ColorFabb PLA/PHA printer settings

Here are some tips and tricks on how to use ColorFabb 3d printing filament.

Advised 3d printing temperature: 195-220C*

Advised 3d print speed: 40 – 100 mm/s

Advised Heated bed (if you have one, not strictly necessary): 50-60C

Build platform
The PLA/PHA filament performs well on both heated and non-heated build platforms. For those users printing on a cold build platform ColorFabb advises to apply 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. For direct printing on glass or aluminum ColorFabb advices to apply glue-stick. A very thin layer will be sufficient to keep your print in place. Another method is dissolving wood glue in water. By applying just a few drops and smearing this out before you start heating the built plate will create a very thing layer which holds the PLA/PHA down very well. If applying this method, be careful that you do not get your electronics wet.

Another method that works well with colorFabb PLA/PHA is polyimide tape, or Kapton tape. This tape is available as a very narrow strip or very wide strips which allows you to cover the build plate in one go. When the tape is applied correctly it can last for months.

TIP! Take your time leveling the bed and adjusting the gap between 3d printer nozzle and build plate. A perfect first layer is very important, especially for 3d prints with a large bottom layer. Having the nozzle set too close to the build plate will cause a pressure build up and as a result back flow in most hot ends.

TIP! PLA/PHA has very minimal warping tendencies, however if your printing parts takes up the maximum of your buildspace you might see some warping. If it is very important that your part is perfectly flat, we suggest to turn 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 needed.

*3d printers have lots of different types of hot-end which makes it extremely difficult to give one temperature advice. ColorFabb temperatures advice holds for most 3d printers, but should be considered as a starting point to find the temperatures that work in your setup. Do not be afraid to go either higher or lower then their advised temperatures if you feel your set-up needs this.
