Материалы для 3D печати: прочность и печатаемость — инструментальное исследование

In this video we perform strength testing of two kinds of samples produced of almost all general purpose polymers available on the market in filament form. The testing is performed following the standard methodology on a well-proved mechanical testing machine with a three-point bending method. Samples of the first kind (the horizontally printed ones) allow to assess material strength, while those of the second type (printed vertically) to assess the interlayer bonding strength which in turn significantly determines the strength of a sample manufactured on a FFF 3D printer. 0:40 Materials considered 2:15 Disclaimer 2:50 Methodology 4:30 Materials and samples 5:30 Printability 6:32 ABS 8:12 Strength diagram 9:52 ASA 10:52 HIPS 11:22 SAN 12:00 SBS 13:40 PETG 14:20 PLA 16:00 Testing results 17:30 Strong but not durable 21:00 My subjective opinion #3Dprinting #filament
