BIODEGRADABLE FILAMENT - THE FUTURE OF 3D PRINTING

09.08.2019

Filament - a thermoplastic material used in the 3D printing process, so far it has been mostly produced only from non-biodegradable materials.

Elements printed from this type of filaments, if not recycled, have an extremely harmful effect on the environment. The destructive effect on the ecosystem is also the emission of toxic fumes, in case of the improper thermal treatment during printing, which may cause irritation to the eyes and respiratory system.

The two most common filaments used for 3D printing are ABS and PLA. ABS is a thermoplastic material that is ideal for 3D printing due to its strength and durability.

However, this material is not biodegradable, but it can be recycled. PLA material, which is made from vegetable starch, undergoes biodegradation under certain conditions. Certainly the bioplastic, which is a mixture of PLA with plant waste, is a much better alternative in terms of ease of degradation in the environment, compared to pure PLA. What is more, it creates a material with a number of new properties and applications.

The innovative character of bioplastics increases their attractiveness and competitiveness on the plastics market. Due to the growing awareness of consumers about the negative impact of plastic on Earth, the demand for ecological and environmentally friendly materials is growing in various industries, which are a great replacement for existing products made of conventional plastics.

It is no wonder that more and more biofilament producers on the world market are choosing biodegradable organic raw materials such as waste from plantations of tomatoes, olives, coffee, hemp, soy and wood fiber, cork and even seaweed. Filament produced from biological materials, thanks to non-toxicity, can be used to print 3D objects that have subsequent contact with food.

To process plant raw materials for biofilament, you must have the appropriate set of equipment for granulation and for the production of filament for 3D printing.

Due to that fact ZAMAK MERCATOR created a modern filament production line with a diameter from 1.75 mm to 3.00 mm with very high dimensional accuracy, which allows easy processing of bioplastics into an environmentally friendly plant biofilament.

What is important in the production of this type of filament, all elements of the production line are characterized by extraordinary strength and durability of components. Low energy consumption, thanks to the efficient and economical zone heating and cooling system, helps reduce production costs, and the thermoregulators used in all ZAMAK MERCATOR extruders have very good technical parameters and are easy to use.

Heaters and cooling system are simultaneously controlled by a digital PID controller. This solution allows maintaining the set temperature with high accuracy around 1 oC and avoids the so-called overdriving, i.e. uncontrolled increases or decreases in temperature that may have a significant impact on the quality of the biofilament. The whole line is a set of compatible machines designed and manufactured entirely in Poland by ZAMAK MERCATOR.

They are characterized by high linear speed of operation, precision, as well as intuitive operation, while maintaining control over the process.

Due to the strict quality standards of filaments for 3D printers, when introducing a revolutionary material used in processing, which is biofilament, to market, it is necessary to use equipment that you can rely on - this is exactly the filament production line created by ZAMAK MERCATOR.
