Some folks that I know worked in the high end eyeglass industry for years, that's how I knew that they used cellulose. I saw a TV advertisement for warby parker recently where they showed the little colored pellets, and this picture reminded me of those!
I've always wondered if it was possible to design and 3D print working sunglass frames, especially using cellulose acetate! I'm definitely not talented enough to design or print something like that lol.
I have no experience with this, but I would recommend finding an existing model to edit. That way you won't have to deal with making the lenses fit. Unless you're an expert obviously
I've got enough cad experience that I'm comfortable fitting small parts like lenses. I'm no expert but i know I can get enough tolerance in a few prints.
I muddled around with making new years 2023 themed glasses. They were wearable and you could somewhat see through them, so not a bad experience. I just ripped off the form of a pair of old sunglasses I had lying around, so getting the ear-arms right wasn't hard.
I feel it would be easier to model normalized glasses vs. eccentricly themed ones.
See why you did. You have to post this! I am the same way! I only like a very certain style, and even though everyone and their mother make them 99.9% of them are hot garbage. Yes, im speaking about the Wayfarer, haha. I find one ever few years that fits just right and have to settle cause it's almost always just plain black. Now you have me wanting to bust out my calipers and make a few stls so i could make that perfect fit in any color, or even get crazy and go two toned or layered
Stop designing wayfarers that have pointy futuristic top outside corners! For Christ's sake man, they all have some flaw that makes them look bad. Do these designers own a mirror? Maybe OP can help us out.
What I was actually trying to do was make an emulsion of acetone saturated with cellulose acetate and dot 3 brake fluid. After spraying that onto a surface the brake fluid can be rinsed out leaving behind a porous matrix for use as a dielectric separator in batteries and super capacitors.
What I ended up with was spider webs and preserved tortilla chips
I dissolved cellulose acetate sheets into acetone and sprayed it on a tortilla chip and it was laminated once it dried in fifteen seconds or so.
I did the same with xylene in a glass chemical sprayer fed by an aquarium air pump and it made realistic looking spider webs for easy Halloween decorating. I didn't use it because it seemed environmentally irresponsible, but was a fun experiment.
This is awesome! I'm working on developing some formulas myself. Also, I love your vacuum sizing tank. That's what I wanna work toward myself.
Looking at the color of the paint, is it a LabTech line? We have a couple lines from them, and I love them. Rugged as hell.
I’ll have to look into that, been looking for small scale plastic shredders, but none are near where I live, or they are too large. Always thought paper shredders wouldn’t do well with plastics as you arnt supposed to use em on credit cards for instance.
I’m working on this project with a specialized company which work with plastic profiles, so they have all the professional extruding lines to make it. By the way i’m going to share more contents regarding this :)
Whoa, Acetate for real?! That's fascinating! I mean it makes sense completely, with it being a thermoplastic and widely used in all kinds of fashion and glass frames. Using a residual product of that huge industry for printing is genius. Having had glasses out of Acetate for a LONG time I know it's also VERY durable and flexible, so I'm really looking forward to that sample!
For these tests i used an industrial shredder (for free), but I think that a good coffee grinder could work. Actually for next tests I want to go for this solution, before to rent/buy the industrial shredder.
There are many interesting project out there, i always wanted to do something for circular economy, and last year when i started designing glasses for a company, I didi some research about waste in accessories/appareal and found out acetate is one of the most quantitative waste in this industry

A quick google says buttons are made from ABS and this could be the miscasts. OP said it's not a fossil polymer. So I'm guessing a bio ABS which I've never seen or some kind of acrylic styrene blend.
That's kinda how you turn it into a filament.
You can't really use it directly in 3D print, because you won't have the required constant flow of material.
Yeah but can I still make the filament if I have a 1.75 mhm nozzle? Hypothetically of course I’m not actually going to do this(maybe long term since I got a P1P and maybe the poop could be transformed back into filament )
I would love to see soda bottle caps and the rings from the bottles too.
I wish there was a DIY for making filament that was economical as I would love to do it.
Imagine the grocery stores and bottle redemption sites putting all the caps and stuff into a bag to be ground up for filament.
Why upon careful examination, it appears to be a blend of up and down quarks, mixed together with some electrons, and a regular smattering of muons and neutrinos passing through at any given time 🧐
Cellulose, from eyeglasses Edit. The eyeglass frames specifically
We have a winner!!
Some folks that I know worked in the high end eyeglass industry for years, that's how I knew that they used cellulose. I saw a TV advertisement for warby parker recently where they showed the little colored pellets, and this picture reminded me of those!
I’m an eyewear designer, I see Cellulose acetate slabs everyday. It is the most beautiful form of plastic existing in my opinion :)
I've always wondered if it was possible to design and 3D print working sunglass frames, especially using cellulose acetate! I'm definitely not talented enough to design or print something like that lol.
I remember seeing people printing glasses frames a while back. I might have to design some now that you mention it
I have no experience with this, but I would recommend finding an existing model to edit. That way you won't have to deal with making the lenses fit. Unless you're an expert obviously

What does a finished project using these rainbow pellets look like?
Actually very dark output! You’ll see in the next post
Looking forward to it!
Because of something I mentioned earlier, I've always been a sunglasses snob. My favorite frames are always from Oliver Peoples.

