I bought my first 3D printer a few weeks ago, a P1P, and I’m enjoying its use immensely.
However having built a Pulltruder I managed to get some quite reasonable filament from plastic bottles, but I can’t for the life of me manage to print with it ! I’ve tried creating various print profiles from the standard PETG one, but whatever parameters I set, particularly temperature, they won’t “stick”. The actual hotend temperature won’t go above 220degrees. Do I have to alter some G-code somewhere ? Or anything else I may be missing.
I’m using Bambu Studio, and have tried manually forcing the temperature up, but it has no effect.
I’m assuming that it is the low temperature that’s stopping the extrusion process, since nothing pokes its head out of the nozzle !
Since I’m new to the wonderful world of 3D printing, I’d really appreciate some help please. Ideally a P1P-specific set of print and filament parameters would be fantastic - I could then learn from that. (I did buy a hardened steel hotend assembly, but that makes no difference either.)
Thanks for that Kevin, I was beginning to think that nobody loved me.
Since my original post, I’m beginning to think that I’m somehow falling foul of the various “User Presets” anomalies. I’ve edited existing presets and saved them as User Presets, but even though they appear in the assigned AMS slot on the “Prepare” page, those settings seem to be ignored.
I’ve read a great deal about User Preset problems, but I’ve still no idea how to get them to actually print. The User Presets don’t appear on the “Device” page, so they can’t be checked, edited etc. I assign the correct AMS slot, thinking that the correct settings will be used, but no, the actual print temperature never matches the preset’s one. So I can’t get a high enough temperature to print recycled PET.
I suspect I’m missing something very fundamental, but it’s got me stumped.
Has anyone actually managed to print PET with a P1P? If so, please tell me how please!
Mate how have you got on with this? My work (college education) just won some money to purchase the 3 machines from. 3devo and I’m researching best ways to print recycled drinks bottles as we try to become more sustainable
I’m scared to use one of the 6 new x1c printers we have and might try out on the 3 old dremel 3D45 printers till I’m sure I’ve got it right
Any advice you’ve got let me know search me on Facebook we can chat more if you want
I, too, work in higher education and have been tasked with looking into recycling bottles for filament. Would you be open to a discussion about this topic? I can email, teams chat, or give you a call.
You can email me at danielleadams@upike.edu if you would like, but I don’t precisely shine via text. I process auditory information better and quicker than I do text.
I can set up a teams video meeting (or zoom) if you would like or, you can give me a call at (606) 218-5605, I am free until 2 today.
I am in the initial research phase of the project to see if it is even feasible. We only have a Bambu x1c that will print the recycled filament.
We are looking at purchasing the polyformer kit to make the bottle recycling machine.
Hi, printing from PET to X1C is without major problems. I recommend starting from the PA-CF print profile and gradually tuning the values - personally, the print temperature of 285°C has worked well for me. You need to set the flow rate to 130-140%. Filament good to dry after production.
The only serious complication is the necessity to manually flush the nozzle with new material after printing (I use PETG), as the filament is still stiff in the nozzle at 250°C with automatic filament change. So heat it up to 265°C+ and manually extrusion with new filament.
It wouldn’t be bad of BambuLab to allow to adjust the heating temperature when changing filament manually…
I tried what you suggested about starting the custom filament with PA-CF, but the Bambu Studio simply won’t allow me to create the filament without an existing preset, and there’s none for this one. What would you suggest? Could you maybe share your print profile?
