Spitfire76's Build Log of 3dLabPrint's Piper J3 Cub

[Spitfire76]

I've built several 3d printed planes from https://www.eclipson-airplanes.com/ using ColorFabb's LW-PLA but this will be my first one from 3dlabprint and I will be using their LW-PLA - https://3dlabprint.com/shop/polylight-1-0-cubyellow-lw-pla/ to print their free to download https://3dlabprint.com/shop/piperj3cub/

I'll follow Troy's build video and add my own notes in this thread.

Most of the LW-PLA printing that I've done has been on a Robo 3d R1+ that I've had since late 2019 but earlier this year I purchased a Bambu Lab's P1P

Shop Bambu Lab P1P on the official web store. The coreXY 3D printer with the open frame that opens up possibilities for endless customization. Enjoy out-of-the-box 3D printing experience with customizable and upgrade options.

With the Eclispon Models I used Cura and had the settings dialed in and so the challenge here is to have the same success using Bambu Studio and printing on the P1P. Bambu Lab's now have their own LW-PLA called PLA Aero but I will be using 3dLabPrint's Polylight as I already have a couple of reels so will use them first before trying the Aero.

PLA Aero

Bambu PLA Aero achieves low density and light weight by foaming at high temperatures during printing and creating small holes inside the prints. It's the perfect choice for light-weight and energy-saving prints, including unmanned aerial vehicles (UAVs), aerodynamic models, and gliders.

I will be using their LW-PLA printing guide though.

To obtain the files for this Piper J3 Cub you do need to login to the 3dlabprint website and effectively purchase them, but the cost is $0.

These are the 4 zip files available to download.

• PS_G-CODE.zip
• PS_3MF.zip
• S3D_Factory.zip
• 3DLabPrint Piper J-3 CUB decal sheet.zip

The first file contains the g-codes and in some cases, depending on the printer, these can be used directly. The files have been generated using the Prusaslicer and although I have not tried to use them on my P1P I don't believe that they would work but it's something I may investigate later. Another approach would be to add the P1P to the prusaslicer and use the files from PS_3MF but I am not sure how to do that and again it's something that I might check into later. My initial approach is to use Bambu Lab's slicer, Bambu Studio since its already setup for the P1P and print jobs can be sent from it to the printer over the wireless network. Also, since Bambu Studio handles 3mf files I thought that I could simply load the files from PS_3MF but unfortunately, it's not that easy. I need to research into the 3mf format some more, but my understanding is it's a standard and unlike stl files contains additional information like print settings. When I load one of the files from PS_3MF into Bambu Studio as a project I get the following message

In other words, I can load the 3mf file but only will get the same information as if it were a stl file. Not sure here who is not following the standard but its looking like Bambu Studio. I'll check into this further but in the meantime, I am just going to import the cub files as if they were stl files which means manually setting up a printer, filament and process setting in BS.

The S3D_factory.zip files contain the files for the Simplfy3D slicer which I believe is what 3dLabPrint initially used before moving to the Prusaslicer. The last file is actually a PDF not a zip file and contains the decals.

I first loaded the non-vase profile at the end of this article as a starting point for the settings/

I then installed the prusaslicer and opened the Marlin compatible direct Driver printer.......... file from this document

Slicing our models in PrusaSlicer (since version 2.4) – 3DLabPrint

PrusaSlicer developers kindly answered our call for a slicing mode to support printing our thin-wall planes...

Another error that I ran into when loading some of the cub 3mf files is this, not sure what it means but it did seem to be repairable.

I have almost completed the build, but I have neglected this build log for the last month so will try to update it over the next few days with the following topics

• Printing the parts on a Bambu Lab P1P
• Assembly
• Creating vinyl decals
• Installing electronics including an Aura 5 Lite

 

[Spitfire76]

In order to print parts with the right settings on the Bambu printer I first mapped the Prusaslicer printer and filament settings to the Bambu Studio settings using a spreadsheet. Even though the Bambu Studio is based on the Prusaslicer some names are different e.g perimeters vs shells. Also some settings exist in PS but not in BS. Then I loaded the 3mf files from the Cub one by one into the PS and it turns out that there are about 4 or so major profile settings. For example for a lot of the parts the printer profile is "0.3mm 3DLabPrint". I then made the same user preset in BS " 0.3mm 3DLabPrint @BBL P1P". I also made a user preset for the filament " 3DLabPrint PolyLight 1.0 @BBL P1P". Although there are only a few of these user presets each part may have some modifiers so I had to recreate these and finally ended up with a complete BS project like this and have one for the wings, fuse, gear etc... just to keep them at a manageble size.

Hello
I have the piper cub STL files. The 3mf files and the gcodes for Prusa are gone on the 3Dlab site, and the files are no longer in the download either. I chased down a lot of settings for the Pursa slicer and these are my major problems, not too bad, but it aggravates my OCD. Haha
I also have a Bambu P1S. I tried to use the Prusa settings in Bambu slicer and the print ended up worse. So I have to transfer from Prusa slicer to SD card to the Bambu. I believe I'm using a non foaming light weight PLA from Esun, could you upload settings that you have used for your Bambu Studio slicer. I would like to purchase some other planes from 3Dlab, but I would like the print to be corrected first. Any help is greatly appreciated. Thank you for your time.

The 3mf files and the gcodes for Prusa are gone on the 3Dlab site, and the files are no longer in the download either.

Wow, I just downloaded the zip file a couple of days ago and both the gcodes and 3mf files were in it. Try downloading the file again.

You are correct found them, thank you

 

[Mr NCT]

You are correct found them, thank you

I just ordered their filament kit for the cub. I'm excited to start printing.

What printer and slicer will you be using

 

[Mr NCT]

What printer and slicer will you be using

I built a Prusa MK4 kit (which was a lot of fun) so I'll just use the supplied G codes for the Cub. If I like the 3D printed planes then I'll probably start using Prusa slicer and experiment with their input shaping. It's cut about 40% off my normal print times.

 

[El Guapo]

Nice. Well put up pics of your build. If you come up with any info of why my prints have open spots, let me know please

 

[Mr NCT]

Just started printing yesterday. I tried using the Gcode and didn't like the results so I imported the .3mf files into Prusa Slicer and then changed the printer to my MK4. I'm getting good prints with some internal stringing but no problems so far.
