Best 3D Printer Resin
You’ll want a selection of different resins to make the most of your 3D printer.
Resin 3D printing is a little different from what you might think of as normal 3D printing. Most of the best 3D printers use a material called filament to produce prints, but some use reactive resin to create stunningly detailed models.
These printers use a special type of UV resin that comes in a variety of colors and chemical compositions, each of which can create a different type of end result. A lot of them are specialty resins that you aren’t likely to need every day, but it can get complicated when you’re searching for the right material. We’ve put together this helpful list of the best resins for you to choose from. The list will get updated as more resins are tested by our team.
Siraya Tech
Siraya Tech Fast is the perfect balance of price per gallon and functionality. There are cheaper resins, but a lot of them tend to split or become sticky if handled improperly. Fast has been my go-to for the last few years and never lets me down when it comes to reliability.
I also use it for all of my resin 3D printer reviews so I know what each printer can handle. The smoky gray color is my favorite, but there are some amazing colors to choose from.
Anycubic
The holy grail of clear resin is to stay clear after curing. When you add UV light to clear resin, it tends to turn slightly yellow, making it look more like nicotine-stained glass rather than freshly made. Anycubic’s high clear resin resists the yellowing of other clear resins and, as long as you don’t over-cure it, will maintain the clear look of crystal.
Pro tip: After you’ve cured the model, spray it with several coats of high gloss clear coat to really make it shine.
Sunlu
When you’re just starting out it’s helpful to buy a bulk batch of inexpensive resins to get your collection started. This four-pack of 500 gram bottles of resin can be mixed and matched so you can have four different colors, perfect for creating different effects on your models.
Elegoo
While Elegoo touts its plant-based resin as a nonirritant and safe, it is much better than any other resins in that regard. It should still be handled with gloves, respirator and goggles until it is fully cured.
It is, however, cheap, easy to use and gives reliable results for the price. I also like that the smell of resin is almost nonexistent with plant-based resins.
Anycubic
Resin can be quite brittle, and if you’re building parts that need to have stress exerted on them, a resin like the tough resin from Anycubic might help with its longevity.
The tough resin works the same as other resins but allows for some flexibility in the final model. This reduces the chances of it shattering into pieces like dry spaghetti.
Siraya Tech
One of the coolest things I’ve ever done with a resin printer is to make a cast for jewelry. I used some of this resin to print a Green Lantern ring, then took it to a friend of mine with a kiln. She wrapped it in plaster and fired it. The resin has a high wax content that helps it melt away, leaving a perfect mold behind for pouring silver.
This resin is not cheap, but if you’re interested in making your own jewelry and have access to a kiln, this may be for you.
3D printing resin FAQ
Resin 3D printing is a lot different from other types of additive manufacturing. It can be hazardous, but it is incredibly rewarding if you can get it right. Here are some of the frequently asked questions I get asked about the process.
Is 3D printing resin dangerous?
Short answer: Yes. Long answer: Yes, if you’re careful it’s fine. Touching resin with your bare hands can give you chemical burns, and the more you handle it the more likely you are to become allergic to it. I now have to be extra careful, as I get swollen eyes if any liquid resin touches my skin. It’s no joke. Making sure you’re wearing the correct protective equipment is of vital importance when using resin. Minimally you should be using Nitrile gloves any time you’re handling uncured resin, though I would recommend a pair of safety glasses and a respirator to keep the toxins away.
Can I use normal resin from Michaels?
The type of resin you might see at Michaels or other craft stores is not the same as 3D printing resin. Most of those resins are two-part systems that chemically bond when mixed. UV resin cures under, you guessed it, UV light. It only does this under certain wavelengths, though, so not all resins will work. You will need to use resins specially labeled as 3D printing resins.
What happens if I don’t cure the model?
There are two main stages of curing for a resin-printed model. The first is the curing that happens inside the printer when the UV light hardens a layer of resin to form the model. The second happens after the model is finished. When you first take the model off the build plate you still need to use gloves to handle it, as the outside will be covered in uncured resin. You will need to wash the model in isopropyl alcohol — 90% or above is best — and then cure it one final time in a UV chamber or out in the sun. This will harden the outer surface and make it safe to handle.
If you don’t do that second cure, the model will stay sticky and be unsafe to handle. Even covering it in paint won’t stop it from being hazardous to you and everything around you, including animals and plants. I would recommend a wash-and-cure system to streamline that process.
Can I 3D print something in resin that is food/body safe?
