This video introduces and categorizes common printing problems and discusses diagnosis techniques when both printer hardware and printer settings may be at fault.
- [Instructor] One of the things that makes it very challenging sometimes to diagnose what's going wrong with a 3D print is that the problem can be a complicated interaction with the 3D printer's hardware, its software, the printer settings you selected, the material you're using, and possible issues with your design in the first place. Teasing all that out can require both some patience and some experience. We can't help you with the patience part, but in these videos we'll teach you some rules of thumb for diagnosing what's going wrong. Let's talk through how to think about 3D printing problems you're having.
First, did your printer work in the past, and did you change something to make it not work now? Even different color filament can matter. If the only thing you've changed is the type of filament, explore the movies in this chapter about filament issues. - [Host] Next, check to see if your model is one of the special cases we cover in depth in the chapter about part geometry considerations. Prints that are tall and skinny or that have thin walls sometimes require some settings adjusted. Vase prints, which take a solid shape and make it hollow and open on top also have some special requirements.
Prints that are more solid than usual, have critical dimensions, or ones with unusual strength requirements also need some extra consideration. - [Instructor] If one of those situations does not apply to you, then you may have one of the issues described in this chapter's movies. In those, we'll look at the most common systemic problems with 3D prints. If you're new to 3D printing, the next movie, Parts of a 3D Printer, will help you with terminology and the basics of how a filament based printer works. You should watch that first, if you're unsure of what things are called.
- [Host] Is your print failing to stick to the printer's platform? That's a pretty common problem with various causes. If so, watch the three movies that explore different causes of this problem, to help you figure out what's going on. - [Instructor] Does your print have gaps or lumpy parts? You might be pushing out the wrong amount of plastic. Take a look at the movie in this chapter about over or under extrusion. - [Host] Or if your print has pimples or dimples, as we see here, or has many fine strings across open areas, you may have retraction issues.
Take a look at that movie. - [Instructor] If your dimensions just seem off some how, watch the last movie in this chapter to get some guidance about figuring out where your printer's hardware might be having issues. - [Host] Finally, some slicing programs handle certain types of prints better than others. If none of the information we've given you seems to help, consider trying a different slicing program. See the movies in the chapter about the relative strength and weaknesses of different slicing programs, for details. We will use Ultimaker Cura 3.0 for many of the demonstrations in this course.
- [Instructor] Debugging what's going on with a 3D print is never easy. The movies in this chapter address the diagnosis of some of the commonest problems that come up, and describe what to do to work around them as much as possible.
