9 benefits of having an industrial 3D printer with a system of interchangeable printing module

The modular construction of industrial machinery

Manufacturers of machinery used in various industries have been focusing their attention on the production of modular construction machines for many years. As a user, we get a machine in a basic configuration, and then, depending on our application and needs, we expand the purchased device with dedicated modules or tools specialized for a specific range of work.

For example, the selection of an appropriate tool used in a CNC machine allows for optimal use of its capabilities and adaptation to our application. The modular construction of the 3D printer is based on similar assumptions.

Modular solutions are increasingly used by machine manufacturers because they are much more practical and, what is more, they are in line with the idea of Industry 4.0. The user can have a machine that is flexible enough to adapt to changing expectations and different applications. The ability to upgrade the machine during its life cycle and the quick installation of other accessories such as specialized tools or modules is a great added value for any industrial class machine.

The use 3D printer in the industry & 3D printing materials

Manufacturing companies all over the world are increasingly equipping their machine parks with industrial 3D printers. For instance, 3D printing technology is being used to produce railway equipment, aircraft manufacturers replace metal components with materials like PEEK, ULTEM, PC or PEKK-CF that are lighter yet resistant for various environmental factors. What’s more, the automotive industry makes numerous prototypes much faster and produces the jigs & fixtures using additive manufacturing.

The range of engineering and high-performance 3D printing materials available on the market is very wide and is still being developed. Work with filaments resistant to high temperatures and chemicals with extraordinary mechanical properties opens up opportunities for new applications in many industries. Engineers from various departments, including R&D, want to be able to work with the full range of available filaments using one 3D printer. Unfortunately, this is not always possible, because additive manufacturing machines have some limitations that reduce the scope of their work, for example, materials available for use.

Why industrial 3D printer should be equipped with the modular system?

What are the must-have features for a 3D printer capable of producing parts from high-temperature materials such as PEEK, ULTEM, or PC to reinforced or flexible filaments? Find out more about why the industrial 3D printer should have a modular system.

1. Why most 3D printers can’t print from several different groups of materials?

There are many 3D printers on the market today, which work with a very narrow range of materials. It is associated with the need to have several different devices, each one for different applications. Such a situation results in increased purchase costs of a machine. Moreover, customer resources are used inefficiently. How does it look in practice?

piramida

To 3D print a part with ABS, a low extrusion temperature material from a group of basic polymers used in 3D printing (the so-called Commodity), we need to use one 3D printer. When we want to produce parts with carbon fiber reinforced materials such as PA-CF or PC-CF, we need a second 3D printer, usually much more expensive. On the other hand, if we want to print models from a group of high-performance materials with high mechanical properties that will be resistant to high temperatures and chemicals, we have to equip our machinery park with another 3D printer. There are few devices on the market that work with such filaments as PEEK, PEKK, or ULTEM. Printing with these materials requires specific temperatures and conditions e.g. actively heated chamber.

The 3D printing process must be adapted to the specific material, and one of the main parameters of this process is the extrusion temperature of the material, which is directly related to material thermal parameters like glass transition temperature or softening temperature. For example, PEEK requires the hotend to be heated between 360°C and 400°C to be extruded in the 3D printing process, while ABS needs only around 230°C to 260°C. Every standard 3D printer will have the problem to extrude so vastly different materials on one hotend. 

The 3D printer’s modular construction allows you to purchase a single machine, which will allow you to print from multiple materials from different groups and receive models of very high quality. 

Even when using the device most of the time to print basic materials such as ABS or PLA, you may need to 3D print parts from more durable materials such as PEEK or carbon/glass fiber reinforced materials. In case of a modular 3D printer, there is no need to purchase another device. Thanks to that solution you can upgrade your current machine and add other printing modules customized to a specific group of materials to optimize the printing process. The cost of purchasing the module is often many times lower than buying another 3D printer. Each module is customized to a specific group of materials in order to optimize the printing process.

2. Why can't you print different groups of materials using the same hotend?

Each change of extruded material to the other one with different properties may cause the clog of a printing nozzle. If we made a print using PEEK material and immediately afterward trying to print from PLA (the extrusion temperature of this material is much lower in comparison to PEEK), the remains of PEEK material would make printing with PLA impossible. On the other hand, trying to print material with low extrusion temperature at higher temperatures will lead to its degradation. As a result, the mechanical properties of the material and its resistance to external factors may be significantly reduced or lost. A great convenience for the user is the possibility to purchase a 3D printer equipped with a modular system that solves this problem.

Interchangeable printing modules - description and advantages

The system of interchangeable printing modules allows the use of a wide range of materials on one machine. From commodity materials, which are widely used in the industry for rapid prototyping, to engineering and high-performance filaments for custom applications.

Modular system in practice

The construction of each module is dedicated to a specific group of materials and its characteristics to optimize the 3D printing process as much as possible. To obtain the best print quality and details it is necessary to adapt the printing process to the specific material. Each part should be printed from material with properties that are appropriate for its working environment (e. g. high chemical or mechanical resistance).

Let's look at the 3D printer as a machine and the module as a tool. The more tools we have, the more functional our machine is. We use only one tool at a time, so there isn't a problem to replace the tool for another, which will bring us the expected result. It is exactly the same in the case of 3D printers. Each module is a tool to work with different groups of filaments, often with extremely different extrusion temperatures.

6. Autocalibration

This feature makes it easier for users to work with the machine. Each module is equipped with an integrated tensometric system responsible for autocalibration measurements. Thanks to the automatic calibration system, even the slightest curvature or deflection of the heatbed from the level are continuously compensated by the 3D printer during the printing process. What’s more, each module is also equipped with EEPROM memory. The offset calibration values for this module are saved in the memory. Thanks to that these values do not have to be additionally measured and saved after module replacement, which allows for the quick start of work with the machine.

7. Practical solution adjusted to selected applications

You can upgrade your 3D printer and add chosen modules designed for printing with other materials you need.  The purchase of other modules may be postponed.

8. 3D printing complex parts

Each module is equipped with two hotends, which enables printing with model and support material (soluble or breakaway). The complete mechanism, thanks to its driving servomechanism, is able to automatically switch the printer between one of the two materials in less than 1 second.

9. No warping

The modules contain the active print cooling system, which is the basic method of preventing the warping phenomenon – the curling of the print corners up. In extreme cases, it may lead to major printing failure and always adversely affects the appearance, especially the bottom of the print surface.

3DGence’s R&D department is systematically developing new solutions, which is related to the constant expansion of machine capabilities. This allows each customer to update their 3D printer during use. Machine development is carried out also in the field of 3D printer software and its components. .

One year after the premiere of the 3DGence INDUSTRY F340 printer, the R&D department developed a new printing module - the HF printing module. The new accessory is characterized by the possibility of printing from reinforced materials such as PA-CF and PA6-GF30. This module also allows for faster printing from some commodity materials.
