Italian 3D printing materials manufacturerCRP Technology已经在其Windform顶部的复合材料家族中推出了一种新材料，用于增材制造。Windform FR2专为选择性激光烧结（SLS）工艺而设计，是一种基于高的聚酰胺玻璃纤维增强材料，旨在在航空航天，汽车和消费品中应用。
CRP的新Windform FR2遵循Windform FR1in 2019, and the two materials differ in a number of ways, as explained by Franco Cevolini, VP and CTO at CRP Technology: “Only a few months ago we launched Windform® FR1, flame retardant carbon fiber reinforced material,” comments Cevolini.
“现在，我们引入了Windform®FR2，这是一种阻燃材料，是玻璃纤维增强的。”
Windform FR2
CRP的标志性线中的第一个材料，Windform FR1是一种基于碳纤维增强的聚酰胺材料，旨在用于飞机，航空航天，汽车和运输，消费品和电子产品的应用。
As well as being reinforced with glass fiber, the new Windform FR2 is different from the previous material in its color. The FR2 is an off-white, whereas the color of the FR1 material is dark gray. Additionally, the Windform FR2 is electrically insulating, thanks to its glass fiber reinforcement. Compared to the Windform FR1, it provides improved detail resolution and a smoother surface finish after 3D printing. Both are polyamide-based which helps to provide wear resistance and good temperature resistance.
Thanks to its combination of flame-retardant and insulating properties, the FR2 can be used to manufacture parts like casings of electrical and electronic components in the automotive industry, or lighting and appliances for consumer goods. Ensuring its flame-retardancy, the material passed the FAR 25.853 12-second vertical and 15-second horizontal flammability tests as well as the 45° Bunsen burner test and Smoke density test.
为什么要开发阻燃材料？
CRP响应于行业中明显缺乏阻燃材料而推出了Windforf FR线，这些材料已加强了其他材料以改善其机械性能：
“Flame retardants are not new to the 3D printing market but flame-retardant materials which were also reinforced and presenting significant mechanical properties, lacked,” adds Cevolini. “We at CRP Technology were the first to fill this void; we have created not only the first material of its kind, but now two. In order to invent these materials, we must anticipate, intercept and satisfy the requests of the most demanding and innovative industrial sectors.”
As well as releasing a new addition to its Windform FR-line, CRP Technology also recently updated itsP-Line加法制造材料，专门用于High-Speed Sintering（HSS）技术。这Windform P2是一种玻璃纤维增强材料，旨在生产小型功能原型以及消费者，家庭和工业产品。
CRP Technology’s Windform materials have been used to make parts for a number of different applications in recent times. It has been used to manufacture components for theEnergica Ego，意大利的第一个street-legal electric motorbike. The materials have also been leveraged to 3D print a3U CubeSatby students at theLaboratoire InterUniversitaire des Système Atmosphérique（丽莎）巴黎最佳克里特氏菌（UPEC）。
