It’s been a few years since the first affordable desktop resin 3D printers hit the market, and the offerings of both printers and resins have only increased since then. If you’re a newcomer to resin 3D printing, it can be a bit confusing and even overwhelming to find a suitable resin for your printer and specific project.

Resin printers are famous for the high level of detail they can attain, which is why they’re popular for printing miniatures and jewelry. Additionally, they can be used in certain industries like dental, which require highly accurate molds or prints.

Broadly speaking, resin is a liquid material that reacts with UV light, causing it to solidify. It is formulated with monomers (which form polymers), oligomers, and additives, which manufacturers are rather secretive about. These ingredients cure into a solid photopolymer with exposure to light.

Because of their chemical composition, it’s important to ensure safety when working with resins. A mask and gloves are always recommended, as resins emit toxic fumes and aren’t good for your skin, especially with prolonged contact.

In this article, we’ll go over the most common types of resin while also presenting some popular options for each category. But first, a bit more on resins.

The Best 3D Printer Resins – Buyer's Guide

Choosing the Right Resin

Most resin 3D printer manufacturers include a bottle of resin alongside the machine, but once that (often small) sample is gone, the question arises: which resin should I get?

If you’re a beginner in resin 3D printing, the most sensible decision is to go with the resin made by the printer’s manufacturer. This will make it easier, as manufacturers often provide print settings that are proven to work with the specific hardware and resin combination. However, there are other resin manufacturers that produce amazingly good products, so it’d be a real shame not to try those, especially if you’re after some special options.

Once you start researching resins, the range of options and variety of information can quickly become overwhelming. Numbers on spec sheets aren’t always enough, so in making our selection of the best options, we’re also taking into consideration our own experience and makers’ reviews.

The main types of resin include standard, water-washable, tough, draft, flexible, and high-resolution 8K. We’ll go over the aspects you should be aware of for each, as well as our top picks of brands.

It’s important to keep in mind that there are multiple resin 3D printing technologies available, such as LCDDLP, and SLA, and not every resin works optimally with each of these. In order to avoid confusion, we’ve first listed the products that are specifically compatible with LCD and DLP printers, and at the end, we’ve also grouped together proprietary SLA resins.

With that in mind, let’s go ahead and explore the world of 3D printing resin. Note that some brands sell resin by weight and others by volume, so for comparison purposes, 1 kilogram of resin is approximately equal to 1 liter.

Standard

Think of standard resins as the starting point in the world of resins. They’re not tailored for a specific use case, instead they’re just your daily driver and the one you’ll pull off the shelf for prototypes. Standard resins are mostly used for visual models due to the fact that they lack specific features (mainly in strength or thermal resistance) to be suitable for functional applications.

Some manufacturers have introduced so-called eco resins, which have a noticeably less intense smell when compared to standard resins. These eco resins can also fall under the Standard category as they’re not targeted for a specific application and are mostly suitable for general use or model making.

Here are our top choices for standard and eco resins!

Flashforge is a 3D printer manufacturer that also produces resins. An interesting fact about Flashforge’s standard resin is that it copes with heat very well; in fact, it can handle vacuum forming, a process where a heated film of plastic is pneumatically pulled onto a 3D printed model, resulting in a plastic mold of that part.

Moreover, the level of detail it’s capable of producing is among the best we’ve seen so far from a standard resin. The strength of printed parts is also relatively high, and there’s a variety of colors available. Perhaps the only real downside is the rather intense smell, but it’s certainly not alone in that.

  • Colors: White, black, red, green, gray, transparent, mint green, ice blue

Anycubic is a close competitor of Flashforge’s, and their special eco resin is an attempt to make resins more eco-friendly and bearable to work with as far as smell is concerned – a commendable effort.

Obviously, Anycubic wouldn’t disclose the formula of its plant-based resin, but what we do know is that it has a low epoxy content, which contributes to the greatly reduced odor. However, still make sure to take proper precautions when handling and disposing of this resin. The fact that it’s called “plant-based” doesn’t take away the importance of personal safety and safe disposal of hazardous substances. Don’t throw it down the drain, but let any leftover resin cure, and then you can safely dispose of the cured block of hard plastic.

