If someone had told you 25 years ago that 3D printing would become a reality, you probably would have laughed. Plastic has been molded for decades, which is a well-known technique. But molds aren’t always the best option for most applications. Let’s say you’re making a prototype. You’d have to create a prototype mold, which is a lot of headache and investment. Not only that, but you’d need a ton of special equipment. And for each iteration of your design, you’d have to create a whole new mold. With a 3D printer, you can simply tweak your prototype in your design software, and try again. Nowadays, it’s much cheaper for designers to go from initial design to final product.
