Cooling fan cooled the spaghetti, and when enough got formed, outer perimeters started building the Z support.
After some time, the infill actually caught to the flying spaghetti and created a “solid” bottom layer upon other layers managed to stick.
Due to the flexible nature of spaghetti structure, the printed part was wobbling quite much and couldn’t retain the dimensional accuracy 😕
I was just at an art exhibit last week, and I'm confident you should put this in an exhibit. It perfectly represents the stages of a website or software project.
In theory, you can remelt. Unfortunately, the practicalities mean it's not viable. Each remelt cycle degrades the plastic itself, so you can only put 20% or so 'old' plastic into the mix. Combined with the game of plasticisers (to remove brittleness) and reliable forming, even commercial systems struggle, let alone home ones.
If environmental concerns are the issue. It's best to print in uncoloured PLA filament. PLA is corn starch based, and decomposes in a bio reactor environment (it rots quickly in an industrial composter).
As for speed. They are getting impressively fast. A calibration cube takes around 20 minutes, though less than 5 minutes is possible. My machine is effectively fire and forget. They mess around while you are tuning them in, but once you have a good calibration, they now tend to hold it well. You'll sit there watching it in fascination for the first few months, but that wears off.
Part of the reason my printer just sits there not being used, aside from I collect hobbies for fun, is that it’s a nightmare levelling the bed and getting things dialled in.
Resin printers don’t have these issues but it depends what you’re printing I guess.
With resin when a print fails, you just get a half print stuck to the bottom of the resin tank, no spaghetti. The most common cause of failure is the part falling of the lifting platform, typical due to poor supports, but rarelybecause the platform is crooked.
Leveling is pretty easy on most printers, just loosen the bed, remove the resin tank, placing some thin cardboard in it's place, lower the platform until it touches the cardboard, and lock it in place.
Getting an auto leveler was a game changer for me. I still manually level the bed and check the Z offset every two months or so along with other maintenence, but I've gone on week long printing sprees without touching the bed springs once.
You get used to that being a possibility with every print. That’s why you should do everything in your power to have your printer always in shape and operational, although sometimes it will happen no matter what!
Unfortuneatly, this is just waste, straight to the bin.
