How To Print Polypropylene PP Filament

Getting started printing on the X1C

  • Filament is FormFuture Centaur PP Polypropylene - Natural
  • Print bed used was the engineering plate with pp polypropylene tape applied
  • Printer is X1C
  • Ocra Slicer

Tips:

Start off with a low temp melt filament like pla before you load the pp filament into the extruder and nozzle. We don’t want to grind up the pp filament.

I like to use a window film tinting squeegee to apply the pp tape to the bed plate. This helps to minimize the air bubbles in the tape.

It is recommended to use the external filament loading. It is a soft material and can grinded up in the AMS.

Printer Settings = Before layer change G-code

What this G-code will do is set the bed heater to 23c on long prints to help stop big parts from warping off the bed.

 ; Polypropylene filament Bed Heater = Set your bed heater cut off layer mm height
{if layer_z>=5.00} M140  S23{endif} 


.
Printer settings = Extruder

.

Printer settings = Motion Ability

Setting the extruder with a low acceleration for the soft pp material

.

Filament Settings = Filament

I put PETG type do to no pp in menu this will work


.

Filament Settings = Cooling


.

Filament Settings = Advanced

Remove the G-code chamber fan settings we will be using the Ocra fan G-codes


.

Process = Quality


.

Process = Strength

Can select the wall loops 2 or 3 works for most PP parts


.

Process = Speed

12pp
.

Process = Others

I have printed a few parts with all these settings I do use my other printers to print with the pp filament but I had seen people having problems and wanting settings to start with so I hope this helps you out so you can now print this type of filament on the Bambu lab X1C :smiley:

Thanks a lot for your findings!
Do you keep the build room as closed as possibel or wide open?

I read both😅
