This tolerance is defined as the maximum distance between the original shape and the STL mesh you are exporting. OpenSCAD is a free 3D CAD program that works well. Mostly for print and video, never for anything physical like 3d Printing. I might try that first, as it doesn't require a download or even a login. in 123d I would fill in the hole with the merge union (with a cylinder object), scale it, and either keep it unfilled and drill it, or do a subtraction union on where you want the holes.

The smaller these triangles are, the smoother and more detailed the surface of your model will be… and the bigger the size of your 3D file. It's worth mentioning that this works for OP's case of an empty vector, but if your vector already has elements, this will not resize the existing ones, so you will only get the exact desired dimensions if your existing elements are already of the desired dimensions (for instance, this will not properly resize an existing 2x2x2 vector up or a 10x10x10 down, but will work for a 1x5x10). In this blog post, we will take a look at how you can reduce the size of your 3D model files and what level of detail you should be aiming for in order to get a high-quality 3D print.

Tip: Ember uses a parallel 3D printing technology, it prints the whole slice in one go. resize will invalidate all iterators, pointers, and references into the std::vector if and only if the new size is larger than the current capacity of the container (i.e., v.capacity()).. Model available for download in # format Visit CGTrader and browse more than 500K 3D models, including 3D print and real-time assets Open>Select file type as STL Step 2: Select options Step 3: Import as>Solid body , you can also select units in which the part was made actually. We can also scale the individual size of selected objects instead of scaling the distance between object along with the scaling of the objects themselves. Need a little context here: there are lots of things called meshes. OpenSCAD, as mentioned above, is pretty well established as an open source tool for modifying STLs; however you have to be comfortable writing programmatic CAD instead of using GUI tools. For example, you can give the free 3D modeling program Meshmixer a try.

When exporting a file with a tolerance larger than 0.01 mm, triangles might become visible in the 3D print. File size is mostly a problem for programs that use NURBS modeling (meaning they express mathematical models). 3D files can be heavy, very heavy. Try this for yourself by printing multiples of the same object, as long as the Z height of the print job is the same, the job will take the same time! Then you can adjust the value and export a new STL. So if you choose the right tolerance here, you can be sure that your exported STL mesh will be perfectly printable and won’t look pixelated.