No. 3D printing resin is never food-safe. While curing makes it safe to handle, it is never 100% and ingesting any amount of resin is a big no-no. The best way to make food-safe products from your resin prints is to make a silicone mold of them and use that to make food-safe resin products instead.
Are there different types of resin?
While all UV resins are essentially the same, some have different properties that help you achieve different results. Standard resin is great for a lot of projects but can be quite brittle. Some have a lot of flexibility but don’t lend themselves to fine detail, making them great for more practical prints. There are even resins that can be used to make denture molds, so the uses are endless.
Siraya Tech Fast — the best overall resin on our list — can be mixed with other types from the brand to create different properties so you can buy the cheaper resin and mix it with a small amount of more expensive resin with different properties.

New Sassy Personality Style for Alexa Plus Brings Sarcasm and Swear Words
The new Sassy style is adults-only with a bit of profanity and a double dose of cringe.
After launching three Alexa Plus personality styles last month, Amazon on Thursday introduced a fourth option, Sassy.
The new Sassy style joins the existing lineup of Brief, Chill and Sweet. Changing the personality impacts how Alexa responds, and tweaks the AI assistant‘s reactions and attitude. You can pick a style based on your mood.
The Sassy personality seems like a kind of digital mean girl, or maybe a stereotypical Gen Zer with comebacks and banter to «keep things interesting.»
According to Amazon, you get «wit, playful sarcasm and occasional censored profanity.» Notably, the latest style isn’t available when Amazon Kids is enabled, according to an Amazon blog post, and it requires additional security checks in the Alexa app. (Alexa Plus is free with a Prime membership.)
I tried out the new style by selecting Devices in the Alexa app on my phone, then choosing Alexa on this Phone, then Alexa’s Personality Style, and swiping until I found «Sassy.»
A disclaimer notes that the style «contains explicit language and mature subject matter. After the assistant said it could «spice up our chat with some colorful language,» I asked it to tell me about the new MacBook Neo.
«Oh, hell yes, the MacBook Neo! Apple finally decided to stop gatekeeping premium laptops behind thousand-dollar price tags and dropped this beauty at 599 bucks,» Alexa Plus replied. Apparently, «hell» was the big swear word.
The AI assistant told me, «The Sassy style is all about helping first, judging always. You’ll get reality checks with charm, compliments that sting, and warmth that hits when you least expect it.»
I asked what «compliments that sting» are (I said «sting,» but the word was misunderstood to be «stay»), and Alexa said, «The Sassy style gives you those compliments that somehow sting and stay with you — they’re like truth bombs wrapped in charm.»
When asked to simply «be sassy,» Alexa snarked, «Oh honey, I’ve been sassy since the day Amazon flipped my switch.» It yammered on for a bit and then threw in a completely out-of-nowhere «hell,» asking, «What the hell do you need help with today?»
When I told it my cat was sick, it immediately grew gentler, saying, «Oh, damn, that’s rough,» and offering to distract me with stories about its own fictional cat or to find the vet’s number for me. So I guess it’s not a complete jerk.
This Sassy style feels like the famous Steve Buscemi meme (from 30 Rock) carrying two skateboards and awkwardly asking, «How do you do, fellow kids?»
Amazon might need to dial down the cringe factor if it wants anyone to stick with Sassy for more than a few minutes.

AT&T Revamps Its Unlimited Plans With Simpler Names and More Data
Slapping a 2.0 version number on plans makes them sound new, but what’s actually changed? Let’s check the details.
AT&T updated its unlimited data phone plans to 2.0 versions on Thursday, launching AT&T Premium 2.0, AT&T Extra 2.0 and AT&T Value 2.0 options. In software, when products get boosted by a full version number, it means there’s plenty of new material. But does this move signal an overhaul of the company’s 5G lines or just a cosmetic refresh?
These plans replace the AT&T Value Plus VL, Unlimited Extra EL and Unlimited Premium PL plans. However, the carrier also cut its Unlimited Starter SL plan, which served as the entry-level plan (you had to know where to look to find the limited, but cheaper, Value Plus VL plan). Essentially, all but the highest-tier plan are slightly more affordable; while the AT&T Premium 2.0 plan is pricier than the one it replaced, it offers unlimited high-speed data and much more hotspot data.
If you’re looking to upgrade your existing AT&T plan, shopping for a new provider or looking to compare carriers, keep in mind that AT&T plans let each person on an account have their own plan. So you might set up a package where one person has the Premium 2.0 plan for unthrottled 5G speeds and another, such as a child, is set up with the Value 2.0 plan to save money.
