What is Additive Manufacturing?

Additive Manufacturing (AM) is a process to create three-dimensional 3D objects layer by layer with each layer adding strength and stability.

The additive manufacturing process

Additive Manufacturing is the process of joining materials to create objects from 3D models. AM is more precise, so objects can be made with closer tolerances and also allows for greater flexibility in design, as objects can be made with more intricate shapes and features. In addition, AM is typically faster and less expensive than traditional manufacturing methods. It is increasingly being used in a variety of industries, from aerospace to healthcare.

In Additive Manufacturing, successive layers of material are deposited until the entire object is built. Depending on the specific process being used, the layers can be fused together through melting, sintering orUV curing. This offers many advantages over traditional subtractive manufacturing processes, such as milling and turning, it allows the creation of complex shapes and structures. Additionally, Additive Manufacturing can be used to create lighter weight objects with improved strength. The technology also reduces waste material as only the required amount of material is used for construction. As a result, additive manufacturing has the potential to revolutionize the way products are designed and manufactured.

Benefits of additive manufacturing

Enabling design freedom

Additive manufacturing technology is enabling engineers to design parts with features and complexity that are not possible using other methods, it can incorporate intricate features, such as conformal cooling passages, into a design. The technology can grow parts as a single piece, which makes for greater strength and durability. Additive manufacturing technology does not have the limitations of traditional machines and allows for greater design freedom – It is changing the way engineers design parts.

Reducing production time

This technology has numerous time saving advantages over traditional manufacturing methods. For example, there is no need to create dies or fixtures, and changes can be made quickly and easily mid-stream. Parts can be manufactured directly from a 3D CAD file, eliminating the need for costly and time-consuming fixtures or dies. In addition, changes can be made mid-stream with little to no interruption in the process.  As a result, this technology is ideal for quickly creating prototypes or low-volume production runs.

Reducing weight and material

In the past, designers have had to choose between creating parts that are strong and those that are lightweight. However, with the advent of additive manufacturing, it is now possible to create structures that are both strong and lightweight. By incorporating organic structures into their designs, designers can eliminate substantial weight while maintaining the part’s strength and integrity. In one recent competition, an existing bracket was redesigned for additive manufacturing, with the winning entry maintaining the strength of the original while reducing the weight by 84%. 

Additive manufacturing provides an opportunity to rethink design for weight loss, as it allows for the incorporation of organic structures into designs.

3D Printing vs Additive Manufacturing: What’s the Difference?

Additive Manufacturing, commonly known as 3D printing, is a process of joining materials to make objects from 3D model data. Synonyms for Additive Manufacturing include additive fabrication, additive processes, additive techniques, additive layer manufacturing, layer manufacturing, and freeform fabrication.

Despite the widespread use of the term “3D Printing” in the popular press to represent all additive manufacturing processes, 3D printing actually refers only to a subset of AM processes that deposit material through a print head, nozzle, or other printer-like mechanism. 3D printing is typically used for small-scale production or for prototyping, whereas additive manufacturing is commonly used for industrial applications.

Additive manufacturing also offers a wider range of materials that can be used, including metals and ceramics. In addition, additive manufacturing generally has a higher degree of accuracy than 3D printing. As a result, additive manufacturing is often used for precision components or high-strength applications.

Additive Manufacturing FAQs

Answers for your most asked questions about Additive Manufacturing. Learn how Additive Manufacturing works, its processes and its applications.

Additive Manufacturing (AM) is the process to create 3D objects layer by layer with each layer adding strength and stability. Additive Manufacturing is an emerging and innovative manufacturing process that is fundamentally different from conventional manufacturing processes and is helping research and industry to explore entirely new possibilities.

In additive manufacturing, an object is digitally defined by computer-aided design (CAD) software that’s used to create .stl files which essentially “slice” the objects into ultra thin layers. The 3D printing process starts with a digitally defined object that is sliced into ultra-thin layers by computer aided design (CAD). These information guides how a nozzle or print head deposits material on top of each succeeding layer; it can be done either mechanically with lasers & printers as well when using electron beams for selective melting in beds of powdered substances like powders inkjet printed all over its surface.


Additive Manufacturing is the way forward for innovation and creating new products at a rapid pace. It’s becoming increasingly popular because you’ll save money with reduced material waste, energy consumption during production runs which are often cheaper than traditional methods (and can even be done without any human power), saving on inventory costs as well since there isn’t always need to stock up large amounts of raw materials like plastics or metal alloys beforehand.

The benefits don’t stop there though! You’ll save time both during production as well any pre-production steps necessary (such getting funding etc.). This makes it easier when optimizing legacy parts because all dimensions need aren’t just one set but many possibilities allowing us more versatility while still maintaining accuracy so they fit properly.

Additive manufacturing has made it possible for designers and engineers alike, to produce physical objects on-demand with no waste or excess inventory at an almost limitless cost savings compared traditional techniques that require complicated setup processes – all while speeding up production time considerably.

Benefits Of Metal Additives?

Create metal parts with internal voids which can improve the strength-to-weight ratio of the final product that are lighter, stronger, and more efficient than those produced using traditional methods.

AM isvery precise

3D printers can produce objects with very precise dimensions, whereas traditional methods often result in slight inaccuracies.

AM is more versatile

3D printers can produce a wide variety of shapes and sizes, whereas traditional methods are often limited to simple geometric shapes.

AM is more affordable

Metal 3D printers are available at a fraction of the cost of traditional methods, making them an attractive option for dental laboratories on a budget.
