Thank you

[@dtj9923]

It's so funny to see your boxes of labeled test prints. I feel much less crazy now! I also have piles of carefully labeled and sorted calibration print samples sitting on a storage shelf for all of my machines and resins. So far I haven't had any print quality issues with the black tape installed, my 8K has been pretty much perfect out of the box printing layers as tight .02mm layers. The Phrozen 8K Mini is hands down the best printer I have ever owned. Truly amazing prints. Great video as always! I learn something every time I tune in.

[@Necroxin]

Your videos have been an absolute lifesaver for me since I just got back into 3d printing! Spoke with you for just a tiny bit in a FB group as well! Was wondering if it'd be possible to make a video about supports? Like ideal sizes of the supports, where and when to use certain ones, etc? I know there's tons of videos out there on it, but your videos are the ones that really got my printer working with such great quality, so I trust you more on it all lol

[@wangdennys]

Yes i am planning to. But since support has a very wide range of variation I am thinkin of making series video of it

[@SHwoKing]

Cross pattern, FEP frequency, it's like viewing a drum tuning video :D.

[@wangdennys]

well i never install my fep with tuning the frequency, i did it only for the sake of argument. LOL

this was extremely helpful. I'm considering buying one of these and I appreciate all the time you put into troubleshooting the issues.

do you know if the newer firmware update for the mini 8k resolves the z calibration issue with the tape? SHould I remove the black tape still if I'm using 2 paper to calibrate?

OMG I feel like I am in 3D Printing Masterclass. Man, you are my Hero :)

[@K.V.S.H]

Great video ! Is there a way to correctly do the compression test without a digital calipers for mesuring ?

[@garymiller9449]

Thank you for the review. I learned a lot. I measured the thickness of the black tape on a SOnic Mini 4K. When you measure two layers of black tape overlapping on corners it totals 3 to 5 times the height of a single Z layer. Then add to that the build plate itself is not perfectly flat. They do not trim the tape so that it does not obstruct the contact with the build plate. So it is not possible to have the FEP flat and parallel to the screen and the build plate all on one plane. It is all I can do to stop myself from using some really bad language. How hard can it be to attach a screen flat onto a surface? Why would anyone expect overlapping layers of tape to be trouble-free?

[@wangdennys]

I feel you 😆

[@Bledoston]

Great video as always! Thanks for taking time to figure these things out.

[@sergiogiusti456]

HI Dennis how thick is the yellow tape that you used in sostitution of the black original one? I understood that is clapton tape is it trow? and overmost the tape in the square is superimposed, so it doesn't create a double thicness where the tank touch the plane? CiaoSergio

[@timothywood4402]

Hello Dennys, could we use 3M Scotch tape ? As the mono screen is not directly under the FEP but a glass plate is. The point being to stop resin from getting in the housing . What are your thoughts my friend.

[@wangdennys]

Still better option is kapton tape To minimize thickness and it also block uv very well

[@joerie.houthuijsen]

Dennys, english is not my first language, so forgive me if i aks something verry logical. Can you tell me a bit more about the black tape and your tape? - i mean, you install a mat screenprotector on the schreen (inside the black tape)? is the tape still higher then the protectore then? - if you remove the blakc ape and ude 2 rows (slightly overlap) what is the difference in hight then ? of how can that be such a difference ?

[@wangdennys]

Honestly No idea the why overlap kapton tape is fine But not the black tape. LOL I did print full plate and place object at the corner where the kapton tape overlap But it still come out fine. So i cant really explain it. But it just works. 🤣😂🤣😆

[@gerardsmurf6298]

Great review! But what surprised me to see is that the build plate of the 8k is wider than the 4k one. The specs on the Phrozen site state the print volume of the 8k is L16.5 W7.2 H18 cm, and for the 4k L13.4 W7.5 H13 cm, so the 4k should be wider right? (7.2 vs 7.5) But in your video the 8k one looks longer *and* wider. I also checked the parameters in Chitubox and Lychee, there they also use 7.2 width for the mini 8k. So that's really the print limit? even though the build plate physically is wider?

[@wangdennys]

Build plate can be wider It is different from build size. And as always, build plate will be slightly longer and wider compare to build size

[@netnoob77]

Another very interesting review. :) Every video I learn something new about 3D printing. It's really a pity Phrozen products seem to have issues right out of the box. Mini 4k had issues, now Mini 8k. Frankly, as a newbie to printing, I wouldn't know how to troubleshoot if I see those print lines. However, thanks to your testing and troubleshooting, new Mini 8k owners have some potential solutions. Separately, an observation. Correct me if I am mistaken, but if I recall correctly, Mini 4k had better light uniformity as compared to Mini 8k.

[@wangdennys]

Well they are budget printer after all But wait for the part 2, you will figure out if it worth it or not when you see the print result. Mehehehehehe

[@netnoob77]

@@wangdennys I am sure it prints very well after your troubleshooting. So far, other reviewers have indicated that there has been a noticeable increase in detail / crispness of prints, especially with the 8k resin. As for the price, the Mini 8k is considered pretty pricey. My Photon Mono 4k is less than 50% of its price. :)

Hi Dennys, Thanks a lot for sharing your experience. Just an information ; for my mars 3d printer i need to put 8 sheets of paper (8x0.09mm) to counter compression effect. Now "disk compression.stl" and "Compression Steps Test 1.stl" are perfectly printed ! Regards

[@paintroll2079]

Great video man:) where did you get that head? would like to test print my new phrozen sonik mini 8k

[@Cakemagic1]

This is interesting and maybe it would explain why my prints always have massive compression on the first minimeter or so. I might have to raise the build plate a little bit and test out.

[@TunneLVisioN42]

What should be the 3 measurements for the steps in the compression disk? Lychee says overall height is 2.10mm but curious what the other steps should be. is it .10, 1.10, and 2.10?

[@joe_ferreira]

You could use a right angle USB extension cable to bring the port to the front.

[@wangdennys]

the usb port is already at the front, only the power button that is at the back. but usb extension will a good idea for other printer that has usb port at the side

[@banglavsky3243]

Currently, after your review which printer do you recommend, this 8k or the other 4k? Is the sonic 8k really worth that price? I plan to use it for jewelry.

[@wangdennys]

We shall see on part 2 ok

[@brendon6930]

Kind of confused me how the black tape was causing the FEP to come loose after you already tightened it.

[@wangdennys]

No The screen is not glued to the platform. And the blacktape is kinda flexible, causing the screen move while printing. Kapton tape more rigid and hold the screen in place well.

[@brendon6930]

Would the same thing happen with the Mighty 8k. Cause I still have the black tape from phrozen around the screen

[@dewdropjewellery2535]

Thank you for sharing. Very detail.

What castable resin do you recommend for this printer, one that will make use of 8k capability and print at 20microns? I think current Phrozen castable resin is meant for 30-50microns

Ah I figured out why I have a massive hard time figuring out the compression and all on my Mono X; it's because the Mono X has this dumb 10 transition layers that you can't turn off. So the the 10 layers after the burn in layer will always be overexposed and throw off all the compression tests.
