Cut List

Using 3D Printer Workbench 2020:

  1. X - [2] 22”
  2. Y - [4] 21”
  3. Z, bed, spool holder - [9] 17”

Heater Element

(See Nichrome Calculator)

Notes:

  • Fiberglass sleeve used - HTG fiberglass, does not fray like standard high temperature sleeving (1000F) and is rated for . See [1]. Note that the resin can burn out at the 650C (1200F) workign temp. Sleeve has VW-1 flame resistance. Made of fiberglass, it does not burn out, but may fuse and lose fiber structure.
  • Inner core: 5' long wraparound of 2mm tight braid fiberglass sleeve - 600C - [2]
  • This is packed into 6' of 6 mm tight braid fiberglass sleeve.

Heater Optimization

Theoretical idea:

But, ga 18 can't bend easily using a cordless drill.

  • 20 feet of 20 ga wire appears to be most convenient - 1 piece, max at 1200F. Current 500W heater is 1200F max, and works well.

  • 14 feet of 24 ga works perfectly by hand to get a good wrap over 4 feet, and goes fast, about 1 minute pending tieups:

Heater Element Build Procedure

  1. Cut 14' of ga 24 nichrome
  2. Cut 5' of tight 2 mm fiberglass sleeve
  3. start the wrap of nichrome on one end of sleeve
  4. Attach other end of sleeve to a free-spinning rotor
  5. Once enough to go inside a cordless drill chuck - grab the nichrome wrap and turn on the drill in reverse to start wrapping. Tension the sleeve against the rotor
  6. Wrap away! A person should be able to wrap 4 feet long just by holding a corless drill
