The idea with 3D printers is not new, that year they were already there, and as far as I remember, not one was not successful. You have a good and bright website, but the announcement looks poor.
Maybe add some snippets from their website at least. Their min contribution during pre-sale is 10eth. So quite large amount of money for small timers. They might want to lower such amount as the crypto market is not making any good progress at the moment.
There are a lot of similar projects and they didn't work in the past year. But this time it could have been successful if they actually announce it well maybe some investors will begin to see here. Team just enough to make a big change on this project so as to make this project is different from the others.
