3D printing, otherwise known as 3D printing, involves creating three-dimensional objects. It is increasingly being used in various areas of life and is growing in popularity. What exactly does it consist of?

How does 3D printing work?

The basis of this method is a three-dimensional computer project. You can create it in special programs or use a 3D scanner, which will scan the thing you want to print. The digital file instructs the printer on how to build the object. It does this by dividing it into layers and describing the dimensions of each layer. Special printers create objects using a variety of materials, such as light-cured resin, nylon or ABS. There are many 3D printing processes, but the most commonly used method uses a powdered base material.

Some 3D printing techniques are designed to create smaller and simpler details, others for very precise and some for very durable items.

Advantages of 3D printing

This method of printing was created as an alternative way to make prototypes. Some of the major advantages of this type of printing include:

– quick time to make models

– low cost of producing them

– high profitability of creating single copies

– the possibility of rapid application of various changes

– possibility of personalization

– ability to print complex geometries, which would not be possible to perform using other methods.

3D printers

Ready digital file should be uploaded to the 3D printer. It copies every layer which is described in such a file. Printers must be very carefully calibrated to properly print the object. The highest quality equipment is offered by Botland, for example.

Types of 3D printing technology

There are different types of 3D printing. They can be divided into several categories, while the main differences between them lie in the way individual layers are deposited. The most popular methods use melting of materials. The most popular method of this type is FDM, which involves creating an object from molten filament that hardens to form layers. Other methods harden liquid materials, while some use powder.

3D printing can also be divided based on accuracy, material, or speed of making parts. In addition to methods, available materials and printer size are also important. Different types of printers can be used to create, among other things, finished products, those that require post-processing, prototypes or components for other items.

What is printed with 3D printing?

Currently, almost every industry uses 3D printing. This is because this printing used for mass production is cheaper than other methods. With the help of 3D printers, you can primarily create customized models. As mentioned above, we have the ability to personalize the printed item. You can customize the design according to your individual needs. For example, some companies produce shoes on demand. In this case, size and shape are no limits.

3D printing also allows prototyping. This is very helpful especially for engineers and designers, who can thus visualize the product and get feedback on it in a short time.

If someone cares about mass production, 3D printing will definitely also be a good way. Modern printers are equipped with WI-Fi network, so you can connect them into one network. They will then print the same parts in larger quantities. Each 3D printer can also print smaller pieces of some larger project, which will then be connected together.