Anycubic’s eco offering is quite a versatile resin, but it doesn’t produce the highest level of detail. Otherwise, it’s definitely a recommendation for makers and the eco-conscious, although it should be noted that not all colors are available in all sizes.

  • Colors: White, black, transparent green, gray, pink, blue, yellow, clear
  • Sizes: 0.5 kg, 1 kg

Water-Washable

Water-washable resins enable you to rinse your 3D printed parts with tap water instead of alcohol, which is required by all other types of resin. As alcohol adds up to the overall cost of resin 3D printing, the water-washable options are a bit more budget-friendly as well as easier to use.

Due to a change in formula compared to standard resins, water-washable resins come with a few compromises. Firstly, water-washable resins produce more brittle parts than standard resins, which is especially noticeable with hollow prints.

While curing times don’t differ when compared to standard resins, the overall processing time might, as water-washable resins need more time to dry off before being cured. Curing with too much water left in a part can lead to even more brittleness.

Prints from water-washable will not have as great long-term stability compared to parts from standard resin. This is due to the fact that water-washable resins are eager to absorb moisture, which could weaken the parts over time.

However, if used in dry environments for the purpose of something like visual prototypes, water-washable resins are a valuable tool, as it saves you the hassle of dealing with alcohol in the printing process. And the smell can even be a little less intense than that of standard resins.

We can’t stress this enough, but please remember not to rinse parts made with water-washable resin in your sink. The residual resin is still hazardous and should not be washed down the drain. Instead, learn how to dispose of resin in a safe manner.

With all of the above in mind, let’s take a look at our choices for best water-washable resins.

Tough

Tough resins are the ultimate choice when it comes to creating functional parts. What makes them worthy of such applications is their tweaked formula, which includes additives that contribute to the structural strength of the polymer.

It’s usually possible to drill into the models printed with tough resin without a major risk of cracks occurring, which is practical for post-processing applications that incorporate threaded inserts. The tougher surface is also more suitable for sanding without damaging the part.

Considering tough resins are aimed toward the professional and industrial side of resin 3D printing, the price per volume is higher than it is for standard resins. Also worth noting is how tough resins tend to have a slightly more intense smell when compared to other resins due to their formulation.

With all the above in mind, let’s take a look at our top picks for tough 3D printing resins.

Draft

With the nature of resin 3D printing, the type of resin can have an effect on the overall print time. This is due to the fact that resins have different curing times, with shorter curing times saving a lot of time in the printing process. Draft resins are specifically optimized for fast printing.

The name “draft resin” was initially introduced by Formlabs, which we’ll get to later, while other manufacturers use different naming, such as “rapid resin”. These resins are formulated so that the curing process can take as little time per layer as possible. Thicker layers can also contribute to lowering the print time, so some draft resins are also designed to print larger layers successfully. This is very practical for applications such as product development where prototyping requires a number of design iterations until the shape is finalized.

In case you’re wondering about the smell of draft resins, it’s usually not as bad as that of tough resins; it’s quite similar to the moderate intensity of standard 3D printing resin.

Keep in mind that draft resins don’t just lack the strength of other resins, they lack the stability too. So they’re not suitable for model making as they will almost certainly deform over time. We’ve had draft resins completely deform after just one day, so stick to using them to confirm your models are correct before printing the definitive version in another material.

Before you take your prototyping workflow to the next level with draft resin, let’s take a look at our top choices.

Flexible

There has been a lot of development in flexible resins in the last few years, and flexible resin prints have even made their way into consumer products like running shoes, bike saddles, drinking bottles, and even basketballs as showcased recently by Carbon. These resins usually specify how hard they are and tend to be quite tough due to their, well, flexibility.

Flexible resins try their best to mimic rubber. Parts made with flexible resin need to be durable, with the ability to withstand force and return to their initial shape. An important measurement for flexible resins is their hardness, measured on the Shore scale. The majority of flexible resins are rated somewhere around 80A Shore hardness but there is some variety in the market. Think of 80A as that of a solid rubber midsole.

There are some resins rated lower down the Shore scale – these are trying to mimic materials such as silicone. They’re a bigger struggle to print, considering the unique properties, but tweaking the settings around what the manufacturers suggest should get you to success. Just remember that when designing parts for flexible resin, you should always print the parts in their intended shape.

