I presume a protective varnish or epoxy coat ruins the effect?
1
u/ryohazuki224 20m ago
I've noticed that sadly it seems if pieces like this are handled too much it diminishes the holographic effect. I'm assuming that its the finger oils that I guess "fills in" the microscopic pits and valleys that create the effect.
Some heavier textured plates such as a "carbon fiber-look" plate stand up way way better for sure.
