For a rotary aligned scan, perform a fine align. In summary: For a manually aligned scan, perform a rough align, then a fine align. The remainder of the parameters are typically not needed. Max iteration number - related to target distance, it tells it when to stop regardless of target distance setting. You can also set it higher to align faster. Any smaller and you are just wasting time. equal (or slightly under) the specified error floor. This is a function of your scanner and should be approx.

Once the initial alignements are complete, drop it down to 1mm to 'fine tune' Target distance - this tells the algorithm when to stop. A value of 5 or 10 (in millimeters) is usually a good start. Typically for a manually aligned object you want this to be large enough to encompass your 'point picking' error. Minimal starting distance - this ignores any samples that are outside of this range. A small sample typically works quiet well. You do not want to make this number too big. Sample Number - this is the number of samples it pulls from each mesh to compare to the other meshes. The default ICP parameter parameters allow you to fine tune how one mesh is aligned to another. If you are happy with the alignment, click the Process button to align them even more accurately and to glue them in place. Again, they will not be exact, but should be extremely close. If the selected points were close, the two meshes should automatically align. They don't have to be exact, but be as accurate as you can. Then, choose 4 or more similar points on each mesh. Try to place them in a position that shows as much overlapping information as you can. Rotate both models around and position them in a similar manner. When the alignment window opens it will display the first glued mesh and the second mesh, both with different colors to assist in the point selection. This feature will use 4 or more user selected points to approximate the alignment of the second mesh in relationship to the first. Next, choose the second mesh and click on Point Based Glueing. This will affix the mesh to a set location and allows the other meshes to be aligned to it. Click on the first mesh file in the menu and choose Glue Mesh Here. This tool is used to reposition the separate meshes in relation to each other. Close the Layer Dialog menu and click on the Align icon to open the Align tool. MakePrintable or Materialise Cloud) in your 3D design software.You will now have three separate layers each with meshes that are not aligned. This problem can be remedied by automatic downscaling (e.g. Many cloud-based 3D STLprinting services impose upload limits on the files you can upload, ranging from 64 to 100 MB. STL Repair Tip #5: Minimize the file size Depending on to what use you will put your 3D model, you must choose a thickness that will yield a robust model at an economic consumption of filament or other material. It is paramount to set a wall thickness that can support the overall structure.

MeshLab), but automatic solutions are also available in most STL repair software tools. Scans can be reworked before printing by hand (e.g. STL Repair Tip #3: Get rid of floating surfacesģD scanning can produce unwanted fragments which result from structures or textures that are unsuitable to the process – e.g. Non-manifold geometry startles 3D printers as much as anyone else who tries to wrap his head around the idea for the first time. Typically this conundrum results from extruding but not moving faces and edges. Simply put, non-manifold geometries are identical edges directly on top of each other. STL Repair Tip #2: Check for non-manifold geometry All of our STL repair tools listed below can handle these 3D mesh problems easily.

A 3D printer faced with such a file can’t tell an outer surface from an inner surface. One of the most common errors encountered when 3D printing are STL files that have holes in their meshes – they are not “watertight”. Here are the most common design mistakes – and what you should repair so your 3D model prints correctly. STL Repair Tips: Checklist for 3D DesignerĪ 3D model isn’t automatically a 3D printable file.
