Q: Can this be used to generate reinforcement for plastic objects?

Open Kreyren opened this issue 3 years ago • 2 comments

I am trying to find a solution to generate these reinforcements for my plastic designs in FreeCAD to optimize them for material consumption and with declared properties -> Can this addon be used for it?

Assuming working with 100% infil i am expecting to generate reinforcements alike:

Isogrid (https://en.wikipedia.org/wiki/Isogrid)

Designed to reduce elasticity (https://en.wikipedia.org/wiki/Elasticity_(physics)) and prevent plasticity (https://en.wikipedia.org/wiki/Plasticity_(physics)) of an object mainly used in aviation and rocket engineering.

Simple explanation with highlight of the designing issue https://www.youtube.com/watch?t=670&v=Qu79vUbcXCU

NOTE: The circles in the middle of the triangles are important.

This one is supposed to be inspired by isogrid, but also optimized for faster fabrication on a 3D printer as the shape has one start and one end for the extruder to follow a path without having to lift up and relocate thus saving time.

NOTE: The provided image is proof-of-concept these shapes should be fully integrated in the reinforcement instead of being separate as that defeats the purpose of this reinforcement: 2021-12-27_04-13

Hi @Kreyren,

The FreeCAD Reinforcement workbench is basically used to add reinforcement (rebars) in the concrete structural elements like footing, beam, column etc.

From the above description, what I get is that you want to attach this pattern on the surface of the sheet to strengthen a part object.

Currently, this type of feature is not implemented yet. But we can write a FreeCAD Python script or develop a tool that will add/attach this pattern on the surface of any object.

That would be cool, thanks for working on this.
