All users of filament-based 3D printers (FDM/FFF) are well aware of the properties and capabilities of PLA plastic. It can’t be otherwise, because absolutely all filament printers available on the global market and in Ukraine work with this material. What is the secret of this plastic’s popularity?
The main advantages of PLA plastic:
PLA plastic is a polylactide, which is a thermoplastic aliphatic polyester by its chemical composition. The raw materials for its production can be corn, sugar cane, corn and potato starch, soy protein, cassava tubers, or cellulose. Due to the naturalness of PLA plastic’s natural components, it can be used without endangering human health. Carbon dioxide emissions during the production of this material are significantly lower compared to the production of «petroleum» polymers, such as ABS plastic for 3D printing. The use of fossil fuels is also one-third less, and solvents are not required at all.
Typically, PLA plastic comes in the form of a thin filament on a spool. XYZprinting produces filament for 3D printers with a thickness of 1.75 mm and offers users 15 colors of this plastic to choose from. This provides a lot of room for imagination and creates ample opportunities for making a variety of products.
XYZprinting is a global leader in 3D printers production. The company cares about the users of its products, so a few years ago it launched the safest version of plastic on the market – Antibacterial PLA.
This filament contains silver ions that inhibit bacterial growth by more than 99% and reduce the risk of infection. Such an antibacterial agent is authorized by the RoHS directive adopted by the European Union to limit the content of harmful substances in electrical and electronic equipment.
You can create safe, functional items for friends and family: personalized ceramics, kitchenware, bathroom accessories, and more. Thanks to its enhanced protection against germs and infections, Antibacterial PLA is a safe and hygienic material for teaching children the basics of 3D printing.
Products made of PLA plastic are sanded, drilled, and painted with acrylic. It is worth remembering that items made of this material should be handled with great care due to its fragility. PLA plastic is not a very durable material; products made of it will last from several months to several years. It is an excellent solution for 3D printing prototypes and products that will not be used for a long time, such as decorative objects, presentation elements, and objects with fine detail.

For many years, PLA plastic was inferior in strength to another popular plastic – ABS, but today XYZprinting is ready to offer users Tough PLA. This is the same natural safe product, but stronger and more resistant to mechanical stress than ABS. It can be used to produce reliable tools, accessories, and parts.
This PLA plastic has excellent stiffness and resistance to tensile deformation. It has been rigorously tested in the SGS laboratory, where it was confirmed that the material does not contain substances harmful to humans, including dioctyl phthalates and heavy metals.
Tough PLA is available in black and white.
Another type of XYZprinting PLA plastic is 3D Color-inkjet PLA. This filament was created specifically for the da Vinci Color full-color 3D printers series. Initially, it has no color, but in the process it is painted in any color with the help of special inks supplied to the print zone from the installed CMYK cartridges.
Printing with 3D Color-inkjet PLA is absolutely safe for humans and the environment. These filaments are RoHS compliant and made from environmentally friendly and recyclable material.
Premium Metallic PLA is the most unusual type of plastic in the XYZprinting range. It is made from a mixture of polyacrylic acid and copper powder, which allows you to produce 3D models with a unique shiny surface. It is the best option for creating things that look and feel like metal: figurines, copies of art objects, jewelry, etc. A simple finishing treatment will give these products a glossy shine that will not fade over time. All you need is sandpaper, steel wool, and polish for metal surfaces.
3D printers for working with such plastic should be equipped with special XYZprinting nozzles made of heavy-duty steel, which can be purchased separately if necessary.
In conclusion, it is worth noting once again that PLA plastic is safe for humans. It can be used for industrial tasks, as well as for household needs and education. And XYZprinting, the world’s leading 3D printer manufacturer, has already provided a wide range of materials for users to use, so they don’t have to limit their imagination.
