Fillamentum provides 4 new colours to ASA Extrafill filament vary

The Czech 3D printing filament manufacturer Fillamentum has added four new colors to its ASA Extrafill filament range.

Three of the new additions are inspired by the upcoming spring season namely “Dijon Mustard”, “Vivid Pink” and “Snow White”, while the company’s popular “Vertigo Gray” color option has been expanded against the backdrop of ASAon Filamentum’s seventh birthday.

The company’s ASA Extrafill filament is now available in a total of 14 color options.

ASA Extrafill filament from Filamentum

Developed as an alternative to ABS, ASA is a styrene polymer developed for 3D printed functional prototyping and outdoor applications due to its high UV stability and resistance to long-term heat exposure.

In terms of its properties, ASA Extrafill has a higher tensile strength (40 MPa) than the ABS Extrafill filament from Fillamentum (32 MPa) and an elongation at break of 35 percent compared to its 20 percent. ASA Extrafill’s ability to withstand heat and UV light also results in less yellowing of the printed parts.

The filament can be subjected to 3D printing processes at working temperatures between 240 and 255 degrees Celsius, whereby it is recommended to set the hot bed temperature between 80 and 105 degrees Celsius. For thicker parts and to prevent incorrect joining and warping of the layers, Filamentum recommends users not to use cooling for standard objects printed with ASA.

With properties such as low moisture absorption, impact resistance and chemical resistance to alkalis, alcohols, oils, fats, ozone and water, ASA Extrafill can be safely used in electrical and electronic devices. The filament is also recyclable, which is in line with the company’s drive to reduce its environmental footprint on the planet.

3D printing with ASA Extrafill

The ASA Extrafill filament from Fillamentum was used by the aircraft manufacturer Future Vehicles to easily and quickly produce 3D printing prototypes and to test the functionality and compatibility of parts.

A prototype plastic cover was printed using ASA Extrafill to improve the ergonomics of the aircraft interior. The company found that the material is suitable for making components that can be “permanently placed on the aircraft”.

The four new color options of the ASA Extrafill range are manufactured in diameters of 1.75 mm and 2.85 mm and are available immediately on the Fillamentum website.

Fillamentum unveils first totally biodegradable filament NonOilen for 3D printing

The Czech 3D printing filament manufacturer Fillamentum has launched NonOilen, its first 100 percent biodegradable filament for 3D printing.

The bio-based filament is made from a mixture of polylactic acid (PLA) and polyhydroxybutyrate (PHB) to achieve improved toughness and temperature-resistant properties. It can be used over and over to adhere to the principles of a circular economy.

As soon as an object printed with NonOilen has reached the end of its life cycle, it can be completely broken down into biomass, water and carbon dioxide (CO2) when disposing of compost or food waste or sent back to Filamentum for recycling. The company has also joined the DHL GoGreen program to neutralize its carbon footprint with every NonOilen package sent through the delivery service.

According to the company, the driving force behind the development of NonOilen was to reduce the use of fossil fuels such as oil to create 3D printable filaments and reduce the company’s ecological footprint on the planet.

Development of a fully bio-based and biodegradable filament

Previous attempts to improve the biodegradability of plastics included the manufacture of oxo-bioplastics, in which standard polymers were modified by adding substances that cause degradation in the presence of oxygen. However, these oxo-bioplastics cannot be sufficiently broken down in the compost, since secondary microplastics, which arise when the plastic decays, can have harmful effects on the environment such as the soil or oceans.

To solve this problem, according to Filamentum, new ways of breaking down such polymers must be discovered. In addition, new sources need to be found to replace fossil resources in the production of biodegradable polymers with high quality inputs and improvements in waste treatment.

To this end, the company’s newest 3D printing filament, NonOilen, has emerged from a long-term partnership with the research team of Professor Pavol Alexy from the Slovak Technical University in Bratislava, Slovakia. The filament is 100 percent biodegradable and all of the polymers used in its manufacture are completely bio-based.

Once an object has reached the end of its useful life, it can be placed in industrial or household compost bins for food waste, which degrades about three times faster than standard PLA. The PHB in NonOilen acts as an initiator for the degradation process, which allows bacteria to depolymerize and metabolize the polymer more quickly.

Alternatively, when the material is sent back to Filamentum, it is recycled and reused several times while maintaining its mechanical properties.

Mechanical properties of non-oils

In addition to its biodegradable properties, NonOilen also has improved toughness, hardness and strength properties compared to standard PLA due to its PHB content.

One of the main advantages of the filament is its temperature resistance of up to 110 degrees Celsius after 3D printing, so no annealing is required. NonOilen is easy to print, supposedly comparable to the ease of printing with standard PLA, with parts having a smooth surface with a natural silk look that is translucent in a thin layer when printed.

