通过光谱丝
Spectrum Filaments– one of the largest European materials manufacturers for 3D printing in FDM / FFF technology, will present a range of 8 new technical materials at the Formnext 2022 fair in Frankfurt am Main. Among them are composites of Kevlar (aramid fibers), PTFE (Teflon), carbon fibers, and glass fibers. The offer will also include high-temperature PPS AM230 material offering softening point (VICAT) as high as 236°C.
Spectrum Filaments has been operating in the additive manufacturing market since 2015. The company’s offer includes over 60 types of filaments in different variants, which translates into several hundred catalog products. The company produces and sells materials under its own brand, as well as serves as a contract manufacturer to many reputable entities. The company’s filaments are dedicated to working with both amateur (budget) as well as desktop and industrial 3D printers.
Each manufactured spool undergoes a very precise quality control system – Verify your spool. During production, the filament is continuously measured in 2 axes with ±0.8µm accuracy, which creates a high-quality final product. To prove this, Spectrum Filaments publishes parameters individually for each manufactured spool:
- the course of diameter on the entire length of the spool,
- 平均直径，
- ovality,
- standard deviation.
New Spectrum materials to be presented at Formnext 2022 will be available via the manufacturer’s distribution network in mid-November 2022:
阿萨·凯夫拉（Asa Kevlar）
Spectrum Asa Kevlar是一种技术复合灯丝，基于ASA共聚物与芳族纤维的组合（最强的合成纤维之一）。Aramid纤维用于生产具有高阻力损坏的物品，例如防弹背心，头盔或扬声器膜。
Aramid本身是一种对紫外线辐射具有耐药性的材料，但是由于将其与ASA结合在一起 - 一种高度抗性的材料可确保纤维的长寿命和整个复合材料。与碳和玻璃纤维不同，凯夫拉尔纤维显示出3D打印机喷嘴的磨损明显较小。纤维结构的使用减少了3D打印过程中的材料收缩，从而可以生产大部分。

ASA-X CF10
Spectrum ASA-X CF10 material characterized by high resistance to external conditions with a beautiful carbon finish. This filament is an ASA-based composite filled with 10% carbon fibers. The parts made of the material are resistant to external exposure such as sunlight (UV) and humidity. Its tensile modulus is over 7.5 GPa and its thermal resistance is 101°C. At the same time, the Spectrum ASA-X CF10 is characterized by low shrinkage and very easy printing processability.
3D printing Specs:
- printhead temperature: 235-260°C

PPS AM230
Spectrum PPS AM230 - 基于具有异常高机械参数的工程PPS聚合物的高性能灯丝。即使在高温下（以上100°C）下的恒定应力下，刚度和强度也保持不变。Spectrum PPS AM230显示了最高236°C的软化点（VICAT）。
细丝还具有明显的耐化学性特征 - 实际上，它在任何已知的溶剂中都无法溶于包括浓酸和碱。Spectrum PPS AM230的一个特征是它的天然非易用性，即使不使用阻燃添加剂。

PETG/PTFE
Spectrum PETG / PTFE – as a basis for the material was used Spectrum PET-G Premium, well-known for its excellent mechanical properties, is supplemented by adding 10% PTFE, commonly known as Teflon, with self-lubricating properties. Thanks to the proper selection of components while reducing the coefficient of friction, the filament maintains the ease of 3D printing, interlayer adhesion, impact resistance and thermal properties characteristic of PET-G. The filament is available in different colors.
3D printing Specs:
- 打印头温度：235-255°C
- printbed温度:60 - 80°C
- 3D printing speed: 30-70 mm/s

PA6低翘曲CF15S
Spectrum PA6 Low Warp CF15S designed for the production of high performance parts. The “LowWarp” line is characterized by additional admixtures aimed at improving the flow during 3D printing and better adhesion of material particles. The use of 15% of carbon fibers results in more than twofold increase in stiffness and increased tensile strength (up to 120 MPa). In addition, Spectrum PA6 Low Warp CF15S has an improved HDT thermal resistance: 180°C (0.45MPa), compared to the unfilled version. The fiber content lowers the shrinkage characteristic for most high-temperature materials, significantly facilitating the printing process and gives the printouts an aesthetic, “carbon” look.
3D printing Specs:
- printhead temperature: 250-280°C
- printbed temperature: <80°C
- 3D printing speed: 30-70 mm/s
- heated working chamber: recommended
PA6 Low Warp GF30
Spectrum PA6 GF30 – a thermally stabilized 30% glass fiber reinforced copolyimide, mechanically improved in terms of tensile and compressive strength. The fibers have a less aggressive geometry, limiting the degradation of the 3D printer nozzle. The material is used for 3D printing of parts requiring high mechanical parameters, high hardness and thermal resistance. Spectrum PA6 GF30 has a temperature resistance of 180°C (0.45MPa), which puts it at the forefront of materials dedicated to desktop 3D printers.
3D printing Specs:
- printhead temperature: 250-280°C
- printbed temperature: <80°C
- 3D printing speed: 30-70 mm / s
- heated working chamber: recommended
PCTG CF10
PCTG – a copolyester characterized by much greater impact strength compared to the popular PETG. High flexibility of PCTG combined with high layer bondability, high viscosity and negligible shrinkage make it an ideal polymer for composing composite materials. Spectrum PCTG CF10 is a composite with carbon fiber – the fibers used give the filament extremely high stiffness, while reducing the brittle cracking characteristic of other copolyester-based carbon composites. They also increase thermal resistance, reduce shrinkage and give the characteristic “carbon” matte appearance to 3D printed parts.
3D printing Specs:
- 打印头温度：250-270°C
- printbed temperature: 50°C
- 3D printing speed: 30-80 mm/s

PCTG GF10
Spectrum PCTG GF10是另一种复合材料，这次充满了玻璃纤维。它具有高耐用性和哑光表面。与PA6低翘曲GF30一样，它还使用具有侵略性几何形状的纤维，从而减少了3D打印机喷嘴的降解。Spectrum PCTG GF10是一种具有高刚度和硬度的技术丝。得益于极高的层间粘附力和低收缩，即使是中间用户，它也可以启用大型印刷品。
3D printing Specs:
