A natural phenomenon in the industry of materials for 3D printing is the constant pursuit to create more and more useful filaments, surprising with properties. Consumables manufacturers are competing to provide customers with materials that are durable, resistant to mechanical damage, thermally resistant and distinctive in appearance. To extremely interesting proposals belong silk filaments, which are a combination of two other well-known materials: PLA and PETG and recognizable at first glance thanks to their glossy, satin surface.
Silk - impressive filament for 3D printers
In Botland shop you can find silk felt supplied by well-known Polish brand Devil Design. The material is available in an impressive range of colors, including as many as ten colors and shades: from white, light yellow, light orange, light pink, red, through blue, purple, light green, to gold and brown. Filaments are wound on spools with a net weight of 1 kg, and the bundle diameter is a standard 1.75 mm. What's important, DevilDesign silk filament is compatible with almost all devices on the market working in FFF technology. Before using it you just need to make sure that the manufacturer does not limit the range of materials used in 3D printer (in some cases, suppliers of printers stipulate to use only materials of their production to work with models).
Printing parameters with silk felt
During the production of models with the use of the discussed felt, the temperature of the nozzle should be set in the range of 225-245 ° C, while the work table is sufficient to heat up to 50-60 ° C. For users who work in Cura environment, we recommend ready profiles for 3D printers, available for download from Botland - they significantly speed up the preparation of the device to work. During the production of models with silk felts, you can turn on the option to cool the printout, although it is not necessary. However, the manufacturer points out that these felts for 3D printers can rapidly increase their volume (swell) when squeezing from the nozzle. This phenomenon is due to the natural surface tension formed in the polymer material, but to minimize the impact of "swelling" of the filament on the printing process, you can slightly strengthen the cooling. An additional way to achieve the expected results is to print at a lower speed - this principle also applies to many other felts.
The prototypes of silk, namely PLA and PETG
The basis for silk materials is the popular PLA filament. It's one of the most popular 3D printing materials, suitable even for complete beginners in FFF/FDM technology. The most important advantages of PLA include non-toxicity and odourlessness, as well as low requirements for printing conditions - especially a relatively low melting point, thanks to which it can be used in almost any 3D printer. PLA filament is also characterized by high stiffness, so you should not plan to make models from it for processing such as drilling, because it could crack. The second component of silk material is PETG filament. It is a popular PET material (known even from the bottles for beverages), enriched with a admixture of glycol. The biggest advantages of using PETG include non-toxicity and odorlessness and a small tendency to shrink during cooling. Natural PETG filament is transparent and its surface - slightly glossy.
