Blender 3d printing
Hi, A customer has purchased this product:
They wish to 3d print the model, however I did not design it with 3d printing in mind. Is there a way to edit the model so it can be 3d printed or is it a lost cause?
I did this recently for a customer.
It can be done, but requires a lot of work and depends on a lot of factors.
I agree with Trimitek. Any model can be made to 3d print with the right editing, but there are some cases where it may be impossible to get all the details translated to a real-world print. Small details that are only established through textures, like normal map details, will not print. Any smoothing which does not affect the geometry will not print (for example, surface normal or angle based smoothing). In some cases, it could require a lot more effort and time than it's worth, depending on how much you stand to make from it.
Try to start from voxel remesh this model in Blender's sculpting module (in some if not in most cases before of it "Solidify" modifier applying is needed before of doing something in sculpting module).
Voxel remeshing in Blender is sometimes slow and buggy process, but at the end it gives very good STL mesh without critical errors or issues.
One of the most important things to keep in mind for 3d printing is the thickness values of each part based on the type of printing that will be used. A good rule of thumb is that most 3d printers have a minimum thickness tolerance between 0.8-2mm. I usually like to make parts at a 2mm thickness just to be sure it works under the widest range of printers, but sometimes that is not going to be possible if the object is very small scale. So stay within the 0.8mm thickness for everything at the very least.