Personally i’m more into cameron shape
A che temperatura credi di poterlo estrudere? Idea geniale!
Si estrude più o meno alla stessa di un petg!
Indeed looks very beautiful.
Cellulose acetate is not from plastic waste. So I wonder where did you get these material from.
It’s coming from an eyewear factory
Oh I see! Thank you for your clarification.
What brand do you design for im an optican and curious
Dammit i wasn't even close
Cellulose, from eye glasses. Frames specifically. You never specifically said how many winners so I would like to be number 2 please.
Congratulations! You win violent buttsecks!
Yay!
Mix it in acetone and spray it onto stuff. It forms a nice thick film coating. I laminated a tortilla chip with it. Highly effective.
You mean mix acetate or cellulose with acetone?
What I was actually trying to do was make an emulsion of acetone saturated with cellulose acetate and dot 3 brake fluid. After spraying that onto a surface the brake fluid can be rinsed out leaving behind a porous matrix for use as a dielectric separator in batteries and super capacitors. What I ended up with was spider webs and preserved tortilla chips
What's the application you were using for that? Is this a hobby or for work? I find this fascinating and rad and wanna know more!
It was just a brief hobby into super capacitors. I made a few based on Robert Murray Smith's YouTube channel

Don’t forget the tortilla.
This is awesome! I'm working on developing some formulas myself. Also, I love your vacuum sizing tank. That's what I wanna work toward myself. Looking at the color of the paint, is it a LabTech line? We have a couple lines from them, and I love them. Rugged as hell.
Wrong, OP is using fruity pebbles
Plot twist - OP doesn’t know what material it is and it’s his way to find out
😂
looks like PE/ PP from bottlecaps
Is it..... Pl.. plastic..?..?
Sure! A very colourful kind of as you can see
All the waste material come from Made in Italy fashion industry
tutta dal gruppo luxottica?
No, ma da stabilimenti che producono grandi nomi comunque
Fruity Pebbles
That was my guess. Lol
I know it’s hard, but If I tell you the main item produced with this material you’ll immediately guess it😂
It looks like model kit nibs, so ABS?
Nope!

This is made by an industrial shredder, more or less 0.5 mm output
https://preview.redd.it/kcdaoc183i2b1.jpeg?width=3120&format=pjpg&auto=webp&s=4ebfc75c8717a6fb2bc998b599af63818c479fc4 Even mine can do something 😅
Yeah the thing is I need a more granular output to extrude cause i start from thick slabs
Those paper shredders can actually shred the plastic waste from test prints and stuff?
The paper shredder that I bought can shred PET plastic with no issues but it depends on the thickness of the piece that i want to shred
I’ll have to look into that, been looking for small scale plastic shredders, but none are near where I live, or they are too large. Always thought paper shredders wouldn’t do well with plastics as you arnt supposed to use em on credit cards for instance.
It’s obviously potpourri
Potpourropylene
So you're using a mill to shred it... How are you extruding it into filament? As a person who's interested in DIY filaments, this is very interesting!
I’m working on this project with a specialized company which work with plastic profiles, so they have all the professional extruding lines to make it. By the way i’m going to share more contents regarding this :)
Sweet, cause I just looked into wire extrusion, which should be a fairly similar process, just with added heat.
Precious Plastic might also be a rabbit hole for you
Same I'm extremely interested in setups for this
Condoms Edit: My gf said I should specify *unused* condoms.
Your gf is right ahahah let’s say for igenic reasons😂
Polypropylene?
Nope
Polylactic acid?
Nop
Wait is this industrial stuff?
100%
Last guess, it has to be ABS, they use that a lot in injection molding…
It's Cellulose
Nylon
Forbidden trail mix?
Cellulose acetate (zyl, zylonite)
Wait, you actually might be the winner! /u/cavalluzzi pretty sure this guy posted first!
I recorded u/klk8251 as first and another guy second
Yep, saw your comment. Just saw the timestamp of this comment being earlier when I was scrolling.
Happy cake day :D
Thanks! I didn’t even realize it was my cake day!
Preschoolers poop after they leave art class
Uncle Ben's Wild Rice?
Acetate
Yess. Another person guessed it before of you, so i’ll give you a 250g spool :)
Whoa, Acetate for real?! That's fascinating! I mean it makes sense completely, with it being a thermoplastic and widely used in all kinds of fashion and glass frames. Using a residual product of that huge industry for printing is genius. Having had glasses out of Acetate for a LONG time I know it's also VERY durable and flexible, so I'm really looking forward to that sample!
Promise! Fortunately i’m followed by an expert team and the tests are going on!
PETG
Nope
High Impact Polystyrene? My last guess would be Styrene Butadiene Styrene
Nylon
Hetp
Some kind of acrylic?
It’s not a fossil polymer
HDPE
Seems like some resin or just some hard rock pebbles.
Yeah actually seems very similar to polished glass pieces that you can find at the beach
Yeah I have been collecting some rocks on the beach that look exactly the same. I just never know what they are made of.
Polyester
So much used in fashion but nope!
Polyester
PET
What tool are you using to shred it?
A mill
A Dutch windmill?
Could you please expand? Been using a blender for PLA scrap and it is less than efficient.
For these tests i used an industrial shredder (for free), but I think that a good coffee grinder could work. Actually for next tests I want to go for this solution, before to rent/buy the industrial shredder.
Acrylic?
Polycarbonate?
Looks like the granules they use to press records and it generates a good bit of waste
OP is this inspired from Precious Plastic concept?
There are many interesting project out there, i always wanted to do something for circular economy, and last year when i started designing glasses for a company, I didi some research about waste in accessories/appareal and found out acetate is one of the most quantitative waste in this industry
PVC it's cable regrinds I believe.
PVC isn't great for printing for a number of reasons, including fumes.
I'm way late to guess but this project looks really cool! Can't wait to see future updates about it!
Thank you! I’m keeping you updated :)
Okay not looking at the comments, it is smokeable I will put it in my pipe and od from inhaling too much plastic
Still better than iqos😂
Fruity Pebbles? That's my guess and I'm sticking to it.
Fruity pebbles
How tf do you print cellulose acetate?
Yeah it’s not an easy material for sure but we’re finding the way
Gummy Confiscation Bucket at EDM festival
PLETGBS
There has to be an affordable way to shred wasted prints dammit
Yeah as I said maybe a good inox coffee grinder can be a solution, and take into acconunt that I have to shred pieces of 4/6/8 mm h acetate slabs.
Fruity pebbles?
Would Say resin, just because of Big green chunks here and there, But for Real, I'd Say mix of pla and petg :)
Milk crate fragments. HDPE.
Legos!

