You'll find you don't need rafts with prints like this. Let's see the finished project when you have it. I imagine you're putting that butterfly on your Harley. Which vehicle are you making inner fenders for? | |

I’ve got a list of parts for the Wraith , but want them in PTEG, so I’m going to play and practice with PLA first. First issue was prints starting in corner not center, that was one click in CURA. Hang up and Drive |

What got me was I needed to “uncheck” the center box. The factory prints are perfect, I tried two other random files and they started in the corner until I changed it. Good news the butterfly is smooth and crisp Hang up and Drive |

Been playing for a week now. I’m starting to get all the settings correct now, PLA works well for me, but I need PETG. So test, test, test. Close, but not quite perfect, bit of stringing and a few blobs, but strong . Hang up and Drive |

Do you have to coat the print bed with anything like hairspray to help the base material stay in place?

No not so far. I run it heated at 70 and PETG sticks just fine. Almost too good. I am getting some high spots that acetone isn’t cutting, need to go glass plate soon for PETG. Printing PLA is a dream on this machine, right OOB Hang up and Drive Last edited by mikemcE; 01-06-2018 at 03:02 PM. |

I have been practicing printing with a large format extruder so that I can eventually print large parts like a custom flatbed. In the video, you can see the printer laying down a single extrusion shell in a tall model vase. Finished model is 6 inches tall. |

PETG from what Im learning more of ... needs to be printed slower, hotter and with the head a bit higher up from the bed. Also not cooled as much during the print. It doesnt need to be squished down like PLA and layers stick together better if they are still close to their print temps. If youre still shedding stringies you could try slowing the head down or turning your fan down. Im at 75% right now but gonna try dropping to 50%, I get some layer splitting. Also restraction can help too with getting rid of the hairies/stringies. The vase video is perfect .... you can see it laying down the strand and not squishing it. IT actually makes me want to print one tonight as a good test for what Ive been trying. | |

Yeah 245 at 50 seems much better, the fan is not shrouded, so mine is at 100. I’m getting better, but practice will make a difference Hang up and Drive |

PETG can be difficult to remove. I hate printing with rafts, but sometimes it's necessary. | |

I too hate rafts, but with PETG the prints are much better, so it’s worth the extra time and materials. PLA doesn’t seem as finicky , no raft or brim needed. Hang up and Drive |

I practiced doing prints of 3DBenchy until I got perfect prints then I moved on to the vase. | |

I would think no flattening means the resultant print won't be as strong though. | |

If I was wanting a stronger print I would use a lower layer height and more layers. But the plastic would have a cloudy look to it. Another factor is the plastic being used, since PETT is "sticky" when hot, you have a higher layer height and still get bonding of the layers. A nice thing about 3D printing is you never run of things to learn due to all of the different options that are available. | |
