Quote:Quote:How does the strength of 3D printed parts compare with steel or aluminum parts made by conventional methods? I've seen a contrarian opinion that 3D printers are good only for making worthless plastic trinkets. This is more or less the case. I've worked with parts from SLA, SLS, and even the MakerBot 3D printers and none of them are able to create what I would call usable parts. They're fine if prototyping for packaging and what not but for usable components they are more or less useless.Hobby level printers have come a long way but theres only so much you can do with heating and melting plastic in layers. They're neat for making little toys and stuff but every time I've tried to make a usable part the machines are never able to hold a practical tolerance and the structural integrity is never there.

Quote:My understanding of this technology is that the strength of an object printed with a 3-D printer is really dependent on the matrix (the "ink", if you will). There is interest in medicine for the 3-d printing of solid organs like kidneys, using a variety of different organic matrix materials.Cheap plastics are an easy place to start. They are cheap and easy to extrude. I would be surprised if there aren't a variety of higher strength matrix materials out there in the near future. ...
