Resin 3D Printer Reviews & Comparisons: What You Need to Know

So, you’re thinking about getting into resin 3D printing, huh? Or maybe you’re just trying to figure out if it’s worth the hype. Either way, you’ve landed in the right spot. This ain’t your grandpa’s FDM printer – we’re talking serious detail, smooth finishes, and a whole new level of possibilities. But with that comes a learning curve, and honestly, a bit of a mess sometimes. But hey, aren’t all the best things in life a little messy?

What’s the Deal with Resin Anyway?

Let’s cut to the chase: resin 3D printing (also known as stereolithography or SLA) uses liquid resin that’s cured by light. Think of it like this: instead of melting plastic filament like those other guys (FDM printers), you’re using a UV light to solidify liquid into solid objects. This lets you create way more detailed and complex objects. Jewelry, miniatures, dental models? Resin printers eat that stuff for breakfast. Now, that’s something, isn’t it?

Why Choose Resin Over Filament? (Or Vice Versa?)

Okay, big question time – why go resin when you could stick with filament? Well, it really boils down to what you want to make. If you’re all about big, strong, functional parts, filament might be your jam. But if you crave extreme detail, smooth surfaces, and the ability to create very small objects… resin is where it’s at. Here’s a quick rundown:

• Detail: Resin wins, hands down. We’re talking microscopic levels of detail.
• Surface Finish: Again, resin. Filament prints often have visible layer lines.
• Strength: Filament can often be stronger, depending on the material. Think functional parts.
• Cost: Filament printers are often cheaper to start with, but resin printers are coming down in price. Resin itself can be pricier than filament, though.
• Ease of Use: Both have their quirks. Resin requires more post-processing (washing, curing), while filament needs more tinkering to get print settings just right.

Honestly, it’s like choosing between a motorcycle and a pickup truck – both get you places, but they’re designed different things, you know?

Types of Resin 3D Printers: A Quick Guide

Alright, now let’s break down the different types of resin 3D printers you’ll encounter. There are a few flavors, each with its pros and cons.

SLA (Stereolithography)

This is the OG resin printing tech. SLA printers use a laser to trace and cure each layer of resin. They’re known for incredible accuracy and smooth finishes, but they can be a bit slower than other types. Here’s the thing about SLA that can be a pain: It can be slow and expensive.

DLP (Digital Light Processing)

DLP printers use a projector to cure an entire layer of resin at once. This generally makes them faster than SLA printers and can lead to decent results. DLP is something worth looking into when it comes to resin 3D printers today.

MSLA (Masked Stereolithography)

MSLA, which is also known as LCD-based printers, uses an LCD screen to mask UV light, curing an entire layer simultaneously, like DLP. The biggest advantage here? They’re typically more affordable than both SLA and DLP printers. They’re the newer kid on the block, but they’re making waves for good reason. It’s a pretty good combination of cost and speed, really.

Top Resin 3D Printers of 2024: Our Picks

Alright, time for the good stuff – which printers should you actually consider? Keep in mind, this is just a snapshot, and the “best” printer really depends on your budget, needs, and what you want to create. But here are a few that are consistently getting good buzz.

For the Budget-Conscious: Elegoo Mars 4

If you’re just dipping your toes into resin printing, the Elegoo Mars series is a great starting point. The Mars 4 offers excellent print quality at a price that won’t break the bank. It’s user-friendly, reliable, and produces surprisingly detailed prints for the price. A great beginner’s option!

For the Detail Obsessed: Anycubic Photon Mono X 6Ks

Want to capture every single tiny detail? The Anycubic Photon Mono X 6Ks is known for its high resolution and ability to produce incredibly sharp prints. It’s a favorite among miniature painters and jewelry makers who demand the best possible detail. It’s really, really impressive.

For the Speedy Pro: Phrozen Sonic Mighty 8K

Got deadlines to meet? The Phrozen Sonic Mighty 8K is all about speed, without sacrificing too much on print quality. Its larger build volume is also a plus if you need to print bigger models. It’s a powerhouse, plain and simple.

Resin Printing: The Good, the Bad, and the Smelly

Let’s talk about the realities of resin printing. It’s not all sunshine and rainbows; there are a few things you need to be aware of.

The Upsides:

• Incredible Detail: We’ve hammered this home, but it’s worth repeating. The level of detail you can achieve with resin is mind-blowing.
• Smooth Surfaces: Say goodbye to those layer lines! Resin prints come out smooth and ready for painting or finishing.
• Complex Geometries: Overhangs, intricate details… resin printers can handle it all (with proper supports, of course).

The Downsides:

• The Smell: Some resins smell, well, not great. Make sure you have proper ventilation. Honestly, some of them reek.
• Post-Processing: Resin prints need to be washed and cured after printing. It’s an extra step, but it’s essential for getting the best results.
• Resin Disposal Considerations: Cured resin waste must be disposed of properly. Regulations may vary, so make sure you adhere to your region’s protocols.
• Resin Sensitivity: Resins may cause skin allergies or irritation. Be sure to wear the appropriate PPE, such as gloves and eye protection.
• Fragility: Some resins can be brittle, especially the cheap ones. So consider that when selecting resins.
• The Cost: Resin can be more expensive than filament, especially for specialty resins.

Setting Up Your Resin Printing Workspace: The Essentials

Okay, you’ve got your printer, now what? You’ll need a few key things to create a safe and efficient printing space.

• Ventilation: This is non-negotiable. Make sure your printing area is well-ventilated to avoid breathing in fumes. A fume extractor is a great investment.
• Gloves: Resin can irritate or cause allergic reactions, so wear nitrile gloves whenever you’re handling it.
• Eye Protection: Safety glasses or a face shield are a must. You don’t want resin splashing in your eyes.
• Isopropyl Alcohol (IPA): You’ll need this to wash your prints after they come off the printer. 90% or higher is recommended.
• Curing Station: This uses UV light to fully cure your prints and make them stronger. You can build a DIY one, but a dedicated station is much more convenient.
• Paper Towels: For cleaning up spills and messes. And trust me, there will be messes.

Think of it like a mini-lab. Safety first, always!

Resin 3D Printing: Troubleshooting Tips and Tricks

Okay, let’s talk about the inevitable – things going wrong. Here are a few common problems and how to fix them.

Prints Not Sticking to the Build Plate

This is a classic issue. Make sure your build plate is properly leveled and that your resin is properly exposed. You might also need to increase the bottom layer exposure time. Sometimes, it’s as simple as giving the build plate a good cleaning with IPA.

Prints Cracking or Warping

This can be caused by a few things, including insufficient supports, improper curing, or using too much force when removing the print from the build plate. Try adding more supports, adjusting your curing time, and being gentle when removing the print.

Layer Separation

Layer separation can be caused by under-exposure, low ambient temperatures, or issues with the resin itself. Try increasing your exposure time, warming up your printing area, or using a different resin.

The learning curve with resin 3D printing can be steep, but don’t get discouraged! It’s all part of the process. The more you experiment, the better you’ll get.
