3D Printed Joinery in Keystones Furniture by Minale-Maeda
Interesting…my College degree had a structural concentration. Quite a bit of THAT dealt with transferring forces, this shows some compression forces leading to a bending deformation on the legs.
There’s a question of: is the printed part strong enough for all potential loads? I also don’t see the beam that’s parallel to the table doing much of anything. If there was a mechanical attachment to the top of the legs, and some pins connecting wood to wood…as it stands, I can’t tell if the as-presented solution is a good one or not.
@Mike_Miller I think the center beam is just to prevent the legs at either end from splaying or collapsing inward.
Personally, these pieces of furniture look scary to me. They don’t look like load bearing furniture, more like non-functional decoration
Now that’s a slick idea have you seen the wiki for New Zealand house
Built the whole house on the CNC router table
Technology like this for the table could be used in such a house fit right in
@Josef_Wesselak I hadn’t heard of that but thanks for bringing it to my attention. Is this the project you meant?
@Mike_Miller
If there are pins, then the printed stuff is mostly decorative.
If there aren’t pins between the ends of the struts and the tabletop, it doesn’t seem like a good solution. For example, any weight on the edge of the table will be converted into tension in the two little bands on the top face of the leg. I’d guess that two 10mmx3mm cross sections of perfect 40MPa ABS might fail at 2400N, and with a 3+:0.5 lever arm, a 400N half-buttocks at the end of the arm would break it.
These look like concept design/artsy tables for a museum rather than functional. Attractive looking, though.
Agree pins would make all the difference.
