Once you delve into the world of 3D printing, you will discover that not all of your printing projects will be perfectly finished straight out of the printer. Sometimes you will need to join several parts together, and that is exactly when gluing becomes an invaluable skill. But how do you properly glue 3D prints? Which methods are best for different materials? In this article, we will try to answer these questions.

How to Start Gluing 3D Prints: A Beginner’s Guide

Getting started with gluing 3D prints does not have to be as complicated as it may seem. The first and most important step is choosing the right adhesive. There are many adhesives designed for the different types of plastics commonly used in 3D printing, so it is important to choose the right one. For ABS plastic, acetone is the best choice, while for PLA and PETG, epoxy adhesive or superglue is suitable.

The next step is surface preparation. The surfaces must be clean, dry, and smooth for optimal adhesion. If the surface is uneven or greasy, the adhesive may not hold properly. It can also be useful to use an abrasive material, such as sandpaper, to create a rougher surface that the adhesive can grip more effectively.

Finally, it is important to let the adhesive dry properly. The drying time may vary depending on the type of adhesive and the material you are gluing, so it is important to follow the manufacturer’s instructions.

The Best Gluing Methods for Different 3D Printing Materials

As already mentioned, different materials require different types of adhesives. ABS plastic is particularly suitable for gluing with acetone because acetone dissolves ABS and creates strong bonds. Simply apply acetone to both surfaces being joined, press them together, and let them dry.

PLA and PETG are generally more resistant to chemical solvents, so strong adhesives such as epoxy adhesive or superglue are suitable for gluing these materials. These adhesives create strong bonds and are versatile enough to be used on a variety of materials.

Another option is to use a special adhesive for 3D printing. These adhesives are designed to adhere well to materials used in 3D printing and provide strong, durable bonds. Although they are generally more expensive than ordinary adhesives, they may be worth it if you need to join complicated or large parts.

Gluing 3D prints can be an essential part of completing your project. Although it may seem complicated, once you master the basic techniques and choose the right adhesive for your material, you will find that gluing can be easy and effective. Whether you are working with ABS, PLA, PETG, or any other material, there is always a suitable gluing method to help you achieve a perfect result.
