3D printing vs traditional manufacturing

When it comes to manufacturing, there are two main methods that have dominated the industry for decades: traditional manufacturing and 3D printing. While both approaches have their own advantages and disadvantages, the rise of 3D printing has sparked a debate about which method is superior. In this article, we will explore the key differences between 3D printing and traditional manufacturing, and discuss the benefits and limitations of each.

Traditional Manufacturing

Traditional manufacturing, also known as subtractive manufacturing, involves the removal of material from a solid block to create a desired shape. This method typically involves processes such as machining, milling, and drilling. It has been the go-to method for centuries and is still widely used today.

One of the main advantages of traditional manufacturing is its ability to produce high-quality, precise parts. With the use of advanced machinery and skilled operators, traditional manufacturing can achieve tight tolerances and smooth finishes. This makes it ideal for industries that require intricate and complex components, such as aerospace and automotive.

However, traditional manufacturing also has its limitations. It can be time-consuming and costly, especially for small-scale production or prototyping. The process often involves multiple steps, including designing, tooling, and setup, which can lead to longer lead times. Additionally, traditional manufacturing is not very flexible when it comes to design changes. Any modifications to the part usually require significant rework or even starting from scratch.

3D Printing

3D printing, also known as additive manufacturing, is a relatively new method that has gained popularity in recent years. Instead of removing material, 3D printing builds objects layer by layer using a digital model. This allows for greater design freedom and flexibility.

One of the biggest advantages of 3D printing is its ability to create complex geometries that would be difficult or impossible to achieve with traditional manufacturing methods. This opens up new possibilities in various industries, including healthcare, architecture, and fashion. 3D printing also eliminates the need for tooling, which can significantly reduce costs and lead times, especially for small production runs or custom parts.

However, 3D printing does have its limitations. The process can be slower compared to traditional manufacturing, especially for large-scale production. The materials used in 3D printing are also limited compared to the wide range of materials available in traditional manufacturing. While advancements have been made in materials, certain properties such as strength and durability may still be better achieved through traditional methods.

How to get started with 3D printing?

To start 3D printing, first, figure out where you can use it. Maybe you need it for making tools or prototypes for a Kickstarter campaign. It can also help with making things custom. It’s a good idea for any business to think about using 3D printing to be better than their competition. If you’re not sure how to start, you can talk to experts at PCBway.


After you know what you want to make, you’ll need a 3D model file, usually in a format called STL. This file tells the 3D printer how to make your object. The more detailed your model, the more triangles it will have. You can use different software to make your model depending on what you’re making. There are free options available, or you can buy a model if you don’t want to make one from scratch.

How to design for 3D printing?

Some 3D programs can be tricky to use, and even if you know how, it doesn’t mean you can create a 3D model that works well.

To get the best results when 3D printing, you need to follow the rules for the materials and methods you’re using. Not following these rules is the main reason for printing problems. It can make your file unprintable or create a flawed part. To make sure your printed part is strong and works like it should, you need to design it carefully.

Pay attention to things like how thick your walls are, which way your surfaces are facing, and make sure there are no parts that overlap confusingly. Also, watch out for models that aren’t properly connected – these can cause issues too.

How to 3D print your model?

Once your model is done, it’s time to print it in 3D! You can do this with your own 3D printer if you have one. Most likely, it’s a small one you keep on your desk. But have you ever thought about using a bigger, more powerful printer?

Industrial 3D printers are really expensive. If you don’t want to spend that much but still want professional-quality prints, you can send your file to a 3D printing service like PCBWAY. They offer lots of materials and finishes to choose from, and you’ll get a price quote right away. Industrial Additive Manufacturing is perfect if you need strong, high-quality parts for your projects.
