Open Source Ecology - Ecohome construction using 3D printing

Interesting. What other 3D printable construction materials are you alluding to, if I may ask?

There are a lot of things that can be printed for large reductions in cost. Here’s work on this from the wiki: https://wiki.opensourceecology.org/wiki/Seed_Eco-Home_Materials_Cost_Reduction

Also, there are many applications where the strength of stock steel can be combined with 3D printing for extremely strong composite construction: https://wiki.opensourceecology.org/wiki/Plastic-Metal_Composites (edited)

Plastic-Metal Composites

Interesting... I'm familiar with binder jetting, where a metal-plastic composite filament is used to print an fdm printed part followed by a bakeout process to essentially melt out the plastic and bind the metal. Is that the idea here or is there some advantage to keeping the plastic element part of the finished product? I'm reading that the fabrication of screws/fasteners would be a use case of interest, but something like binder jetting would require accounting for the shrinkage due to loss of plastic during the process

Speaking of "metal 3d printing", Sunshine recently published a video where he essentially electroplates metal onto an fdm printed surface as each layer is being printed https://www.youtube.com/watch?v=W1d36wbx_yg

Regarding the fabrication of screws/fasteners using 3d printing, I've contemplated whether an SLA 3D printed lost-resin casting process could work...

(Full disclosure, I was on the path of pursuing Material Science Engineering in a past life, before switching degrees to Mechanical Engineering)

The plastic metal composite design is actually combining stock steel like rebar, angle, plate, sheet, nuts and bolts, etc with plastic for complex geometries. An example is a plastic vise with a metal bolt for tightening or loosening and metal plates for the jaws, etc.
