As we like to play with various materials to print 3D objects with we got some samples of 3D printer filament that glows in the dark thanks to the presence of phosphors inside the thermoplastic. We got both ABS (left) and PLA (right) Glow in the Dark samples of filament from 3DFilaPrint that is apparently being manufactured by the Chinese company RepRapper Tech. Both filaments are white in color and they need to be exposed to stronger light to “charge” the phosphors, so that the filament will be able to glow in light green color in the dark. The PLA glow in the dark filament does seem a little bit yellowish than the ABS one that looks more white under normal light conditions, so we expected that the results we’ll be getting from the two filaments will differ a bit.


After exposing both types of glow int he dark filaments to stronger light for a bit and putting them in not totally dark environment we have noticed that the ABS filament has a stronger green-ish glow than the PLA one. Both filaments were exposed to the same amount of light, so it seems that the ABS glow int he dark material “charges” faster and initially glows brighter for a brief period of time, after a bit the glow in the dark light from both the ABS and PLA filaments seems to become the same. So probably the initial difference comes from the ABS “charging” the phosphors faster than PLA, but then quickly things get pretty much even.


Do note that the light that is produced from these glow in the dark filaments is not much, unless they were exposed to strong light for a while right before they get into complete darkness. So the glow in the dark effect could be considered more of a cool effect that is not very useable, but still could be quite fun to print some stuff using glow in the dark ABS or PLA filament. A good idea would be to use this one for keychains or other stuff that might help you find something it the dark, such as a battery holder or similar. We however don’t think we’ll be needing a full spool of Glow in the Dark filament for the moment as the wraps we have will be enough to play with the filament. We do plan to soon try another interesting alternative to achieve the same effect – paint a 3D printed object with paint that contains phosphors in order to produce the same glow in the dark effect. This method could be more useful and easy to implement as you don’t need to get special type of filament, but print in any filament that can be then turned on to a glow in the dark object. The only drawback from using paint is that it may not be so durable as if you have the thermoplastic itself producing the glow in the dark effect.


We have just received our order of 3D filament wraps (samples) from 3DFilaPrint. The company is based in UK and carries many different types of 3D printer filaments and the best thing they have is the ability to order smaller 10 and 5 meter samples from pretty much the whole range of 3D filaments they carry. The so called wraps or samples give you to opportunity to try out various different materials at much lower cost and then actually decided to order or not a full spool of the material. With some more specific and exotic filaments a whole spool of filament could turn out to be quite expensive purchase just to find out that it is not what you have expected from the material. We have ordered many different samples to play with, so you can expect more details about materials such as Orbi-Tech’s Laybrck and Laywood D3, or the Taluman’s Nylon and T-Glasse filaments along many others including UV reactive and glow in the dark materials and so on. So we would recommend to anyone interested to find a local 3D filament supplier that also carries short samples that you can also purchase in order to test various new materials and see if your 3D printer will be capable of using them as well as to see how good they may fit your specific needs.
