Markforged 3D printed parts are known for looking great and being incredibly strong but are they watertight and airtight? We ended up doing a little experiment to find out the answer to this question using a series of printed pressure vessels out of Onyx material on the Markforged X7 3D printer. Each pressure vessel had different wall thicknesses ranging from 5mm down to 2mm thick. I have to admit, the results were surprising!
This experiment was conducted in a controlled environment by trained professionals. Do not try this at home.
