3F3D - Form Follows Force with 3D Printing

3F3D - a design method inspired by nature, only put material where it is needed. Using Topology Optimization algorithm to generate the optimized design for multiple structural load cases and using Additive Manufacturing to build them. The design method was executed on structural node joints for freeform gridshell.

Do the designs take into account the anisotropic strength of 3D prints, or is this just a gimmick?

[@BayuPrayudhi]

Yes, the print orientation was also optimized for the anisotropic property. Although I didn't manage to test the strength deviation for different orientation of the printed material, I used other research as reference.

[@muhdismadi1101]

bro this reminds me of the reprap version including that sort of set up i made when reprap started / 3d printing. damn that 1 year of struggling to get the measurement right. But the right answer over the time of building it was. It need proper good adhesion that's it.

[@thzzzt]

I have no doubt that the design is efficient, but my instinct tells me after the slightest bit of deformation, it will fail catastrophically. Am I right? Or does the optimization anticipate that?

[@BrunoLate98]

Topology optimization is defined for a certain amount of deformation according to the max stress on the structure. If the design load is surpassed, it MAY fail

[@AlohaMilton]

"With enough infill... I can support the universe!" its cool but its sort of unexplained. Even weaker plastic filament like PLA can make a part that size with enough structural integrity to do the job of holding the human in the video up. One part. A few arranged distributing the load in a geodesic structure and its a job a modeling foam could do. The final product, a wood frame that will support around 200 lbs, one could print parts in non specific forms and get the same result. so while I appreciate the work that went into this, I would like to see it really demonstrated. The presentation never loads these objects enough to justify the time and effort over simply using a stronger cheaper lighter easier manufacturing material and process.

[@ShaneGadsby]

A side note to you mention of PLA as a weaker filament, considering that it's rigidity and overall strength is second only to co-polymers (reasonable uncommon, even today) I'd say your statement is a little misleading, check out docs.google.com/spreadsheets/d/1j9QazgoocuzHxg6qUXevq3dpAmmT2E87089FX6gRgWU/edit#gid=0, the KZbinr Tom Sanladerer has tested the strength of many filaments, and ranked them against each other. As for your more overall point; if you're looking at this as an engineering feat, you're totally correct, for less work, money, and time, you can make far better structures to accomplish this task (holding a single person, with little to no sheering pressure). But I'd say that this was definitly more for aesthetics, and therefore should be considered an art piece; and art is definitly not about efficiency.

[@omegadeepblue1407]

The software showed in the video is Altair Hyperworks, the same company also has a 3D Modelling software called Altair Inspire, is very useful for design and optimization. Nowadays CAD packages also have the option to run topology optimization and finite element analysis, the problem is that they are not very accurate as using and standalone software dedicated to this. For example i use Solid Edge and instead of use the build in topology optimization module there, i just export what i made to nTopology (for topology optimization, latticing, heavy modification), then return the part to SolidEdge and make a render.

[@torbjrnludvigsen-hangprint7605]

This is so groovy! I will have wet dreams about a 3F3D optimized Hangprinter v3 mover after seeing this. Well done! I think topology optimization makes a lot of sense, given that 1. Forces that your object will experience are predictable. 2. Physical (strength) properties of your object are predictable. Since the HPv3 mover would be built with FFF/FDM 3d-printers, it might make sense to optimize a 2D-shape and then extrude it along Z. Both layer adhesion strength and quality of bridges/steep overhangs are hard to predict on FFF machines. It would be nice if gcode was portable between different FFF machines. This would give the designer better control over mechanical properties of the printed objects, which would make wide spread application of things like 3F3D easier, saving both time and plastic for the whole community.

Cool an all, but you really need to perform fatigue analysis, because static analysis is just the tip of the iceberg. If you perform proper fatigue analysis you'll understand how long your joint lives (even if you use cast aluminum) compared to a regular joint. My guess, space stations would've used such joints if they were a better design choice.

[@omegadeepblue1407]

good point.

[@timhofstetter5654]

Silly demonstration. The force is borne entirely by the wood members; the plastic connectors are only there to keep the wood supporting members aligned and in position. The structure is exceedingly weak in any direction other than straight down, and therefore could not be applied to real-world situations. Moreover, this approach fails to incorporate safety factors which compensate for such things as inevitable decay or unintentional damage. Optimize and fail.

The company I will soon be working with develops and manufactures grippers for robots for the automotive industry e. g. for handling doors, frames etc. They have a catalog of standardized modules for constructing these grippers and already topology optimized a joint which connects profiles. Those joints can be casted like the former design, are 30 % lighter, have a higher stiffness and are cheaper. They are planning a way more topology optimization for standardized parts which I will be part of. Please acknowledge this work and the work in this video.
