What’s more, the glue features an anti-clog cap that prevents the glue from drying up. As a result, you can use it till its last drop, so kudos to Gorilla brand for getting that right!

What Could’ve Been Better?

Though there isn’t much to complain about this versatile formula, there’s a minor flaw you must know. While the glue works great, it has an unusual smell, which is why we recommend wearing a mask or working in a well-ventilated area. 

Pros
  • Quick-setting formula
  • Versatile applications
  • Easy to use
  • Doesn’t clog
Cons
  • Strong smell

Why Did We Like It?

More than anything, we were impressed by the sheer versatility of this glue. Not only does it come handy to glue PLA pieces, but it can be used for bonding ceramics, metals, china, fingernails, wood, jewelry, and many more. 

Much like the previous pick, this fast-drying glue sets within 10 to 30 seconds. Crafters will appreciate the design of the bottle as it features a precision applicator that eliminates drips, making it perfect for vertical applications. 

What’s particularly interesting is that this glue doesn’t leave any residue after drying as it dries clear and can be painted and sanded. 

Better yet, the package contains 12 tubes of 12-grams each, so they’ll last you for a variety of projects. Also, we loved the packaging of this glue as it comes in a sturdy plastic box for safe storage. Oh, and did we mention that the brand offers excellent value for money?

What Could’ve Been Better?

While this glue is one of the best glue for PLA and other materials, it is messy to use and can stick to the skin. That’s why we suggest you wear a pair of latex gloves while using this glue on your PLA projects. Other than this minor flaw, this kit is a steal! 

Pros
  • Usable on a variety of surfaces
  • Quick-drying formula
  • Can be painted and sanded
  • Excellent value for money

Why Did We Like It?

Finding a glue for PLA that withstands extreme temperatures is quite difficult. However, this super glue by Loctite is right up the street as it forms weather-resistant bonds. Hence, you can use it to fill cracks on PLA containers, saucers, lids, and other materials. 

What impresses us the most is the non-drip gel formula that makes it perfect for bonding vertical PLA surface. Moreover, it forms solid and durable bonds to resist vibration, impact, and shock, so you can use the object daily without worrying about the bonds. 

The patented control applicator is a thoughtful inclusion by the brand as it lets users dispense glue as needed. This makes it a mess-free adhesive and adds to the users’ convenience. 

Better yet, it has a self-piercing, screw-on cap that prevents the air from sneaking into the glue, ensuring maximum reusability. Furthermore, the glue is available in three packs for customers to choose from. 

What Could’ve Been Better?

Although the bonds are highly durable and weather-resistant, we wouldn’t recommend this glue for immediate repairs because of its curing time. Even though it sets within a minute, it takes about 24 hours to cure. Hence, it might not be an ideal option for those looking for a quick-fix glue. 

Pros
  • Forms a transparent layer on drying
  • Offers precision and control
  • Mess-free application
  • Ideal for vertical surfaces
Cons
  • Long curing time

What Could’ve Been Better?

Even though this super glue comes in handy for a variety of DIY projects, it emits a strong smell, bordering on unbearable. Hence, we suggest you use a mask, glasses, and wear gloves while working with this glue. Also, make sure you work in a well-ventilated space to avoid inhaling the fumes. 

Pros
  • Forms strong bonds
  • Usable on multiple surfaces

What Could’ve Been Better?

If you’re looking for a dependable option for your PLA models, this acrylic plastic cement is the best bet. However, it doesn’t dry clear and leaves a milky white look after it dries. Thus, it might not be an ideal choice for those looking for adhesives that dry clear.

Pros
  • Versatile
  • Forms durable bonds
  • Easy to use
  • Ample working time
Cons
  • Doesn’t dry clear

6. Starbond

Moreover, it comes with extra attachments for fuss-free applications. The package includes a pair of applicator caps, a clog-free stopper, and a bag of micro tips. The clog-stopper will come in handy for unclogging the nozzle, while the micro tips will let you fill tiny holes. 

Though the two-ounce bottle will be sufficient for your two or three DIY projects, it has a shelf life of 30 months. Also, if the glue doesn’t last, you’ll receive a 100% refund.

What Could’ve Been Better?

When it comes to bonding PLA models and filling challenging nooks and crevices, this glue does a decent job. However, this glue forms incredibly tough bonds, so it can bond skin. That’s why we suggest using a pair of latex gloves when working with this glue. 

Pros
  • Easy applications
  • Comes with a clog-free stopper
  • 30-month shelf life
  • Incredibly tough bonds
Cons

Glue for pla buying guide 

Glue For PLA Buying Guide 

While knowing the six best glue for PLA certainly helps to a great extent, choosing the right one for your needs is still a daunting task. That’s because there are numerous factors that you need to pay attention to while choosing the right glue for PLA for your projects. 

On that note, we’ve discussed some important factors you must keep in mind when shopping for glue for PLA. 

1. Surface 

The first thing you must consider before buying glue for PLA is the surface area you intend to use it on. For instance, if you have to bond sanded PLA, it will be useless to go for glue formulated for unsanded surfaces. 

Moreover, if you’re looking to bond porous surfaces, we suggest going for glues that form durable bonds and are weather-resistant. So, before deciding which glue to go for, consider the surface you have to bond. 

2. Flexibility

The next thing to consider is the flexibility of the glue for PLA you’re opting for, as glues differ from one another in terms of flexibility. While most glues assume a rigid position after the curing process, some glues offer slight room for movement. 

Whether you must go for a glue that offers flexibility or stays rigid depends upon your needs. Hence, we suggest you consider the project you have to work on and decide accordingly. 

3. Drying Time

The drying time of each glue varies from the other, and that’s why you must consider this factor when selecting glue for your 3d PLA projects. Some may dry within a few hours, while others may take a day or two. 

Moreover, if you have to complete your project quickly, glues with a short drying time will be the best bet. Though you can go for glues that come with a longer drying time, you’ll have to wait for some time before using the creations. 

4. Appearance

If you’ve been into DIYs for quite some time, you must know that not all glues dry clear. And that’s why you cannot just pick any glue you want. Moreover, it isn’t challenging to get glue for PLA that dries clear since most brands manufacture clear and transparent glues. 

However, most glues can be sanded and painted, so you can paint them even if they leave a milky white color. 

Best glue for pla

Verdict

Though challenging, bonding PLA surfaces isn’t impossible. If you’re thinking of using PLA filament, epoxy resin, hot glue stick, wood glue for bonding PLA, we will urge you to try the glue for PLA specifically formulated for bonding PLA. 

With that, we’ve reached the end of our guide. Hopefully, you’ll be able to choose the right one for your projects. But, before we bring the curtains down, let us tell you our favorites from the list. 

The Gorilla Glue is our top recommendation because of its versatile and impact-tough formula. However, if you’re looking for glue for PLA that can be painted and sanded, the Super Glue is the best bet. 

Be sure to let us know which glue you ended up choosing for your DIY projects. Till then, happy crafting!
