I have not learned how to design a brick wall surface using other software so I thought I could design the texture in Aspire, with a narrow "Z" height, then print that Aspire design, then glue the Aspire print on to the side of the wall.
I have made several attempts to make the raised brick style in Aspire, export as a STL, then try to 3d print, but can't seem to make this happen. The printing goes all wanky and makes a big blobby mess.
I have done several Lithophanes created in Aspire then exported as a STL and printed on my 3-D printer. The thinnest point was less than 1mm (.003") and they came out good. When exporting you have to Close the Back Face of Triangulation with a flat plane.
Although I have a commercial grade 3-D Printer and everything is automatic, I bought one of the kids a $400 3-D printer and the printing sometimes goes all wanky and a blobby mess. It's because it requires rubbing a dry glue stick on the platform so the material sticks.
