hi,
after spending now 4 weeks full time, I wanted to share our build and experiences.
Here first some **requirements of the work station
**– disposable design
– using standard tubes or bars only – , along an easy to extend metal frame/table, leaving space for automation and being able to install all 4 machines on one setup
– must run stable, 24/7
– scale-able: the motor/reducer must be able to run 2 shredders, and 2 extrusions
– movable with a car, for exhibitions
– safe and clear to use
– easy to manufacture components (drive shaft, couplings), reproducible by any classic machine shop, not more than a lathe, mill & CNC
status:
– compression/injector not build/integrated yet
– extrusion build but not wired and tested yet
references
– parts, prices, overhead and details here in a sheet
– build log (pictures for now only)
**
key performance indicators
**:
build time: insane, we’ve made the couplings, drive shaft and extrusion our self
kw hours to produce & test: 180
used / new – ratio: 30/70
man power: 4 man weeks, full time
price – materials: 1400 Euro
price – labour: 1500 Euro (friend price)
real price: 3000 Euro (if used only new parts and market prices)
footprint – materials/labour: high
efficiency or production to produce this machine: 60%, 40% is lost for weird surprises
**
started addons
**(not incl. above)
– pulley system for filements: 30 euro
– regulated water beds to make filaments: 100 Euro
– integrated washing: 100 euro
– vibrators for the sive: 20 euro
– coolers for the extrusion: 100 euro (absolutely needed to make good filament)
– different hopper with pusher: 20 euro
– another gearbox with standard gears for the extrusion: 100 euro
– water proof control panels: 20 euro
