Hello
I would like to simulate the mechanical strength of an ABS part with 100% fill.
I didn't find exactly what I wanted in Solidworks that could do this but I saw that you could make your own material: when I searched I found that, for ABS in printing, we had elastic modulus values of 114 MPa (+/- 14.2 MPa) and a breaking stress of 19.5 Mpa(+/- 2 MPa).
Is it relevant to carry out a study with a material customized with these values, if not, what would be the best solution?
Hello
3D printing with what technology? I don't think that the material can be considered "homogeneous" (especially not in wire removal.)
The values you give seem relatively high to me, to be confirmed...
Hello
I share the previous message, in wire removal, here are some readings after tests carried out in the laboratory:
theoretical maximum stress of ABS 47 MPa, but it is important to keep in mind depending on the manufacturer............. from 20 to 30 MPa, and you have to go through tests on your printed design to validate this real "manufacturer" value.
I am affected by this problem with different materials, you can modify your design to guarantee you a greater margin, I go through the optimization in simulation, see my cap printed in the forum, it is a solution to consider or to evolve the material.
It requires a lot of time and exchanges with the customer and defining its use, have a good day to you.

To read, this is a relevant study with laboratory tests on a ULTIMAKER.
In attachment, the ABS part your question.
, a mistake , was missing 195MPa (+/- 2 MPa) but 19.5 MPa (+/- 2 MPa).
I use the FDM method and the material is not homogeneous and even less isotropic and therefore depending on the printing geometry, tensile strength, compression etc... of the room is different.
I noticed that when you pass an ABS part through an acetone vapor chamber it improves the mechanical performance, maybe by pressurizing a little it would give better results. The room should not spend too long in the room otherwise it will deform, 15 minutes is enough.
The study is very interesting, thank you!
