We got excessive wear and tear in the standard tank using High Temp Resin.
During the first print (High Temp V2; layer thickness = 25µm) in the new standard tank occurred excessive wear and tear (picture below).
Here’s a snippet from the Formlabs website which seems to indicate that a standard resin tank will start to fog more quickly with HT Resin than with the standard resins:
TIP:
When printing in High Temp Resin with a standard resin tank, observe the clarity of the elastic layer and replace the resin tank more often.
Since it occurred during the first print and especially in the areas of the support-structures, I assume, that the laser used too much power to build them. But I am not sure if this could be the reason or even is possible
As you see above we printed to two nearly similar parts that were angled by 35 degrees in the same axis. The angling resulted in an linear increase of “Support Height / Length”.
The excessive wear correlates with this (blue arrows).
It shows also that there was no visible wear in the first layers (obvious since it was a fresh tank).
I hope that illustrates how uncommon this case is.
