Hi all,

We had a question come up about printing ABS at high speeds, and if it was actually feasible to print large parts at 200-250mm/s. So I did a quick video showing one of our machines running this part (https://www.thingiverse.com/thing:441087) at 80% scale.

You can see the video here: https://www.youtube.com/watch?v=w7r99pASteI

The challenge was to find an object that:
  • Was large enough that we could run fast without hitting the layer time cooling limits (layers must take longer than X seconds in order to cool sufficiently)
  • Was intricate and detailed enough to be a good test of the printer's ability to produce the correct geometry at speed
  • Was not so large it would take a whole day to run


The print settings:
  • Printer: Fusion3 F306
  • Nominal print speed: 200mm/s (for everything - perimeters, infill, and support)
  • Slicer used: Simplify3D with F306 ABSpro preset
  • Non-printing travel speed: 500mm/s
  • Layer height: 0.15mm
  • Nozzle size: 0.4mm
  • Infill: 10%
  • Firmware XY acceleration: 3600 mm/s^2
  • Firmware XY jerk: ~30
  • Extruder retract and prime speed: 350 mm/s
  • Support used: yes
  • Total print time: 11 hr and 14 min


The part came out really nice! While there is some surface rippling as seen in the pictures, overall the features are still precisely formed. No part of the model is missing or failed to build. There is also no hint of layer delamination!

There were only 5 changes made in the preset to go from our stock print speed of 100mm/s to 200:
  • Change the layer height from 0.2 -> 0.15
  • Increase retraction from 4.5mm -> 5.0
  • Increase extra restart distance from 0.02mm -> 0.07
  • Increase head temperature from 260C -> 272C
  • Increase print speed from 6000 mm/min -> 12000 mm/min


Let me know what you think!