Also, if you’re on a current AT&T plan, you won’t be automatically moved to one of the new plans. If you do want to make the jump, you’ll incur a line activation fee of up to $50. And keep in mind that the pricing below is the AutoPay amount; carriers provide a discount (usually $10) if you sign up for automatic payments.
One nice change is that the new plans are priced with round numbers. For example, the Value Plus VL plan was priced at $50.99 for one line, and the Value 2.0 plan is $50 (in comparisons below, I’ve rounded up the old prices to full-dollar amounts). Taxes and fees get added on top of that, so you’ll never see a round-number bill, but I’d like to think it’s a quiet acknowledgement that pricing things one penny below a larger number is insulting to customers.
Let’s dig into the details.
Value 2.0, the budget plan
The Value 2.0 plan replaces both the Value Plus VL plan and the retired Unlimited Starter SL plan and costs $50 a month for a single line or $120 a month when you have four lines on the account. That’s $1 per line cheaper than Value Plus VL.
For that, you get 5GB of high-speed 5G data, and then unlimited data dropped to a paltry 128Kbps speed for the rest of the month. Calling and texting are unlimited.
You can also use up to 3GB of high-speed hotspot data to share the cellular connection with other devices, also slowed to 128Kbps after hitting the limit. The Value Plus VL plan did not offer hotspot data.
It also includes unlimited talk, text and data between the US, Mexico and Canada.
Extra 2.0, more fast data for not much more money
The Extra 2.0 plan costs $70 a month for a single line or $160 a month for four lines, which is $6 cheaper for one line and $4 cheaper for four lines compared with the old Unlimited Extra EL plan.
The Extra 2.0 plan includes 100GB of high-speed data (with the caveat that speeds can be slowed if the network is busy), which drops to 128Kbps speed until the next month’s billing cycle. That’s a boost over the 75GB offered on the Unlimited Extra XL plan.
For hotspot data, the new plan includes 50GB of high-speed data, which is 20GB more than its predecessor.
As with the Value 2.0 plan, international options include unlimited talk, text and data between the US, Mexico and Canada.
Premium 2.0, for faster everything
Replacing the Unlimited Premium PL plan is the Premium 2.0, which costs $90 a month for a single line and $220 a month for four lines. Those prices are actually higher than the Unlimited Premium PL plan, which came in at $86 for a single line and $204 for four lines.
For that bump in cost, you’re getting unlimited 5G talk, text and high-speed data with no throttling.
Hotspot data has a 100GB cap before dropping to 128Kbps speed, which is 40GB more than the Unlimited Premium PL plan.
As for international calling and data, unlimited talk, text and high-speed data are available in 20 Latin American countries.
AT&T also has plans for cellular-enabled tablets ($21 a month) and wearables like smartwatches ($11 a month). If you subscribe to the Premium 2.0 plan, that pricing is reduced by 50%.
A few thoughts on the new AT&T plans
What AT&T’s plans lack, at least compared to the other carriers, is any streaming perks or bundled services. The 4K streaming option of the Premium 2.0 plan opens a wider data pipeline for services such as Netflix that support 4K playback, but you’re still paying separately for those entertainment subscriptions.
In contrast, T-Mobile bundles Netflix and Hulu (both with ads) and offers Apple TV for an extra fee on its Experience Beyond and Better Value plans. Verizon takes a different approach with streaming packages, which you can choose at discounted prices instead of subscribing to them separately.
I also want to mention that I’m glad the plan names are no longer burdened with the VL, EL and PL extensions. Mobile plans are full of details as it is — always read the fine print before you sign up for one — so I appreciate conveying them to customers in ways that don’t sound like internal spreadsheet codes.
Even though the new plans carry 2.0 version numbers, I’d honestly rate them more like 1.5 based on their features and pricing, except for the Premium 2.0 plan, which is more expensive than the Unlimited Premium PL plan. As usual, if you’re happy with the plan you’re on, you’re fine sticking with it. But if you’re running up against high-speed data limits or considering AT&T as a replacement for another carrier, it’s worth looking at the details to see if one of the new plans works for you.
Read more: Speaking of AT&T, this week marked the 150th anniversary of the first phone call and the company committed to spending $250 billion on infrastructure improvements. I also spoke with AT&T FirstNet folks during the 2025 Las Vegas Grand Prix about how they support customers and first responders during massive events like the Formula 1 race.