Objects printed with NonOilen have a long service life and are harmless for food contact applications. The filament can also be used to make 3D printed electrical components and electronic devices.

According to Filamentum, NonOilen can retain its mechanical properties even after “repeated” recycling. This is an improvement over the company’s other biodegradable filaments, PLA Extrafill and PLA Crystal Clear, both of which exhibit at least some loss of mechanical properties when recycled. In addition, the material outperforms the company’s Timberfill filament, which is biodegradable but cannot be recycled.

NonOilen also has a significantly higher temperature resistance than the company’s other biodegradable filaments and a significantly shorter time to biodegrade.

“Green Prototyping” by NonOilen von Fremach

Fremach, a global supplier of complex plastic components for the automotive market, has tested the NonOilen filament from Fillamentum in the manufacture of control gauges and gears. The company chose the material because of its resistance to high temperatures and its full recyclability. This is a welcome benefit when printing a large number of these components.

The gauges are used to check the positions of symbols on decorative parts that are no longer used after their purpose has been fulfilled. The recyclability of NonOilen is therefore a great benefit for the company and enables Fremach to significantly reduce waste. The 3D printed gears are part of a rotating system for painting cylindrical parts, and here Fremach welcomes the filament’s ability to withstand the high temperatures the gears are exposed to in the pant shop oven without deforming.

“The benefits of 3D printing are obvious and are becoming increasingly important to our business,” said Miroslava Pribylova, process engineer at Fremach. “In addition, Fillamentum’s ecological thinking motivates us to bring our own steps closer to nature.”

In collaboration with Fillamentum, Fremach will regularly collect and recycle unused parts made from NonOilen materials for use in its own production. Starting today, Fillamentum is available for purchase and shipping.

Fillamentum launches ASA 3D printer filament made for extra than simply the outside

Popular brand for 3D printer materials Filamentum has launched three new shades of its ASA Extrafill filament for FFF / FDM. Noting that more and more users are switching from ABS to higher-resistance thermoplastics, the company explains, “ASA is becoming increasingly popular with designers and it’s because of its properties. ASA is ideally suited for outdoor use, but is also ideal for prototyping. “

Fillamentum 3D printer materials

Fillamentum is headquartered in the Czech Republic and is an established supplier of high quality 3D printer filaments. The range of materials currently includes 9 different polymer qualities, from PLA Premium and PLA Crystal Clear to ABS Extrafill and high-tech CPE.

Before the last version, Fillamentum ASA Extrafill was available in nine different colors including Metallic Gray, Natural, Sky Blue, Green Grass, and Traffic Yellow. The three new shades that have been added look significantly more industrial, namely white aluminum, gray-blue and anthracite-gray.

In terms of strength and properties, ASS is often compared to conventional ABS filaments. In fact, ASA was developed as an alternative to its high-strength cousin to improve ABS’s resistance to weather and UV light.

ASA versus ABS

How exactly do the two materials compare? The tensile strength of ASA Extrafill is 40 MPa with an elongation at break of 35% and a flexural strength of 62 MPa.

In comparison, ABS Extrafill has a slightly lower tensile strength of 32/39 MPa (depending on the test conditions), an elongation at break of 20% and a flexural strength of 60 MPa.

The thermal properties of ASS are also superior to ABS. Fillamentum ASA Extrafill typically distorts at temperatures of 86/96 ºC (1.8) MPa Verse 0.45 MPa (test conditions), while ABS has a heat dissipation temperature of up to 81 ºC. Therefore, ASA’s printing temperature is typically higher than ABS, which is recommended in the range of 240-255 ° C, compared to the ABS recommended range of 220-240 ° C.

When printing, ASA Extrafill has strong interlayer adhesion, less comparable deformation than ABS and less styrene emissions. It is also a recyclable material.

A recommended material for prototyping

Like ABS, ASA is not recommended for food contact or medical applications, but it is better suitability for products for outdoor use, and has a higher stiffness than comparable ABS strains. The RoHS-compliant material is an ideal prototype for electrical components. The wide range of ASA colors that Fillamentum offers also helps to better serve these applications, giving designers the ability to create vibrant concepts that approximate the appearance of an end product.

So far, the ASA Extrafill filament series from Fillamentum has received a lot of positive support from its customers. Tom Jackson, the maker of Filament Frenzy channel on YouTube, says, “I haven’t had good results with any ABS and have heard that ASA has some of the same properties. Then I got the chance to try Fillamentum ASA and this product is excellent.

“Combine these breathtaking properties with amazing colors and you have a special material: practical yet beautiful, Fillamentum has done it again.”

ASA Extrafill is currently available directly from Filamentum In 1.75 and 2.85 mm, 750 g spools online and 2.5 kg spools on request. You can check out the new one White aluminum, Gray blue and Anthracite gray Shadow here.
