Fast 3D Printing: Tuning to the Max

Input Shaping + Pressure Advance = the basis of fast and high-quality printing

Print speed isn't determined solely by the slider in the slicer. Four physical factors determine the actual upper limit.

Volumetric flow

Tryska 0.02 in / PLA: ~0.59–0.79 in³/s | Volcano: ~1.18–1.57 in³/s

Acceleration and Jerks

Without IS: max. ~0.1 in/s^2 | With Input Shaping: 0.2-0.8 in/s^2

Input Shaping (Resonance Compensation)

Eliminates ghosting at high acceleration - necessary for speeds >5.9 in/s

Model Cooling

At high speed, each layer solidifies faster → more powerful fan

• Why speed ≠ quality: When increasing speed without Input Shaping and Pressure Advance, under-extrusion, ghosting and corner accuracy deteriorate.

• Printers for fast printing: Bambu P1S / X34 °F, Prusa Core One, QIDI Q1 Pro or Voron have Input Shaping and Pressure Advance integrated from the factory.

Recommended option

Slicer settings are key to maximizing speed without compromising quality. The default profiles are conservative.

Layer Thickness

0.01 in instead of 0.01 in = 50% fewer layers

Extrusion width

0.02-0.02in with 0.02 in nozzle = more material per pass

Cooling

100% from the 2nd layer - necessary for layers >1.2 in/s

Pressure Advance (PA)

Calibrate for each filament - compensates for nozzle pressure

• Biggest gain: bigger nozzle Changing to a 0.6 or 0.03 in nozzle is the biggest jump in print speed. Not suitable for detailed models.

• More layer = less Zeit: A layer of 0.01 in (instead of 0.01 in) reduces the printing time by up to 33%. The resulting strength practically does not change.

• Hardware limit: A common hotend with a 0.02 in nozzle will max out at ~9.8-11.8in/s with a 0.01 in layer. Above, under-extrusion is already occurring.
