Hi @jejessika, thanks for posting on the Forums!
If you can provide some more information on how uniform you would need, that would help. I’ll provide some general information below.
With any print, there will be some variability in the print thickness. This comes down to:
- The accuracy of your height map.
- The flow rate that you calibrate.
- The z-axis print height target (set in the advanced settings panel during calibration or print).
- The spacing of the traces that make up the features (the pass spacing parameter).
To ensure you have an accurate height map, the most important things are to:
Make sure your substrate is clamped and flush with the print platform. Any bowing or deflecting will lead to heightmap issues.
Ensure your probe tip and the z-axis calibration switch are clean. Any buildup on either can lead to inaccuracies.
For more details on print height, I suggest reading our article on Understanding Print Height.
However, as mentioned, the manual flow calibration plays a big part in your final trace thickness. While you can do your best to keep things as reproducible as possible, the V-One is optimized for reproducing the 2D design file over maintaining a precise thickness.
If uniform thickness is a requirement for your application, I’m definitely open to discussing the specifics - we’re always collecting info on where to improve or what features to develop!
