eSUN Nylon PA12 Filament 1.75mm 3D Printer Filament 1KG 3D Printing Filament for 3D Printer ราคา 2000
ePA-CF
eSUN ePA-CF is a robust filament developed based on Nylon 6/66 copolymer and enriched with 20% carbon fibre. It has increased strength, rigidity and toughness and can replace metal materials in many cases. Its self-lubricating wear resistance makes the filament ideal for printing gears.

ความทนต่อแรงดึง (Tensile Strength) คือ ความเค้นดึงสูงสุดต่อหนึ่งหน่วยพื้นที่ของชิ้นงานที่ได้รับจนเกิดการขาด
MELT FLOW INDEX TESTER เป็นเครื่องทดสอบหาค่า MFI. ( Melt Flow Index ), MFR. ( Melt Flow Rate ) หรือ MI คือ ดัชนีการหลอมไหลหรืออัตราการไหลของเม็ดพลาสติก
ความแข็งแกร่งแรงดัด (Flexural strength) หมายถึง การที่วัสดุสามารถทนทานต่อแรงที่จะท าให้วัสดุเกิดการ โค้งงอ หรือความแข็งดัดของวัสดุหนึ่งๆ
Flexural modulus = property that is computed as the ratio of stress to strain in flexural deformation,
