Guide To 3D Laser Cutting | IVYCNC

3D laser cutting has become the center of attention nowadays. Many businesses are adopting this latest technology and benefiting from its operations. It has revolutionized manufacturing and greatly accelerated global production lines. But how does it work? 

This article will discuss various aspects of 3D laser cutting, such as its usage, advantages, disadvantages, etc. So, keep on reading our ultimate guide to 3D laser cutting.

What Is 3D Laser Cutting? 

3D laser cutting is three-dimensional laser cutting. 2D laser cutters are cut in two dimensions, the x-axis and y-axis. 3D laser cutters cut in one more axis, the z-axis.

The work principle of 3D laser cutters is the same as any other laser cutter. There’s a light source that requires power to generate laser light. Focusing optics amplifies the light, and the laser head applies the light to the workpiece.

As 3D laser cutters can cut vertically, a robotic arm controls it, unlike 2D laser cutters that work in a gantry system. You can cut three-dimensional objects, give them your desired shape, and make necessary parts using 3D laser cutters. Here is a video of a 3D laser cutter in operation:

Application Of 3D Laser Cutting

The same industries that use 2D laser cutting are starting to use 3D laser cutting due to its versatility and efficiency over 2D laser cutters. Here are the sectors that are utilizing this fantastic piece of modern technology:

Ruimtevaart

Aerospace is one of the most complex sectors. It uses highly sophisticated machinery consisting of complex parts. Most machine parts are three-dimensional, which is required for 3D laser cutting.

For any cutting or engraving required in such intricate parts, 3D laser cutters can easily do this. 3D laser cutters can aid in manufacturing various parts such as aircraft frames, intricate engine components, and turbine blades. Also, 3D laser cutters can work with aluminum, composite materials, titanium, etc.

Automobile

The automobile sector is expanding every day. People are using more cars than ever nowadays. Advancements in this sector are in front of our eyes. Electric vehicles, hybrid vehicles, voice-operated smart vehicles, etc., are this sector’s latest inventions.

Modern vehicles contain various parts, such as complex transmission systems, catalytic converters, and turbochargers. The reason behind such advancements is the ease of production. One of the many contributors is 3D laser cutting.

3D laser cutters can cut the required shape quickly and accurately to produce chassis parts, body panels, exhaust systems, seatbelts, airbags, and other safety features.

Architecture

Architecture is all about creativity and precision. There was a time when architects had to make large, complex models by hand using wooden blocks, polystyrene, foam, cardboard, etc. But now is the age of computers.

Architects can now use CAD/CAM software to make their desired model and 3D print it in minutes. They also use 3D laser cutters to cut the 3D model where necessary. As we have already said above, architecture is all about precision. No other cutting tool can be as precise as a state-of-the-art 3D laser cutter.

Arts And Sculpture

Arts and sculptures are complex, three-dimensional things. There is nothing two-dimensional about it. So, even two-dimensional CNC laser cutters were not helpful to this sector. However, things have drastically changed with the invention of the 3D laser cutter.

Sculpture artists have benefitted more than ever with the invention of 3D laser cutters. They can now make detailed artworks and sculptures using different materials such as wood, acrylic, metal, etc.

Benefits Of 3D Laser Cutting

3D laser cutters have lots of benefits. That’s why many sectors are leaning towards it. Here are some benefits of 3D laser cutting:

Ability To Create Complex Geometries

3D laser cutters can cut in three dimensions. So, it can easily cut any 3D object where you need it to and produce the necessary shapes.

No matter how complex the cut is, 3D laser cutters can easily get the job done. Various complex 3D shapes and contours are challenging or seemingly impossible to achieve with other cutting methods. 3D laser cutters can be the savior here.

Automation And Integration

3D laser cutting systems are fully computerized, just like 2D laser cutters, 3D printers, etc.; very little human intervention is required to complete a process using a 3D laser cutter.

You can integrate 3D laser cutters with computer-aided design and computer-aided manufacturing (CAD/CAM) software. It will enable automated and computer-controlled cutting, reduce labor costs, and minimize the possibility of human error.

Precision, Versatile And Fast

3D laser cutting systems are very precise, which makes them suitable for complex designs. They can cut with tolerances within millimeters and produce consistent results.

It is especially valuable in industries where accuracy is critical, such as aerospace and medical device manufacturing. Besides that, 3D laser cutting systems are versatile and fast. They can work with metals, plastics, ceramics, and composites. 

Considerations Of 3D Laser Cutting

Before investing in any new technology, certain considerations must be taken. And it’s the same for 3D laser cutting.  Here are some things to consider about 3D laser cutters: 

Expensive

3D laser cutters are costly. The starting price of a 3D laser cutter is around $18000 to $20000, which is very steep.

So these advanced machines aren’t beginner-friendly in terms of price. Maintenance cost is also high; any repair or parts replacement will cost you a hefty amount.

Very Complex

As we have already said above, 3D laser cutters are complex. They have more parts than 2D laser cutters. These parts are complex, and the assembly is also pretty complicated.

The complexity makes 3D laser cutters somewhat difficult to operate and master. Repairing and maintenance also require an expert hand.

Requires Skilled Operator

Regarding ease of operation, 3D laser cutters are not beginner-friendly either. You can buy and start using a 2D laser cutter with little to no help from experts.

3D laser cutters are different. Before using one, you will need to learn many things about 3D laser cutters. If you don’t have the time, you’ll have to hire expert help, which will be costly.
