3D Printing My Design Appears to Have Lines Throughout It In A Non Circular Shape - Not Printing As Intended

[dwphilbrick]

I created this design to replace the cracked top of a device I have. The design looks great in Fusion360, but upon printing, the circle has lines going through it in an odd pattern. At first, I thought there was an issue with my printer but I printed the design with a raft and the raft circle came out perfectly smooth and circular. Hopefully, someone can help me pinpoint if this issue is caused from a flaw in my design or something else I am missing, that I can hopefully rectify! I included photos from Fusion360, while my printer is printing(showing the weird line patterns), and the final product(showing a very smooth raft, but the bottom of my design is very rough with lines going through it, and the top side(where the screw holes are) there are some line patterns appearing. If there is anything missing that might help solve this, please let me know!

Hi,

Printer Callibration is a BIG issue with 3D Printers.

All it takes is a knock or a temperature change and all that Precision - isn't.

Depending on what you are printing and how critical it is, it is a good idea to Calibrate before every Final print

you want. Considering it takes Hours to print most things, a few Minutes to Calibrate is worth it. Little things

can make the difference.

I was writing a Magazine Series last year and took photos during the Print. Simply opening the door to get a clear

picture caused a temperature change that made the print curl on one edge. result - failed Print (but a great example

for my Series!). Stable printing conditions also affect prints significantly.

Hope this helps.
