Unfortunately, there is no simple method for modifying specific features of an STL. I wouldn't say *any* 2d image, but rather, any flat logo or simple illustration image. Additionally, most of those very heavy files have a level of detail that are just way beyond what the eye can see or what any 3D printer can print. It has excellent selection tools, you can undo/redo selection and obviously you can resize any portion without affecting the others. 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. TinkerCad is a simple & free tool mostly intended for empowering kids but its ability to easily edit STL files makes it rare and valuable. Additionally the angle of the upper surface must stay the same. This technique cannot be used to say convert a photo. First, I imported .stl file into blender. Check out this simple guide to learn how to do it! Question about your order or your offline price request? You can do that kind of scaling in your slicer slicer without even changing the model file. I think what you are trying to do is somewhat non-trivial so whatever tool you choose there will be some learning curve. Then you can adjust the value and export a new STL. 3D files can be heavy, very heavy. When exporting a file with a tolerance larger than 0.01 mm, triangles might become visible in the 3D print. Begin typing your search above and press return to search. 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). (max 2 MiB). 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.

I am currently working on some projects and it seems that no matter how I size my projects in Blender when I export the .stl and load it onto my print bed it's a few millimeters in size. Mostly for print and video, never for anything physical like 3d Printing. over 100 high-quality materials and finishes. Have you made a great 3D printed product? Need a little context here: there are lots of things called meshes. I would suggest using Blender for this purpose. This section demonstrates the changes that occur to a mesh when exporting and re-importing an STL. say no or yes, same process as is for import of IGES/STEP. The one problem that I've had with OpenSCAD is that it will frequently crash unexpectedly or run incredibly slowly when dealing with an STL with a large number of triangles. This belongs in the External Tools section. This tolerance is defined as the maximum distance between the original shape and the STL mesh you are exporting. Now change the whole elephant into Edit mode for the UVs to appear. FWIW, I would probably break this into three STLs using a DIFFERENCE method, stretch the outer ones using a SCALE method, then use a UNION to put them back together. First thing you should do if you don’t have any way to display STL files is to download Blender and install it on your computer. How do I modify it so that it is wider and longer by a few millimeters but the screw holes stay the exact same size?
