Fixing STL Files With Errors .
Ensure your 3D CAD Models are ready for 3D Printing with these tips and a step by step tutorial .
To set the scene with an analogy . There’s a book that a number of people have recommended to you , it has all the answers to solve this particular problem you have . The only issue is that the only copy of that book you can find is in another language , though luckily you found a loose translation . You open it and flick to the chapter you need , it starts off – ‘Cooking when the party is of new intellect and has no room to move.’
… What the hell does that mean ? Unfortunately the rest of the book is worded the same and almost useless to you .
The raw data used for 3D printing parts are CAD files. As 3D printing ( as it’s commonly known ) becomes more widespread and accessible, more people who are your everyday hobbyists, inventors, gadget gurus and even school kids will begin to think of things to make, and they all start creating parts .
This means we have a lot of different file types being sent around, but in terms of 3D printing there is one that has become standard, the humble STL ( STereoLithographic ). This is what ‘3D Printers’ use, then with some material and a bit of heat ultimately ends up as a physical part in your hands. Being such an important piece of the puzzle you want to get it right, and often there is nothing wrong with your modelling skills. However, a problem can creep in when the software you use exports its native file type into an STL.
This problem is that the mesh ( the surface geometry of the part ) may not have been generated correctly and you end up with a ‘loose translation’. This means that subsequent software programs don’t understand what the mesh is trying to be and do the best they can to make sense of it , usually with a lot of errors .
