3D Printers and Accessories
(699)Using 3D printers opens up a wide range of possibilities for individuals as well as industrial users. Regardless of application, filaments are necessary for using 3D printers.
Below, we have described some of the most popular filaments available from us and have summed up their properties, requirements, and characteristics.
PLA – the basic filament for 3D printing
In the consumer 3D printing industry, polylactic acid (PLA) is most often used. PLA is certainly the most popular type of filament for 3D printers for a reason.
PLA properties
PLA is a very easy-to-use material. The printing temperature is lower than in other materials (180 – 230°C). Moreover, PLA does not warp during the printing process, so a heated bed is not required. A big advantage is the range of colours available and the absence of an unpleasant smell while printing. PLA is often used as a base material for working with more specialised filaments that, for example, have conductive qualities. It is also worth mentioning that it is a biodegradable material.
Disadvantages of using PLA
Of course, PLA has its disadvantages, too. Most importantly, it is an easily breakable material, which is why it is not good for making objects that can be subjected to bending, twisting or hitting. Additionally, PLA can get deformed in temperatures over 60°C.
Advantages and disadvantages of using ABS
The second most popular filament is ABS – acrylonitrile butadiene styrene. In terms of its properties, ABS is moderately better than PLA, even though it is harder to print (it is prone to warping without a heated bed and gluing to the print bed). The printing temperature ranges from 210°C to 250°C. Another disadvantage are the dangerous fumes which are emitted during the printing process. That is why the room where the printing takes place should be well ventilated. Often used in the injection moulding, ABS is part of many home appliances and consumer products made of plastic, including LEGO bricks and bike helmets. Thanks to its resistance to bending, hitting and high temperatures, it is also used when making cases for various devices, handles or other finishing elements; however, it is not suitable for, for example, items that have contact with food.
What is TPE? What are the advantages of TPE?
As the name suggests, thermoplastic elastomers (TPE) are basically plastic products with rubber-like properties, thanks to which they are remarkably flexible and durable. TPE is mostly used in the production of car parts, home appliances and medical products.
It is worth noting that this is not one type of material, but a wide class of copolymers (and mixes of polymers). Their soft and flexible fibres are resistant to strain, unlike ABS or PLA. However, printing it is not always easy, because TPE may be hard to emboss.
Thermoplastic polyurethane (TPU) is a special kind of TPE and is a popular filament for 3D printers. Compared to the normal TPE, TPU is slightly more rigid, which makes printing easier. It is also slightly more durable and keeps remains more flexible under colder temperatures compared to TPE. Both TPE and TPU are a rather demanding filaments when it comes to printing – they require a thin path for and a low speed of printing in the temperature range between 210 – 230°C.
Thermoplastic copolyester (TPC) is another variety of TPE, however it is not as widely used as TPU. The main advantage of TPC is its high resistance to chemicals and UV rays, and heat (up to 150°C).
Filaments for industrial use
The remaining filaments available from us are used for industry. An example is the iglidur® filament – a series made from highly efficient base polymers (with a mix of different kinds of fibres and solid lubricants), which ensure preferable properties of the materials required for different applications. Certain components ensure the necessary durability and resistance, and limit the wear and tear of printed elements. Thanks to this, they are perfect for making, for example, bearings.
