+==== Easy evaluation of .stl-data ====
+Especially when using files downloaded from open internet sources it may be that these files are not suitable for printing due to export or modeling mistakes. Misaligned edges (non-manifolds) and holes can render a 3D model unprintable and make troubleshooting on the 3D printer an infinite displeasure because no obvious reason can be detected.
+One quick and simple way to eliminate this as an error source is checking the suitability of your .stl-file for 3D printing. All you need is a program capable of analyzing the .stl-file's mesh.\\
+Slic3r itself can deal with minor troubles and the [[http://www.netfabb.com/|netfabb company]] offers a [[http://www.netfabb.com/downloadcenter.php?basic=1|free basic version]] of their //netfabb studio//, an .stl-handling tool with repair functions. Other tools may be as helpful but these two are used to explain how to recognize a corrupted file.

+__Slic3r part info:__\\ (see [[http://manual.slic3r.org/advanced/repairing-models|Slic3r manual]] also)\\
+After opening a file in Slic3r, the info box in the bottom-right corner of the plater shows information on the model status. For a single, suitable part the info must look like:\\
+''Factes: xxxxx (1 shells)''\\
+''Manifold: Yes''\\
+If it displays ''Manifold: Auto-repaired (xxxx errors)'' the file contains degenerations.\\ It is most likely that it also shows an increased number of shells (e.g. ''Facets: xxxxx (6 shells)'' because the part has been split.\\ Also check the 3D preview for visible defects. In this case it is better to repair or reconstruct the model.\\ Regard that the auto-repair function of Sic3r is only suited for repairing minor defects.

+__Evaluation and repair with netfabb basic:__\\ (see [[http://www.netfabb.com/manuals_download.php|netfabb basic manual]] also)\\
+If you open a (supposedly broken) .stl in netfabb, the program will display a red warning sign in the bottom-right corner when the part is indeed faulty.\\ To see mismatches, run the part repair function by clicking on the red cross sign in the toolbar or via the //Extras// menu. The part is analyzed and all mesh information are displayed, including holes, invalid orientation etc. You can try using the auto-repair function or manually repair defects (very limited in the basic edition) to correct the part prior to newly exporting it as .stl.\\
+\\
+If simple repair does not lead to satisfactorily results, redesigning or renouncing this specific part and choosing another one may be the best choices.

 ==== Print bed leveling ====
-The PEI print beds delivered with every RepRap Industrial are custom-made specially to our needs. Due to the manufacturing process, they may show bends and curves which can make handling them a bit tricky. These flaws are accepted due to the superior properties of PEI compared to other subsurfaces when printing ABS. Follow the tips given below and you should have no trouble achieving perfect results.\\
-Of course, the PEI print bed is, like the whole RepRap Industrial, optimized for printing ABS. It also works fine with HIPS, PET-Copolyester, PVA and thermoplastic urethane (TPE-U). Other materials may require a different subsurface, be it another material or a special treatment with tape or glue. Find more information about materials and printing them with a RepRap Industrial in our [[reprap-industrial-v1:knowledge-base#materials|Knowledgebase]].
