By Spectrum Filaments
Ecology has been an important trend at the consumer and industrial level for several years. Every year the world is flooded with tons of plastic, the vast majority of which will remain with us forever. This problem is noticed by leading companies in the 3D printing industry, which are successively implementing solutions that follow a new, pro-ecological direction. One of them is Spectrum Filaments, which announces the premiere of new products in its offer as well as a significant change in the area of their packaging.
Spectrum细丝宣布将在Frankfurt AM的Formnext 2022 Fair上展示2种新的生态材料的首映式：创新性Greenyht生物聚合物, which is fully biodegradable, ensures high temperature 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基于高性能生物聚合物，其软化点（VICAT）为100°C，热电阻（HDT B）的柔软点（VICAT）高达90°C。该材料也不包含其他增塑剂，从而确保混合物的纯度。除了刚度和硬度方面，它还显着超过了可生物降解塑料（例如PLA）市场上流行的替代品。
Spectrum Greenyht在EN 13432标准定义的工业条件下完全可生物降解和堆肥。生物基碱来自非遗传修改（无转基因生物）的来源，并满足与食物接触的条件。在视觉球中，新灯丝的特征性是3D打印表面的特征粗糙度。表面的不规则性和哑头有效地掩盖了层，从而显着增加了印刷模型的美学价值。
细丝在生态纸板线轴上缠绕。该线轴包含有关材料，直径，颜色和建议的3D打印温度的类型的信息。
Advantages of Spectrum GreenyHT:
- VICAT软化温度 - 高达100°C
- HDT B thermal resistance – up to 90°C
- rough, matte surface finish
- 没有增塑剂
- biodegradable and compostable
- 增加刚度和硬度
Spectrum ecoPET 9021
Spectrum ecoPET 9021基于聚对邻苯二甲酸酯（PET），该苯二甲酸酯（PET）未用乙二醇（如流行的PET-G丝中）修饰。缺乏乙二醇可以转化为更大的刚度和抗拉伸性。但是，最重要的信息是频谱Ecopet 9021的来源是回收的。但是，与经典的回收利用相反，该回收包括从切割瓶中颗粒片，此处使用了更先进的原料，这是由于化学解聚和废物的重新聚合而产生的。
In the case of classic methods of recycling plastics, it is extremely difficult to obtain adequate purity and homogeneity of the material, because the packaging is made of various types of PET. The mix of various materials and the specific chemical randomness of such a mixture translate into problems during 3D printing of the filament. The use of granules formed in the process of depolymerization and re-polymerization of the Spectrum precipitation guarantees the quality and ease of prints from ecoPET 9021. It is also worth to emphasize that the share of recyclate in the mixture accounts for over 90% of the filament composition.
这种方法导致创造了可重复的，生态和印刷友好的细丝，而经典PETG的优势不仅是其令人印象深刻的温度耐药性高达125°C（最大200H）和低吸收性，而且还具有更大的拉伸性。力量和僵硬。
光谱Ecopet的优势9021
- 90％回收内容
- 最高125°C的热阻力（最大200H）
- tensile strength increased by 20% compared to classic PET-G
- stiffness increased by 50% compared to classic PET-G
- 良好的耐化学性
- high surface quality after printing
- good impact strength.
Spectrum 5pack
频谱报价中的另一个新颖性是5个pack - 给定类型的细丝的五种颜色或以五个线轴为250 gr的形式的材料混合。这些材料已经在新的纸板线轴上缠绕。已经准备好了Spectrum 5pack集，以便每个客户都可以在各种颜色和材料中创建各种元素，而无需购买更多单一类型的细丝。
纸板线轴
Heading towards greener future, Spectrum Filaments has made a strategic decision to begin the process of partially switching its products to cardboard spools. Due to the fact that the company has over 60 catalog items in terms of the same types of materials, which translates into hundreds of items (taking into account colors and diameters), this process will be progressive. The benefits of the new spool can already be seen at its source – unlike plastic spools that come from non-renewable sources, cardboard spools are environmentally friendly and have a lower carbon footprint. The new Spectrum Filaments spools are made of pressed and die-cut cardboard, thanks to which they are strong and easily withstand the loads they are subjected to.
