Understanding Additive Manufacturing and CNC Machining

What is Additive Manufacturing?

Key principles and processes of 3D printing

Additive manufacturing, commonly known as 3D printing, builds objects layer by layer. The process begins with a design created using computer-aided design (CAD) software or by scanning an existing object. This design is then sliced into layers using specialized software. The 3D printer follows this framework to deposit material, forming each layer until the object is complete. The thickness of these layers can range from 10µm to 200µm, depending on the machine and settings. This layer-by-layer approach allows you to create intricate designs that would be impossible with traditional methods.

Advantages of additive manufacturing in material design

"With additive manufacturing, you produce — layer by layer — pretty much any geometry you want to create. You can create 3-D entities that are much more complex and have different material properties."

Additive manufacturing offers several advantages:

• It enables the creation of complex geometries, such as hollow structures, without compromising strength.

• You can improve part properties and produce lightweight components.

• It supports rapid prototyping, allowing you to iterate designs quickly.

• The process reduces material waste and energy consumption.

• It facilitates customization and distributed manufacturing, making it ideal for both high and low-volume production.

What is CNC Machining?

Overview of subtractive manufacturing processes

CNC machining is a subtractive process where material is removed from a solid block to create a part. Automated tools, guided by computer instructions, cut, drill, or mill the material with high precision. This method is ideal for industries requiring tight tolerances and intricate designs. CNC machining works well with metals, plastics, and even wood, making it highly versatile.

Precision and material compatibility in CNC machining

CNC machining achieves exceptional precision by cutting materials with sharp tools. The choice of material depends on its properties, such as hardness, toughness, and machinability. For example:

• Hard materials like stainless steel maintain sharp edges during machining.

• Tough materials, such as titanium, withstand energy without breaking.
