Material selection, sea water resistance

#1

I am wanting to print something that will hold up after repeated and often extended submergence in sea water. Would the waterproof treated polyamide be suitable?

Thank you in advance.

Polyamide (SLS) can be treated with a sealant to fill small pores, thus making your model airtight and watertight. However, i.materialise is mostly focused on consumers and students who mostly order more cosmetic models without technical requirements. So, unfortunately we can’t give any guarantees after repeated and often extended submergence in sea water.
