Quote of comment of R.. GitHub STOP HELPING ICE on question reads: Pretty sure it is NP-complete (equivalent to travelling salesman problem), no? – This is correct; this is route optimization at its purest, and is by no means a new problem. You want to travel the shortest total distance between all vertices of what's essentially a totally-...

3D-Model Exchange Files The most common file formats to exchange models for 3D printing are STL, OBJ, FBX, COLLADA, 3DS, IGES, STEP, and VRML/X3D. Of these, STL, OBJ, AMF, and 3MF are the most popular formats according to All3DP. Pointing out which is the best is a subjective interpretation and not fit for SE sites. However, for many of the model sharing ...

Because my research shows that LAS files are point cloud data, you would first have to convert the point cloud to a mesh. Point clouds are just that, data references to points in 3d space. A printing service works with files that represent planar surfaces, properly joined (watertight, aka manifold) to form a solid or solid surface model. The only resource I ...

Any and all CAD files can be converted to STL (Standard Triangle Language). In this file format, surfaces are parsed to be combinations of triangles. For example a flat rectangular surface gets represented as two triangles in the same plane. As the complexity of the solid increases more triangles are required to adequately approximate the surface. Flat ...

Magicavoxel supports export as .obj, natively or with the right plugin. While .stl is the standard for 3d-printing exchanges, as it contains a "1-unit" length,(typically that corresponds to 1 mm), .obj is also accepted by most slicers. To get to MagicaVoxel's native export, look in the lower right corner, click export and see this pop up: Press the top-...

Here is what I suggest you try. If you have a file that you can view/edit in blender I would export it as both STL and OBJ formats. Then take those files and upload them to Netfabb (https://netfabb.azurewebsites.net/) and get a "repaired" file. Have the library try again with the repaired STL and OBJ files. If this doesn't work try to get the exact error ...

Good luck with that. Issues you will face: using a G-code editor (or built-in printer software) to create multiple copies of the object in a single print session user writing the printer file to an SD card, then block-copying the SD card defining a "print". Specifically: is #2 another functional copy of the object, or did #1 fail? Failed prints happen a ...

I've had good results with using the free web-based program known as Onshape which allows you to import/create 3D models. One of the features built into Onshape is a drawing tab. You can select the views desired or use a standard layout, as well as add dimensions to the individual drawing views. This image above was of a model created in and exported from ...

A point cloud is often derived by sampling. Each point represents an observation. Sometimes, a point cloud is turned into a surface by fitting triangles to the points in the form of an STL file. A raster is a 2D grid of pixels. It divides the area of an image into constant-sized little squares. Each of these squares has a value. A 3D raster is made of ...

I gather from your post that you are trying to export a build file containing multiple individual pieces, possibly to be printed. I suggest using the 'Merge' tool to join each of the individual STL's into one file. You can then save it as as single part or export it to a printer. This information comes from my experience as an Additive manufacturing ...

Instead of using save project as or export click save part as, this defaults to an STL file.

There are a number of programs available which will convert g-code to DXF, a common drawing format. If your device does not support DXF directly, there are a number of programs to convert DXF to SVG. I would paste links but a quick search with your favorite search engine should give you useful results. The better conversion programs will allow you to ...

Makerbot will accept obj files also. Is there an error while importing the obj file? Also you can see errors of your imported file in your makerbot It will be marked in black. Please make sure your object is a watertight mesh. As I have seen its easy to make a surface model in sketchup. A 3D Printer cannot print something in surface. You can also try ...

The marching cubes algorithm can convert voxel data into a surface mesh. A global threshold to determine the surface in the greyvalues is used. This article might be helpful.

there is a nice software to do it, a brazilian one, called Invesalius (http://svn.softwarepublico.gov.br/trac/invesalius). Itksnap is probably a better initial choise, since it is more intuitive (http://www.itksnap.org/pmwiki/pmwiki.php). But anymways, it is not a easy job to do, and probably you will need other softwares to help you clean the mesh, like ...

Double-check that your model is solid (i.e. watertight). Holes in the mesh, or (as other's mentioned in the comments) or problems with thickness can cause those issues. You can use Netfabb's Cloud Services, or download the free version of their app. There are other model repair services, too.

Yes, invesalius (free software) is the way to go. I was able to export a CT scan a few months back using invesalius to either OBJ or STL format for 3d printing (can't remember which). But i do remember i was then able to open it in Lulzbot's version of Cura (a free 3d printing slicing software). But there are 2 things to keep in mind. The image i was able ...

Blender imports all STL files as if they are a single object. If you have multiple meshes in the object that you want to be separated, you can press tab to enter edit mode, select the parts that need to be separated, then hit P and separate by selected. If you want to print those pieces as one part you have to get rid of any internal faces. The easiest way ...

Given that LAS/LAZ is LiDAR point cloud data, there is a GIS tool called las2tin to convert these files to a triangle based mesh called Triangular irregular networks or TIN by the GIS community. Other GIS tools should be able to do the same, for example ArcGIS. Once you have the mesh, Google should be able to help you find a way to convert the TIN to an STL....

Even though OpenSCAD can import a variety of formats, the file structure will not be accepted by Thingiverse in the manner presented by the OP. OpenSCAD is a text-based description language. One creates parameters assigned to specific aspects of a model and implements those parameters to create the desired shapes/components by typing in a text editor. The ...

It also works with the .photon format of the Photon slicer. It is only marginally better than ChituBox though.

Looks like you didn't include a space between the -i flag and the file, though you did include the space in this question. Try running the command but include spaces between your flags and file directories: recon-all -s mybrain -all -i /home/fsuser/Desktop/brainscan.nii

TL;DR - The problem would appear to be that some of the steps require a bit of manual tinkering in order to complete them successfully - it isn't just a simple question of conversion. So, no (not currently). Also, whilst writing this answer, it dawned on me that unless someone has actually managed to automate the whole process already, then your question may ...

Yes. You can import it into Blender, but it will need "bones" and "armature" if you want it to move at all. In Blender, you can manually add armature and "Rig" it, if you want animations. You can probably convert whatever file type the 3D model is (probably STL) to fbx with Blender For animating, start with a super basic 2-...

3D files differ greatly in size and what they contain: STL STL Stereolithography files were invented by 3D Systems to store surfaces. Originally it used ASCII text to store information by naming triplets of vertex positions for each triangle (facet). Since that got too large, newer STL are Binary, which is quite smaller. Many programs can export them, their ...

If a general-purpose compression tool using a good compression algorithm, such as 7zip or gzip (for linux and command line enthusiasts) is not providing good compression it is not likely that your files can be compressed very much. This applies to a wide variety of binary files beyond just 3D print files. There is always a fundamental limit on compression ...

Some tools like Cura or Repetier Host have slicers that analyses and tell you if it is ok to print or not. Both of them allow rotations.

I believe a point cloud is just a collection of points, while voxels - "3D pixels" - define location and a cube area. They seem to be pretty equivalent mathematically.

Just like the other already have mentioned, most likely your model has 3D printing errors. Either way, I would run it through a repairing service just to make sure it's free of 3D printing errors. I repair my models using this free automatic tool https://makeprintable.com/

You could try import it with blender. It's a free software which should be able to import the files. First thing is to go the the File->User Preferences->Add Ons tab. In the Import-Export section, enable the 3DS Add-on. After that you can export it to the desired format. Before exporting you must select the model/mesh you want to export. Otherwise nothing ...
