And, I would definitely recommend the 3D printer, I think it is the best purchase I have made in recent years…For charity, you have to know how to set it up well, know how to use CAD programs for 3D modeling and have a minimum of engineering criticism in order to create light but at the same time resistant components, but for the rest it is very useful ... I print everything.. To give an idea of prices, suffice it to say that per piece whose printing time was approximately 5-6 hour, the quote made to me online by a firm was around 300-350 Euro, while I paid for my printer in total 205 euro. It arrived in kit form and I had to assemble it entirely, however it was not a problem and today I am fully satisfied with it…
Hello Marco,
I just read that you've also done finite element simulations, of the structure of the blank that you would like to obtain…You would show some results?
Or the results of the various configurations you have tested (if you have tried more than one)?
thank you, it would be very interesting… As for the tensions within the blank, the article that Giulio posted to you is very valid ...
These are the tests I had done on my blank once I got out of the oven:
To obtain images of internal tensions, I put the blank in front of the completely white screen of the home TV (ok TV, PC screen, etc ... but not the screen of old cathode ray tube TVs)
The completely white screen was obtained by sending a video of a couple of minutes found on youtube.
After that, just look through the glasses for 3D movies, they also give you to the cinema, to see the states of tension in the glass. You have to figure out which is the right way to put your glasses though.
I'll explain.
if you look at the first image you will immediately notice that the screen is in the background (that of TV) it is white and can only be seen on 4 position the internal tensions at 90 ° from each other, but this is not the correct position to place the glasses.
If you start rotating your glasses, you will always see the white screen and those 4 colored areas turn with them, until you get to a point, where the TV screen suddenly changes from white to black, as in the image below.
Here is the correct position to observe the tensions.
In the specific case, as you can see there is a kind of dark cross in the center, which I think is due to some phenomenon that does not depend on the blank because it remains identical, in the same position, even if I rotate the blank.
What is of interest instead, it is that blue-blue circular area that extends up to 3/4 the diameter (constant voltages or not present in this area) which then, it fades first through white until it turns yellow. This shows me, than that chromatic variation, is due to internal tensions, but to be honest, I would not know how to evaluate its size. It may well be that the tensions are small and within a far more than acceptable limit.
To get the pictures you saw, I had to place the glasses upside down, that is, with the arms facing forward, because if I put them "straight", that is, with the temples facing the observer I always saw an image of this type:
and I could never find the position for which the screen behind it was black.See you soon and good work…ciaooo

Hello Marco,
to tell the truth since it broke, I never wanted to know anything, I haven't even thrown it away yet, it is still there on its supports…
Anyway, in the first analysis, it does not seem that the break was due to those residual tensions… http://assetabeta.altervista.org/Tecniche/vetro/850/stampo.html
