3D Printhead Thermal Simulation

Hello

I started today to document myself on a thermal simulation, I manage to obtain coherent values but at the level of the wire I don't know how to put an environment that will allow to get closer to reality, in my simulation the heat remains after the extrusion. I am already very happy with this approach.

If someone has a way to improve this area on the way out, I'm listening.

Have a good day to you.

Spectrum.

Hello @spectrum 

It's normal since you're in static so the value becomes fixed because you don't have the notion of time.

If the heated wire passed at a good speed, it would not cool down as quickly. This is what happens a few seconds (or less) after the wire feed stops

If you want to do better you should look at the flow-simulation side which should allow you to simulate the dynamic side (I don't know too much about Flow-Sim)

Wouldn't you have a mega collision that you can check with the "collision detection"

Indeed, the mesh control seems to show an anomaly on the cutting plane that should not have this head

Hello Zozo,

Not easy with Flow simulation and my model is wobbly I agree.

I changed my approach to understand how the module works, studying the Js on a barbecue.

Thank you for the possible help to put equations in objective.

Kind regards.

Spectrum.

OK @spectrum 

On the other hand, going from a printer's thermal head to a BBQ tank (gulp and why lead for the calculation of PB heat loss which is rather persona non grata      ;-)     )

Hello Zozo,

Don't worry, it's made of S235 steel, but I have a request for lead but not for cooking that would be fatal for the consumer....... To cool after immersion.

I try to find the different temperatures with the notion of time that is encompassed in Flow simulation.

I will post my results and the agreement or not....

Have a nice day.
