I recommend this video by CNC Kitchen, as it shows an interesting, accurate and detailed, side-by-side comparison of heat deformation of custom 3D printed test samples, printed from various materials:
- PLA
- PETG
- ABS
- HT-PLA
- 3dkTOP
He even CNCs a custom, yet simple, test rig in order to carry out the test.
Well worth a watch.
The results for the various filaments can be seen in this graph, taken from the video:
In summary, the annealed 3dkTOP filaments perform very well, without failure, and annealing PLA helps considerably (although some shrinkage is incurred)
