web-based analysis

Failed or incomplete prints are quite common. To avoid nasty surprises our tool is able to pin point weaknesses in your file. Don't invest time and effort we will fix your 3D model files for free. There is no need to download expensive CAD software or to register. The automated reparation tool will directly detect and repair your file if it contains misarranged meshes.

The most common errors in 3D models





Holes in the model


If a 3D model is in a good state it exhibits no “leaky” spots, i.e. it is free of any holes. Unfortunately, these leaks often appear quite easily. In this case, the 3D printer has difficulties to distinguish between inner and outer parts of the model. This has consequences: misprints, crashes of the printer and/or wrongly printed models.

Fix holes



Our repair service automatically detects such holes. Depending on their sizes, it creates one or more triangles to fix the model as good as possible.


Unconnected planes


The surface of a 3D model consists of a number of triangles with edges that are shared with other triangles. Often unconnected edges and complete free planes appear inside a 3D model file. This can confuse 3D printers and lead to erroneous printouts.

Fix unconnected planes



Free floating, unconnected planes are detected and removed by the repair service.


Flipped normals


A normal vector defines the orientation of a triangle's surface. It may point in- or outwards of the model. The normal vectors can be visualized as arrows pointing away from the surface in a 90° degree angle. In many models, these normals are oriented wrongly what causes the printer to interchange inner and outer parts of the model.

Flip normals



Wrongly aligned normals are automatically flipped by the repair service what enables the printer to distinguish inner and outer parts correctly.
