An Italian AM materials maker, CRP Technology has unveiled fresh elements in its Windform TOP-LINE class of composite supplies for 3D printing. The Windform FR2 is a flame- retardant polyamide-dependent glass fiber reinforced material. It is created for the selective laser sintering procedure. It is also intended for processes in consumer goods, automotive, and aerospace.
CRP’s latest Windform FR2 comes after the unveiling of Windform FR1 in 2019. However, these two materials differ in several ways.
“Only a few months ago we launched Windform® FR1, flame retardant carbon fiber reinforced material,” says Franco Cevolini, VP and CTO at CRP Technology.
“Now we introduced windform® fr2, a flame retardant material which is glass fiber reinforced,” he added.
The initial element in the flash-retardant series by CRP, the Windform FR1 is a carbon fiber strengthened polyamide-based element created for processes in aerospace, aircraft, transportation and automotive, electronics and consumer goods.
Apart from being strengthened with glass fiber, the latest Windform FR2 is diverse from past material in its shade. The FR2 is an off-white, while the shade of the FR1 elements is dull gray. Furthermore, the Windform FR2 is electrically heatproofing. This is owing to its glass fiber coating.
When matched with the Windform FR1, it offers enhanced detail presentation and a gloss surface polish after additive manufacturing.
All of them are polyamide-dependent and this assists to offer wear protection and good temperature proof.
Owing to its mixture of insulating and flame retardant attributes, the FR2 may be utilized to make pieces such as electronic and electrical parts casing in the lighting or automotive sector and appliances for consumer goods.
Making sure it is heat-retardancy, the element crossed the FAR 25.853 12-second vertical and 15-second horizontal burnable experiments. This also includes the 45° Bunsen burner experiment and Smoke density experiment.
CRP unveiled its Windform FR chain in reply to an obvious need for flame-retardant elements in the sector. These were those that have been strengthened with other stuff to enhance their mechanical attributes:
“Flame retardants are not new to the 3D printing market but flame-retardant materials which were also reinforced and presenting significant mechanical properties, lacked,” says 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.”
Apart from unveiling the newest inclusion to its Windform FR-line, the firm recently upgraded its P-Line of 3D printing materials. This is a range committed to High-Speed Sintering technology.
