Vat film and secondary film section

Just because this has been bugging me, I’ll go ahead and ask: is this secondary film supposed to be there underneath the vat film? Is it supposed to be on the bottom? Is it to protect the lcd?

This is not the lcd protective film, I removed that from the lcd when originally unboxing and setting up the unit.

 

Thanks!

I would appreciate a reply from Uniz on this. Is it supposed to be there?

Yes, it’s like something double sticker which sticks to the LCD, to be helpful for the separation between the print and the film.

Really??! Are you joking me?

The double sticking layer has to be there while printing?

Oh God! Why this information is not in the manual?

Its vital information.

Without it the peeling has to be much worst! Am I right?

You have to inform people about important things like that.

I did not notice this film, because it stayed sticked to the LCD protective film, so I removed it with it !!!

Now this double sticker is a bit dirty, how I can clean it? Or where I can buy new one?

Thanks

Don’t worry, with it, the peeling has to be much better. Without it, it’s not a big problem.

If you say so. But its a little confusing. If with it is much better, then it should be there.

I will try to put it back to see the differences of the peeling. I will report it here.

Anyway, thanks for the reply.

I’m glad I read this thread. It shows that the support people at UNIZ are dishonest. That double sided sticky film ensures the Slash OL can’t work. It is not supposed to be there. NOT AT ALL!!! Why on Earth would you want to stick the bottom of the polymer to the glass? It does not make sense! Nor does sucking the polymer with a vacuum towards the glass during regular peel mode. When the bed raises it is supposed to pull the film upward and stretch it. The stretch allows the peel. This shows that UNIZ does not understand how it is supposed to work. This is not a viable 3D Printer. The lead “Engineer” at UNIZ should be immediately fired.

There are two modes one for UDP and one Natural Peel. The latter should work as you describe. With UDP mode there should be little or no flex in the vat in order for it to work properly. I assume the pump is off when in Natural Peel. Have you tested this? I don’t have my Slash OL yet so I can’t verify it. I must say the Slash Plus I have is working well though.

Take the resin out of the vat and remove the bed. Print a small object with no resin in the vat and watch. The vac is turned on just as the print starts in both UDP and Peel modes. It sucks the vat polymer flat and tight against the LCD glass. Add to this the unfortunate fact that someone at UNIZ added a double sided sticky film under the vat and the people at UNIZ have gone way out of their way to make the Slash OL inoperable. I removed the double sided film (VERY carefully!) and I CAN get this thing to work in Peel mode, but not very reliably. I had to rough up the bed, increase the 1st 3 layers to .2mm and set the 1st 3 layer exposures to the max to get it to work. However, the smaller the area for the layer the less likely it will work. UNIZ SW generated supports? Forget it. I cannot get them to stay stuck to the bed. The only prints that work are prints with thick supports I manually added using another application.
