Inspecting Parts And Solution - Stratasys FORTUS 360mc Manual

Inspecting Parts and Solution

Support material can be washed away from part geometries in 0.5 to 3.0 hours
in the support removal tank solution using proper temperature (see
Temperature" on
solution for less than 24 hours should see no change in mechanical properties.
Polycarbonate parts left in the tank for excessive periods of time (greater than
24 hours) may see a 5% to 15% drop in mechanical properties. It is highly
recommended to avoid leaving polycarbonate parts in the tank solution
longer than 24 hours. This will alleviate any potential degradation of the
part's mechanical property.
Various factors determine how long it takes to remove support material in the
tank. These include the following factors:
• Minimize the volume of support material on the part (see
"Manually Removing Support Material" on
• Minimize the time parts are in the solution tank.
• Maximize the pH level in the solution tank.
• Maximize solution agitation around parts
For best part quality, inspect parts as follows:
1.
Inspect parts after two hours and then periodically until complete.
Because of air pockets and circulation patterns, rotate the basket or
free moving parts to dissolve support material faster.
2.
Inspect the tank periodically for over-heating and solution
evaporation. The solution level must always cover the parts. Add
more water if necessary. DO NOT add more soluble concentrate.
Note: Adding more soluble concentrate than recommended
can damage parts.
