colorFabb Traffic Red PLA/PHA 3D Printer Filament – 750g


In stock (can be backordered)

Most PLA 3D printer filament tends to be brittle, but not colorFabb's PLA/PHA.  They compound PLA with PHA to create an incredibly tough filament that prints fast and easy, even at moderate temperatures.

Bright red like the traffic lights causing everything and everyone to stop right in its tracks.

Available in 1.75mm and 2.85mm diameter.


Most PLA filament tends to be brittle, but not colorFabb.  They compound PLA with PHA to create an incredibly tough filament that prints fast and easy, even at moderate temperatures.

Approx. length on a 750g spool is 245 meters.

Excellent diameter tolerance
ColorFabb uses sophisticated and highly precise laser measuring systems to check the diameter of the filament in real time during the actual production process. It’s measured over 1000 times per second and this helps guarantee that each spool of filament is produced within tolerance. We can guarantee 0.05mm +/- for our 1.75mm diameter filament, which means you can be rest assured that your printer is extruding the exact amount of material called for.

Climate Controlled Warehouse
STACKER warehouses its filaments in a climate controlled room to protect them heat and moisture which can degrade the life and performance of some filaments.

In-house testing
ColorFabb filaments have been rigorously tested at both STACKER and colorFabb facilities on Stacker 3D printers, and this ensures the best results possible. The colorFabb test lab features a wide range of popular 3D printers, including several STACKER 3D printers. They are continuously testing on 3D printers to ensure the filament is performing in real world situations.

Material science
ColorFabb was founded as a brand of Helian Polymers, a sister company of Peter Holland which have been active in the master batch and additives for the plastics processing industry. Both companies eat sleep and dream about 3D printing, and our passion drives us to create the best user experience possible.

General Tips
Build platform

Our PLA/PHA compound performs well on both heated and non-heated build platforms. For those users printing on a cold build platform we advise applying masking tape to the build area. The rough surface of the tape will provide enough adhesion for the first layer to stick and print almost without any warping.

Users using heated build platforms have quite a few options these days. The usual suspects are glass and aluminum build plates. For directly printing on glass or aluminum we advise the user to apply glue-stick. A very thin layer will be sufficient to keep your print nicely in place.
Another method is dissolving wood glue in water, you the consistency of the substance can be quite thin, a bit like milk. By applying just a few drops and smearing this out before you start heating the built plate will create a very thin layer which holds the woodFill down very well. If applying this method, be careful that you don’t get your electronics wet.

PLA/PHA and Warping

PLA/PHA has very minimal warping tendencies, however if you are printing parts which take up the maximum area of your build space you might see some warping. If it’s important that your part is perfectly flat, than we suggest slowing down the fan that is cooling your part. This allows the material to slowly get rid of heat without warping. After a few centimeters you can turn on the cooling if the part needs it.

3D printers have lots of different types of hot-end which makes it extremely difficult to give universal temperature advice. We feel our temperature advice holds for most 3D printers, but should be considered as a starting point for you to find the temperatures that work in you setup. Don’t be afraid to go either higher or lower than our advised temperatures if you feel your set-up needs this. Please refer back to your printer’s operating manual for safety and temperature specifics.
