Hey everyone!

I’m currently working on my own Delta design and I want feedback from others to get new insights. My Delta is all based on 3 main aspects: Rigid, Nice and Quality.

I have a basic frame now, and I’m willing to hear your reactions on it. What do you think is good, can be better, is waaay off or is super smart!

Some information on the design:

  • Corners are all aluminium, so no printed parts here
  • Effector and carriages are the only printed parts for now, wich will be printed in XT-CF20 on 100% infill. Super rigid!
  • 12mm magnetic balls are used here, still hesitate about going with 14mm
  • N52 magnets used
  • MGN-12 carriages
  • Dimensions: 40x40x40 (triangle) 700mm height
  • 220mm diameter printing area, 350mm height
  • Driven by a DuetWifi board, 0.9° stepper motors, 24V, and an AC powered heated bed.
  • Delrin used as rod end to rotate around the balls
  • IR sensor for probing.
  • E3D Hotend

Please feel free to come up with suggestions if you think some of these can be better!

Questions:

  • What extruder to use? Was looking into Bondtech or E3D Titan
  • What distance between the parallel rods, now it is 46mm, is this important?

I hope to get some input!

I might go for E3D Titan in flying extruder setup.

Looks pretty good to me. If you can use a floating/flying bowden tube extruder you will get better feed and retracts.

As for rigidity adding side panels on the 2 back walls and a door on the front will improve the rigidity greatly. I was surprised how much the delta frame can flex at speed and the smallest of movement will add ripples to your print. Also adding sides and a door means running ABS will be a breeze.
