3D printing is a fast growing and evolving area. So what are some advantages of using 3D printing? That ultimately depends on what you want to do with it. We'll break down some uses you may run into.
One large upside to 3D printing is the ability to create concept products and "work out the bugs" before the item is released. You may have a fantastic idea but in the real world it doesn't quite work properly, yet.
On the other hand, you may have a product that works great in the real world but by using it you may find ways to improve it before going to market. We've all had those moments when we do something and realize later that, if given the chance, we'd change or improve it, if we could go back.
3D printing makes product and concept development a lot easier and cost effective. You want to get it right at the cheapest price possible. Well before anyone else sees it. Design, test and print your concepts before running up larger costs from manufacturers.
A big advantage is the ability to create a single print of something without paying for minimum runs, which can be very costly. It's perfect for personal items or even a birthday and anniversary gifts.
3D printing is very reasonable in pricing. Especially compared to alternative methods. Creating the artwork for the model is the tricky part. Bear Toe Designs can help.
3D printed models can be created quickly.
Short answer No. Longer answer No. 3D printing is growing everyday, on Earth and beyond. 3D printing is rapidly becoming an essential part of space exploration and everyday life.
