Interesting technique to strengthen protruding parts on a 3D print

[Bryan Eckert]

Watched this last night, interesting technique:

I watched the vid. In my opinion and in my experience you may get a little more strength matching where the extending element meets the base, but you’ll get way way more strength simply by orienting the part so that layer lines are perpendicular to the shear. As such overhangs are created which is yet another reason why the uncompromising approach of full contact supports is always a primary part of my task flow.

I agree, although I wish he had tested just extending that peg through the base. If the weak spot was the junction, that would have fixed it.

Also that test print would have been a good subject for a 45 degree slant print, no supports needed.

Kinda makes you wonder… was the guy so focused on only the point of increased strength via more fusion contact…

Or

Was he just clueless about a way more optimal  approach to print the part?…

Toobers.

He’s very knowledgeable I’ve watched a lot of his other stuff. The part he was having issue with had round pegs of varying diameters, and they needed to be perfectly round, which is why he was printing them as he was. 

I commented he should do another round of testing, where the walls for the peg embed down to the base. Should probably also make the pegs at a 50% infill to give a little flex.

What about a small hole in the center of the peg, turning it into a tube. You can then have walls on the inside and outside ( unless your diameter is too small ). You can even make the depth down to the floor, embedding the pin in the part so to speak.

I have used this, but do not have any measured data.
