Free stl viewer helps in making your model 3D print ready

MiniMagics can help you in making your model 3D print ready when you have a model in STL format.
A summary of the features of MiniMagics is available at the download site.

But especially 1 feature can allow you to save precious time.
A model has to be ”watertight” before we can 3D print it.
Watertight means that all edges of the triangles of which your model consists of need to have a mutual edge with another triangle.

When the model is not watertight, our i.materialise service might not be showing a price online.
Our server tries to ”fix” the uploaded model and make it watertight automatically but when the gaps between 2 edges of triangles is too big, the fixing process might fill up the hole in a way that it effects the geometry of the model too much. So we limit the fixing within the boundaries that it is safe to fix.

Why don’t we show prices for models that are not watertight ?

Models with bad edges or holes will produce incorrect price parameters and hence inco
