Canadian start-upfortis3dis launching two new 3D printing materials for a range of industrial applications. Accompanying the launch ofPA-GF20，，，，andPK-GF20，，，，fortis3dhas provided a detailed analysis of each filament’s material characteristics to allow engineers to understand the strengths and suitable applications.
Fortis3D的科学家和工程师团队在聚合物工程的背景下创建了增强的聚酰胺（PA），尼龙和尼龙和聚酮（PK）3D打印丝，它们比其他人更强，并具有较低的玻璃纤维含量。
“我们发现，市场上大多数纤维增强的细丝都会产生相对较强的固定零件，但是它们远不及传统的纤维增强树脂来进行注射成型。我们还希望使更多用户可以使用高强度的材料，而不仅仅是那些拥有昂贵工业机器的用户。考虑到这两个目标，我们开发了这两种材料，使其成为市场上最强大的材料，即使是具有中型打印机的用户也可以制作出非常高强度的零件。” Fortis3D业务经理Wayne Lam说。
PA-GF20和PK-GF20的特征
fortis3d’s PA-GF20 and PK-GF20 chopped glass fiber-reinforced materials are intended for 3D printing high-performance functional components. In addition to superior mechanical strength, both have chemical, high temperature, impact, and wear resistance, making them durable in severe environments. The materials have applications ranging from industrial end-use parts to jigs and fixtures.
其他玻璃纤维增强纤维industry use ground glass fiber that is very short (100-300µm) and incorporated into various resins. They can be brittle despite having good strength and printability. Chopped glass fiber is longer (3mm) and provides very high strength while preserving more toughness of the base plastic material, but is more challenging to incorporate. Both types of fibers will usually break down more during the compounding process, resulting in shorter fibers in the end product; hence precautions must be taken while processing to minimize fiber breakage.
PA-GF20和PK-GF20 3D打印材料的技术数据
Fortis3D的开发团队优化了纤维的负载和加工变量，以在较低的玻璃纤维载荷中生成该部门中“最强”的纤维增强PA细丝之一。减少的玻璃纤维载荷可增强可打印性，喷嘴磨损和表面饰面。为了达到78MPa的高抗拉强度，还采用化学耦合剂来增强玻璃纤维和聚合物基质之间的粘附。
In comparison with injection molding, this delivers tensile strength preservation of over 90% and is tougher than other leading brands’ glass and carbon fiber-reinforced nylon materials. Compared to a typical PA6GF filament, moisture uptake is lowered by 30% when employing a similar nylon copolymer as Fortis3D’s SnapPrint PA. Stringing is minimized even when the filament is left out in ambient conditions as opposed to a PA6GF filament.

聚酮（PK）是丙烯，乙烯和一氧化碳的特来聚合物，具有类似于PA12的特征，但吸收水分吸收降低，化学和撞击性较高，抗撞击性以及摩擦和磨损降低。与尼龙不同，它还在吸收水分后保持机械强度。在环境方面，多酮产生的二氧化碳产生比尼龙生产少60％。但是，由于经过过度的经过过多的经态以及对大多数床胶粘剂和材料的粘附，因此很难独立打印。为了解决这一问题，Fortis3D的开发团队创建了一个专有的配方，可以大大降低经线，并可以使用仅PVA胶水遵守大多数床材料。添加切碎的玻璃纤维以提高强度和刚性，从而产生与行业中其他碳或玻璃纤维增强的尼龙相媲美的材料，而没有过多吸收水分的危险。与典型的PA6GF细丝相比，水分吸收率低约70％，这意味着在环境条件的一周后，串线有限，零件强度不受影响。
