In this work I am testing antibacterial and antimicrobial filaments from food safety aspect. Three filaments will be tested:
- Copper 3D: PLActive
- Purement antimicrobial filament
- Philament antibacterial PLA
For comparison I used regular Prusament PLA as reference material (not antibacterial). This is not sponsored video, I bought these filaments. For Copper3D and Purement I bought only 20m samples from globalfsd.com, and from Philament I bought a whole spool.
I recommend you to see my first video about food safe 3D printing, because few things will not be mentioned in this work:
Contents:
0:00 introduction
2:00 tested antibacterial filaments
5:35 antibacterial tests
7:42 results of laboratory test
8:29 mechanical tests
11:11 results of mechanical test
12:11 moldy test
12:47 conclusions
Most important part of the test will be testing their antibacterial property with cups simulating using in kitchen (with milk). These tests were made by University of Novi Sad.
Second part of the test will be mechanical tensile testing, only one test probes for each (horizontally and vertically printed), just to see is there any significant difference in strength.
Third is less scientific test, to see if moldy bread will leave some mark on this plastic, but without success (no noticeable difference on surface).
