FDM Design guidelines

[gadgetfreak 7]

I found this when googling for various FDM stuff:

https://www.solidconcepts.com/resources/dg/fused-deposition-modeling-fdm-design-guidelines/

It seems specific for the SolidConcepts company/processes/machines but is general enough as to have value to us Ultimaker operators I think!

Here is an example from the page:

"Threads

When designing built-in threads, avoid sharp edges and include a radius on the root. Sharp edges can be stress concentrators in plastic parts. Creating an ACME thread design with rounded roots and crests has been found to work well when using FDM. Also, use a “dog point” head of at least 1/32 in. (0.8 mm). This dog point design makes starting the thread much easier. Small threads produced from the FDM process are not recommended and not possible for holes or posts smaller than a 1/16 in. (1.6 mm) diameter. An easy alternative is to use a tap or die to thread holes or posts.
