colorFabb Natural PLA/PHA 3D Printer Filament – 1.75mm / 2.2kg Spool

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.

Natural PLA/PHA works great for investment casting and has a proven track record for high quality printed patterns which deliver a clean burnout.

Buttery, creamy and super smooth. It’s a great neutral color which is just a slight bit translucent, which helps hide the layer definition.

Our PLA/PHA Natural has a proven track record for high quality printed patterns which deliver a clean burnout between 400C and 850C.

Build platform: colorFabb’s PLA/PHA filament adheres well to both heated and non-heated build platforms. We recommend using BuildTak as your bed’s printing surface.

If printing on a glass bed, apply glue-stick. A very thin layer of glue will be sufficient to keep your print nicely in place. Another gluing method is dissolving PVA glue in water. The consistency of the mixture can be quite thin, like skim milk. By applying just a few drops and smearing the mixture out before you start printing will create a very thin layer which will hold the filament down.

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 is important that your part is perfectly flat, than we suggest slowing the fan that is cooling your part. This allows the material to slowly get rid of heat without warping. After a few centimeters of layers have been printed, you can turn on the cooling fan if the part needs it

*3D printers have a wide variety of hot-ends which makes it extremely difficult to provide a universal printing temperature. The provided temperature range should be considered a starting point to help you find a temperature that works for your print. Please refer back to your printer’s operating manual for safety and temperature specifics.
