The 3D Print Check tool checks a part for its print viability, displaying warnings or errors to the user. The checks include:
The position check examines the extents of the part and verifies that the part is within the positive x,y,z coordinate system. Use the Auto Position tool to automatically position the part within the positive coordinate system.
Facet Count Check
Some 3D printing service bureaus, cannot process more than 1,000,000 facets. If you have more the 1,000,000 facets you may need to reduce the number of facets in your model. Some options include changing the solid to facet conversion or using the Facet Reduction command.
If your model is too large or too small for standard 3D printers, a warning message is displayed. The too small message warning is displayed if the model is less than 0.3 x 0.3 x 0.3 cm.
Closed and Water Tight Check
A 3D printer must have a closed volume to print. If your model is detected to have open edges an Error alert is displayed.
To find your open edges, use the Find Open Edges command in the Mesh menu.
This check examines each facet as unique in the model. If it finds another facet at the same position, an Error message is displayed. To correct this issue, use the Delete Duplicate Facets tool.
A collapsed facet has no area. This check will inform you if the part has zero area facets.
To correct Collapsed Facets, use the Remove Collapsed Facets command.
Facet normals define the inside and outside areas of your part. If some of your facet normals are pointing the wrong way, the 3D Printer may have problems creating the part.
If you have a normals issue, there are several commands that can help you fix this problem. First use the Display Surface Normals tool to isolate inverted facets. Use the Fix Flip Normals to correct bad normals.
Some solid modeling programs allow you to create non-manifold solids. A manifold part has exactly two facets connected to each edge. If an edge has one facet attached, then the edge is open and is detected by the Closed Water Tight Check. However it is possible for a model to have more than two facets connected to an edge. This check isolates those type of edges and reports as an error.
Example: 3D Print Check
1. Select the print definitions from the Printer menu.
2. Press the Exit button to close out the dialog with the selected settings.
