Resin tank film problem. I am really disappointed.

Resin tank film problem. I am really disappointed. I received my printer the day before yesterday. And I printed 6 times yesterday and today. But not one was able to get satisfactory results. There is no printed output that matches the 3D file.

I do not know whether it is a resin problem or a printer problem. Especially when printing, resin sticks to the resin tank film and badness occurs. What’s the problem? Is there a way to solve this problem?

For reference, this is not a damage caused by peeling off the resin lump placed on the film.
The film seems to consist of several layers. As the resin penetrates through the first layer and grows in it, the film swells up.

The resin tank film was damaged at the second output. So I ordered the resin tank again for $ 59 at the UNIZ site. It is too expensive. And it does not sell film separately.

I had the same problem with the tank film ripping after my second print. I’ve contacted Uniz about the quality of the resin tank film and they said they are supposed to last for months. There is no way they will last that long. I asked about having an option to purchase the film replacements and they won’t do that. You’re better off buying a roll of FEP film and replacing it yourself. It’s fairly easy to do and will save you money in the long run, at least until they come up with a better option.

The film of the resin tank is not transparent. However, the FEP film is completely transparent. Is it okay to use it?
Have you ever used FEP film in SPLASH OL?

Yes I’ve been using FEP film from flexvat.com and it works just fine. I have the Slash+ UDP but all the Slash printers basically work the same way. There is a foam cut out on the bottom of the new resin tanks that I believe helps create a vacuum which you won’t be able to replace. I’ve been able to print fine without it.

Just got a pinhole leak in my film after about 3rd print.  I’m going to assume I didn’t get all the crud out from the last print, since when I did then pre-clean exposure, it did almost nothing…very brief exposure over whole screen that didn’t polymerize.

I’ll try the flexvat approach, since I’m not paying another $60 for something that should last longer than 3 prints.

With my UNIZ Slash, the film also becomes permeable (porous). Possibly I will buying a roll of FEP film and replacing it, as you proposed, Brian. I read that the FEP film should be at minimum 0.127mm (127 micron) thick. I also read that UNIZ tanks use 0.15 mm (150 micron), but I don’t know if that’s really correct. What do you think, what is the best thickness for FEP films for UNIZ Resin Tanks?

And is there somewhere a guide on how to replace the film or do you have any tips?

Can you post the settings of the prints? and did you reset Z axis when you find that the cured resin stick to the film? BTW, you should clean solid residue up before next printing.

Jangick on October 11, 2018

I have reset Z axis. I tried to print again. Below are the printer settings for printing. And the result.

 

What’s wrong with my printer?
And is it true that there is DRM on the resin? I have not seen anything about DRM when investing in a printer in a kickstart.
I bought a new resin in Korea for $ 100(I live in Korea). If the resin is DRM and can not use the new resin, it is a big problem for me.
If I can not use the new resin, I would like to get a full refund.

Hi, the Eiffel tower does not suit to be printed in UDP, because there is a big section in it, and you can print it in normal mode without any support.

There is an RFID limitation in slash OL and pro OL, and it’ll be canceled in firmware version 4.4.

This is exactly what happens when I go to print the eiffel tower, either in UDP or non-UDP mode.  I assumed since you demonstrate UDP mode in your sales videos using this model that the model should be suitable for this mode.

Hi DP,

What would be the possible cause of the pinhole leak? Would you say the resin tank will be able to handle more than 10 prints if everything was set up alright? Appreciate your feedback, also what do you think of the resins tank, did the non metal structure degrade over time due to contact with resins?

@Uniz Support, So after the 4.4 firmware update, we will be able to use 3rd party resins? Also, will we be able to pour in the resin from the 3rd party bottle instead of using the proprietary bottles and resin pump?

Evan on October 12, 2018

Also, do you have an estimate on when firmware 4.4 will be released?

Uniz Support on October 15, 2018

Yes, the firmware 4.4 is under test, and it’ll be released soon.

Incompreensible!!!!!!! are uniz working to send us a vat with a permeable membrane like carbon3d or similar machines thats works fast and really well????

Uniz has fast resines, but we need an good membrane to do the works correctly and fasts!!!!!!!!

 

Freddie on July 2, 2019

Hi Fernando, 

Have you heard any feedback from Uniz ? I am trying to understand more about this pinhole leakage problem and if the machine can used to print out 100-500 parts per month, is it reliable enough?

Actually, UNIZ have a patent that deals exactly with carbon3d like membrane. The difference is that Carbon have a solid oxygen permeable and UV transparent plate in their vat. Uniz on the other hand has a membrane (FEP ) that is a bit above the LCD. This way the oxygen can get between the LCD and film. At least this is the patent :-). Now achieving this is another story! Carbon solution uses DLP which is far away from the “window”, therefore there is plenty of space for oxygen to go through that window.  And that window is from hard material. I don’t think that UNIZ did put in the production their patent yet. 

So there is no oxygen permeable film/membrane yet. Just a plain FEP film. If I’m wrong someone correct me.
