Review: Phrozen Sonic Mighty 8K MSLA Resin 3D Printer

New Phrozen Sonic Mighty 8K The MSLA (masked stereolithography) resin 3D printer is now available for purchase. The folks at Phrozen were kind enough to send me a unit to review so I can help you decide if this is the printer for you.

Disclaimer: Phrozen provided me with this printer for free, but this review is as unbiased as possible. Phrozen did not pay for this review and these are entirely my own thoughts.

MSLA resin 3D printers has grown in popularity in recent years as better LCD displays have allowed larger build volumes with better resolution. These printers offer much better fine detail reproduction than filament-based 3D printers, usually at the expense of build volume. But the new Phrozen Sonic Mighty 8K has a pretty generous build volume, which means there’s not much to sacrifice.


  • Build Volume: 218 x 123 x 235 mm (8.58 x 4.84 x 9.25 inches)
  • XY resolution: 28µm
  • Maximum print speed: 70 mm/hour
  • Interface: 5 inch color touch screen
  • Connectivity: USB, Ethernet and Wi-Fi
  • Z axis: dual linear rails, lead screw
  • Software: Chitubox or third party

First impressions

As with the Phrozen Sonic Mini 8K that I tested 6 months ago, I was impressed with the build quality of the Phrozen Sonic Mighty 8K. Phrozen models tend to be a bit more expensive than competitors like ELEGOO and Anycubic, but they feel sturdy enough and well built.

The design of the Mighty 8K is minimalist, but attractive. You can see the quality of components like the linear rails, which are ground for straightness. When powered on, this large 5-inch touchscreen comes to life with a beautiful high-resolution interface.

The build plate has an interesting laser cut box pattern that makes partial grip easy. This will leave a slight indentation on the parts, so be sure to use a raft if you don’t want it showing on finished surfaces. The build plate attaches via four four-tier screws, which feel secure. The entire build plate attaches to the Z axis with a massive thumbscrew, making it easy to remove and replace.

The aluminum tank is large and has a removable frame, which means you can replace the FEP film when it wears out. Some MSLA resin printers today have vats with permanently attached FEP film, which makes replacement more expensive. This is not the case here, fortunately.

Everything is as it should be, that’s what I expected from Phrozen.

Connectivity and webcam

The Phrozen Sonic Mighty 8K offers three ways to transfer sliced ​​files: USB, Ethernet, and Wi-Fi. ‘printer. USB is what I used for all my testing.

But you can also connect the printer to your local network via Ethernet or WiFi. If you do, you can transfer files to the printer’s internal storage over your network. My printer is right next to my desk, so I didn’t feel the need to use this feature. But I’m sure some people will like it. However, these people should be aware that WiFi connectivity is via a USB dongle that plugs into the same USB port that one would use for a USB drive.

As a surprise perk, Phrozen has also added a webcam to the Sonic Mighty 8K. Although the camera is present, it is not yet functional. Phrozen tells me that they will provide an update in the coming months to allow users to take advantage of the webcam. Presumably this will allow remote print viewing and time lapse captures.

Software and resin

While Chitubox is the official slicing software for the Phrozen Sonic Mighty 8K, I chose to use Lychee Slicer. This printer is compatible with third-party slicing software, so users are not locked into the Chitubox ecosystem. Whenever possible, I prefer to use Lychee Slicer and so that’s what I did for this review.

Like most MSLA resin 3D printers, the Phrozen Sonic Mighty 8K is compatible with all 405nm resins. But Phrozen developed a resin specifically for their 8K printers, which is what I used in my review. According to their marketing, Phrozen Aqua 8K resin is formulated to provide better results at these high resolutions.

I did all my test prints using the default settings, which print at a standard layer thickness of 50µm. I had to get help from Phrozen to adjust the settings in Lychee Slicer, as I had occasional issues with first layer adhesion. After changing the settings according to Phrozen’s recommendations, these problems disappeared.

Print results

The print quality of the Sonic Mighty 8K is simply phenomenal. This 28 µm XY resolution really shows. The surfaces were smooth and I couldn’t detect any resolution artifacts. Tiny and fine details appeared crisp and clear.

The quality of an MSLA 3D printer is not just a function of XY resolution. Light uniformity and bleed are also factors. The UV LED light engine and LCD display affect these. In this case, I could see no indication of problems caused by either.

Simply put, the print quality of the Phrozen Sonic Mighty 8K is as close to perfect as I’ve seen on any MSLA resin 3D printer.

As a bonus, the build volume is substantial. It’s not as big as your average FFF (Fused-Filament Fabrication) 3D printer, but it’s close. This means that it is possible to print quite large parts while maintaining incredible surface quality and detail.


I always try to find negatives to say in these reviews to make it clear that they are honest. But I can’t make a single complaint here.

It might be nice if the build plate didn’t have a pattern, because it reflects on any part surface that touches the build plate. But that seems like a very minor concern, as the standard resin printing advice is to tilt the parts on the raft supports anyway.

I have no qualms recommending the Phrozen Sonic Mighty 8K to anyone looking for a mid-range MSLA model. This will be my primary resin 3D printer from now on, as the balance between resolution and build volume is ideal for my applications.
