[Printing] Subdivision bracelet
This is a beautiful bracelet. Designed by nervoussystem [http://www.thingiverse.com/thing:7048]
While supports is often required for undercuts and hangovers, they are a disaster for an organic and intricate design if we don’t have the soluble filament for them.
The first bracelet was printed without supports and rafts. (Note that in this case, raft is not necessary as the contact area with printbed is relatively small.) However, an organic design means A LOT of hangovers and there were time that the nozzle would just fuse your filament into empty air and create a crumbled lump of spaghetti.
The second bracelet was printed with full raft and supports. Yes, the printout looked ‘supported’. Yet I was undermined the difficulty of removing all the little rafts intertwining with the ‘veins’ of this bangle. I gave up after spending about an hour and a half to pick them out bit by bit, breaking a couple of smaller veins, and still leaving about 30% of the supports that lie in between the two walls.
Haven said all these, I still insist that the bracelet is really nice. It would be perfect if I would have used a soluble filament for supports (eg. HIPS or Nylon). Will do next time, definitely :)
