Laser 3D Printer vs 3D Printer: Know the Differences

There are many manufacturing processes used around the world. Among all, laser cutting and 3D printing are two of the most used manufacturing methods businesses rely on.

3D laser printer and 3D printer might sound similar, but there is a huge difference between both.

Based on different technologies, these devices perform the same task in unique fashion to produce different quality parts.

The major difference lies in the terms itself. While laser cutting is based on subtractive manufacturing, 3D printings is based on additive manufacturing.

Both are completely different in terms of their working and so are the end parts. To decide which manufacturing technology will better serve your business process, let us gather some brief idea about both the options available.

3D Laser Printer and 3D Printer

A 3D laser printer is based on laser cutting, a technology also known as subtractive process.

In this process, the material is cut with the help of 3D or tube laser to shape the object as per the 2D design.

Because of the extreme accuracy of these lasers, one can manufacture intricate and precise designs with its use. Moreover, the material available for laser cutting process is also huge.

One can use fabrics, composite materials, wood and even metal with laser cutting technology.

With all the benefits it has, it does require post processing steps such as welding to finish the parts.

Either its prototypes or any other finished product, one must include the hectic post processing methods to get the desired object.

On the contrary, 3D printing involves adding layers of materials one over another and joining them with different processes to get the finish part.

It is more of an additive process which makes it completely dissimilar to laser cutting process.

To build a 3D part, one needs the printable 2D model of the object. Once fed to the 3D printer, the machine progresses to build the final object.

Unlike 3D laser printers which cut the material, 3D printers join layers together.

More About 3D Printing

3D printing is much deeper and has steep learning curve than you would have known so far.

This is the fastest growing technology and is being used for various applications. Within 3D printing, there are many processes involved.

Materials are also used in different forms to be used with different process based 3D printing machines.

Depending on the characteristic of your project, the budget, quality of object and what you want to print decide which additive manufacturing process would be better than the others.

Your specific need is the best parameter to judge which 3D printing process would be your mate.

You can 3D print with Plastics using technologies such as Fused Deposition Modelling, Selective Laser Sintering or Multi Jet Fusion.

To 3D print with resins you can go with SLA, CLIP technology or Polyjet. Metals printing is also possible with Selective Laser Melting, Direct Metal Laser Sintering, and Binder Jetting.

There are other materials also which could be printed using these technologies such as alloys, ceramics and lot others.

The 3D Printing is highly recommended for diverse projects when one need precision and quality together.

Here are few examples of 3D printing processes:

fdm, sla, sls processes

#1 FDM:

Fused deposition modelling uses a heated nozzle to melt the filament material and deposit it layer by layer on the build platform. Each time the layer is deposited, it solidifies while the other layer is prepared to be deposited over the prior one. This way, entire part is printed.

#2 SLS:

Selective laser sintering is the process of fusing powdered material to form solid parts. Laser beam is used to melt and fuse the material together.

The powder is deposited one layer at a time. After each layer solidifies, another layer is deposited. Finally, the part is 3D printed.

Later, during post processing, the unused powder is removed using brush or compressed air.

#3 SLA:

Stereolithography, abbreviated as SLA uses resin as the material. The photosensitive resin is cured by photopolymerization one layer at a time.

Once the layer solidifies, another layer is formed. This happens until the entire part is printed.

There are many other processes in 3D printing. Based on one’s need, one can choose the 3D printing process.

3D printing is widely used among various niches. For example, fashion industry, aerospace, food industry, medical industry etc.
