What is the best PLA glue for 3D printing?

The PLA (polylactic acid) is today one of the most popular filaments in the world of 3D printing. Easy to print, precise and available in a multitude of colors, it is used by individuals and makers as well as by modelers and professionals.

But one question comes up regularly after printing:

what is the best PLA glue for joining two 3D printed parts?

When a model is too large to be printed in one go, when a figurine has several elements or when a part breaks, it is necessary to be able to produce a precise and resistant assembly without damaging the print.

This is exactly where the choice of glue becomes essential.

At Super Glue Colle21, we have been developing for more than 13 years cyanoacrylate glues and professional adhesives, with different viscosities to meet the specific needs of 3D printing.

Thanks to a range of more than 140 products and to an excellent value for money, Colle21 offers solutions adapted to PLA, but also to many other materials and applications.

What is the PLA ?

PLA is an extremely popular thermoplastic in FDM 3D printing.

It is particularly appreciated for:

its ease of printing;
its good dimensional accuracy;
its rigidity;
its excellent quality of finish;
its wide choice of colors;
its low tendency to warping compared to certain other filaments.

Today we find PLA printing in many areas:

figurines;
cosplay;
prototypes;
models;
model making;
decoration;
technical parts;
accessories ;
personalized objects;
creative hobbies.

But 3D printing often requires dividing a project into several elements.

It then becomes essential to have a good glue for PLA.

Why is cyanoacrylate interesting for glue the PLA ?

For many assemblies of parts printed in PLA, the cyanoacrylate glue, often called Super Glue, is a particularly practical solution.

It has several advantages:

✔ rapid setting;

✔ precise application;

✔ small quantity required;

✔ excellent ease of use;

✔ different viscosities available;

✔ suitable for both small and large rooms depending on the formulation chosen.

It is particularly interesting for figurines, prototypes, models and objects made up of several prints.

Best PLA glue: which viscosity to choose?

This is a point often overlooked.

Search only for « best PLA glue » is not enough: you must also choose the viscosity corresponding to the work to be carried out.

This is precisely one of the advantages of the range Super Glue Colle21.

We offer several formulations allowing you to adapt the glue to the project rather than systematically using the same product.

Super Glue Colle21 FAST: for very precise assemblies

The Colle21 FAST has a low viscosity.

It is particularly interesting when two printed pieces fit perfectly.

Its fluidity allows it to penetrate very small spaces by capillary action.

It is particularly suitable for:

small PLA parts;
figurines;
miniatures;
printed details;
perfectly adjusted assemblies.

For extremely precise assembly, a fluid glue can offer a real advantage.

Super Glue Colle21 Classic: the versatile solution

For general use, the Super Glue Colle21 Classic is an excellent solution.

It allows you to perform as well:

repairs;
assemblies;
figurine montages;
prototypes;
3D printed accessories.

It is a versatile solution for users who regularly work with PLA.

Super Glue Colle21 DENSE: control the glue and avoid runs

On some 3D prints, glue that is too liquid may move along the print lines.

For these applications, Super Glue Colle21 DENSE provides better control.

Its higher viscosity allows you to deposit precisely the necessary quantity.

It is particularly interesting for:

large figurines;
busts;
vertical pieces;
assemblies with slight play;
visible areas.

The glue stays more where it is placed, which makes work easier.

Super Glue Colle21 GEL: for maximum control

When the assembly has a larger space or the part is difficult to position, a GEL formulation can be particularly practical.

The Super Glue Colle21 FREEZE strongly limits dripping and allows precise control of the application.

It can be used for:

large prints;
vertical pieces;
localized repairs;
decorative objects;
projects requiring highly controlled application.

Super Glue Colle21 FLEX: when the project requires more flexibility

A part printed in PLA can sometimes be subject to vibrations or small mechanical stresses.

In certain situations, a more flexible formulation may be advantageous.

Super Glue Colle21 FLEX thus completes our range and allows us to further adapt the product to the specific constraints of the project.

That's the whole philosophy Colle21 :

not offering a single universal glue for everything, but different solutions for different needs.

How to glue two pieces PLA correctly?

Even the best glue will perform poorly if the surfaces are poorly prepared.

Here is a simple method.

1. Check the fit

Before applying the glue, assemble the parts dry.

This step allows you to verify that the two elements match perfectly.

2. Clean surfaces

Eliminate:

dust;
fat ;
sanding residue;
dirt.

Surfaces must be clean and dry.

3. Lightly sand if necessary

On some prints, light sanding of the joining area can improve contact between the two surfaces.

4. Apply little glue

A very common mistake is to use too much cyanoacrylate.

More glue does not necessarily mean more strength.

Only deposit the amount needed.

5. Position the pieces

Align the two elements correctly and hold them during the initial setting.

6. Respect polymerization

Even when an adhesive appears to have set quickly, it is preferable to wait for complete polymerization before subjecting the assembly to significant stress.

Paste a figurine printed in PLA

One of the most common applications is figurines.

A figurine can be printed in several parts:

head;
body ;
arm ;
legs ;
weapons;
accessories ;
base.

For this work, precision is essential.

A Colle21 FAST can be suitable for perfectly fitted assemblies, while a DENSE or GEL provides more control when there is a small space between elements.

Paste large 3D prints

3D printers have a limited printing surface.

To manufacture a large object, it is therefore often necessary to divide the digital model into several parts.

This is particularly the case for:

cosplay helmets;
decorations;
statues;
prototypes;
large models;
accessories.

In this case, the bonding surface becomes larger.

A wording DENSE or GEL can make application easier and prevent glue from leaking before assembly.

Repairing a Broken PLA Print

A 3D print can break after being dropped or mishandled.

Before throwing it away, examine the breakage.

If the two pieces can be repositioned correctly, a repair is often possible.

Clean the surfaces, carry out a blank assembly and choose the appropriate viscosity.

This approach helps extend the lifespan of many 3D printed creations.

PLA, ABS, PETG, resin: is one glue enough?

3D printing today uses many materials.

Among the most popular:

PLA;
ABS;
PETG;
TPU;
UV resins.

The behavior of each material is different.

This is why Super Glue Colle21 offers a wide range of glues, primers, activators and complementary products, in order to adapt the solution to the support and the application.

For plastics that are particularly difficult to bond, it is always recommended to check compatibility and carry out a preliminary test.

FAQ – Best PLA Glue

What is the best glue for PLA?

For many PLA assemblies, a quality cyanoacrylate glue provides a quick and precise solution. Viscosity should be chosen based on the fit and size of the parts.

What Super Glue Colle21 use on PLA?

For very precise assembly, FAST is particularly interesting. For more control, DENSE or GEL may be privileged.

Can you repair a broken PLA 3D print?

Yes, when the pieces can be correctly repositioned and the surfaces are clean and compatible with the chosen adhesive.

What glue should I use for a PLA figurine?

A cyanoacrylate allows the different parts to be quickly assembled. FAST is suitable for very tight joints, while DENSE or GEL facilitate joints requiring more control.

Should you sand PLA before gluing it?

This is not systematically necessary. Light sanding can nevertheless improve the contact surface on certain parts.

Can you use a lot of glue to increase strength?

No. On the contrary, an excess of cyanoacrylate can complicate assembly. A fine and controlled application is generally preferable.
