This is one of the most flexible TPU filament available in the market right now. But that’s not the only amazing thing about this product in the case of printing.

Among several other TPU filament for 3D printing, this one stands out because of this product’s low-odor and low-warp build. You can easily use it on several projects, and they will perform in top condition.

Most of the filaments available on the market right now suffer from this odor problem due to the extra heat that they go through. But you won’t face that problem with the TRONXY TPU.

Being brittle can be quite an issue when you try to print something flexible, but due to this product’s softer texture, you can customize more when it comes to construction.

PST. Here’s how to fix brittle filament to avoid any major printing issues.

The unit also has an adjusted degradability of the material so that the performance is always optimal no matter the heat rate or whatever condition it is being used in.

Maintaining the diameter is quite crucial if you want clog-free distribution from the nozzle. Therefore, due to the unit’s assurance in maintaining a consistent round diameter, you get a very smooth flow.

During packaging, the filament needs to be moisture-free, so the vacuum seal is excellent in that scenario. You can use it right off the packaging without any issues.


  • Adequately adjusted degradable material.
  • High-temperature tolerance level.
  • Vacuum sealing packaging.
  • Free from hazardous substances.

Another vital thing about filaments is that they need to be vacuumed appropriately so that the filaments do not contact moisture. That helps in the case of printing and proper dispersion.

That will help you make better components and get more strong structural integrity. And that is very important for most projects as TPU filaments are typically used for their constructional strength.

The strips’ diameter is another important thing when you want proper distribution through the nozzle since, without that, you get more clogging and more mess.

But due to the highly accurate diameter of this product, you really don’t have to worry about sudden breaking or clogs. Eryone tried to ensure that every bit of the strip is balanced correctly.

If you’re interested to know about the spool, then this is the 1.1-pound variant. You can typically use it for smaller projects, but these are great for large ones, too, since they won’t finish too quickly.

The proper distribution ensures that every product is being used and none of them are wasted in any given scenario. No matter how long they are used for, you will always get the most efficient performance from it.


  • Has an outside diameter of 1.75-mm.
  • Amazing translucent color combination.
  • Easy to handle.
  • Efficient nozzle dispersion.
  • Reduced clogging and breaking.


  • Sealing can be inefficient.

This can definitely be called the best TPU filament because of its longevity compared with other materials. It lasts much longer and capable of withstanding more stress than any typical material.

In the case of handling stress, it is much more reinforced with the high flexibility rate. You can compress it any way you want without permanently damaging the form of the item.

Roundness is very important if you want your nozzle to perform appropriately while ensuring that the dispersion is done so that it doesn’t get clogged or stuck on the nozzle.

Consistent diameter also comes in handy in such scenarios, as if you have a constant diameter, the flow would be much smoother, and you’re able to build products without being interrupted.

Another interesting fact about this product is that it is made from a specially formulated thermoplastic polyurethane that upholds a technology that allows it to have an easy-to-feed texture.

When it comes down to hardness, this product has a shore hardness of about 85A, which is quite flexible while keeping a stable and robust form. After drying up, it can basically handle more stress.

Keeping your eye on the tensile strength is quite essential if you want durable and strong products. Tensile strength measures the amount of pressure the project can handle.

You might want to go for a TPU filament that can take about 26Mpa of tensile strength. That will help you make supporting components and components that can stay in shape even in extended uses.

If you don’t go for something that doesn’t check that box, you might be at risk of breakage or anything along the lines since the supporting components made from that will not last that long.

Therefore, tensile strength is needed when you want something that will have longevity under extreme pressure.


High elasticity is the most important feature for any product that is the competitor for being the best TPU filament. Most of the product you will make using TPU filaments they need to have high flexibility.

That will help you make items like hand bands, flexible phone covers, and anything along that line. Otherwise, they will break way too quickly, and they won’t be able to stretch as much as you need them to.

Therefore, you might want to go for something that will have an amazing stretch rate since that will also prevent deformation when you stretch the items made from the TPU filament.

An elastic modulus of about 7.8 MPa is quite enough to handle most stretch. That will also help the items to hold their structural formation.

Most people might overlook this at first, but this is crucial when you want proper dispersion from the nozzle without any resistance. Otherwise, in the long run, it might be quite inefficient.

Since inconsistent TPU flow can cause the nozzle to jam and even cause clogs, that will make a very messy situation in very little time since the dispersion needs to be quick.

So, you might look over if the flow is consistent or not; otherwise, you might get problems in the long run, and things might be quite hard to clean up.

In some scenarios, there might be an interruption in the flow that will cause structural damage to the things that you’re trying to build. That will make the project lose its integrity and deform.
