Markforged just announced FEA simulation for their 3D printed parts. You can apply simulated load cases to your parts and validate their performance before printing. They even optimize your part to print faster and cheaper while retaining the strength requirements you need! They have a free trial running right now so you can try it out yourself all in-browser.
As someone who writes simulation code, I am excited to see simulations to become more ubiquitous.
For people looking at cloud-based simulations: simscale might be a good start as well.
