BuildTak vs PEI: Which Build Plate Should Choose?

BuildTak vs PEI

It feels great to print your own designed 3D models, isn’t it? Whether it is your favorite action figure, unique jewelry pieces, or replacement gears for tools and machines, a 3D printer is capable of printing all that while keeping you away from spending on those items.

And in order to get flawless, high-quality printed models, you should consider not only the printer model but also its build plate.

Yes, that’s right. The build plate of a 3D printer is a crucial component because it provides a flat base to your 3D printed models. Plus, it holds the object into place while it is being printed.

There are plenty of build surfaces available in the market, with the most common ones being PEI and BuildTak. Both build surfaces come with their own advantages and disadvantages and so it can be difficult to choose the one you need.

But don’t worry, because once to you get to know deeply about them in this PEI VS BuildTak article, you can make an informed decision about which one to choose.

What Is PEI?


PEI, also known as Polyetherimide, is a thermoplastic that retains its high strength and rigidity at higher temperatures, resists chemicals, retards flames, offers dimensional stability, and possesses excellent electrical properties.

As for 3D printing, PEI is a build surface that doesn’t require any maintenance but is used to work with almost all types of 3D printing filaments.

You can use PEI on a heated or unheated print bed without using adhesives, rafts, or brims. That’s because most PEI surfaces already come with a laminated adhesive backing that you can peel off and stick to the print bed.

PEI is great for use in the long run because you can always reuse it whenever you’re done printing a 3D model. All you need to do is clean the surface with isopropyl alcohol in between printing models. This prevents any residue from a printed model from sticking to others.

Advantages Of PEI

1. Easy To Install

First off, PEI is easy to install. Most PEI build surfaces come with an adhesive backing which you remove and apply onto the print bed. There’s no need to use additional adhesives or even a brim or a raft.

You can choose such PEI sheets if you want the installation process to be hassle-free. Beginners who often struggle with adhesion can also greatly benefit from using it.

It is also important to note that some PEI sheets don’t have an adhesive backing, and so they require you to use glue or tape.

2. Cost-Effective

PEI sheets are affordable, which makes them easily accessible for beginners as well as professionals. Despite being affordable, PEI sheets let you print 3D models for more hours and ensure high-quality results.

While you can purchase a PEI sheet for your existing 3D printer, some 3D printers already come with a PEI sheet to save the cost of purchasing one separately.

3. Provides Good Thermal Conductivity

PEI has the advantage of withstanding high temperatures of up to 400 degrees Celsius. This allows you to print 3D models at high temperatures without worrying about the build surface getting damaged due to overheating. Because of its high heat resistance, PEI is a durable material.

4. Provides A Smooth Finish

The first layer of a 3D printed model determines how well the rest of the layers will follow. Since PEI doesn’t cause any interruptions in the first layer, the resulting 3D printed model will have a smooth surface.

5. Requires Less Maintenance

It is possible to reuse PEI sheets once you have already used them for printing 3D models. After each use, it is recommended to clean the build surface with isopropyl alcohol, and it will look good as new!

Disadvantages Of PEI

1. Soft Material That Is Prone To Damage

Although being able to withstand high temperatures, PEI is prone to damage. That’s because the material is soft, and if the print bed is not leveled properly prior to printing, it can lead to permanent damage on the PEI sheet.

2. The Adhesive Can Become Stuck To The Print Bed

PEI sheets that don’t come with adhesive backing need to be applied to the print bed using tape or glue. While the process can be time-consuming, the tackiness of the adhesive can further consume time in removing the adhesive from the print bed. It might also lead to damage to the print bed.

3. Improper Bed Leveling Can Damage Prints

Another drawback of PEI is that, if you align the print bed and the nozzle improperly, it can lead to damage to your 3D prints. Not only that but also calibrating the components to perfection can be time-consuming. Unless you do it properly, you might have to let the filament and the PEI sheet go to waste.

What Is BuildTak?


BuildTak is a popular 3D printing build surface used by many 3D printing enthusiasts. It is made of plastic, and it can withstand high temperatures of up to 125 degrees Celsius.

BuildTak is versatile as it works with all types of filaments, including PLA, ABS, PETG, TPE, HIPS, and WoodFill. So, it eliminates the hassle of swapping build surfaces for printing with different filaments.

Plus, it comes with an adhesive backing that makes it easier to apply on the print bed. There’s no need to use rafts or brims for adding support to the 3D printed model.

Advantages Of BuildTak

1. Easy To Install

BuildTak comes with an adhesive backing that you can peel off and apply to the print bed directly. Since it doesn’t require additional adhesives, such as glue or tape, you can save your time going through the additional steps.

2. Compatible With Different Filaments

BuildTak is versatile because it supports a range of filaments, including PLA, ABS, PETG, TPE, HIPS, and WoodFill. It saves you from the hassle of swapping build surfaces in between printing with different filaments and provides a quicker way for printing.

3. Easy To Clean And Remove

Unlike most cost-effective DIY build surfaces, BuildTak comes with an adhesive that is easy to apply and remove. The adhesive won’t get stuck to the print bed and consume your time in cleaning it up. This makes it easy for you to print 3D models in a row.

4. Provides A Smooth Finish

During the creation of a first layer, the filament evenly sticks to the printing surface. That means the rest of the layers will also follow well and the resulting object will have a smooth finish. The object will not warp after the printing process is done.

Disadvantages Of BuildTak

1. Expensive

Since BuildTak works with different filaments and also can be re-used, it costs a bit more than other build surfaces. Beginners might not find BuildTak a good choice when they’re learning how to print 3D models because any damage to the build surface can lead to a waste of money.
