As an experienced Maker, you may have tried your hand at some of the popular 3D Filament materials on the market, using PLA for aesthetic and decorational purposes, while taking advantage of the high strength of ABS for functional prints. However, if you want to enjoy a more unique style of 3D Filament, then TPU is certainly one of the most unique around, and is designed with a high level of flexibility to give it extra mechanical strength in real world applications, and a lot of extra fun for the more playful types of prints out there. It is a thermoplastic polyurethane, which means that it fits right between rubber and plastic, and this results in a filament that can flex, bend, squish and more depending on the style of the print and the infill used. This makes TPU Filaments unique even among other filaments, and is certainly a good polymer to try if you’re looking for something different, or just want to have fun with your 3D Printer.

Although you may have noticed that a large majority of TPU designs on popular sites like Thingiverse will primarily be designed just for fun, TPU can also be quite an impressive functional filament to use as well, for brackets that need a little more flex than what PETG or ABS Filaments offer, for dampeners that need to take some force while still staying upright, as well as many other useful applications that can easily be utilised in the real world. This is why, in addition to printing loads of flexible creatures like the classic “Flexy Rex”, we also like to use TPU for handy applications like high-grip robot wheels, rubber feet for 3D Printers, door stops and many other useful things that we can use around the office and home. This high level of functionality, coupled with the incredible fun that TPU can offer, makes it an awesome material to have on hand for when you need it, and with SunLu’s range of TPU filaments being available in a wide range of different colours, you can find the style that best suits you, ultimately providing fun, functionality, aesthetics and personalisation to whatever projects (or desktop toys) that you’re eager to print.

Of course, as with any other filament brand, we encourage you to test out SunLu TPU Filament for yourself, and if you enjoy the colours, print quality and easy printing style of it, then take the next leap and test out other materials from the SunLu Filament Range. So far we’ve enjoyed each and every variant that we have in stock, and we’re quite certain that you’re going to fall in love with SunLu just like we did when first sinking our teeth into their range of materials and colours.

Helpful Tips for Printing with SunLu TPU Filament:

3D Printing with the highly flexible TPU polymer is a fun, yet potentially difficult task, but is not quite as difficult as many of the popular sources would have you believe. It may certainly take a little bit of trial and error to get just right (and some patience too), but the results are incomparable, and no other filaments can achieve the same unique properties that TPU and TPE can.

However, if you really want to get the most out of your TPU prints, and enjoy durable and stretchy filaments that really add a whole lot of character and fun to any design, we always recommend finding as much information as possible, which is why we’ve got this awesome collection of external research for you:

  • TPU Printing Tips – The Infamous Direct Drive Myth: If you’ve ever done research on or have investigation the exciting but often-tricky TPU filament, you will have certainly seen at least one resources suggesting that TPU printing is impossible with a Bowden setup. However, while this used to be true in the past, this is no longer the case with the more recent models and iterations, and modern Bowden-style desktop 3D Printers now offer a far more constrained filament feed-path, making them more than just capable of printing with flexibles, with some 3D Makers even suggesting that it’s a better setup compared to the older direct drive setups. So if you’re a proud owner of one of the many Creality 3D Printers since as far back as the Creality CR-10S model, you can rest assured that printing TPU is definitely a possibility that you can enjoy, opening up many new opportunities for printing unique, exciting and memorable 3D prints.

  • TPU Printing Tips – Speed Kills (Good Prints): When dealing with a new filament (or even one that we already know) it’s always tempting to try to print it as quickly as possible, since time is money and the majority of us are cost-conscious 3D Makers. However, printing TPU too quickly is the easiest way to kill a good print, since TPU demands substantially lower speeds than standard polymers like PLA. This is primarily due to the high level of flexibility and the ability of the filament to compress and stretch, which can easily lead to clogs and other problems as the filament bends over itself and tangles within any open spaces it can feed. This is why it’s important to print slowly, allowing the filament to steadily move without too much speed-related friction, encouraging it to behave nicely and avoid bending or tangling between the filament drive gear and the nozzle.

  • TPU Printing Tips – Retraction & Backpressure: In a very similar fashion to the previous tip, it’s important to also get right is retraction and backpressure, since flexible filaments tend to have a slight amount of delay when moving within a constrained filament feed-path. This delay is caused by the compression and expansion of the filament in conjunction with the high levels of friction against the walls of the feed-path, and is precisely why you want to minimise retraction distance and speed by as much as possible, wherever possible. With a high level of retraction, the push and pull action on the filament can happen too quickly, and if the TPU is still hot when this happens, it can easily get stuck along the walls of the cooling tower or Bowden tube, leaving inconsistent chunks that can result in clogging or oozing. Of course, retraction is a lot more complicated than many other settings on a 3D Printer, so be sure to prepare yourself for a bit of trial and error when you get started printed with TPU, and consider even leaving retraction off until you have all of your other settings dialled in just right – then move on to experiment with how retraction can improve your results.

  • TPU Printing Tips – Keeping Your TPU in Tip Top Shape: With most of the common filaments like PLA, ABS and PETG, keeping them stored safely and out of reach of humidity and moisture is not too vital, as most of those filaments are relatively neutral in terms of how easily they absorb moisture from surrounding environments. With some filaments, however, such as TPU and Nylon, it’s imperative that you always try to keep them as isolated from humidity as possible. Of course, you don’t necessarily need to invest in expensive (and often unnecessary) specialised filament drying containers, but it is a good idea for get yourself a nice container to keep filament in, and then simply throw any spare sachets of desiccant (Those small silica gel packets you get with new shoes) into the box to remove excess moisture from the small space. This will help keep your TPU filament safe from moisture, which will prevent any bubbling or weaknesses in the filament as it’s being printed.

As a final note, it must be said that TPU, TPE and other Flexible Filaments are some of the more difficult polymers to print with, so it’s important to go into this with an open mind and a willingness to learn from mistakes. However, with that being said, modern machines like the Creality Ender 3 Pro and Creality CR-10S Pro V2 have made printing with TPU so much easier than ever before, and with a bit of trial and error (and patience) you can easily learn to create your very own flexible keyrings, desktop toys, cable holders and even shoes!
