External Supports not rendering in print.

Fri Jul 26, 2019 6:36 pm

Hi Everyone,

I am personally new to the 3D printing universe! I am having a couple issues actually, and I am sure they are related. I have a couple parts of my external support that will not render near parts of the actual model.

I downloaded a model I purchased from Heroforge I am currently trying to get printed. Its beak is not supported even though it actually passes the Max overhang limit, and where the part juts out for a pack on this chest, it just doesn't provide any support between those layers. That includes sections where there are shoulder pads and the arms are under them.

Please pardon the unprofessional images, I just needed something to illustrate the issue.

When I print this, it goes good up until the arm cuts off the support and when it reaches the continue point, it just creates "Silly string" in mid air and then "sticks" it to the outer layer of the model making it look... Hairy.

Any help would be greatly appreciated!! Thank you!

Could you please post the Factory File these images are from?

Are you asking me to upload the original model?

I actually tried printing it, and it will heat the bed to the temp I set it to, get half way through heating, and then it just stops. No warnings, no errors, nothing.

We do not necessarily need the model file but the Factory File will contain the settings you are using. The Factory File is a unique file compiled in Simplify3D. The file contains complete information about your project (model, printer, process settings, etc.). To create the file, open the software and load your project. Then go to File > Save Factory File as...

The possible solution to the issue with the supports is to:

Change the Support Pillar Resolution to 1.0mm
Open the Customise Support Structures window
Click on "generate Automatic Supports"
View the simulation of the supports to identify areas where auto supports have not been generated
Using "Add new support structures", add supports to areas where the auto-process missed

Note that if you can't add a custom support indicatot then supports are not possible due to the angle of the surface, etc.

Re your not being able to get the model to print at all.....that's an issue with your settings, and the best way to get assistance would be to do as Alex has suggested. Point to mention.....make sure your model and profile are loaded before you save the Factory file! If either are missing, its a waste of effort....
