Remember GREENFILL3D? A start-up that recently developed a new 3D printing material based on wheat bran? Well, the team has unveiled an unusual line of products called COLORISED.
This line of full-color lighting accessories does not only have a decorative purpose. They can also serve as frames for electrical switches and sockets, frames for LED lamps, as well as the light switches themselves. Thanks to 3D printing, they can have any shape and size.
With the goal of remaining faithful to its mission of creating functional everyday objects using ecological materials – biodegradable, compostable or recycled, the company has worked with the materials provided by the Chilean Copper3D and three Polish companies: Grupa Azoty, Spectrum Filaments and ROSA 3D.
One example of the use of COLORISED products can be lighting accessories installed in hospitals and medical facilities. Thanks to cooperation with Copper3D – a Chilean company that has developed innovative filaments doped with copper nanoparticles, they will have antibacterial, antiviral and antifungal properties. The materials are made on the basis of polylactide (PLA), which is biodegradable in industrial conditions, and a patented, scientifically proven and highly effective nano-copper additive. The PLActive filament is registered by the FDA and eliminates over 99.99% of fungi, viruses, bacteria and various microorganisms. It complies with the European Union standards: No. 10/2011, No. 1935/2004 and No. 2023/2006. It has been clinically tested in dentures with excellent results.
Another type of application are products made of fully compostable materials – also at home. GREENFILL3D cooperates in this area with two companies. Grupa Azoty S.A. is the largest chemical company in Poland. It was founded in 1927 as one of the most modern factories in Europe at that time. For several years, it has been developing its own line of materials for 3D printers, which consists of technical and high-performance filaments as well as fully biodegradable and compostable ones based on, among others, on thermoplastic starch. Tarfuse envi 1 is degraded in the natural environment in the presence of microorganisms. After the biodegradation process, only natural and harmless substances such as water, CO2 and organic matter remain. The filament recipe was developed with environmental protection in mind and during degradation it emits less CO2 into the atmosphere.
ROSA 3D is a brand of filaments created by ROSA PLAST – a company with over 40 years of experience in the plastics processing industry. It has a very wide range of materials, focused on eco filaments – including BIOwood, a compostable material mixed with wood. Regardless of this, ROSA 3D specializes in decorative, multi-colored PLA – in this respect it is the largest manufacturer in Europe. GREENFILL3D uses materials of this type to produce larger products such as lamps or ventilation grilles.
Last but not least, in addition to a very wide range of technical and high-performance filaments, Spectrum Filaments develops a line of ecological filaments that, on the one hand, are biodegradable, and on the other hand, provide very high mechanical strength and temperature resistance.
Last year, the company presented GreenyHT – an eco-filament based on a high-performance biopolymer with a softening point (VICAT) of up to 100°C and heat resistance (HDT B) of up to 90°C. Importantly, Spectrum GreenyHT does not contain plasticizers, remains fully biodegradable and compostable in industrial conditions, as defined by the EN 13432 standard. The bio-base comes from non-genetically modified sources (GMO-free).
