Airwolf3D, a well-known 3D printer, recently tested a new biodegradable material, bioFilaLinen, which was produced by twoBEars, a German company. As we all know, our most common biodegradable 3D printing material is PLA. But unlike PLA based materials, bioFila does not contain hemp fibers. Instead, bioFila provides strength and stiffness through wood, known as lignin, an organic component found extensively in plant cell walls and paper. When the 3D is printed, the texture of the bioFila looks a bit like a bedspread, and when the print temperature is above 205 degrees, it can produce a much more porous structure that looks coarser.
In 3D print test, Airwolf uses the AstroPrint operating system according to the default settings for Laywoo-D3 materials (hot end of 220 C and 70 C, the first printed bed layer of 0.4 mm), which belongs to the set bioFila recommended the setting range of high-end. The material is printed accurately and smoothly, indicating that it is highly adaptable to changes in print temperature. The result is interesting: eventually, the printed product has a visual texture similar to that of a linen lampshade, and resembles the traditional PLA in stiffness. Also, the 3D object printed with bioFila seems to have better impact resistance than PLA, but the tensile strength of PLA is better. The following is a performance comparison of bioFila, PLA, and ABS listed by Airwolf.
According to twoBEars, bioFila is made of natural organic materials, biodegradable, non-toxic, recyclable, and food safety. The use of bioFila is also very convenient and can be used by educational institutions, and the unique aesthetic characteristics of this material are sure to catch the artist's eye. However, do further research for the durability of the material to be. The biodegradable wire is durable as long as it does not expose itself to the natural environment for long periods of time, according to twoBEars officials.
"If you put 3D printed objects in an apartment, it won't change," explains BennoBesler, founder of TwoBEars. But if you throw it into nature, they fade away like wood."
In addition, twoBEars confirmed that if you decide to throw your bioFila3D print outside, it won't decompose harmful chemicals into the environment like some other wires. Overall, this seems to be a totally environmentally sound material. Enthusiastic environmental protection 3D print enthusiasts can pay attention to.
