To Print a Model in 3D Using a Printer
1. When you have a model open, click > 
Print > 
Prepare for 3D Printing. The Tray tab opens and a new tray assembly is created, with your model as a part of the Model Tree. Alternatively, you can create or open a tray assembly file.

2. Select a 3D printer from the list of printers.
3. To view information about the printer, click > 
Printer Information.

Manage Appearances and apply colors to your models.
Manage Appearances and apply colors to your models.5. To set up the printing options, and start the additive manufacturing process, click 
Preview 3D Printing. The 3D Print tab opens.
Preview 3D Printing. The 3D Print tab opens.6. To change the STL resolution, follow these steps:
a. Click 
Tessellation Options. The STL Parameter Definitions pane opens.
Tessellation Options. The STL Parameter Definitions pane opens.b. For each model you want to modify, change the required STL parameters, click Apply, and review the changes.
c. Click OK. The STL Parameter Definitions pane closes.
7. To slice the model, support structures, and lattice:
a. Click 
Slice.
Slice.▪ If more than one CLI file is generated, the Export Zip dialog box opens. All the CLI files produced by the model are saved in a single ZIP file.
▪ If one CLI file is generated, the Export CLI dialog box opens.
b. Type a name for the CLI files next to File name, and click Save.
c. When the slicing succeeds:
▪ The Display Slices viewer opens.
▪ A CLI file or a ZIP file that contains the CLI files is created in your working folder:
▪ <CLI_name>_B.cli contains the data for the model geometry
▪ <CLI_name>_<feature_name>_L.cli contains the data for the lattice
▪ <CLI_name>_S.cli contains the data for the support structure
See To Slice a Model. You can display slices by clicking 
Display Slices. You can load slices by clicking 
Load Slices.

a. To set the export options:
a. Click > 
Options. The Creo Parametric Options dialog box opens.
Options. The Creo Parametric Options dialog box opens.b. Click Additive Manufacturing. The additive manufacturing settings page opens.
c. To export the model bodies, lattice, and support structures as separate STL files, select the Export body, lattice, and support separately check box. When selected, you can also choose the following option:
d. For models that contain more than one body, to export each body as a separate STL file, select the Export each body in a separate STL file check box.
b. Click 
Export.
Export.▪ If more than one STL file is generated, the Export Zip dialog box opens. All the STL files produced by the model are saved in a single ZIP file.
▪ If one STL file is generated, the Export STL dialog box opens.
c. Type a name for the STL files next to File name, and click Save. An STL file or a ZIP file that contains the STL files is created in your working folder:
▪ <prefix>_<body name>_index_B.stl contains the data for the model geometry
▪ <prefix>_<lattice name>_index_L.stl contains the data for the lattice
▪ <prefix>_S.stl contains the data for the support structures
9. To view the interior of the model and the support material at various points during the printing process, click 
Clipping and use the 3D dragger to display the interior of the model.
