Filament for 3D printers is produced by free extrusion. This is one of the most difficult processing techniques by extrusion, due to the particularly large impact of process parameters on the dimensions of the product. Due to the high quality requirements for the product, which is the filament for 3D printers, when introducing a new material into production, the selection of processing parameters is made using the experimental method. The introduction of any changes to the material recipe and processing conditions (process and ambient temperatures, raw material drying efficiency, line configuration) will affect the quality of the extruded filament.

Lines for the production of fibers (filaments) with a fi 45 mm extruder, which are intended for use in 3D printers, are characterized by high linear speeds, precision and dimensional accuracy, energy efficiency and intuitive operation while maintaining large control possibilities of the entire process.

The filament production line equipped with a 45 mm extruder with a capacity of 40-60 kg / h is known for the production of filaments with high efficiency. Thanks to the high performance of the filament extruder, filaments with a diameter of 2.85 mm and other profiles with a larger diameter or cross-section can be efficiently produced. In order to use the possibilities of such a line, it is necessary to use efficient cooling of filaments and profiles with a larger diameter.

In order to produce a filament, you need to use a plastic in the form of granules, melt and plasticize it, form a continuous filament from the melted plastic, and then on a spool. It may seem easy, but a good filament that actually prints well must be completely uniform and homogeneous in terms of composition. The key parameters determining the quality of the filament for 3D printers are its diameter and ovality. Changing the diameter or ovality by a few hundredths of a millimeter can result in poor print quality. The extremely fast-growing 3D printing industry challenges manufacturers of filament production lines and plastics producers. The 3D printing process introduces a new level of variability. Modern customers using 3D printing technology do not like to wait long for new filaments and prefer to quickly admire new ideas and inventions. This is a problem for larger industrial manufacturers with their long product development cycles and inability to produce customized products.

For the above reasons, the filament production line must be built with devices with high technical parameters. It is important to be able to precisely and at the same time repeatably set [adjust] all device parameters; such as temperatures [extruder, water in tubs, pressure, extruder speed, material pump, extraction].

Our line produces high precision filament. The repeatability of the filament diameter dimension, while maintaining proper ovality in the xy axes, cannot be worse than +/- 0.05 mm. Filament recipients often expect higher precision of +/- 0.02-0.03 mm, our line allows to obtain such parameters. The line can also produce other filaments, filaments, tubes and plastic welding wires. The plasticizing system can be adapted to process the required polymeric materials. We offer screws with optimal configuration for various polymers. The line is adapted to the production of filaments with diameters of 1.75 mm, 2.85 mm, 3.00 mm. It is possible to produce other diameters of lines.

The line is built of many devices, all devices form a whole and are digitally controlled via a communication bus connecting them. The operator communicates with the line through three touch screens, including one with a large diagonal, which allows you to control the entire line. In addition, the control and data recording systems can be adapted to customer requirements.

Technical description

Requirements for lines for the production of filament used in 3D printing.

Since filaments for 3D printers working with the use of FDM technology are subject to very high requirements regarding uniformity, diameter and ovality, the lines used for their production must also meet high requirements:

The technical and operational requirements for the line for the production of filament for 3D printers are not small, therefore the software that allows you to manage all devices working in the line should provide:
