PLA 3D printer filament is one of the most commonly available types of plastic alongside ABS and is known for its low required printing temperatures and resistance to warping. However, this particular plastic is temperature-sensitive, meaning it changes between two different colours when exposed to heat or cold. This makes for a truly exciting filament to print with, and opens up an endless amount of possibilities for printing fun.


The Advantages of PLA

PLA is an ideal type of plastic for beginners, as it is both safer and easier to use than a majority of other plastics. This, however, doesn’t mean it’s not appropriate for advanced projects, as veterans also utilize PLA for a wide variety of applications. What it does mean is that PLA is a great starting point before trying out more difficult plastics like ABS and PETG, as it allows more margin for error, with wider temperature ranges and an easier-to-manage Melt Flow Index. This directly translates to smoother and more stable prints, with very little testing and learning required beforehand.

For basic applications like printing figurines or small objects, PLA also offers a more visually attractive finish and, due to the less malleable nature, offers a shinier, smoother appearance than ABS. The only downfall of PLA is that it has a lower melting point, meaning that it can’t be utilized for printing parts that will be exposed to high temperatures – as it will likely melt, warp or distort. With that said, however, PLA tends to warp less during printing, since the differences in printing and cooling temperatures are less extreme.

Available in a wide range of translucencies and colour saturations, PLA is a great plastic for 3D printing almost any object that will not be exposed to heat. With all of the benefits mentioned above, as well as higher printing speeds and lower layer heights, there is good reason why it’s one of the most popular and commonly available 3D printer materials throughout the world.

As a final note, you may also want to take a look at our range of PLA+ filaments, which offer almost all of the benefits that PLA does, as well as a host of others.

Typical Applications for eSUN PLA Filament - 1.75mm Thermochromic Blue:

Compared to standard filaments or even Exotic Filaments, this plastic is designed to change from white to blue as the temperature rises or falls. This can make for very exciting and unique projects, and many of our customers have been delighted with the results in the following, as well as other, fun projects:

  • Creating semi-persistent signage that appears when exposed to warm sunlight, and then vanishes when the sun goes down.
  • Printing an analogue temperature sensor that changes colour according to the temperature within a container like a lunchbox – letting you know when your lunch is getting cold.
  • Making coffee cups that change colour when the coffee within them is warm, and possibly even displaying an image to warn you of when it’s getting too cold to drink.

With the properties of temperature-sensitive colour changing filament, the possibilities of producing truly unique and exciting projects are endless. So consider getting some of this filament with your next order, and play around with all of the different functions that temperature-sensitivity can offer.

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.
