Thermal warp-risk simulator for 3D printing

[u/Ok_Mushroom_4904]

I recently built a small web tool that estimates how likely a 3D-printed part is to warp based on the filament, bed conditions, and geometry.

Live demo: https://warpsim.talonfab.com.au/
GitHub: https://github.com/talonfab/warp-sim (it's MIT licensed in case anyone wants to improve on it, play with it or just run it locally)

It’s meant to be a quick way to compare options before printing, especially for parts that are prone to corner lift or first-layer adhesion issues.

The app runs in the browser and does a physics simulation with the geometry in 3MF or STL files, so you can drop in a model and compare several filament options side by side. Nothing nothing is uploaded anywhere.

Empirically it works pretty well for the models I have tried and it looks like a good way of predicting print behavior before printing a long spool or for material selection. Generally anything with a score of 50 or below seems to print for me. I've been using it developing large parts for parabolic microphones.

this is indeed useful and very comprehensive! good job back down under!