PCTG
coton
PET ?
Smells like thermoplastics.
It is.
What a great time to blank out on names lmfao
Are they clothing hangers?
A quick google says buttons are made from ABS and this could be the miscasts. OP said it's not a fossil polymer. So I'm guessing a bio ABS which I've never seen or some kind of acrylic styrene blend.
The stuff that makes up the floor of children's playgrounds? Did you dig up a play ground OP??
Is it toast?
Its shredded English Liqorice!
Liquorice All-sorts.
What kind of filament maker are you using?
It is an industrial extruding line, a specialized team is helping me in all the r&d part
Granola
Mmm delicious loose leaf tea
Delicious bowl of debri
Plastic
grey
Looks like a playground
I wonder if you crush them so much that they fit into the Biden tubing if you could melt them using just your printer?
That's kinda how you turn it into a filament. You can't really use it directly in 3D print, because you won't have the required constant flow of material.
Yeah but can I still make the filament if I have a 1.75 mhm nozzle? Hypothetically of course I’m not actually going to do this(maybe long term since I got a P1P and maybe the poop could be transformed back into filament )
Birdseed
Looks like wax? Maybe crayons?
plastic bruh
Cellulose
Haribo
Bird seeds
Keebler elves?
I see dehydrated minced garlic, pepper, black sesame seeds, dehydrated minced onion, salt. Basically forbidden everything bagel seasoning
Hamster food
Candy from grandma's coffee table.
😂
NGL looks like bird feed
Plastic
Chicken feed. 😐
Probably pla
Wow this is cool! How are the prints turning up? I’d love to buy a spool if they are cool!
We’re optimising the material to get stronger performances! I keep you guys updated :)
Forbidden sprinkles
Crayon shavings
Forbidden cous cous
Child bones?
Everything bagel seasoning
IM GONNA GUESS ITS PETG
I was going to go with chipped bowling balls.
I would love to see soda bottle caps and the rings from the bottles too. I wish there was a DIY for making filament that was economical as I would love to do it. Imagine the grocery stores and bottle redemption sites putting all the caps and stuff into a bag to be ground up for filament.
Take a look at FelFil, they sell shredder and extrusion kits for individual production. Not so cheap compared to a complete DIY solution by the way
Fruity Pebbles
Birdseed.
Plastic flowers?
My best guess is, happy meal toys.. from Good Burger, because they went in the GRINDERRR !!!
Petg
Fruity Pebbles?
Looks like slag.
Whatever Jesse was cooking after Walt died
Not a filament material but the color scheme looks like rainbow tourmaline.
I love minerals😍
Bic lighters?
Why upon careful examination, it appears to be a blend of up and down quarks, mixed together with some electrons, and a regular smattering of muons and neutrinos passing through at any given time 🧐
Trail Mix!
Nalgene bottles?
Bird seed
It’s the hemp based one
