Bellow are some raw photos of my first test of IC-142.
Models were sliced with Print Studio because I don’t like the supersampling of Netfab very much.
I used the default IC profile with only modification the tray rotation speed, I reduced retract to 6 RPM and approach to 8 RPM.
I need to point out that a measurement of wall thickness modeled at .65mm measured .7mm with IC-142.
I should also add that working with IC-142 was very pleasant, the viscosity is quite low which (should) help more with printing, but it also makes it rinse easily. Grinding the supports was fantastic, the material is crisp so it does not clog the abrasives, and can even be polished. Although the black color helps with surface inspection, I don’t appreciate it very much. It kind of makes the model look cheap… If it was something maybe a deep purple instead it would be way more flattering and give added “value” to the model, not to mention it would make it distinct from other not castable materials. I realize it’s vain to discuss colors of a sacrificial material, but I find even these details are important in my line of work.
After the unsuccessful print, I repeated the job with B9E, using the same tray, re-shuffling the pieces and adding a couple more. The walls I measured came at the modeled thickness of .65mm.
I m looking forward to read CPS’s comments, as well as other users feedback.
