Any interest for Sustainable PLA grown from food waste - not corn!

· Any interest for Sustainable PLA grown from food waste - not corn!
Yes, but: the filament should be equally strong, durable, easy to print, non-warping, and have the same layer bonding as standard PLA, I think. And it should not damage brass and steel nozzles, e.g. not be so acid that they dissolve, and not leave burned residu stuck to the nozzle. And at a comparable price as PLA now. Also, production should not use more energy than it does now. And it also should not be so self-decomposing that prints fall apart, like we had with some other bio-stuff: in our city we once had waste bags (NL: vuilniszakken) that were so bio that they decomposed in two days, but the truck came only once a week...
The traditional "bio" way of doing things, twice as expensive for half the quality, is not going to work here, I am afraid. The amount of waste coming from 3D-printing is already very minimal compared to the amount of waste coming from most household- or industrial processes. There is not that much to gain for average users.
I think you have to calculate all these things in from the beginning.
That said, do not stop researching, even not if you do not have success immediately. All good things we have now, came from continued research and development. A lot of new inventions were inferior to existing things in their first iterations, but became better later on.

In the Cura 5.8 stable release, everyone can now tune their Z seams to look better than ever. Method series users get access to new material profiles, and the base Method model now has a printer profile, meaning the whole Method series is now supported in Cura!
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
