Solidworks model and approximate Bill of Materials of a Delta Arm 3D Printer. Assembly size is ~100MB so open in large assembly mode! Based on Werner Berry's BerryBot 3D. Here is Werner Berry's YouTube Channel: http://www.youtube.com/channel/UChZIa-t7aKDU2TE7tAuY3IA
Solidworks note: There are 3 mates inside the carriage folder securing the 3 carriages. suppress those 3 mates in the folder and you can move the hot end platform around.
Named "Delta Mines" for the university it was used at.
Print size: 16'' diameter x 17'' tall.
Estimated cost from scratch: ~$2,500 (Including wire, switches, etc...)
4 nozzle hot end (bowden setup) Water cooled using condensate pump and radiator. heater cartridges are 100vac at 100 watts from McMaster.
nozzle assemblys are secured loosly with a shaft colllar with a plastic insert betweein the tube and set screw to prevent head crashing.
aluminum construction (Aluminum panels and 20mmx20mm aluminum extrusion support framing)
nicrome coil heated circular platform with 2 circuits (large print or small print)
Makerslide vertical members and v-groove sliding carriages
spring loaded heated platform
magnetic ball joints = no backlash --> high accuracy
carbon fiber rods
screw/ worm drive for bowden setup
lazy susan filament spooling. (needs improvement)
acrylic windows with magnetic door latch
electronics in base
removable magnetic display (not shown)
belt driven sliding carriages
ATX power supply powered.
heated bed heat reflector underneath
Eccentric spacer belt tensioner
Vertical columns are easily extendable once Inventables.com gets longer makerslides
Suggestions for improvements welcomed.
Note: Check my Worm Drive Extruder for bug fixes on that component.
