3D Printing Tech Tips: How Much and When to Use Infill

In a previous blog 3D Printing Tips: Infill Percentage and Pattern Explained, we talked about the basics of infill percentage and patterns in 3D printing. Generally, the higher the infill percentage, the stronger the print, the longer it takes to print. Using open market 3D printing software , such as the Simplify3D, one can easily generate infill pattern and adjust infill percentage based on the application requirements. Take this 3D printed shadow board as an example, we used more infill in selected areas to provide added strength and less infill in other areas to save print time and material.

But how to decide when you need infill and when it’s not needed? YouTuber shares his take on deciding when and how to use infill in a 3D print. Watch his video, and see how you can reduce 3D print time and weight by adjusting infill usage.

Another great video to learn more about 3D printing infill:
For many, infill percentage is a held belief, same as political affiliation, religion, and camera brand manufacturer. I think that, as a whole, we can reduce the amount of plastic we use by reducing our infill percentage. — 3D Printing Nerd

In this video, one of 3D Platform’s favorite YouTuber 3D Printing Nerd explains why you need to stop wasting time and plastic on infills. In fact, most of 3DP’s sample large format 3D prints have infill percentages of 10% or less. Watch this video and consider dropping your infill a few percentage points and see if your model still works. Most likely, you’ll use a little less plastic, and you’ll still have the strength you desire.
