algorithmic modeling for Rhino

Grasshopper/Rhino tool to create a construction system based on beams and connectors.
Simple lines are drawn in space. Grasshopper generates a ready-to-3d-print set of connectors.

Academic workshop at Burg Giebichenstein – University of Art and Design, Halle, Germany, by Guest-Prof. Frank Spenling, expanding the possibilities of 3d-printing through algorithm-aided design.

Hi, I know this is an old post but, could you send me the definition?

Very cool, much more interesting than I did a while ago .... you will provide GH files?

This is great.  I've managed to create a definition based off of the examples shown, but how do you handle the issue of multiple corners being generated at the same time.  I can't seem to get a corner to create a plane only in the vector/direction of the lines intersecting it.  It seems like they want to create multiple vectors attaching to every point.

That's fantastic! I've been trying to do this for a while - take line geometry and generate the corner pieces to 3d print. I've been trying to create shapes that are more suited to the "reprap" type of 3d printer (because I have one)

The corner pieces shown in the video are a bit tricky to print on the cheaper 3d printers but no problem if you have access to the more expensive printers or a laser sintering system.

The way the software is generating the geometry looks excellent tho. Perhaps look to add (if it is not already a feature) a system to identify the corner pieces and struts to aid assembly! I would definitely consider buying a solution like this one at the right price. (Which would clearly be a cheap price because I can only afford a reprap printer :)

Hi Frank have you shared your definitions for this course anywhere? if not is it possible for you to share?Thank you, this is some great work!

Funnyyy, just been working on something v similar.

Thanks Nick. It is interesting to see the range of projects dealing with this subject. Let's see what more is to come...

Thanks Nick. Looks great!

Nice work Frank!

djordje, is this the project you are looking for? Its very similar, they didn't optimise their structure though either, but they did analyse it and then painted the final structure to display the forces at work internally. I've always wanted to give the 3d printed node a go, but haven't got round to it yet.

there is a pretty cool video of it all here:
