Rhinoceros is a good software to build a 3-D model and print it .
After desiging, don't forget to form a nurb format of the model and you can choose the detail level of your model
Then choose the model that you want to print and save it as a .stl document
Then open the document in the printer's software :XYZware and set the variables -- especially 0.2mm layer height
Apply the solid gum on the printing area and the margin!!! Before the formal printing, it will try to lay out the material at its margin. If you don't apply the solid gum , the bottom of your product may be ruined.
When it finishes printing, wait until the table cools down and use the plastic scroop to fetch your product. Don't forget to clean the table!
