Same here @JeffB Mine has been holding up well. I need to disassemble once more because it’s leaning backward some and I need to fix that. It is stable now and I have very few if any fails. I will post pics of the current state of things a bit later.

The little bat wing brace I put around the back of mine sort of keeps the sunlight out of the vat  8)

But man the whole design to hold the print head is clumsy. The Z rail is so short that it is hard to even rotate the build plate 90 degrees to let it drip off. And every time I end up with resin on my fingers. And I keep bumping the top of the machine and that is getting resin on it. Compared to the OG Photon that I rarely ever got even a single drop of resin anywhere.

Here is the latest.

Front view. I'm calling this version another ridiculous name like the original.
It's going to be called the Mega Mini 4k (Mm4k) the irony!

I've added handles to the case extender ... it's so much easier to take on and off now. Next up is to prime and paint the cover extender.

I painted the arm and end stop silver to better match the stock nature of the machine.

The pretty floral paper is me testing a different gasket height.


I am using the Nintendo switch tempered glass on top of the 2 layers of card stock. The extra glass does take away the details some. I was disappointed by that.
So you can protect your screen or you can have uber tiny details but not both.

How hard was it to drill and tap the  z-axis and the z axis build arm?

I am thinking of doing something similar to what chris did. I don't want to disturb the underside so was going to put a plate on top, brace the z axis and the build plate arm.

Just tense moments while hand tapping into aluminum is all. Aluminum gets gummy so use oil and every 2 turns forwards I back it out a little.

If you make a new metal arm you’ll likely have torque issue from the current motor and leadscreew. Carl from the UK did that and those were the issues he had.

It's been awhile since I've posted about this machine but I am making a kit for the Sonic Mini 4k based on all the work I did to it. I've already got a few beta testers in the UK, Italy, Netherlands and the US running through the kit.


Here's a video of some of the things it's capable of now.

I stopped following the Sonic 4K Facebook, but saw this posted:

So it would seem that even Phrozen thinks the machine is too flexible.

Hmmm...  I get the new bracket, but why the Z-rail/bearing and motor/feed screw?  Did they come to the conclusion that they needed a more powerful stepper motor?

Interesting.  Once I got my unit back together, I'd planned on ordering a spare LCD.  It might be worth it to buy the upgrade too, though I think it should be free!

Yeh ironic right. They're not fixing the real issue sadly. I just got a Saturn (which I am loving) and there is no flex in any of that machine. So there certainly are proper builds.

I had to change my lead screw/motor because I was getting stepped lines in my prints, but still using the same rail. I don't think the rail was flexing, think it was the mount to the base.

I don't know why. And how does any of that bulk up the base plate.


This Elegoo Mars 3 seems to be that same resolution as the mini 4K:  https://www.elegoo.com/products/elegoo-mars-3-lcd-3d-printer

This version of the upgrade comes with ChiTuBox Pro instead of resin:

https://phrozen3d.com/collections/3d-printer-parts-phrozen/products/sonic-mini-4k-upgrade-bundle-chitubox-pro-software?fbclid=IwAR2wkDgYo9OskZyGb7qtPSR6WKPhCZ7a5WwqthV5bjYqtO-LrxqsipEm4iw#specs

I guess ChiTuBox Pro is $169.00 by itself.


Oh and the shipping for the upgrade is $50 yay!  :|

When I upgraded my machine (with my soon to be released kit) I had to reinforced UNDER the z-axis where the z tower connects to the deck. That's where the flex is. The tower itself doesn't flex but the base only below the z-axis connections. The rest of the deck doesn't really flex, just under the z-axis tower.
