WITHDRAWN: RESEARCH ON IMPACT RESISTANCE USING FREE-FALLING DART DROP TESTING OF 3D PRINTED PARTS MADE OF ABS AND PETG ACCORDING ASTM D1709
The paper investigates impact resistance of 3D printed ABS and PETG specimens by a falling dart drop. 25 specimens of each material were manufactured in accordance to ASTM D1709 standard, as well as 25 specimens of notched ABS. The test data is processed when 10 cracked and 10 uncracked specimens are available. Dart drop tests are typical for specimens that are manufactured in shape of films. The purpose of the test is to perform an impact from a certain height with a controlled velocity of the falling dart drop.
