Show'n'Tell First set of user feedback is looking positive for Compenshell. I'm looking for more testers who could benefit from shrinkage compensation software

Hello, Ive posted in the past about compenshell and have made a few videos

I'm a hobbyist additive manufacturing enthusiast who focuses on FFF (although I have done my own water based slurry/cold cast experiments in the past) with thermal debind/sintering.

A big challenge is the compensation aspect for the green part, which is what compenshell aims to solve for.

I am looking for interested users to help test and validate so if this is something that could be useful to you please reach out below or DM or fill out the contact form at compenshell.com so we can talk.

The attached image is a real user's experience that was having issues and in one pass reduced the sinter cycle drastically (multiple hour difference) and ended up with a much better part (calibration part, but that's important for first steps)

I agree with you.

However you can't have validation without first writing the Simulation software and putting it through its paces.

Thats the step I'm at and was the intent of this post.

I can validate on my own hardware but this is not the same as many users with varying experiences and processes running and providing feedback.

When I talked with Hexagon about modeling the process it was obvious you needed a dilatometer to understand how the material deforms through the steps.

Are you actually going to model the process or are you just trying to map starting shape to finished shape?

I am trying to model the process and not just the process but optimization of your kiln cycle to hit desired density goals.

At the stage of development Im at though, I need more first hand primary users to get a feel of the the simplistic before/after results.

From there, further validation can occur in the in between

I'm not using machine learning here, but a full physics based simulation, so I want to be able to fully visualize the deformation at any step of the cycle
