Hi Joshua,
We are planning to run a $100k reward campaign on HeroX next year. We switched from cordless drill to large, high T printer with 4x4x8' build area, vertically. This is to address real needs, namely related to housing. The large printer would include filament making infrastructure for producing filament. We are not doing a pellet printer, since we want to work with filament printing for leveraging the existing base of fused filament printers. Given the 20 lb/day limits of Supervolcano style printheads, we don't see an issue with throughput. We also plan on doing a 4-headed version, so we have 80 lb/day print capacity with a single printer. There is the extra step of making filament, but at our documented electricity cost of 1 cent/kg to do this (https://docs.google.com/presentation/d/1M9p8GeZDAs0EJgMdgtnzObiqp-38ZpG-YwhImb645nw/edit#slide=id.g920dac51f5_0_0), energy inputs are not an issue either.
Is it true that pellet-based printing still needs some development to be available in the open source? That is why we want to go with the filament route at this time.
In any case - I wanted to ask if you see any limits to using FFF to make PVC-ABS-polyolefin blends for 3D printing of large objects. This would allow for absorbing all the waste plastic from typical consumer waste streams and turning them into bulk printing filament for construction applications.
What do you see as the major blocks to taking PVC/ABS/polyolefin wastestreams and blending them for bulk construction printing? Or would you suggest something else? I know people are talking about PET as a good candidate for recycling - but there is much more PVC available. There are of course the outgassing safety issues to consider. (nice work on the coatings for outgassing paper, btw).
