  1. Thanks! This is very insightful. I am quite new to 3D printing. If I understood correctly, first of all I need to use a very thin extruder, like 0.06mm. Then I need to 3D print with high density. Considering the size of the item is roughly 10 cm diameter x 30 cm height, how long would it take?
  2. Thanks for the suggestions. What coating do you have in mind? Epoxy? Is there a specific product and if yes, what filament should I use with it to achieve the end result I am looking for? Unfortunately I cannot make the whole surface oval. I could make the bottom round though. It would not be possible to use it. This canister is placed on the waste belt of a diver, It would become too inconvenient with that shape.
  3. I am trying to 3D print a diving canister used to store battery packs that power underwater torches, heating elements, etc. Traditionally these canisters are machined with a lathe using Delrin acetal homopolymer (Polyoxymethylene POM). They are often rated to 200 or even 300 meters (600-900 feet), which means 21 to 31 bars of atmospheric pressure (300-450 psi). This is how a Delrin machined canister would look like: And this is one of the 3D model to be used for 3D printing: I know POM-C is available from FrontierFila and Uayella as
