Topic: Design rules

Hi,

I am trying to compile a list of design rules that could/should be followed in order to successfully model and manufacture a part by 3d printing. As we are aware, 3d printing has given us more freedom in the design state, however, it has its limits, for example there has to be a minimum wall thickness , or overhangs should have support structures, etc. I believe some rules will apply to certain technologies, materials or features.

Anyway, what rules do you think we should follow when designing for 3d printing?

Looking forward to your replies.

Re: Design rules

Design rules depend on a bunch of factors. What type of printer you're using changes what is considered acceptable for part design.

Re: Design rules

Also, what software are you using?  CAD, some form of Polygonal modeler?  This can have an effect on how you design.

Re: Design rules

One thing I noticed - I had to re-think how I felt a part needed to be printed - which side was "up."

Several designs I had to print upside-down to print with no structures. And/or, to get the best strength depending on the way the "grain" (layering) went.

Along the same lines, many of my designs have had to be built in several pieces to print without supports. (Which I generally despise, they ruin the cool 3D printed texture)
