What is 3D printing?

3D printing is a process of making three dimensional solid objects from a digital file.

  1. It all begins with the creation of a 3D model on your computer. There are many 3D modelling softwares you can use. We advise using Simplify 3D and also deliver a free copy of this program when you buy a Tractus3D printer.
  2. When you have a 3D model, the next step in the 3D printing process is to prepare it in order to make it 3D printable. This process is called slicing which means dividing a 3D model into hundreds or thousands of horizontal layers. This is all done automatically with Simplify3D so you don’t need any additional slicing software.
  3. When your 3D model is sliced, you are ready to feed it to your 3D printer. When the file is uploaded to a 3D printer, the object is ready to be 3D printed.
  4. The object will be created by laying down successive layers of material. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.

3D printer comparion – how to compare?

When you are wondering about 'what is 3D printing' you might consider investing in an industrial 3D printer, of course, they want to do a 3D printer comparison. 3D printers come with a wide range of features and different specifications, which means that the 3D printer price can vary hugely. The big difference often comes down to the specific construction parameters of both devices.

What is the difference between 3D printers? Where is it based upon and how to do a 3D printer comparison? When you are looking for the best solution for your business, it is worth understanding a little more about 3D printers. We summed up the main criteria to consider when comparing 3D printers.


Industrial 3D printer price – where is it based on and how to calculate your ROI?

When wanting to learn more about 'what is 3d printing' you must understand a big difference. While much attention has been focused on the consumer market, consumer-grade 3D printers are not suitable for large-scale production grade additive manufacturing. Industrial 3D printers are designed for a specific purpose and they have the speed, facilities and robustness which are critical for industrial 3D manufacturing.

They come with a wide range of features and different specifications, that means that the industrial 3D printer price can vary hugely. To identify just how much industrial printers cost and how to calculate your ROI, it is worth understanding a little more about them.

3D printer resolution – what does it really mean?

When you want to know more about what is 3D printing, you need to learn about the 3D printer resolution. Because the 3D printing process is such an accurate procedure, the resolution is in the size of microns. A micron is one thousandth of a millimeter, so it is extremely small. By displaying the 3D printer resolution, the buyer has a general idea of what the printer is capable of. There is more to the story, however.

It’s important to know that there are three types of possible deviations in the 3D printing process: machine-, material- and end result deviation.

3D printing technology – Delta vs Cartesian

The 3D printing market is quite competitive, so there are plenty of different printers to choose from. Each printer has its own 3D printing technology and unique capabilities, so it’s important to know which printer is most suited for the results you want to achieve. As most 3D printers, Tractus3D printers use the FFF method (also known as FDM printing), which means everything is printed layer by layer using filament.

In the FDM 3D printing technology, two types of printing systems can be distinguished: Cartesian and Delta. The biggest difference between these two systems is the method of moving. Because each system has its own way of moving, you can achieve different results.

The advantages of 3D printing

When you want to know more about what is 3d printing, you sure also want to know more about the benefits of this relatively new technology. Through creating layers, 3D printing opens a whole new way in which products are created and it offers a lot of advantages compared to the usual traditional manufacturing methods. They will be used to deal with a wide range of tasks in the same way that the digital revolution of twenty years ago enhanced lives and businesses in ways that could never be imagined.

There are many different types of 3D printing technologies available but the advantages discussed here are applicable to the whole industry. Through fast design, high levels of accuracy and the ability to make informed decisions, the following advantages make 3D printing a real prospect for businesses but also highlight its importance in future production techniques.

What is FDM 3D printing?

To the question 'What is 3D printing?" there is not one absolute answer. The way in which 3D printing has developed in recent years is nothing short of astounding with a wide range of 3D printing technologies available.

The most common is the Fused Deposition Modelling, also known as FDM. This is a technology that has been patented by Stratasys and it is a technology that enables the creation of prototypes in a very short timeframe. This technology is also known as Fused Filament Fabrication or FFF. All Tractus3D industrial printers make use of this technology. Many different industries choose to use FDM 3D printing including the automotive industry and a wide range of consumer goods manufacturers. They use FDM because it helps to aid their product development, their prototyping and their manufacturing process.

Thermoplastics as a substitute for metal additive manufacturing?

Metal additive manufacturing technology enables the production of highly complex geometries due to the fact that is not constrained by the same rules associated with subtractive machining and other traditional manufacturing techniques. In fact, some 3D printed parts are already just as good, if not better. But there are more benefits. In this article we will first have a look at the other advantages that this relatively new technology brings. Then we will explain why 3D printing thermoplastics can be an even better and cheaper substitute. More and more companies are using 3D printing thermoplastics for crafting metal (like) objects as this has a lot of extra advantages compared to the standard process of metal additive manufacturing.

3D printing in manufacturing

The manufacturing industry is always looking at new and innovative ways of working and in recent years, 3D printing has been at the forefront. Advancements in the 3D printing technology, equipment and materials has resulted in the costs being driven down and that makes it a more feasible option when it comes to general manufacturing use.

Traditional manufacturing has to deal with the ever-growing demands of the world but it has some restrictions. That is where 3D printing can step in to take over. 3D printing for manufacturing comes with a number of exciting and unique advantages when compared with traditional manufacturing.
