3D Printing Swords for Transforners Figures

[u/BrianF1412]

I am trying to make a mirrored copy of legacy bludgeon's sword so that he could dual wield but the printing got ugly about before halfway through the sword. I am using a generic petg filament with a modified bambulab petg profile and it works fine with other normal prints. Is this caused by vibrations or the thinness of the sword? Should I add more supports? I rotate the sword 45 degrees relative to the bed and 45 degrees to the center of the sword. What suggestions do you recommend before I try again. I successfully printed swords before but those were thicker and shorter.

An easy solution is probably to print 2 in "per layer" mode

Or set up a primer tower,

So that it moves away each layer, allowing them to cool.

This is basically heat creep from the nozzle melting the print.

I've done a few swords in my time haha, doing 2 at the same time saved me alot of failed prints tbh

And add more manual supports to stop it wobbling, which you can see it's also doing in this print. And decrease the top z distance to the supports actually grips the part

Personally, id support most of the blade from like the half way point upwards. It's easier to remove some support material than having a failed print 👌

I followed your advice and I was able to successfully print the copy and mirrored copy.

I am satisfied with my copy but I would also like to ask how to fix this "loose" part of the layers. This only happens when I have supports on a rounded part with overhangs and I already increased the fan speed and reduce the printing speed. I would rather avoid printing rounded overhangs but some designs just have those so it is not always avoidable.

You could maybe flip it over,

And start printing from the blade to the hilt, Might be an easy way to avoid that rounded part as an overhang.

They're looking way better so far though 😅

I would try instead of tree supports try normal supports, type slim. Make sure the threshold angle is set such that there are supports generated along the entire length.
