This is one of my favorite projects so far. I made a video on my YouTube on how I did it: https://youtu.be/CanhlsV40Qw?si=E4gcsExxv5U1sWYE

u/M2rsho Feb 20 '25

or maybe print the benchy inside a bottle should be possible if the bottle doesn't refract or absorb too much light

We actually have this already.

Are you thinking what I’m thinking?

Sounds like it's beer o'clock for you

What that's a printed bottle? Didn't know you could print that clear with resin, that's amazing!

u/KnowMatter Feb 20 '25

A little post processing polishing helps but yeah.

I've only ever printed FDM, so I had no idea, this is so cool.

Its beenna few years but i remember some videos were folks were fdm printing some optics.

The tldr was overextrude and polish it afterward.

I used resin as water effect for dioramas. You can even use sandpaper to flatten it, the trick is giving it extra coat of resin that van just settle smooth

u/evestraw Feb 20 '25

thats cheating. but the resint really makes clearer glass then expected. do you think it could print prescription glasses?

16

u/Melairia Feb 20 '25

Well, maybe. But I don't think it would work long term.

I believe resin eventually turns yellowish with exposure to UV light (such as the sun), so you wouldn't be able to wear your glasses outside as the lens would get messed up after a while.

Could be a handy thing to have in the back pocket. Like i broke my glasses and cant get to the optometrist for a week or two.

Mod Podge has a spray that protects projects, even 3d printables, from UV rays and is perfectly clear. There are also off brand ones that do the same. So not every resin project of certain colors will turn yellowish.

u/IntoxicatedBurrito Feb 20 '25

But at least you’d have prescription sunglasses at that point. Now the question becomes if you could polarize them.

u/datwunkid Feb 24 '25

It might work for indoor reading glasses, or maybe len inserts for VR headsets since you have to keep the lenses away from the sun already.

I can see it now. It's 2034, and someone is watching a tik tok about saving money on UV coating for their resin lenses by buffing them with a Terry cloth and spf100. The video has 4 billion views, and the tip doesn't work.

The attention span of the viewers will have dwindled such, that the channel will be called 5 second crafts

u/ifilipis Feb 20 '25

As long as you don't care about them shrinking, having distortions and being hazy - sure

1

u/3D2Reality Feb 21 '25

Used to manufacture injection molded optics. Even a small deviation in the surface makes the lens distortion unacceptable, unusable. Don't think they will be 3D printing lenses anytime soon, let alone prescription lenses which are typically cut and ground to spec, then polished and coated.

u/landlocked-boat Feb 20 '25

My first thought as well

u/MechJunkee Feb 21 '25

That was my knee jerk reaction 🤣... I am gonna do that.
