Please Note: eSun has recently changed their filament spool material. You may receive a cardboard spool, instead of the plastic spools depicted above. This move means a more environmentally friendly design to their 3D filament spools which comfortably sit on your 3D printer's standard spool holder for smooth filament feeding.

If you enjoy experimenting with new polymers and colours in your 3D Printing adventures, but aren’t eager to learn a whole new set of printing specifications for different types of plastic, eSUN’s eSilk PLA Filament is an exciting addition to our catalogue that may certainly pique your interest. Designed with the easy-printing base polymer of PLA, and enhanced with polyester-like additives, eSUN’s eSilk filament offers very cool aesthetics while still maintaining the great properties that make PLA so easy to print with.

These spools are Blue, although we also offer a range of other colours like Violet and Jacinth, as well as standard White that can be painted with your own custom colours after printing – often resulting in beautiful models, accessories and art pieces. In terms of what prints are good in this uniquely silky blue PLA, we have found that almost every print we’ve tried has looked fantastic. And while many of the other Silky PLA Filaments tend to lend themselves well to specific applications or themes, this brilliant blue is a great all-rounder to have spare, for times when you want a fancy silky colour, but don’t want to commit to such a striking colour like Jacinth or Violet.


What Are the Best Features of Silky PLA Filament?

When talking about Silky PLA, the best features are quite subjective, and will depend on what your favourite factors are. However, the first and obvious amazing feature of Silky PLA is that the prints produced with this filament immediately look a lot nicer than standard PLA prints before any post-processing is done. In addition to this, Silky PLA also offers some unique benefits that many people don’t yet know about, and these include the following three distinct advantages that we’d like to tell you about:

  • Despite looking somewhat soft and fluffy at first glance, Silk PLA actually offers less shrinkage than standard PLA. This is in part because of the polyester contained within the polymer, but is primarily because of the low glass transition temperature, which allows the filament to set for a slightly longer time before hardening into a defined shape.
  • Again, despite the soft aesthetics of Silk PLA, it actually offers better toughness than standard PLA, which is due to the polyester additives providing better layer adhesion, flow capabilities and reduced stringing – resulting in a better overall polymer structure that can be bent, flexes or stretched more than standard PLA before it succumbs to permanent deformation.
  • Finally, and this doesn’t quite pertain to structural aspects, Silk PLA Filament offers the distinct advantage of maintaining near-perfect colour after printing. And whilst standard PLA often changes colour slightly depending on a variety of factors, from print temperatures to print speeds and even uncontrollable factors during the polymerisation process, the natural glossiness of Silk PLA directly translates through to the printed object, offering almost the exact same colour integrity before and after printing.

Of course, as with any 3D Filaments or other materials from other industries, there are also negative factors for Silk PLA, although the only real noteworthy negative factor is that Silk PLA has a lower temperature resistance than standard PLA. This means that Silk PLA is likely to start sagging and eventually melting when left in hot or sunny environments, although this factor is somewhat negligible since even standard PLA will do the same, but may just a slightly longer time to do so.

Typical Applications for eSUN eSilk Blue PLA Filament:

In addition to amazing aesthetics and almost soft, smooth finish that eSilk offers, this unique filament is also somewhat self-lubricating as well, and we’ve had relatively high success in using eSUN eSilk for parts that need to slide or move with low friction. Just remember that the addition of the polyester-like material means that eSilk is slightly less durable than standard PLA Filaments, but it can certainly offer unique benefits for specific scenarios or purposes. Aside from that though, eSUN eSilk is primarily just designed for beautiful aesthetics while offering the same print quality and ease-of-use that you’re accustomed to with regular PLA.

If you’re looking for unique and exciting 3D Filaments that don’t require any extra learning or specific hardware, then you should definitely try our range of eSUN eSilk Filaments.

eSUN eSilk PLA Filament - 1.75mm Blue

Shenzhen eSUN Industrial Co., Ltd was established in 2002 in Shenzhen Special Economic Zone and has rapidly become one of the leading international suppliers of 3D Printing Filament. They specialise in research, development and production of degradable polymer materials, and have grown their catalogue of filaments to include PLA, ABS, PC, PVA, and a wide range of other polymers and copolymers.

Their list of exclusive filament formulas include unique materials like wood, aluminium, bronze and other materials to create highly specialised filaments that can stretch, bend, be moulded or otherwise behave in very unique ways. Their filaments are also commonly characterised by their absolutely round shape, extremely low diameter tolerance, uniform colours and impressively stable melting points. These characteristics, in combination with their long-term insistent policy of “Best Quality, Reasonable Price” has garnered them a large share of the market, with their reputation commonly preceding them within knowledgeable online and offline 3D Printing communities.

eSUN’s popularity in the industry has also helped to produce sustainable partnerships with many internationally famous 3D Printer manufacturers and distributors, with DIYElectronics having sole distributorship rights to provide their 3D Printing Filaments to South Africa and neighbouring African countries.