In spite of the material’s flexibility, it’s not meant for objects to be reshaped after printing. If you’re looking to 3D print lots of colored models with flexible resins, you may be disappointed by the fact that most flexible resins are limited to neutral or basic colors.

What’s not so impressive is the smell of flexible resins, which is often compared to that of tough resins. Bearing all that in mind, let’s take a look at our top picks!

8K

As the resin 3D printing market moves forward at a fast pace, the resolutions of screens fitted to LCD 3D printers are rapidly increasing. The first 4K resin printers have been available for less than two years, and we’ve already moved onto the so-called 8K resolution (referring to the approximate number of pixels across the width of the screen).

The terms 4K and 8K sound impressive and serve as a great resource for marketing material, and the same is true for 8K resins. If you don’t have an 8K machine, the quality produced by these resins won’t necessarily be superior to that of any other. Instead, manufacturers who offer such resin have simply tweaked them to work optimally with 8K 3D printing hardware.

In the following paragraphs, we’ll present the two most popular 8K resins which come from Elegoo and Phrozen, who both produce dedicated 8K resin printers as well.

Elegoo has applied a similar principle to Phrozen when it comes to 8K resin. That is, they’ve developed it to best suit their own machines, but it’s still possible to use it on other printers.

However, the difference is that Elegoo also offers a water-washable version of its 8K resin, which is a nice option to have.

What’s noticeable about both versions of Elegoo’s 8K resin is the effect of its low viscosity. FEP films tend to last longer when used with low-viscosity resins, as prints don’t stick as hard and therefore don’t damage the surface when removed.

SLA

After going over different types of resins that are best suited for LCD and DLP printers, we’ll take a look at a few Formlabs options that may be what you’re looking for in terms of best compatibility with an SLA machine.

Formlabs is a well-known US-based manufacturer of industrial SLA 3D printers. Naturally, they’ve developed their own portfolio of resins, which turned out to be incredibly impressive.

Formlabs Tough 2000

In Formlabs’ family of tough and durable resins, their Tough 2000 resin is said to be the strongest offering. The Tough 2000 resin is comparable to ABS, meaning it’s strong and doesn’t break easily. These properties make this resin ideal for functional prototypes.

The only slightly negative side of this resin is that it causes significant wear to the resin tank. Therefore, it requires frequent tank exchanges, ideally every 2-3 months if you’re printing often, which is something to consider because of the related expense and hassle. It’s also reported to be incompatible with the tanks of the Form 2 and 3 V1.

Keep in mind that this resin has exclusively been designed for use on Formlabs’ printers, but it can be, in theory, used on other SLA machines. If you choose the latter, be prepared to tweak print settings and iterate over a few test prints until you get satisfactory results. It’s also important to know that the hardware, such as the tanks of other printers, might not be suited for this resin, so if you don’t have a Formlabs machine, you may have an increased cost when it comes to such consumables.

If it’s not strength but speed you’re after, Formlabs created this resin in response to the need to speed up the printing process in applications such as rapid prototyping.

Formlabs have gone ahead and re-formulated their resin to create one that allows for much shorter curing times, therefore significantly reducing the overall print time. With this tweaked formula, there are a few compromises, such as strength and detail, but for the purpose of prototype iterations, it’s nearly perfect.

Formlabs claims this resin can cure up to three times faster than its other resins, which is quite a significant figure. It’s also been designed for printing at larger layer heights, which helps reduce the overall print time.

While this resin was made specifically for Formlabs printers, it should still work with other printers, although it’s always best to check possible compatibility against the manufacturer’s guide. The cost is what sets it apart from hobbyist projects, as it’s designed for businesses.

When it comes to flexible resins, Formlabs offers two choices.

The Flexible 80A is a fairly stiff resin but soft to the touch. Models printed with this resin have the feel of very rigid, hard rubber, which is ideal for applications such as grips, handles, gaskets, and so on.

The Elastic 50A, on the other hand, is a soft, flexible resin, meaning that parts made with it resemble silicone. This resin has big potential in the area of wearables, such as shoe soles and masks.

As with any other Formlabs resin, the results are of a very high standard. In case you’re not a Formlabs printer user, keep in mind that this resin is officially intended for Formlabs printers, limiting compatibility with other machines, though you can always experiment on your own printer.
