To be fair who is not using them to print buildings too? The issue is you cant actually print many blocks because they are not in craftblocks list. This forces you to put thousands blocks by hand or use only blocks that are allowed but it decreases players creativity what can convince many people to build more simply or even ugly buildings. My solution would be to add every block possible to obtain in survival to shipyard's craftblocks list so builders could build their amazing builds on creative and then not waste time to build them on survival (it already has took a lot of time to build on creative and then will take some time to print anyways). I hope I'm not the only one with this problem so please up vote this if you feel the problem hits you too.
