通过光谱丝
几年来，生态学一直是消费者和工业层面的重要趋势。每年，世界都充满了大量的塑料，其中绝大多数将永远留在我们身边。3D印刷行业的领先公司注意到了这个问题，后者正在连续实施遵循新的亲生态方向的解决方案。其中之一是Spectrum Filooments，它宣布了新产品的首映式以及包装区域的重大变化。
Spectrum Filaments announces the premiere of 2 new eco-materials that will be presented at the Formnext 2022 fair in Frankfurt am Main: the innovativeGreenyHT biopolymer完全生物降解,确保高rature resistance, and Spectrum ecoPET 9021 – a 90% recycled material. Additionally, Spectrum will present new cardboard spools and sets of 5 materials on 250gr spools, offered as one product.
Spectrum GreenyHT
Spectrum GreenyHT is based on a high-performance biopolymer with a softening point (VICAT) of 100°C and thermal resistance (HDT B) of up to 90°C. The material also does not contain additional plasticizers, which ensures the purity of the mixture. In addition to high temperature resistance, in terms of stiffness and hardness, it significantly exceeds the popular alternatives on the market of biodegradable plastics, such as PLA.
Spectrum GreenyHTis fully biodegradable and compostable under industrial conditions defined by the EN 13432 standard. The bio-base comes from non-genetically modified (GMO-free) sources and meets the conditions for contact with food. In the visual sphere, the new filament is distinguished by the characteristic roughness of the 3D printed surface. The irregularity and mattness of the surface effectively mask the layers, significantly increasing the aesthetic value of the printed models.
The filament is wound on an ecological, cardboard spool. The spool contains information about the type of material, diameter, color and recommended 3D printing temperature.
光谱绿色的优势：
- VICAT softening temperature – up to 100°C
- HDT B热电阻 - 高达90°C
- 粗糙的磨砂表面饰面
- no plasticizers
- 可生物降解且可堆肥
- increased stiffness and hardness
光谱Ecopet 9021
光谱Ecopet 9021is based on polyethylene terephthalate (PET), which is not modified with glycol (as in the popular PET-G filaments). The lack of glycol translates into much greater stiffness and resistance to stretching. However, the most important information is that the source of Spectrum ecoPET 9021 is recyclate. However, in contrast to the classic recycling, which consists in granulating flakes from cut bottles, a more advanced raw material was used here, resulting from chemical depolymerization and re-polymerization of waste.
对于经典的回收塑料方法，由于包装是由各种类型的PET制成的，因此很难获得足够的纯度和均匀性。各种材料的混合物和这种混合物的特定化学随机性在细丝的3D打印过程中转化为问题。在解聚和重新聚合过程中形成的颗粒的使用可确保Ecopet 9021的印刷品的质量和便捷性。还值得强调的是，在混合物中，循环含量的份额超过90％。细丝组成。
This approach has resulted in the creation of repeatable, ecological and print-friendly filament, the advantage of which over classic PETG is not only its impressive temperature resistance up to 125 ° C (max. 200h) and low water absorption, but also greater tensile strength and stiffness.
Advantages of the Spectrum ecoPET 9021
- 90% recycled content
- thermal resistance up to 125 ° C (max. 200h)
- 与经典的PET-G相比，拉伸强度提高了20％
- 与经典的PET-G相比，刚度增加了50％
- good chemical resistance
- 印刷后的高表面质量
- 良好的影响力。
Spectrum 5Pack
Another novelty in the Spectrum offer is5Pack – sets of five colors of a given type of filament or a mix of materials in the form of five spools of 250 gr each. The materials are already wound on new cardboard spools. Spectrum 5Pack sets have been prepared so that each customer can create various elements in a wide range of colors and materials without the need to purchase more of a single type of filament.
Cardboard spools
朝着更绿色的未来前进，Spectrum Wilyents做出了战略决定，以开始将其产品部分切换到纸板线轴的过程。由于该公司在相同类型的材料方面拥有60多个目录项目，这些材料转化为数百个项目（考虑到颜色和直径），因此此过程将是渐进的。新线轴的好处已经可以在其来源看到 - 与来自不可再生资源的塑料线轴不同，纸板线轴对环境友好，并且具有较低的碳足迹。新的光谱丝线轴由压制和模切纸板制成，这要归功于它们强大且容易承受所承受的负载。
