Anycubic Photon Mono 2 Review

Though the vast majority of hobbyist 3D printers available today are FDM (fused deposition modeling), as the 3D printer market grows, resin (also known as SLA or stereolithography) printing options like the Mono 2 continue to hold their popularity with certain crowds. Super detailed, but smaller prints generally align with SLA technology better.

Performance Comparison

Print Quality

We hit the ground running with our most highly weighted metric and what sets SLA printers apart — Print Quality. Without going into too much detail (more here), SLA printers work by flashing an image via a high-resolution screen, layer by layer, to cure a goopy, raw resin into a 3D structure. The resolution here fundamentally beats the resolution possible via melted plastic through a nozzle (FDM), resulting in more detailed prints with fewer errors.

Indeed, in this respect, the Mono 2 is among the best-scoring machines in our lineup. Delicate, hyper-detailed prints are within reach, as shown in our lattice skull test. When looking for things like poor surface quality, overhangs, and bridging over long spans — common problem areas with FDM printers — our testers say, “These are all nearly nonexistent issues for the Mono 2; gravity is much less of a factor here.” Intricate prints are not your concern; that said, size (and material cost) might be.

A support structure is still needed with some fragile geometries, though, and again, the Mono 2 shines here. Supports break away easily, and the surfaces where they were attached show barely any signs of their existence.

Ultimately, the benefits of resin are clear when evaluating our classic Benchy print (the standard tugboat design used throughout the community to suss out issues and evaluate quality). We're hard-pressed to find any flaws. We will note that print times are considerably longer here than in other tested machines — 175.5 minutes to print vs. the group average of 74.9 minutes.

Ease of Use

There's a lot to say about our hero, the Photon Mono 2, in this metric. Setup is easy, both on the physical machine and when getting your prints ready through the software side of things. But, according to tester Graham Faulknor, “the post-curing process is nothing less than a pain in the butt.”

A 6.4 out of 10 score (just slightly below average) reflects this major dichotomy. On one hand, we have nothing but wonderful things to say about the setup out of the box. We needed a mere 11 minutes, just about the fastest we've ever tested, to get the Mono 2 up and running. Removing the packaging, installing the screen guard, and quick leveling of the main platform are the only steps needed.

The slicing software, Photon Workshop, is also a joy to use. It's simple, with relatively few settings to adjust (inherent with SLA), and thankfully, Anycubic doesn't try to make it more complicated than it needs to be. A small touch screen on the unit is included as well, which we do wish were a fair bit bigger to avoid the rogue fat finger press.

So Anycubic has made the parts of the process they can control relatively painless. But the other side of the coin is the post-processing of your beautiful prints. This is something we have not seen any consumer-level resin printer manage to do well or even really attempt to automate. The resin itself is a thick, smelly, sticky mess. It can be left in the tank for a few months between prints as long as the UV blocking cap is securely in place, but emptying it for longer storage is a tense procedure.

After a print is done, the bed raises and drips the majority of the uncured stuff off. The print then needs to be washed and cured with UV light in a separate chamber. Anycubic, of course, sells these kits separately — a cleaning kit and an upgraded combo wash and cure chamber. With some practice, this whole process can be done relatively quickly, cleanly, and reliably, but anyone considering a resin printer needs to be aware of what they're getting into.

Print Capabilities

Resin printers tend to have build volumes on the smaller end, and the Mono 2 follows suit with build dimensions of 143mm x 89mm x 165mm (roughly 124 cubic inches). Beyond that, our testing found that the largest X/Y dimensions the software would allow is actually a fair bit smaller at 137 x 80mm — almost 14% smaller than advertised.

Essentially, a model no bigger than 3.15" in the smallest dimension is possible on the Photon Mono 2. The LCD screen resolution is 4k (4096 x 2560 pixels to be exact), but if we're being honest, that's on the low end for printers these days.

One thing we like is that the Mono 2 doesn't get stuck in the proprietary materials trap, and it supports most resins available on the market these days. Resins are continuing to evolve slowly but surely, and having access to water-soluble, plant-based, and ABS-like options is really nice.

Support

Anycubic is another Chinese manufacturer in the 3D printer space, but it has been around longer than most — their first 3D printer was released in 2015. Thus, their support library and materials are mature and cover pretty close to everything you could want to know.

The Mono 2 manual is available online through their comprehensive help center and a dedicated wiki is available for anything else you may want to know. The manual is relatively short and sweet, with much of the space dedicated to dialing in settings and troubleshooting, which goes to show how simple and easy it is to use this product.

We couldn't find a live phone number to call. Like many offshore companies, email contact is the standard, and they usually get back within 24 hours. A standard 1-year limited warranty is extended to all of Anycubic's products, as well as a 14-day no-questions-asked or 30-day sales-determined return window.

Should You Buy the Anycubic Photon Mono 2?

For a resin printer, the Mono 2 is a very affordable, very capable option. No muss and fuss; it works as advertised and without any glaring concerns. The favorite Dungeon Master or Warhammer enthusiast in your life would be thrilled to get their hands on the Mono 2 if they don't already have a printer at home. A more casual user may prefer the ease and cleanliness that an FDM option provides, though.
