2024 TPE Filament For 3D Printing – The Ultimate Buyer’s Guide

With time, the number of possibilities in terms of diverse filament choices is surging within the 3D Printing industry. And, one such example is TPE.

Using TPE Filament you can manufacture parts possessing non-slip characteristics and flexibility. The most common example of TPE application is the flexible phone cases.

The other application in which you can find TPE is, dampeners, medical prosthetics, and industrial applications wherein you need functional prototypes to counter loads. Apart from making objects extremely flexible, TPE also makes them intensely durable.

TPE stands for Thermoplastic Elastomers that do not specifically refer to one material, but a varied range of elastic thermoplastics. While buying TPE filament you’ll often observe it being associated with TPU.

Although there are many differences between these two and in the way they are used to make parts, the best way to differentiate is by noting their technical hardness ratings.

Any material of hardness 90A or below is termed to be TPEs even if the base material of the resulting elastomer is TPU.

So, let’s discuss the many properties of TPE that make it unique and one of its kind. We will learn about the various facts related to the printing and storage conditions that you need to take care of when working with TPE.

Remember, TPE is a flexible filament. Therefore, you need to take more precautions while 3D printing it than you used to while using ABS or PLA or any other choice.

You will also face some challenges, but if dealt with patience and correct settings, the resulting objects will turn out to inherit rubber-like qualities. And that’s something only achievable with this material.

So, let’s start diving into this special material TPE by looking at its printer settings and storage conditions.

Printer Settings

What Are The Printer Settings

Buckling or squeezing through gaps in the filament pathway are two of the most general problems while 3D printing TPE. So, make sure your path does not have any gaps or obstacles.

You are recommended to use a direct drive extruder, not a Bowden one. The other part you need to be keen on is retraction.

As TPE is stretchable and can be compressed, retraction is usually disabled while 3D printing the material. The other issue is with adhesion.

Generally, while printing with TPE advice is to use a painter’s tape, glue stick, or hairspray.

While TPE 3D printing, ensure the nozzle temperature ranges between 190 to 250 degrees Celsius as per the brand you use.

Similarly, keep the bed temperatures ranging between 0 to 70 degrees Celsius as per the brand of TPE filament you are using.

Experts advise the print speed range to be around 5 to 50 millimeters per second.

Storage Conditions

TPE filaments are hygroscopic, meaning that they absorb moisture from the air. So, if you keep storing the filament in an open atmosphere, they would not be able to produce good quality prints.

Instead, the material should be stored in a low-humidity environment like an air-tight container or bag with desiccant packs.

Having gone through the printer settings and storage conditions it’s time now to go through different brands of TPE filaments that are very well-known and reliable.

The Conclusion

The world of 3D printer filaments is very dynamic. A new 3D printing material is developed very rapidly and hence it is also exciting.

So, while buying TPE, you are advised to correctly check some of the most basic requirements such as extruder temperature range, heated bed temperature range, print speed and shore hardness.

Noting all of that would mean lesser mistakes and help in facing challenges while printing using TPE filament.

Moreover, check with recommended retraction settings which will decide the stringing nature of your TPE 3D printed part.

Objects printed using TPE filament will have flexibility as well as durability. But also ensure that the filament you are buying does not turn out to be extra soft or flexible.

Otherwise, it will be extremely difficult to load its spool in your printer’s spool holder. Also, with the increasing popularity of the material, more and more brands are into manufacturing of the same.

So, it’s highly advisable to be a little choosy while you are buying. Look keenly for brands that offer easy storing conditions and printer settings that are suitable for your 3D printer.

If all goes well, you’d be able to manufacture some of the most delicate parts that will exhibit rubber-like qualities.
