The guy who made the bimini must have a printer that is much stronger..?
one of the youtube posts was saying they use a 3D printer to make the molds for injection molding

we have several 3D printers within our company that we use for prototyping and fit checks but the material is not really suitable for structural usage.

A designer that used to work for me, ventured out and purchased a very high end 3D printer ($250k+) that uses a variety of different materials from flexible like rubber up to extremely rigid. He must be doing fairly well after about 2 years in business.

My Naval Architecture department has one that the navy financed that was over 200k and is capable of printing many different materials and has very good resolution...but even with a machine like that the work envelope is rather small and the material is expensive.

For a class last spring the project was to design a propeller and then we got to print it. The prop was 14" dia and the material cost was $125.

As of right now they are great machines to give the business types something to see and feel and to test proof of concept but as of right now they have a way to go before you are printing production quality parts at an economical rate.

Played with several different machines when I was in school (mech eng).

Example of a company who's entire business model is built around the technology - Invisalign.

I read this on Christmas. Crazy they printed a weapon and it fired 6 times before it broke. Its like the Jetsons. Soon everyone will have one of these 3d printers. No more lost keys. Just print new ones.
