This can be printed in Resin or FDM (Better on Resin). No supports needed. Current scale is what I believe to be close to showing accuracy, but scale as you please! The "demascus" pattern may become more pronounced the large the model is scaled. If printing on FDM, I printed with the small button face on the build plate and it worked fine (Should already be oriented this way)! For resin, you may know how to orient it better than I do!
Here Are the Settings I Used to Print: Nozzle: I printed with 0.4 with no issues, although a smaller nozzle or smaller layer height would probably make it look better on FDM. Infill/Perimeters: On resin I printed hollow, on FDM I printed with 10% infill. Supports: None
Post-Processing/Assembly: I tried a couple of different methods for post-processing between silver rub n buff, and different black and silver paint to try and achieve the steel look. The best in my opinion was the Resin print, painted with black spray paint, then given a light coat of silver acrylic paint.
Future Plans/Other Notes I would eventually like to design a more show-accurate version as far as the pattern goes, although I am pretty happy with this one. I may also experiment with the pattern depth to make it still highly visible, but less "textured." Let me know what you think of the current design!
